Went flying this afternoon, raised the altitude to 207 ft. and proceeded with forward flight, I was in normal mode. Next thing I hear the RC Pro controller say, I reached maximum altitude of 396ft. I did not have my left hand on the stick while this happened. I brought the M3 back and landed, turned it off and changed the battery. Took off again and raised the M3 to 150' and applied forward stick, once again the M3 climbed on it's own and reached maximum altitude. I noticed the M3 would auto climb at a rate of 3-5ft while going forward around 15mph. If I go slower, say 5 -7 mpg it would not climb. |
