OK I'm trying to sort out an issue with my radio KO ex 10/spektrum mod and rec. I noticed a few weeks ago at the track, some occasional what I'll call lagging, a slow responce to radio input, and loose its trim. This would happen maybe 2 times in a qualifier. I checked battery voltage, connections, antenna lead, and found nothing. The next 2 weekends the symptom gets worse, now it will randomally turn the steering servo about 1/2 way and return to normal position, as I was carrying the buggy to the pit wall, I saw it do this, and on the back straight, at full throttle, it turned straght into the haybales and into another buggy, I've rebinded, and no change. I just got a new spektrum mod and rec. fresh battery, bind, and as the buggy is sitting on the box, you can heard the throttle servo chatter, some call this the servo finding home position. I have 2 Hitec 7955tg's in the buggy, if you put your hand on the servo horn, you can feel the horn move very little, maybe 1 mm. I've change out throttle servo, and the same, even when the buggy is on the ground, you can hear the servo, I'm not sure where to go from here, anybody have any ideas?
