I completed repairs on the Pitts Model 12 landing gear, and programmed the AS3X (watched the videos step by step). Yesterday I took it up and it flew well, but the engine kept detonating. This problem was seen before with the PulseXT 60 with its RCGF-USA 20cc, and it was a bad sparky. It was detonating so bad it shook off the muffler despite JB Weld! I replaced the sparky on the Pitts this morning and it also fixed it. It has more power and runs smoothly. In yesterday's flight I was able to dial in the AS3X gains, and today expect a great day of flying!
I don't like these stock M4F's. They don't fit the ignitions well, and they don't function reliably. This is the second one I have had to replace due to poor consistency and detonations. The first on the PulseXT and now the Pitts.
The RCGF-USA 20cc with the M4F sparky went from this...
To this with an NGK CM-6.
The problem with my Spektrum iX12 not booting from cold and dark without unplugging the battery is back. Last time this started intermittently, and progressed to not turning on at all, and I sent it to Horizon Hobby. After waiting a month to get it back, they found nothing wrong with it... Neither did I, for about a week. The Tx will turn on the orange light steady for a few seconds, then blink 3 times and go out. Doesn't matter if I hold the on switch. Sometimes it boots the first try, usually not, and intermittently on the second try. Today it turned on the light and it stayed on, but nothing happened, and I pulled the battery after 5 min of black screen. If I pull the battery plug, it starts fine the next time.
So I reinstalled the battery switch to save wear and tear on the plug, wires and connector.
When it fails to boot, I cycle the switch and it boots.
Probably will need to send it back to Horizon this winter...
