RE: A motor to keep an eye on
The only problem that I can see is the front of the engine is too long. Most new kits with glass cowls are designed with shorter engines. We looked at these to put into the Top Flight Giant ARF Mustang, and the engine is too long. It's over eight inches long and the model calls for the front of the cowl to be 71/2 to 73/4 inches from the fire wall. We ended up using the ZDZ 40 with the rear intake and exhaust set up. Motor screams, but puts out a lot of vibration. I guess you can not have an high compression engine and smooth running in a small package.
