Hello guys,

My friend flys a Feibao Hawk with 12Z with Spektrum module and Rx + 2 sattelites.

This setup has been flying well for some time and today he had his first problem. He wanted to alter the CG so he moved the ECU pack to the back for the second flight (first was good), which was about 2-3" from the second satelite, and took off. in flight he had lost and regained radio signal but managed to land the model with just a cracked LG mounts.

Anyway - we would like your opinions about what could cause this, could it be the ECU pack close to the 2nd sattelite ?

BTW for power he is using TWO Fromeco 2600 Li-ion packs with a Duralite Gemini providing twin regulated 6V outputs to the Rx, so i dont see a power issue.

He will send me pics of the setup he used for the problem flight soon, and ill upload them.

Your opinions are welcome.
thanks !
