Giant 45% Pitts Challenger with 220cc motor crashes down to meet its rc pilot below! RC Plane 

but not smart not checking the CG !

Yes I had too one the boys said the was no spring in the plug cap fitted the spring and all was good. He is a good pilot to save his plane like.

The only less than perfect variable is flying a Spectrum radio, seen too many unexplained crashes with them. When you cut back on throttle you regained some control. RF interference. A guy said he had the same problem with his Corsair, what was his radio. The answer is not more satellites.

Muito bom!!

I have seen this happen many time and with different brands of transmitter. Found the problem to be in a loose spark cap. The spring clam on the spark cap heats up and becomes loose. One fix is to remove the spring clamp use a hose clamp. Tighten it on the spark cap problem is gone. I have helped several people with this same problem. Most of the time it only affects one control surface. Test by starting engine monitor all control surfaces. Slowly advance throttle slowly check control, problem occurs at half throttle or greater. Hope this helps.

You problem started with the choice of Radio gear1

I believe is not the first our the second but the third one ( you don’t know to ready. Because if you do it you will see the problem is the radio . Thank you

He certainly knows how to fly! Precheckes could be better though! That's also piloting. After all he saved the plane which was maybe one percent doable! Good job!

@@rodneisenhoreti8161 oh I didn’t realize that.. good save then! Beautiful plane!

I really like your colors and graphics on your model. Care to share how you acquired them?
