An update on the demise of the RC CM. I scavanged the servos out of the model and was using one of them in another project to test the channel assignment on the receiver. When I plugged it in it seemed to work fine, but then started moving full motion from end to end and then stalled with the horn way over. If this happened while the CM was flying, it would have caused the spiral dive that I couldn't recover from.

So main suspect in the crash is now the bad servo and not a loss of signal or other radio glitch.

Kevin,

What brand of servo? Oh... by the way, nice airshow! That really was a nice looking model.

Now that I know it CAN be done, I do have another kit and am thinking of ways to improve for version 2.0. I had some plans to try and have it done for NARAM, but I don't think that's going to happen. This seems like a fall sort of project.

Very clean setup! What size carbon rod did you use for the pushrods?

One small suggestion for v2.0. Consider using Dymond D47 servos. They are the best sub-5gram servo available and would only add 2-3 grams to your model. (I can add that much with a bad paint job. )

Looking forward to seeing v2.0 fly. Good luck.

Regards,

FlyBack
