The pic just happen to have a ez link...I would NOT use that on a gas motor....

I agree...ball link is the best. However I have used nylon clevises as well.

I think I'm going to solder my hole shut on the butterfly as well. Just for the sake of more control over airflow to the motor...and to be able to kill the motor with throttle.

One of the big things with the butterfly throttle is that it's not as LINEAR as the barrel carbs on glow engines...
Not as much change above half throttle.....it's like half throttle on the Tx is more like 3/4. A little mixing on my radio may help that...

High Flights!
