RE: Hobby Lobby Super Cub Speed 400
You could get power equivalent to a 400 with a 40g /120W motor, but you need some nose weight, so I'd choose a 70g motor with 200W+ capability and a 25A-30A ESC [that will still be lighter than the 400 and Mini-Olympus]. A Suppo A2217-8T (~1175Kv) [or the BP equivalent] would be happy with a 9x5 GWS HD (180W, 35oz thrust), or a 10x6 GWS HD (222W, 40oz thrust).. those would certainly pull it off the water... but if you don't want to use a gentle thumb on the left stick, fit an 8x4 GWS HD.
