RE: Goldberg Tiger Club
[quote]ORIGINAL: mrshea oh man i lost my tiger last saturday. I heard flutter on a pass over the runway figured it was an aileron, End of the runway pull straght up probably harder than i should have, Hammer head and come staight down with no elevator. Total loss was able to save engine, Reciever and battery pack. I hit so hard that it put a hole in a 6 oz hard dubro tank and stripped the gears of the servos except one. The elevator servo. Post crash examination showed that it looked like the control horn pulled out of the elevetor i'm assuming on the way down. I'm totally bummed about but now i can build a new one with some mods to make it a little more responsive. Phil #19 [/quote] Sorry to hear that. Aileron flutter is common on the Tiger using the supplied hardware. I had it on mine early on and I'm only flying on 35AX. I quickly put in a dual aileron set up and no problems at all after that. Build another one soon. It happens.

Check your Field Box Battery
Noticed some fluid on the bottom of the flight box and when I took the sealed lead acid battery out, found black stains under it. Turns out the case seal on the four year old battery has failed and the battery acid is leaking out. I trickle charge it at 25 mA and hope that was not the cause. Luckily caught it fairly early, but it still damaged the wood a bit. Am going to install a plastic case to house the new battery to avoid this in the future. So..... Check your battery often.

RE: What's the proper method of a barrel roll?
[quote]ORIGINAL: 70x7 I guess axial rolls are what I'm really trying to do, sorry for the incorrect terminology. Barrel rolls, as you describe, sound even more difficult. [/quote] Barrel rolls are quite easy with a trainer. Dive for speed and then start a straight climb of 45 degrees. Before the airplane slows down, feed in aileron and rudder and keep them there until the airplane rolls around back to upright. Barrel rolls are a positive G maneuver so you are not feeding in elevator. Just leave it alone as you do a barrel roll. For learning axial and barrel rolls, make sure you start on a good "up line". You will get there by just practicing more.

Can birds perform loops?
We have a bird here in Northern Thailand that sometimes comes in the evening to feed on bugs over our pond. It is much more aerobatic than a swallow and it can dive straight down to the water and pull out inches from the surface and do rolls as it climbs out. Still trying to identify it but these occasional air shows have us wondering if any birds can perform a loop. Rolls, hammerheads, split s's can be observed, but never a complete loop. Here is a video that might be of interest as well. Still no loops though! [link]http://www.youtube.com/watch?v=p-_RHRAzUHM&feature=player_embedded[/link]

RE: Good 2nd Low Wing?
[quote]ORIGINAL: Smasher12 My second plane was a Carl Goldberg tiger 60 with an OS 81 four stroke. The tiger is a lot like the four star by looks. I loved this plane! Very simple very easy to handle and gentle flying. It is also capable of doing your basic rolls,stall turns,loops, etc. It's really the plane I learned to fly with other than just circles with a trainer. Still have that bad boy in the hangar as my ''when all else fails'' airplane. Good luck with your search!! [/quote] Lots of good suggestions on this thread already, but my vote on a first low wing is also the Tiger. Just a straight forward, light, and rugged airplane that can have you doing dozens of beautiful Cuban 8's on every flight. My favorite windy day ship.

RE: Its Official... I Ordered a Kit
Congrats Bill on getting started. Kit building is very satisfying enterprise and I am sure you will enjoy it. You mentioned you have sandpaper, but you might take some time and make a few sanding blocks. Most useful to me are 10 inch long 1 by 2 firring wood wrapped in various grits of sandpaper. (I use thumb tacks on one edge to hold them on.) I also have a few 1/8 and smaller ply sticks that I glue sandpaper onto for tight places like rib cut outs. Also consider getting one of the small aluminum miter boxes so you can hand cut stringers, tri stock, and other small straight cuts. You can buy an Exacto saw, but I find myself usually using a hack saw blade the miter box. No handle, just the blade. Have fun on the project!

RE: cessna 182 Control surfaces
[quote]ORIGINAL: RICMOD5634 What are all the triangle strips for on the control surfaces. I have seem them on other airplanes to. Do they actually have a perpose? Rich [/quote] Ricmod..... Could you clarify a bit more on what parts you are referring to? I owned a C182 with a Horton STOL kit and part of that mod was to add small triangular assemblies on the wing which functioned as laminar air flow disrupters. This helped keep the air flow attached to the wing and lowered stall speed so one could fly slower approaches. On a model I doubt very much they would do much do to the low Reynolds number of RC model wing dynamics, but they would look scale on the right aircraft. Edit: Sorry for the old school terminology. More recently they are called vortice or vortex generators. Here is a link.... [link]http://en.wikipedia.org/wiki/Vortex_generator[/link]

RE: tower pro servos
If you are referring to the blue mini servos with a single mounting hole on each end, I have been using two of them for over two years on a Tiger II that flies regularly. (One on each aileron.) I can buy them for about six bucks US here and was wary of them at first. Friends use them here and they are actually fairly well regarded. They sure do not look like much, but they seem to last well. I kept an eye on them at first thinking I would have to change them out for something better but so far so good.

RE: Best sounding model
I would be curious how he has that ship hinged and the control surfaces counter-balanced to keep it from developing flutter. I saw a P-38 flying like that years ago during Scale Masters and all it took was a few seconds of flutter and one of the Quadra engines was going through the parking lot like a canon ball. Luckily no one got hurt. That Mustang is really moving! I guess the jet flyers have the same problem. On an aside, 200 cc's is a lot of engine. My wife and I have almost 25,000 miles touring Thailand on a Honda CBR with a 150 cc engine.

RE: LiPo Life
Thanks for all the good information all. A few take-aways: -Do not store fully charged batteries. -Do not fly and discharge more than 80 % of capacity. (see note) -Do not charge at too high a rate. -ESCs do not protect batteries. (I agree with poster that said they should be redesigned to do so.) -LiPo quality varies from manufacturer to manufacturer. Note: How does one know this point when having a good time flying? It sure seems that this kind of information should be in a booklet or more easily obtained rather than getting it from the school of hard knocks!

LiPo Life
I am new to electric flight, although I did fly an electric plane for a while two years ago. I was recently given an ESKY Hunter coaxial helicopter and it has been a lot of fun. The original LiPo puffed up after about 12 flights so I bought a new one at the LHS. They told me to not take it out of the heli and to avoid handling the battery. Okay, had not heard that before and the new pack has about 30 flights on it and flight times are about half of what they were when it was new. Is this loss of flying time typical after 30 cycles? I am using the balancer/charger that came with the Hunter. Seems like batteries should last many hundreds of cycles with no degradation.
