Default Electrifly AMMO 28-45-3600 info

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!

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.
