sdt22, did you mount your .72 inverted? I'm seriously considering replacing the .46 FX with a Saito .72 as well as using a lighter engine mount. My Aresti is still balancing in the "nose-heavy" part of the recommended CG range and I'd like a little more zip. The extra power and lighter weight would add some to the knee-knocking blistering speed.

Balsageek, which engine and engine mount will you use? If you use a 46FX with the supplied (heavy) engine mount and install the battery per my notes back a few posts, it should balance in the recommended forward range without any tail weight. This makes the plane docile with great low-speed handling.

Second the "great ARF" comments.
