HSUKARIA,
Some fellows at field said same as you, they told me to replace extentions and even the on/off switch that is there since I first wired the plane.
IŽll follow your advice.
What is weird, is that the problem only occours when engine is over 1/2 thottle.
What if I conect an 3S lipo to the SPC port?
would it send more power to receiver/servos and overcome the interference?
Thank you.
Mauricio
