Just to add to the mix of motor / gearbox combinations.

I use 2 motor / gearbox combinations in e-Supra-ish toys (home built std Supra wing and a wing with 3.6m span and a slightly thicker section based on the AG40 series I made up about 3 years ago - flying weight on both <1900g).

The combinations are Mega 16/20/2 with Kontronic KPG25 5.2:1 and a 16/25/2 with KPG25 4.2:1 gearbox. I use 17x9 - 17X11 props and Jeti 70A switched BEC controllers with TP 1300 3s 65c batteries.

Happy with the performance in F5J format. Can climb to 200m in 20secs if need be, but clearly better not too.

YMMV
