Finished my Red Avanti 80mm and hope to maiden it tomorrow. Added a little extra paint, cause I just can't leave well enough alone, and hate any white unpainted foam areas. Finished out the cockpit as well, applied 4 coats of gloss spar uretahne and added an RC Geek afterburner, just because it's way too cool.
I used an AR636 with gyro and ran into something unusual with that receiver. I've programmed over 25 of these and I thought I was somewhat of an expert in programming (but guess I'm not an expert after all). With the 636, the most critical factor is to get the receiver orientation correct and do the servo reversing in the receiver, not the transmitter, where the servo's are all set to normal. The last check I do, is to set 1 mode with very high heading gain (never ultimately use heading gain though) so I can definitively see the direction each surface is moving in for correction. This time, the ailerons were right, but the elevator and rudder were moving in the WRONG direction. I have the receiver mounted on it's side, so the correct orientation in the app is a little difficult to see in the app when it is on it's side, but I know for a fact I set it correctly, yet it gave the wrong deflection. I had to rotate it 180 degrees for it to be correct (yet it is showing the wrong receiver orientation). After programming so many of these, I almost forgot to do the heading gain check cause I was so certain everything was correct-I'll never miss that final check again. I asked HH if they have ever found a 636 that the gyro was off 180 degrees, and of course their answer was no. Maybe this explains why some complain that their 636 caused their plane to crash. Still not comfortable with my results, so I'll program 1 mode with no gains as a fail safe.
