You can purchase 2000 ma triple AAA size nickle hydride cells to make up a very light strong receiver and servo battery, lost aircraft due to low voltage cutoff can be prevented. Norm

Correct. He tried to reset the ESC by moving the stick to the low position to get some throttle back but it was too late.

God Bless!

Status: offline 		There is a discussion on another sight that I thought is worth posting here. Batteries seem to be the second most expensive loss in a crash just shy of the entire plane. Most batteries get punctured by the motor screws protruding through the fire wall taking out $100-$140. This is a hopeful cure that may prevent it. I put two pieces of styrofoam together to equal at least 3/4 of an inch. One piece this thick would work as well. I glue it into place making sure I don't block airflow that enables cooling.

I hope this tip saves batteries and stops the adding of insult to the injuries!

God Bless!

Status: offline 		Been posting my results on other threads on other forums. Just a heads up on this model. The fire wall is weak. It can not handle prop strikes in the typical AT6 nose over that happens during landings. The openness and weakness set up by the adjustable motor mount blind nuts makes it likely that any one who flys it will eventually have failure and will need to make a repair on this. The nice air holes in the front are great but there is no way for the air to get out. I cut two nice round holes just behind the wing bolts in the fiberglass on the bottom of the fuselage. It gets much better cooling on the electronics and batteries now and you can hardly see them. Another item for inspection is the landing gear mounting blocks. Take a look at them closer. There is not enough glue on the blocks to handle the stress of grass landings. I recommend adding some epoxy and abit of glass cloth to reinforce this area otherwise your gona pull the blocks out eventually. If you landing on pavement it should not be a problem. The landing gear wire is unable to handle grass landings. If you like to touch and go you may not be able to retract the gear fully afterwards due the the wire bending and the wheel not alining with the wheel wheel. This will cause the servo to stall draining the battery of damaging the retract gear. The Robart gear looks neat but its not sturdy enough for the weight of this plane. When I was building this model, I to also noticed the elevators being warped. Did my best to straighten them out then glued the stabs to the tail since they buzzed when flying. At least the vertical fin is straight. I used a Higley brass spinner nut to compensate for the tail heaviness and it looks scale. The tail wheel wire is not flexible enough to handle more than a couple of landings before it comes off right at the bottom of the rudder. Stay tuned for the fix. Now, bear in mind this is off a grass field with a 1" crop. We use a golf course reel type mower. Its not some snaggle tooth field thats overgrown. Will post some picks of the scale additions made.

Status: offline 		PiperFan, all are notable points whether flying off of grass or asphalt. I recommend using Gorilla glue for the landing gear blocks because it's much lighter and adds great strength. There was another loss on takeoff due to not enough speed on takeoff and it snapped. Once again, like any warbird, it's important to maintain speed with this bird.

God Bless!

Status: offline 		Greg ...I'm also doing an AT6 and am having loads of problems with the retracts ...I'm using the JR Sport RT88 which I believe is the same size as the NES servo that you show ... the problem I have is that the servo has 180 degrees of rotation and of course, since its a retract servo, the end points can't be adjusted, if they could be at the transmitted then I wouldnt have a problem, so how do I limit the amount of travel? I've tried everything and am up against a wall here. Its alot more difficult than I thought... any help would be appreciated.

Status: offline 		Since retract servos have a 180 degree swing, you must adjust the linkage to have the proper length and offset for locking in both positions. You obtain this position by adjusting the clevis on the control rod and using an appropriate length on the servo arm.

Status: offline 		We finally had an opportunity to test fly the AT-6. It flew fantastic and performed perfectly! Plenty of right rudder was needed on take-offs. The recommended E-flite Power 25 motor provides great power for all maneuvers. When landing with the flaps, the plane will slow up quickly and fly just above the stall speed so be sure to keep power applied and let it descend to a touchdown.

Status: offline 		Hi everyone,

I recently decided to buy the Spektrum DX6i radio and replaced receivers on most of my RC Airplanes.

A month ago I went to my local club for the Warbird Funfly day. I brought one of the best models of my hangar, a superb World Model P51 Pettie .60 converted to electric. Now I've flown this model many times with my old JR radio and it was just converted with a Spektrum 6200 receiver.

Well you see it coming...as I was was going for a second round, all of a sudden the plane stopped responding...started a dive and crashed in the woods, thank god nobody was hurt.

I was able to recuperate all the electronic parts. I tested the receiver and it works fine, I'm completely puzzled about this and less confident than I was before in the 2.4 technology. Should I?

Status: offline 		Hi, this situation has occurred several times with Spectrum/JR 2.4 equipment in our area of SoCal as well. Those flying the Futaba FASST system have experienced no problems, we all wish we knew why. Most believe that it was the shut down reboot lag of a few seconds that did them in. I have switched all my large models to FASST rigs. Norm
