[quote]OWell, my maiden went fine, the second flight, not so good. On the second flight, she was flying fine and all of a sudden, absolutely no control. She spiraled into the ground and completely destroyed the motor mount and cowl and took a chunk off the battery hatch. I called Tower as it seems that the ESC is the problem. When I retrieved it, I also noticed that the right aileron was detached from the wing. I am not sure whether it was the ESC or the aileron detaching that caused the crash.
Anyways, an expert modler friend has repaird it and actually rebuilt the motor mount and straightened out any wrinkles in the foam.
Tower wants me to send the whole plane in to be examined, but now that she is fixed I will try her again. One thing I did notice was that when I armed the motor by moving the throttle stick up waiting for the one beep and then down and waiting for the two beeps, it didn't immediately power on the motor when I moved the throttle to test. I had to move the stick up and down slightly a number of times until the motor responded. That is what makes me think it is an ESC problem.
In any case, fixed or not, I am going to order a new plane and replace the stock ESC with an E-Flight ESC on arrival so that that is taken out of the equation.
Sorry to learn about the crash, but inspired to see you meeting the challenge to learn what went wrong. In my case the receiver had it's plugs all connected backwards once before it was checked by an experienced modeler; and again when the dummy connected the plugs backwards again. He finally realized his mistake and got it right. Must have cooked something in the receiver. Anyway, I was really fortunate as reported above.
Just ordered some spare parts from Tower Hobbies just in case. Among the F6F parts is a spare cowl since this is the most likely part to be damaged given my flying style. My plan is to make it as "close to bullet proof" as possible by using a lot of carbon fiber and a structurally superior use of clear packing tape. The intention here is to make the new cowl as heavy as my current one by using extra reinforcement instead of lead for ballast. The current cowl does show a few tiny "sort of" wrinkles that can hardly be noticed, so unless/until something really bad happens the new cowl will simply be a comforting spare/conversation piece to have around. I do intend to do a lot of practice flying with the F6F until anxiety levels with my heavier, faster machines can be brought down to more "tolerable" levels.
I've been doing a lot of study lately on the web about comparisons between the dandy F6F "Cat" and the vaunted F4U Corsair. Most of the better web information is fairly harmonious with the expert engineers information reported by CORKY MEYER'S article in FIGHTERS, Summer, 2001 magazine. The conclusion was that the "Performance almost equal" between the two fighters. Two things not mentioned about why the lowly F6F, in spite of its highest kill ratio over all other WWII and excellent safety record, has tended to enjoy far less glory than it deserves may have something to do with its low cost compared to other fighters. $35,000 was cheap for what taxpayers were getting with the F6F. Web information on the F4U's cost seems to indicate that it went for something like 1/3 to twice as much as the F6F. We all know (well, us older culture studying geezers , anyway) very well how MONEY can incite all kinds excitement and/or demonization about things. There is also some question about the name it was "blessed" with. Lt. Zenji Abe, the bomber leader off the carrier "Junyo," who survived swarming F6Fs during the Marianas Turkey Shoot said: "I never see so many Grumman's!" Notice Mr. Abe did not use the not so "Divinely approved" given name "Hellcat."
Better get back to the carrier now and show those Corsairs how it is is supposed to be done.
