Mrt pro problem

[misterj]

Lost a lot of laps last weekend not being picked up for nearly 50% at one point, wasn't aware of a problem but certainly seems I have one.

What's the chances this just playing up, could it be more likely placement ? . Was bottom down straight on the chassis just behind the servo and next to the esc.

Not going to leave it to chance and ruin racing this weekend, has anybody dealt with mrt will they check them out for you ?
