Thanks everyone! Very much appreciate the quick response. I do like the look (and price) of the Sky Raider Mach I that ChuckW recommended. Looks like a great price for a good quality ARF. I have a Rossi .40 that I have had for a long time (but is new in the box) that I would like to utilize. Using this, I don't have to swap out my OS .61 SF abc engine from my Super Sportser. Looking for a reason to use the Rossi. I'm thinking it should pull the Sky Raider just fine (I am in Denver at 6000' altitude). These 2 engines of mine are old, but new in the box that have never been used. I know the Rossi is a screamer and have the newer and modified muffler. The OS .61 SF abc at the time I purchased was what seemed to be a very good engine as well. It is in my Super Sportster 60.
