what prop size would be recommended for a 26 oz. sailplane? i'm using a gunther outrunner brushless (it makes about 30oz of thrust drawing about 14amps, according to the manufacturer)with 3s 1700 lipo. it's a combination thermal/ dynamic soaring plane. it's the mouton 1600 ep from giant scale planes. 63" wingspan. modified rg 15 airfoil.

thanx,

I would start with a 9/6 folder, and measure your amps, and go up or down from there.
