Hi guys, it was the servo but not in the way that you would think. The plastic that the servo was made of was extremely brittle and the casing has broken apart at several points including where the wires enter. This has caused one of the wires to come off of the connection on the circuit board. It must have happened over time through many impacts. The funny thing is the stock throttle servo hasn't been changed and it's still top notch. Have any of you heard of this happening before and whats a recommended servo in the 30-40 quid range. Thanks!
