I realize this is a 20 years old paleo thread but was recently given one of these NIB. I am usually a BMO modeler but this ARF is nicely constructed and looks strong and light. On the off chance somebody is still alive out there who has experience with this model, would this electric motor be suitable or what would be suggested, ESC also? For sport acro flying.

Horizon Hobby Power 46 Brushless Outrunner Motor, 670Kv, 3.5mm Bullet

I am also considering staying with glow and using an O.S. 50 class four stroke or a NIB O.S. 46SF Ring. Pitts style exhaust for these are hard to come by these days so that is more why I am considering electric conversion so I do not have to cut the cowl all up. Though, really, I think I prefer glow and a Pitts exhaust if I could find one.

I saw the tip on the CG to go with 2 and 7/8 inches back on the top wing at CL. I know very little about electric motors, very new to that thinking, always flown glow engines.
