After the engine, (tank wrapped in 1/2" foam) fuel lines are in place I like to install the throttle servo where the shortest, straightest, run of what ever type of throttle rod you are using can be attached from the servo arm to the arm on the carb. Even if this means trimming a bulkhead, or driling a hole for the throttle rod to pass through a brace ect. After all its just wood and can be massaged to accomidate the placement of most any thing in the fuse. Received my Quest from Ultra RC, and after our swap shop is over this Sat will clean the bench, take a good look at my new always take to the field flyer, and get started. There is no hurry as flying season in this part of the country is a ways off yet.
