Hey Jack! Yeah, I think with those short antenna receivers you can get the plane into an orientation that blocks the signal. I never had another brown-out with that Super Cub after relocating one antenna outside the fuselage. I can't believe after that 1st launch this Plane is flying so well ;-)
It could have gone into a flat stall, I flew a piper cub that was tail heavy, it was a handful to fly, then as I was turning to bring it in it went into a flat spin stall. No input made any difference even giving it more throttle. It span down like a samara. Luckily enough there was no damage. As soon as I put more nose weight on the plane it flew very well. From what you said it sounds very similar to what happened to mine. Your plane flys lovely and so quiet. Can’t beat brushless motors.
Hi Philip! I was very lucky to get this plane back on the ground in one piece after that first launch. I had it set to the specified CG but forgot about changing the thrust line with that new motor and mount. That mistake nearly cost me the plane ;-) My CG is now approx. 12mm forward of stock. Nothing beats those brushless motors for quiet thrust and efficiency.
Those ammo boxes have many uses don't they ;-) I enjoy this one much more than the Mini P51D as the larger the Plane the more stable it is in flight. This one also has, if I'm not mistaken, a 1.35:1 Thrust-to-Weight Ratio giving it better performance. It took some work to get it to this point, it's a Tinker Plane, but I'm finally happy with it and it may just be a Keeper ;-)
ESC & motor always gives up B4 controls give up, on signal loss, bcz if esc loses continuous feed from receiver it requires reinitiating ie it won't reinitiate unless u chop throttle. U can verify this by simple experiment on your table by restarting Transmitter while plane is on with motor running... Hence, it was a TIP STALL (that feels like control loss bcz ailerons r starved of air), not control loss. The simple prevention for tip stalls is reduce max elevator deflection. making it impossible for plane to get into hi alpha configuration and subsequent tip stall. In real planes they reduce AOA on outer wing by twisting outer wing leading edge down, so that inner wing stalls first & pilot get forewarning. But on a model plane u won't notice that forewarning
I agree with the Tip Stall characteristic, and I've had a few, but in this case the plane was in level flight at cruising speed while making a shallow turn. Many of these receivers will hold the current position of all control surfaces and throttle for 1-2 seconds before zeroing out. At low altitude that's all it took for the plane to dip, catch a wingtip, and then cartwheel ;-) I check Fail-Safe on all models before 1st flight and when I power off the radio I can count 2 seconds before the motor shuts down and the control surface go to neutral. After relocating one antenna outside the fuselage I never had a problem. I did experience additional tip stalls though ;-)
From your explanation I gathered that plane was inverted after after split S, when it spiraled......It, could be a temptation to give full elevator as the plane starts coming down inverted towards ground... Nonetheless the bench test I mentioned earlier will be revealing
@@engineerahmed7248 My Bad! I thought you were referencing the Super Cub which I compared this too. Yes, it was after pulling through the split-s and on it's dive through that it started to spiral. I had performed many of those maneuvers as well as very large loops and never experienced a spiral during a dive out on this plane or any of my other planes. I wish I had the camera rolling at the time but it was just a fun flight for me. I had actually thought something had broken on the control surface it was so strange. Since I haven't experience that again performing the same maneuvers I can only surmise it was a temporary loss of radio contact but you never know. I would try to duplicate the issue but I don't want to experience that crash again ;-) Your input is always valued and I learn a lot from your input.
Your antenna theory brings up a lot of questions in my mind. Glad you got it flying well.

Its looks pretty. N nice flying.
Thank you much! I'm very happy with how it turned out. It may be a Keeper ;-) See you in the Air!
Hi! For your rudder and elevator, did u attach it to the inner most hole? I cant get the right setup for rudder and elevator.
Here's a link to my setup file which has all the info:
drive.google.com/file/d/1PRYGUdolj63_nkdUV04zmwcWF-OfSV2d/view?usp=drive_link
How would you compare this to the brushless mini mustang now? Which do you enjoy more?
(Love your battery box.)
Happy flying!
