Plane is not done. Tied up for a while. It's winter of course.<g> My gut feeling based on my E-F Extra 300 is that it will pull just fine. I just quickly thru a bunch of stuff on the scale and it all added up to about 6lbs. THe E-F 300 was all up 6 lbs 5 ozs on a Duralite F3A 5350ma 5S pack. Plus Angel S is aerodynamically cleaner. Same Torque motor from E-F 300. It bolts right in place and has to be offset by about 5/8". The Torque specs out right around the same as our friend from Norways' Actro I believe. On the E-F 300 on a 15X8 APC it was turning around 7700 rpm, 60ish Amps, and around 1000 W plus. These readings were at temps in the 40's.
