Successful Top-Flite AT-6 Conversion...CRASH!
Well, I finally got my old Top-Flite AT-6 converted over to e-power. I replaced the OS .61FX with an AXI 4130/16 on 20 GP 3300's.
I lined-up on the runway in to the wind and feed her some power, the AXI was making GREAT power and I took off and was climbing strongly. I was in the process on trimming the elevator and started making my first turn...I lost complete radio contact! The At-6 spun in and is totalled!!!! So much for what seemed at successful conversion. I don't know what casued the lose of radio reception...everything works on the ground. I range checked with the motor running, all was fine. I am in process of stripping the gear out of the AT-6 and I will send the RX to Horizon for a check-up. What should I put the AXI 4130/16 in next??? Thanks Brian |

Brian,
Sorry to hear that your AT-6 was totalled. What an incredible range of emotions in a single flight! Did your AT-6 have retracts? The only thing that comes to mind was a similar incident by another RCU member that had his retract servo jam and take out the UBEC that supplied power to the receiver and servos. |

That sounds like my first P-51 crash. To a "T". Greg, I am starting another thread on the second "stang".
Please give me your input........ Longarm |

Sorry for not replying sooner...
I think I figured out the problem. I think I experienced a high-speed tip stall. The AT-6 was heavy (too heavy) and I had came back on the throttle some and the AOA was very high. I was using a Castle Creations Phoenix-60, UBEC on 20 GP3300 cells. The AT-6 had Robart air retracts, but the gear was locked down, no air tank, air valve or servo installed. I tried to cut corners and didn't replace the the standard servos or wheels, that would have saved about 10oz, plus the 50+ oz of batteries, I think I was too heavy. Can't decide on what to do next....ideas? Brian |
