In the manual for the UCD they showed a screwy method of hooking up the throtle, where the wire sorta doubles back on itself, changed mine to a cable run and inverted the throttle arm away from the engine mount, so the arm itself where the pushrod connects to is pointed towards the cylinder head (think that makes sense, also used a clamp to attach the push cable to the throttle arm, so there is no clevis, would take a picture however all cowled up is a mission to remove.
What prop are you looking at using, mine is swinging a 15x4W and that is awsome combo, pull out of hover no probs, only needs about 10 ft of runway to get up in the air and it goes straight up, no probs
