Thanks for the insight. I am still kind of up in the air on which engine to use. The RCV 90 was a gift. It is still new in the box. I am concidering putting it up on ebay to see if I can then replace it with a new OS61FX. I have had one of these before and loved it. I am concerned about the weight factor. Also, my club has a grass field, and not the smoothist one I'm sure. With a large prop on the RCV 90, ground handling will be an issue.
I love the old plans. There is something of a bonding with the plane when I build from scratch(plans) I have had one arf and when it crashed I really didn't seem to care. When I lost a contender I had built from a kit with a few mods I made I am still in morning for it's loss. (LOL).

Tks
