One more thing that I discovered yesterday trying to make that 30 all day.
My elevator servo stopped working in flight, and I managed to 'land' it three times using flaps to loop it down to flat tall grass landings and once to a soft dirt dork. That Supra is one tough airframe. But in all that, something really important and valuable came out of those 'crashes'. When I did tests using all the ideas guys had used to adapt 2.4 to carbon nose cone fuses, I found that the simplest and 'best' was Don Barker's Sputnik install. The 4 extended whisker routed out behind the nose cone lip at 10-2-4-8 o'clock around its circumference. I tried to make it 'not' work, and tried to improve on it using the advice of -2.4 Techs- and using special 2.4 extension antenna wires. In the end, Don's was as good as it gets...and again simple. The Flight Log data was repeated time after time..and all good. But about a month or so back I flew at a contest in Orlando...calm air, warm temps, 8min tasks.... should have been a no brainier but for some reason my Supra was not 'flying'. The best I could do was 3 1/2min out of 4 rounds! It just wasn't listening..the funny thing was that the Flight log didn't show one Hold...lots of fades but no holds but I was sure that I was not in control of the model a lot of the time. (never suspecting a dead spot on my elevator motor commutator). I sent a note to the Horizon guys, asking if they could figure out what was wrong with my 'radio'? Of course there as nothing wrong with my radio and that was confirmed by the Flight Log's numbers. I switched to a Pike Giant (F3B/Slope Racer) that I love for Thermal Comps because its so challenging, and the next three rounds where all with in 2 seconds of perfect..one 75 and two 100 landings....versus almost cutting me and my timer in half with two of the previous 4 flights. The Barker install puts the two RXs on top of my elevator and rudder servos which lay on their sides in my fuse. After that I flew the Supra a lot and didn't seem to have that kind of lack of control again but was suddenly seeing numbers every flight of 999! and HOLDs too. I'd contacted Don he confirmed it was crazy that the numbers had changed that much. Something was weird...and it wasn't like the RX's...or their antenna. Yesterday when I my elevator stopped moving, and found that it would stop at a specific point as if it were unplugged..intermittently...and after the third crash, I switched the rudder servo with the elevator servo...I was determined to get a 30...figuring I could get away with a locked rudder (it would stop only about 1/4" off center, but would move if I cycled the stick). Of course I didn't factor in that it might also be upping the current drain on the system....and that's the point where all this is leading to... The 999 readings I was getting were only on the main RX antennas! The remote stayed consistent...and the main was perched on top that injured servo! When I switched servos, the main now perched on a healthy servo..the numbers from those flights were back to normal with no holds! So I am thinking that the servo amp/motor was likely radiating, causing interference to the RX perched on top of it...or if not that the current spikes possibly. A lot to learn about this 2.4 stuff.
