RE: Angles of lean
Disco, Here is the the major difference, Speed. A properly designed multi hull on a beam reach will have one hull out of the water. Now boats generally like to head up into the wind during a puff. On a cat, that puff wants to increases the heel, and if your not paying close attention and controlling your sheeting, the boat wants to capsize to leeward. Second problem especially in r/c is the width of the boat and it's performance around a mark. A cat needs more manuevering room to tack. Third, and the most scary of all is running downwind. Lets say your heading on a run in a good breeze, and a strong puff hits you. A cat will want to bury the bow. This leads to a pitch-pole. The the boat capsizes stern over bow. It can be avoided, but because a cat gernerally is sailing faster, your reactions have to be faster as well. Multi-hull sailing is just more difficult. While there are multi-hull classes, especially in Europe, they are not near as prevalent as monohulls for these reasons.

RE: Angles of lean
Hi Disco, The rigid sail, or wing for sailing has many technology issues that really apply to boats only. On an airplane, a non-symmetrical foil is used in most aircraft, with a symmetrical foil used for hi-performance aerobatics. Problem with sailing is, you just about have to go with a symmetrical, as the sail does not have a constant angle of attack that can be controlled through the vertical plane(elevator-elevon). The angle of attack is never consistent for a vertical foil that moves horizontally through a variable direction and velocity (Wind). Wind provides your thrust in sailing, and is not overcome as in flying by the use of a prop. Wind provides your 'thrust', and you must be much more aware of it's effects than in flying. In flying wind is a consideration to take into effect, in sailing, it is your source of power, and everything else is a consideration. This is why sailors constantly need to sheet and trim the sails to the 'apparent wind' and why 'flexible' sail material is still used. On a rigid vertical wing, as the "sail" cannot form to the apparent wind, but must be tilted to it. (i.e. rotating Mast, adjusting foil, etc) This creates a weight and complexity problem that the racer making a course would just as soon not deal with. Wing sails work great in one direction and at limited apparent wind angles, but their perfomance envolope is relatively narrow, and the controls cumbersome. This is why they are not used for course or match racing, but primarly for speed trials in one direction, and perhaps the reverse course. They have the potential to be much faster in a straight line over a "sailed" boat, but they give up almost all their manuevering ability to do so. Kind of like racing a rail dragster against a BMW. The dragster will win if the race is 1/4 mile long and straight, but the BMW will eat it for lunch once a turn or two is introduced, especially over a distance. with multiple turns. As to your specific question why wings are canted leewards (away from wind) this is due to the wings inherint stability. In a 'puff', the loading force on a rigid wing can increase more rapidly than any sail trimmer could adjust for. This is a saftey issue. By canting the wing, the loading is delayed, and less force driven to the hull. This improves the stability of the boat. Without the delay, the chance of being dunked and turning turtle becomes extreme. Just a word or caution. You are a novice to sailing, and you are about to undertake the two most challenging sailing issues there are. First, control of a multi-hull(catarmaran) which is much harder to sail, especially in R/C, and then adding a rigid wing sail that quadruples the complexity. This is not beginning sailing!!!!. I'm not trying to squash you here, but, this is like going from a 40 size trainer with an instuctor, to going to a twin turbine powered R/C F-15 on your second outing to the airfield. You are bound to pitch-pole, or capsize this boat, find it un-controllable, and decide that R/C sailing sucks. I would suggest you learn sailing from a keel boat type, I.E. Victoria, Seawind, Victor, Northwind, or what ever else they happen to sail in your area. Learn the rules, and learn to race and control a boat. Then move to a multi-hull; then decide about rigid sail wings. This will save you a lot of money, let alone heartache. Chris

RE: Anyone else building muti-masted ships (pics)?
If you got weeds, you need full keel boats, i.e. like the J or EC12. Our pond has a serious millform problem, and the only thing that can sail in it if the weeds aren't treated by sunblock are 12's and J's. Thoes fin keel boats just snag and become "marks" on the course. [:D] Which makes me much more competitve[sm=lol.gif] Chris P.S. How many winch servos does that boat take? Must be hell on batteries.

Airtronics/Futaba
Hi all, I'm a bit confused on servo wiring and RX compatability. I have an Airtronics Vanguard TX and Airtronics 92765 FM Dual Conversion Narro Band Receiver, that I just inherited. The RF check date on the TX is 1/96, and not being an Airtonics owner in the past, is this receiver compatable with Futaba servos?. This has the "z" connector, ( I think, as the futaba plug will fit the receiver if the polarity tab is removed). Does this receiver require the Futaba plug to have the wires moved in the plug to work. (my local hobby shop doesn't have Airtronics to futaba or futaba to airtronics adapters) Also, not knowing anything about this receiver does it have BEC. It does not state so, but Channel 7 is listed on the body as B/7 Thanks for any help, Chris

RE: SAIL Engineering winch
As an EC12er, I did not recognize the type of winch your using. If you have kraft electronics I'm assuming your have an early model of the EC12. You might want to post this question on the [link=http://www.ec12.com/discusion/default.asp]EC12 Discussion Forum[/link] Perhaps one of the long time 12'rs might recognize the winch your talking about. Currently folks are mostly using RMG, Futaba 5801's, Old FP-S10's and Hitec 725BB Drum Winches. There are still a few probar and dumas arm types out there. By the way, don't expect your 12 to outperform a Laser. The Laser is a planing hull boat that is pretty quick. The 12, well it's a full keel boat, and handles like it. Graceful, elegant, and hard to master, but not a speed demon. At around 23lbs, she give up a lot in displacement to sail area ratio, and has a much higher wetted surface area with less righting moment than a the Laser with her long deep fin. Chris

RE: My boat is back
Hi Alden, I'm not sure if this boat belongs to any class, It looks like a 36/600 or IOM, but you state an LOA of 50 inches, or 1.25 meters, so I can't I.D> it. You might want to post this question and pictures on [link=http://www.rcsailing.net/forum1/default.asp]RC Sailing[/link] but for the mast 3 suggestions come to mind. First is carbon fiber, second is a sailset grooved aluminum, or third, an airfoil shaped grooved mast. Check out AMYA.org, and go to the supplier page. Before you do, please get the boat identified. It will definetly help you in determining your needs. As to sails, sail cloth is going to be extremy heavy (dacron) If you plan on making your own sails, (which is quite difficult to do properly) I would recomend Trispi or Icarex(toray). A better suggestion is to contact a sailmaker. You've got a really nice hull there, that looks to be a very high performance boat. Let a pro do it for you. It might cost around $120 u.s. , but you'll get a set of good sails that will really optimize the boat. Plus a sailmaker can help you determine the correct cut of the sail for the type of conditions your going to sail in. Chris

RE: setting up winch system
I'm a big proponent of the closed loop system using a drum winch. It costs a bit more than an arm servo, but , the travel has always seemd more realistic, and has a higher reliability factor than the single take up approach and turning block. Ulimately though, it really depends on the boat your using, the available room in the hull, etc. Check out my ec 12 rebuild, [link=http://home.triad.rr.com/intrepid1582/intrepid1582/_sgt/f10000.htm]Intrepid 1582[/link] Again , there are so many variables that you haven't mentioned, its pretty hard determine the best approach.

As I was about to purchase a new battery for it, should I go with the data plate as the frequency band?. If it is a 72Mhz, it's useless to me and is not worth replacing the battery.

WHY WE SAIL?
This started on on other board, but I thought it might bring a bit of relevance to as all. Hi Grampa, It’s been a long time. I want to thank you for all that you made me. It’s been such a long time since you passed, but your memory is never far from my soul. I still sail, as you taught me. But I had to take a long break between our last sail, and my current ones. The boats are smaller, but are as pretty as “Juno II�. I now have my own boat, I’ve refitted her, and blazoned your initials on her gunwales. She is fast and right. She’s a miniature version of what your always wanted. A full-keeled beauty, only in 1/12th scale. I can’t sail upon her, but I can sail her with you by my side. Though it’s been well over 20 years since we together stood watch at the helm of “Juno II�, you always seem to be there, to steady my hand upon the tiller, and sniff the shift of wind. Thanks for making me the master of your vessel, even at the tender age you did. Few would give a teenager, not only the helm, but his pride and joy. Thank you for teaching me responsibilities beyond my years that have followed me since. Thanks for showing me the love of life you always had . My proudest day, was the day on the dock you told me, ‘set for sail‘, and to ‘prepare take her out‘. When I asked where, you said ‘where you want, your going alone‘. I was terrified at the thought of taking “Juno II� out, with out your steady hand nearby. I was also terrified of not taking her out, and what kind of sailor you would think I was, by not rising to the challenge. I learned more about my self that afternoon, than I have ever learned. I also learned more about life than I could have dreamed to know. I learned that I could master my way without help, and bring the boat to dock, but more importantly I learned how valued trust is. Someday, God willing, we will sail together again. I dream of hearing you bark out, “hard to lee�. “Hard to lee’, Grampa, Hard to lee, and sheet in, light on the helm and follow the sea.

RE: The perfect pond?
Ok Rob, you asked, and here's the wish list. (And if I ever have enough money to buy land and open a hobby shop, this will be on site-kind of like a 20 acre RC Boat event stadium) Pond- At least 800 x 500ft. (Bigger than many current EC12 Sites and large enoug for a good modified Olympic Course). Depth at shore line at least 36inches. Power retractable bouys arranged to take advantage of prevelant winds. By using a control panel, the course can be changed by raising or lowering bouys. (Did I mention this needs to be on a Plateau with no wind obstructions.) Hydraulic Launch and Recovery Cradles. (This is the cool part- a cradle that you place your boat in that lowers or raises the boat into/out of the water. No more kneeling in goose crap-several would be nice.) A wide asphalt walkway around the pond so you don't fall into the muskrat holes as your following the boat around the course. A covered pavillion with set up tables and benches so each sailor has a covered area and room for his gear, close enough to the shore to control the boat in the event of rain. Each table to have electrical outlets for chargers, etc. A snack bar in the pavillion. A covered spectators area. Easily accessible restrooms. A Hobby Shop on site that carries RC Sailing parts should you have a breakdown. Said hobby shop also needs a workshop area available to boaters for repairs, assistance, etc. A storage facility where folks can store their boats, sails and equipment with out having to transport them. Hawks on sight to eliminate Canada Geese!!! Open to the Public with rental boats and instructors available. Close to major roads/highways so anyone can find it. A clubhouse with bar for all us RC'ers. Adjacent to a public park making it easy for folks to find us. I wish this sport was more well known, then maybe my business model would work. Chris

RE: Share electrics with R/C plane?
I've got to agree with LtDoc. But, it may not be quite as expenseive as you think. A 75mhz radio for a two channel boat (Nirvana, etc) can easily be had for around new $50. retail. Futaba 2ER or JR Beat Gear come to mind. If your willing to buy used, these are on ebay all the time and run about $25 with servos and reciever. If the boat will ever compete, you'll need to be on a surface frequency anyway as both AMYA and AMPBA (sanctioning bodies for RC sailing or RC powerboats) mandate it. As to flying R/C. LTDoc is dead on. Don't risk losing control of the aicraft because some one nearby might be on 27 or 75mhz(surface)(Truck, car, or boat) you might not know until you've lost the plane. I would highly recommend that you contact a local AMA R/C Club for training (instructor) on RC flying . It's not as easy as all the packaging on the model makes it out to be. If' you've never done R/C flying, your most likey to crash, ruin your aircraft and demoralize your child. An instructor is vital on R/C aircraft. If your going to let him into RC, especially planes do it right. Follow the rules, (Frequency assignents, fly at approved locations {insured} and get an instructor.(AMA Qualified) You'll actually save a lot of money this route by doing it right. (less repairs). Keep in mind, that R/C airplanes can easily do 40 to 60 miles an hours. Loss of control, is a serious event and can be not only expensive, but extremely hazardous to anyone on the ground. Be Safe!!! Until your ready to invest in highend band switchable radios {$350) or more, plus the RF modules($75+), don't try it. Get a cheap 2 channel surface for the boat, and an inexpensive Air 4-channel (72mhz) radio for the plane. (Total of maybe $175 total at a hobby shop). Boating is easy, but flying NEEDS AN INSTRUCTOR>>> You and your son wil enjoy the hobby, much more by following this advice!!! Chris

RE: EC12 Rig - via the Internet...attaboy!!
Hi Rob, Got to agree Rick's sight is great. In re-fitting my twelve, I've stripped the deck off, and had Rick send me a set of the Rhinehart Plans. Used them as templates for the deck ribs, along with his measurements for mast position, fairleads etc. Came up with my own radio board design loosely based on Bob Merserau's closed loop article in AMYA Quarterly. Only problem I've run into is weight. The orginal builder of the boat put on a three pound deck(not kidding). My new deck is 1/32 birch 3 ply with epoxy and glass underside, and strait epoxy tops side. I was a little sloppy on the first one, and am redoing it to get a better stain job, but weight with ribs is down to 8.75 ounces. Now I've got to add ballast as my total boat weight with rudder is short by a good 2.5 lbs. The advantage to this is now I can have a multiple ballast system to target waterline for most conditions, and adjust the bow angle simultaneoulsy. I'm keeping a running file of pictures through the process of the rebuild, and promise to post them somewhere. My next major project is a new rudder. The one on the boat, is a bit small, and oddly shaped for a 12. Luckily the rig won't require much fusing with, as I replaced all that stuff when I boat the boat, and used the EC12 manuals then. In Feb, I'm getting with Bob for Sailmaiking 102. This time we will completely cut and build a full a suite in Trispi 25. (I needed new sails, and this will be a lot cheaper than a new set of Carr's) This is going to be a fun off season. [code][/code][:D] Chris

RE: Sail material
It depends on what your ultimate goal is. If you're cutting sails for a strict static display, dacron is the probably the best choice. If however you plan on actually sailing, and more specfically, competing with the boat, I would definitly advise you to have them professionally made, unless you have a home builder nearby to assist you in cutting and broad-seaming. I have a couple of articles posted in my Northwind Group at yahoo. In the files section (you'll have to join the group to read) there is a folder on "Sailmaking". [link=http://groups.yahoo.com/group/Northwind36-600/]Northwind 36-600[/link] To cut sails that are efficient will require a camber board which can be homemade. But by the time you build the board, obtain all the materials, it's going to end up being far easier to have them cut for you unless you've got someone who knows what their doing to help you out. As to the actual sail material, quite a few choices her. Mica film works fine on smaller boats, but creases easily. The fabric of choice these days is Trispi. This is a transparent mylar with re-inforcements imbedded in the material, comes in 25, 40 and 75 weights. (higher being stronger). Two other good materials are synthetic fabrics "Icarex" and "Toray" These come in many different colors. I've included a link for these items where a lot of us EC12rs obtain it. Trispi is listed under films, Icarex (being phased out for the newer Toray) are in the fabrics section [link=http://www.citystar.com/hang-em-high/]Hang-Em-High [/link] Hope this helps Chris

The biggest will pull tree stumps. Made in the U.K. [URL=http://www.whirlwindwinches.co.uk/]http://www.whirlwindwinches.co.uk/[/URL] And finally, Graupner Regatta 1, 2 and ECO. Not available in the U.S., but can be found on German Hobby shop sites, and may be available in EU or in the UK. Sorry no links. I did inquire with Horizon Hobby about special ordering one as they are Graupner's U.S. Distributor. Cost was exhorbinant, and item was not returnable. One last source, check EBAY, occasionally the older Futaba S10 and S14 winches come up. (I manged to win the auction for one about a year ago). These were made up to the early 90's. Excellent winches with metal gear trains. Considered bullet proof. THe S10 is a little weaker than the Hitec, the S14 more powerful. The are heavy at close to 8 ounces, but are highly desired by EC12 sailors for their reliabilty and resolution. As to servo comparisons for the 525, check this sight: [URL=http://www.fatlion.com/sailplanes/servochart.html]Servo Comparison Chart[/URL] Hope this is the info your looking for. Chris

Hitec Futaba Crystal Compatability
Hi Mike, Are Futaba 75mhz Dual Conversion FM cyrstals compatable with the Hitec Laser 6(75mhz Transmitter and receiver) My Futaba 6YG went out the tail end of the truck (along with my sail tool box). Looking at a replacement and have found a great deal on a Used Laser 6 with RX in 75mhz, but replacement cyrstal sets (Futaba's that I have) may not make this such a great deal. I have have to have at least 4 sets for regatta enrollement. Thanks Chris
