RE: Electric Motor Size
It's not that simple and I could write a novel explaining why. The easy way to find a brushless combo that will work, is do a search for your plane here on RCU as I'm sure somebody has flown or is flying that plane with a brushless motor. Then all you need to do is copy their set up.
If for some reason that does not work for you we will need a LOT more information to put you into right motor, battery, prop, ESC and maybe gearbox combo. In fact if you do need to go that far this is a post much better suited to the Electric forum.

(835mm) , flying weight 600g , wing area 19sq dm. Instructions only call out to use a 400 motor! I'm hoping someone out there can tell me what combo to use for this bird. Thanks Basslakeflyer

RE: Electric Motor Size
I'd probably use an EFlite 450 or 480 brushless outrunner with a 25 to 35 AMP EFlite Electronic Speed Control. The battery would be a 3cell Lithium Polymer 25C discharge over 2000 MAH. The prop would depend on the instructions for the chosen motor. I've had great success with the EFlite motors and also with AXi's. I can't find my Hobby Lobby catalog at the moment so the motor number of the AXi motor is forgotten. I also like Castle Creations speed controls.
