Well, the WEST 50 T1 with the Throtle Pipe for this plane is a lightweight powerful combination.
What counts is the linear feel on the power you get, not the absolute Higher RPM.
This engine is ported for torque has a true ABN construction, runs smooth throuout the throtle range without hesitations, breaks-in on the plane, and it has the looks

Very pleased with the whole package (Plane -engine-pipe).
Just make shure you get the correct Pipe for this Engine-Plane. It is a custom special made one.
