Status: offline 		I am trying to find out what that motor will lift. I can't find any info on how heavy of a plane it will take and I am new to electrics. I have a few, but just use what the kits call for. I have 2 gliders I want to put power on. The first is an old windrifter 118 inch wing and won't take much. Had an old graupner in it but fried it. The other is a 140 inch flat wing glider with glass fuse and foam wing. Its heavy though.

Any idea on the best motors to use? Thanks for the help!

Status: offline 		Being pedantic, that motor can't lift anything.. but with the prop you fit to it, it can be made to lift a decent amount. Realistically that is a 400W-450W motor so, depending on how much flight speed you need, if you gear it correctly, (say 5.5:1) you should be able to get it to spin about a 13" prop. For large gliders like yours, my feeling is you may need a heavier motor than 133g.... but that's beyond my area of expertise.
