I flew my Smoothie powered my an OS 46 nitro engine today and it did quite well. I guess I still may have a little nostalgic room in my heart to salvage a few of my nitro burners for old time sake. I think I will keep my Cardinal, my Pathfinder and my Smoothie all powered by OS 46 nito engines. If they are nice, I may take them out with the electric machines once in awhile for a little exescise.
Best wishes and good safe flying.
