unfortunately a bad RX switch put an end to my P-47 after about a dozen flights or so.
I've started using dual battery/switches on all by planes now. Never again do I want to crash due to a bad switch!

Unfortuately there is no easy way to test a switch except to swap them out when they get some milage on them. Dual batteries in a .60 size plane maybe a bit much, but dual switches, I could see. A five cell pack with dual leads, dual switches and dual leads going into the receiver.
The new LiFe batteries are small and light. In my TF P-40 I am using two 1300 mah LiFe batteries and two Radio Shack toggle switches. Before each flight I turn on each battery/switch independently to see that it works. During flight either one can fail and I still have power....both systems would have to fail in order to have a total failure.

Add me to the list. I've always liked the P-40 and it's my favorite WW2 warbird. The early variants like the B model really capture that golden age "pursuit" vibe nicely. I'd love to do one eventually in a natural aluminum finish with early USAAC markings. The only ones I've owned are FF variants (Comet, Guillows) and my first nitro, a Testors Fly-em P-40. But one of these days...

If you believe this guy ( http://www.hangtimes.com/parallel_packs.html ) you don't need a "batt-share" with parallel packs. A cheaper alternative is to use two small voltage regulators like these ( http://www.hobbyking.com/hobbyking/s...idProduct=4319 ) between the switch and the receiver. This is what I'm going to do....two VRs for less than $10.

What are the landing gear options for an 82" P-40? I'm aware of Sierra, Robart, and ESM....anything else?

Possibly the Yellow Aircraft retracts? The Yellow airplane is 86 inches but the gear may be close enough for government work. I have a set for my future P-40 scratch build and they are beautiful pieces of workmanship.

Never heard that one ... but that sounds good too. I wonder what the weight difference is between the two setups?

Looks like a good group to monitor for ideas and input. I am ready to maiden a Jerry Bates P-40 with a Moki 1.8, Century Jet mains and Robart mechanical tailwheel. 3/4 oz glass with Latex colors and Warbird colors catalized clear in Matte finish. All lettering and rondells were masked and spray with latex also before clearcoat. My target was 20 lbs and I came in a 1/2 lb under that so hopefully it will be a good flyer.

Looks great and should be delightful at 19 1/2 pounds wireman. Look forward to your flight report, good luck!

Please add me to the group. I have a fairly large collection of 60 size warbirds, mostly Hanger 9 with Saito 100 engines. They all hang from my garage ceiling and give me great pleasure everytime I am in the garage.

I wanted to add a P40 to the group and last summer made a super buy on a used Hanger 9 P40. It was in great shape, OS 91 with one of the real, functioning exhaust system. The only problems was the stock retracts were non-functional. I immediately bought a new set from Hanger 9 and eagerly went to the field for my first flight. I found the plane was a very good flyer but it wanted to nose-over on every take-off and every landing. On an RC forum on this particular plane, I found that Hanger 9 had put the CG to far forward in their instructions. I moved it 3/4" aft and bushed the mounting of the gear to tilt the struts and wheels farther forward. This made the plane much better but the gear only last for about 5 flights. I now need new gear again. The plane is a peach to fly with no bad habits(much like a trainer) but sure does like to nose-over.

I am looking for a set of electric retracts that will drop in. Lados seem to be unavailable, Wingspans having birthing problems, E-Flight still be developed. I love the E-Flite retracts on my Top Flite P47 Razorback. I plan on putting them on my Hanger 9 Spitfire and P47.

I love the plane, just need better retracts. Any ideas??

I would ditch the Radio Shack Switches as they may or may not hold up under vibration and go for something designed for the hobby.

It has been shown that a failsafe is not required and just adds another failure point. Diodes would work fine if your worried about it.

Two voltage regulators in parallel will not function properly and adds failure points.
