RE: Tomahawk 1/3 Wilga by Vogelsan Aeroscale
Well, Frish also has a 1/3 scale version but they do not have a US distributor so it would have to be shipped from overseas. It is a fiberglass fuselage and sheeted foam flying surfaces. I just liked the looks of this one and was wondering if anyone has purchased one yet. Thanks

RE: MOKI RADIAL Care and Maintenence
In reference to the APS fuel pump: Am I missing something here? If there is a simple "T" on the feed line to the carburator, back to the fill line, how is any fuel pressure applied to the carb? Would not the fuel follow the path of least resistance right back to the tank? I have been running mine without a return on a 50 and a 250 with no problems. Dr. Goetz: could you be a little more specific why the return line is recommended, please. Paul

Just for your info, The RCS 4 stroke tool kit that I purchased with my 250 contains a .007" feeler guage for setting the valves as well as an oiler and wrenches to fit the valve nut. This is a nice little kit to own and is still available from Troybuild here .http://www.troybuiltmodels.com/items/RCS4STROKETK.html Paul

I had two large Sierra air tanks. I was able to hold pressure both up and down for several days. I ran 110lbs of pressure before flights and landed in excess of 100lbs. I was not able to determine why it would fail one time and not the next or I would have addressed it. Thanks for asking..........

RE: CARF F4U-1 Corsair build thread
I loved to fly my Corsair but always dreaded landing it due to gear failure (ripped off doors 4 times) so I passed the airframe on to a good friend for 0 cost. We are both very experienced modelers. After workin over the gear for the umteenth time, it failed on him on a greased landing. He emailed Andreas and was told that after many complaints of gear failure and ripped off gear doors Comp-Arf has agreed to have the landing gear re-designed. Please direct your questions and concerns to Ray Labonte. The more inquiries, the faster the job will get done. Not having a positive lock on a 60lb airframe (not to mention a hugh investment) is insane....................... Going the Locked & Down conversion may be the way to go............... If that conversion works out, I may ask for my airframe back.................Please keep us advised of your progress on the conversion................

I posted things that were different on my fixed wing version compared to Sam's folding wing version. I don't get it................ the information is here and you don't take the time to read it. You would be much better off e-mailing Sam with questions rather than the factory (that is also posted here) I for one would like to thank you Sam for taking all the extra time to post in such great detail.

RE: ESM Dornier DO 335
Jim: I fly several large twins on electric, up to 50lbs. You need to throw out all you know about gas or ethanol engines. Without getting technical, electrics fly on watts. You need to buy a wattage meter and see what kind of wattage your motor is putting out, then you need to know how much your plane weights ready to fly. Here is a general rule of thumb for electrics 50-70 watts per pound = minimum level of power for lightly loaded slow park flyer 70-90 watts per pound = trainers and slow flying aircraft 90 - 110 watts per pound = fast flying scale models and some sport airobatics 110 -130 watts per pound = advanced airobatics and high speed aircraft 130 - 150 watts per pound = lightly loaded 3D models and ducted fans 150 - 210+ = unlimited performance for any 3D models So, just for giggles, I read a few comments back that the 160 on 10cell puts out 2800 to 3000 watts. So lets take 2700 and times it by both your motor for a total output of 5400 watts. (by all means please put a watt meter on your setup). Then back a few threads you said your plane weighted 31 lbs. So, 5400 divided by 31 equals 174.19 watts per pound. Perfect if you want to hover it. Now you have taken the guess work out of it and know what the power level will be. Running on just the front motor will give you (2700 divided by 31) 87 watts per pound which will definitely fly it with authority. As far as your batteries, I did not see any pictures of where they are located. Can you put all 4 lipo's up front? As said in the last post, you need to extend the speed controller to motor wires, not the battery to speed controller wires. You will loose a little power running them that far, but you definitely have a little room. Hope this helps. Paul

RE: Spitfire CARF-Models 2011 Build Thread. Started by Lazy Eight & WARBIRDRCER
The landing gear must be outward as far as possible. To create more room to do so, I ground off the upper corner of the landing gear brackets almost up to the mounting hole. I then cleaned all the excess glue off the rib where the rail is glued to it. I had a lot of slop between the rails and the brackets. I used a piece of hardwood almost 1/4 wide and glued it to the rearward rail as the gear needs to go forward. I then sanded the rails so that when mounted, the strut is directly in the middle of the supplied cutout slot in the wing. At this point you have the gear without the wheels mounted and the leg is retracting into the slot pretty much in the center and you have made a little cut out for the scissors. Be sure and mount your wheels at this point. You need to set the amount of toe-in you want as it will affect where you need to enlarge the wheel opening. You will probably have to remove all that you can from the front and not so much on the rear. While enlargening the wheel opening, be sure and have your wheel cover handy as you do not want to have the hole larger than the cover, of cource.

RE: Spitfire CARF-Models 2011 Build Thread. Started by Lazy Eight & WARBIRDRCER
David is right. I have a photo of a real Spitfire wing on a jig at the factory. I shows the wheel way to the rear of well. There are numerous people flying this airplane. All complained that the retracts were not drop-ins but I have not heard of anyone re-designing either the retract, the wells or the doors. I am by no means an expert but I did get mine installed and they are working just fine. You have to go in knowing that during retraction, the wheel will come close to hitting the front of the well and end up in the rear and that the wheel well opening will be somewhat oval. The fact that the opening is not completely round is moot since the wheel cover is designed to overlap the opening. I don't know if this is right or wrong it is just what it takes to complete the job with what you have on hand.

RE: COMP ARF 110
DDay: I hope you are right but hold off your judgement until you get them in the wing. They usually require adjustment of the collar on the upright to increase retraction into the wing so the doors can close. In your case of the fixed wing version, they need to retract until they very nearly hit the carbon fiber center wing spar/tube holder. This changes all the geometry on the scissors. You will see what I talking about when you get your wing..................LOL Paul

$3290 - Ouch!!!!! Not saying it is not worth it but for $600 more, I can have a Comp-Arf Spitfire (1090), P-51 (1190), and a plug-in wing Corsair kit (1695). I think I will wait for the kit which should come in around $1600. I have the Corsair and am just finishing up the Spitfire. I was waiting for the Razorback to come out before I decided between it and the P-51 for my next project. Will definitely be the P-51........ I don't want another 10K plane like the Corsair......

RE: Comp ARF Spitfire build
I was worried that the skirts would flutter in the breeze, so I left the axles long and slotted the skirt for compression of the gear. I then used a nylon washer with a wheel collar on the outside. Now I can compress the skirt tight against the wing skin. Worth a try I thought.

I decided to use servo hatches like Comp-Arf does in their 3-D airplane wings. These are available from D Balsa and are the standard size. Not that hard to install. I also opened up the area around the retract mount area and fitted a plywood plate to cover as much as possible. Again, not that much extra work

[b]JPate147 -[/b][u][/u] How much lead in the nose did your friends plane take with the 3W-157? Is it the folding wing version or the fixed? If he flies it fast as you say, has he had any flutter problems? Most builders using the 12lb Moki radial still needed on average 2 to 4 lbs to balance. If you are not real careful, you will end up with 10 to 12 like Sam did. Just my 2c

RE: COMP ARF 110
Approx 25 flights on my fixed wing version with Moki 250 and Menz 32 x 14. JR8611 on ailerons and constructed per instructions. Every flight has had numerous full throttle fly by's 20 feet off the deck with hard pull ups then a roll. No hint of flutter. If I could not do that, this plane would be gone. I read somewhere that Darrell has made 150 sets of landing gear for this bird so there are lots of them out there and only a few complaints of flutter. (which so far have been resolved by the builders) My only complain about this plane is that the main gear does not have a positive lock down but that isn't Comp-arf's doing. I paid paticular attention to the main gear sissors in the last couple of finished Corsairs in this thread. All showed little if any over center throw which means they WILL fold on anything but a greased landing which I am rarely capable of. A good test of the mains is applying pressure downward on the scissors while pushing back on the strut. If you can break the lock with 100lbs of pressure, then you need to work on them some more. Also, pay attention to the rear bracket that the air cylinder attaches to. This has 2 bolts that lock it to the frame. However, the frame also has steel pin in the same location so the threads in the aluminum are very short (1/4 ") and will pop out on a hard landing there by stripping the threads. Or they will become loose after numerous landings and cause gear failure. I solved this problem with a small radiator hose clamp around the affected parts. I will be the first to admit that I am hard on this landing gear. I am just trying to let everyone know where I had problems so others may not. Geez this think looks and sounds great in the air. Paul

RE: COMP ARF 110
Jerry: Sorry to repeat myself, but is your airleron servo installed in the plywood rib? I noticed when Sam was setting up his aileron servo, his folding wing version did not have a plywood rib where our tube version does so he was forced to mount it on the wing skin. In so doing, you almost have to build a box around the servo to tighten up the wing skins so they do not flex in flight and create flutter etc. This is common to most Comp-Arf planes. Just checking to see if this might be your problem. Paul
