Hi. Is the engine below too large for a SIG 64 Four star plane? I already purchased the engine and awaiting shipment and now I'm starting to wonder if It will be too large. This is my third plane and I still consider myself below average pilot time.

GT17 17cc Two-Stroke Engine from NGH - NGH-GT17

I built a couple of 4*60s from kits and put a Magnum 1.20 4S on them and they worked great. Of course I hacked the heck out of the kit, flatening the wings, building up the ailerons, elevator and rudders larger. The 17cc engine weighs about 1.9 pounds, which is a little heavier than the 1.20 glow. The 17cc gas might be a little less power than the 1.20 glow, but should still overpower your plane satisfactorily. Sorry someone didn't respond to your post sooner. Let us know how it workded out for you. I am currently looking at putting a 17cc NGH on an Excapade .60 ARF. My other options are a 20cc DLE or OS .65AX depending on balance issures.
