I have a curious problem with my TC Spec..

When I run full throttle with no load, the motor goes full out for a short while before I can hear a "blip" in the motor's speed randomly every few seconds, as if I momentarily let off the trigger. The blue light is solid on at full throttle and never blinks, indicating full throttle position, but the orange light on the speedo blinks quickly every time this happens.

When the speedo is at rest, I can see the blue light randomly flickering once in a while.. I think this is supposedly the LiPo cutoff warning me, but it's a fully charged pack! I've tried both a LiPo and NiMH pack..

I've tried turning off the LiPo cutoff mode and it still blips while running, though just thinking of it now I haven't checked to see if the blue light still blinks while at neutral.. I'll have to check..

I've tried it with both a SP13.5 and 17.5 Duo, and two different sensor cables

Any suggestions?
