I built about 25 Uproars from scratch (5 at a time). The nose section of that design doesn't allow a ton of room for the fuel tank and the throttle connection. My version of the Uproar kit was much easier to buil than the original by planning out things better.

The recomendations made in this thread are good solutions. Let me add a couple of generic suggestions.

1) Always use a piece of nyrod between the engine servo and the throttle arm. The vibration transmitted back to the servo via a wire will wipe out the pot quickly.

2) Whenever using an EZ connector clamping onto a piece of music wire, anneal the steel rod so the screw will make a distinct impression into the steel. (Using rock hard music wire and an EZ connector will fail in time; soften the wire).

3) Always try to avoid using an EZ connector on any control surface linkage. You will regret it sooner or later.
