Hi Pablo,

have a look on the Hacker webpage (which has an English version )

I checked the data with a motor calculation program and it looks like that you would prefer 3 s-Lipos. Two typical data sets at 10,5 Volts assumed supply:

13" x 6.5" Aeronaut prop, 32 Amps, 338 Watt
13" x 7" dto., 40 Amps, 427 Watt

Ideas of required power for glider use differ (don`t they SteveR )) ) but experience tells that 100 W per Kilogramm (approx. 2.2 lbs) yield a safe climb at about 3-4 m/sec, whereas approx. 140 W/kg gives you 6+ m/sec.

Take your choice
