500 Grams of thrust 90mm EDF with Turnigy L2210-1650
Cobbled together 90 mm fan with 250 Watt Turnigy L2210-1650 Bell Style Motor (250w) seeing if I can get decent efficiency from a small fan turning slower.
Weighs around 150 grams now.
On 14.8 Volts its pushing almost 500 Grams, not so bad thrust mapping is as follows.
100 Grams 1.9 A 27.6 Watts
156 Grams 3.0 A 42.9 Watts
197 Grams 3.9 A 55.1 Watts
257 Grams 5.5 A 76.0 Watts
296 Grams 6.7 A 90.9 Watts
340 Grams 7.9 A 105.5 Watts
432 Grams 10.7 A 138.1 Watts
492 Grams 12.5 A 155.7 Watts
The data in a spread sheet
The tests were run on two 7.4V 1300mAh Turnigy 20C Lipo's in series, I figure the motor will survive full throttle bursts on 4C and its 10 Amps short of the max, 100 Watts below its spec.
Its surprising as the same motor with a 8 X 6 prop pulled 23.3 Amps on a 3C yielding 520 Grams of thrust at 232.3 Watts.
Got this battery on its way from Hobby King Rhino 1550mAh 4S 14.8v 20C Lipoly Pack
