ALES / F5J Glider motor selection chart

ALES is for Altitude-Limited Electric Soaring

To help you choose the right power setup for your preferred motor glider for ALES/F5J competition, we've put together this table with the best setups we've tested on different airframes.
Since ALES competition does not require that ultimate power setup, but the lightest yet powerful enough system that will bring your glider to 200m in about 20 sec. this leaves a 10 sec safety window.
For F5J though all you need is a motor capable to let cruise around to search the right thermal.
