Sounds like the TX may be set-up for low throttle when the link is lost (RFI), and somehow there's enough interference to make that happen. Are you flying in a congested, dirty with RFI environment and is your TX set-up that way?

Hi Guys.
I am a F3A belgian team member and I prepare the WC.
I got a problem with my OS160 Fi.
The engine throttle back to idle (like for a low voltage alarm commanded by the receiver) on a non regular basis but usually once per flight and almost each time I put full throttle for 5" or more. [:@]
I am using a 2lipos receiver battery with a Duralite 6V regulator PPD-54060 . I got the problem with 2 different regulators and 2 reiceivers Futaba 149DP. I suspect the EC-2 (Electronic control unit) but I have no spare for test. [

Anybody got that problem before?
Thank you.
Happy flying,
Benoit
