I am having trouble trying to hookup to the throttle on a new Evo 35....the throttle on the engine is shaped like a half moon with several holes along the edge, it is also very close to the carb body, so not enough room for a long screw....its hard to believe but I can't find directions with pics for the Evo or a DA or DL....any help please...Thanks WC

One option is to remove the arm and install a different one.

If the shaft has a screw holding the half moon plate it is 4-40. Remove the screw and plate and replace with a Hitec blue servo arm then replace the screw with a star washer. Works great. Credit goes to Bob Pastorello for this idea.

Make an extension that screws to the existing moon shaped plate.
Or make something [link=http://www.prme.nl/forum/viewtopic.php?t=97]along these lines.[/link]
