Sooo...Jester flew again today! buuuut I also fried ANOTHER ESC! >_<
I successfully flew two batteries, and on the second one I was flying with another jet, and we were chasing each other around the sky in a sort-of mock dogfight...and instead of throttling up and down as I usually do, I just left it at full throttle as a tore around the sky. It flew GREAT ... Until about 3 minutes into the flight; I was making another low pass and the motor just DIED. So I glided it in (again), and assessed the damage. No damage to the airframe, and no magic-smoke or smell, but the ESC shrink wrap was completely melted off. BTW, this was definitely not an over-current problem. A static test on the ground showed I was pulling 80A, and I was using a 125A RedBrick ESC. It definitely just overheated.
Conclusion: Vent holes are needed in the nose compartment. I worked out a way for there to be a vent exit at the tip of the inlet-bifurcation, but I didn't provide for any vent INlet. So I'll be adding two NACA inlets on the sides of the nose, as well as the cutout for the vent exit on the bifurcation. Look for those on the next release of the plans.
I've also got something in the works for this A-4 and my currently-in-development F-20 ... I haven't made a thread for that one, but I will... stay tuned.
