After the crash, I did move around the wires while on the bench in the attempt to find a broken wire but to no avail. After the crash, the servos and connectors were still all tight. The battery was ejected but still connected to the esc. In my attempt to retrieve the downed plane, I completely forgot to look at the rx to see if it was flashing, while my focus was on disconnecting that lipo as fast as I could in case of fire. After I watched the lipo for a few hours for puffing, it did nothing....tuff little sucker. The setup continues to perform flawlessly on the bench with a solid light on the rx.
The first "brown out" I experienced was just after pulling out of a loop, the second in level flight with just aileron to line up for landing. I in fact reduced all the 3D throws from my FM setup, just to get a good second maiden on this new receiver so binding wouldn't occur which it had not in the previous settings. I'm going to continue to work with it on the bench till I find the culprit. I'm really hoping a broken wire will reveal itself, cause this setup is going in a Kyosho F-16 next.
Thanks everyone for trying to help locate the cause of this problem. As far as giving up completely on it, the odds are still in my favor and I have way too much invested in my Spektrum setups to just go back to FM permanently but I may leave my tried and tested FM setups alone in my gliders and just keep the 2.4 for all of my smaller aerobats.
It's a funny thing,when your plane leaves the ground, you put all of your faith in the components you've installed in the model. I don't believe in buying cheap brandless components from some offshore outlets for this very reason. I have been flying since the mid 90's so I consider myself lucky to have only lost a lousy $20 airframe at this point but this kind of thing rocks the foundation this hobby is based on...TOTAL CONTROL. Until you've experienced total loss of it, its easy to see how we take it for granted that our planes will make it safely back on earth in spite of numerous variables working against us. Like they say, think of your r/c aircrafts as being disposable.
Dead sticking this 3d model into the ground has just lost a little of that faith, but the most damaging thing to my psyche is that I cannot seem to replicate the brownout on the bench using the same exactly setup and approximate placement, even while loading up the prop in a stationary fashion at full throttle.
