70cc twin V2
Hitec also tried to pass the buck, in the end the IBEC's were not the A9 culprit. I have run the A9 since it came out and with Tech Aero IBEC's with no issues at all. That said I had a friend loose 2 100cc planes with the A9 and I was present for one of them. Neither plane had an ibec in it. The A9 issue was solved with a firmware update, but it is strange that not all A9's had the issue.
