Graupner 15x8 3 blade

Did a runup on a Graupner 15X8 3 blade prop and amped out at 62 amps/about 1400 watts on wattmeter. Slight amount of vibration over the 16X8 APC two brade. When I get time will try and see if I can get a better balance done. 6S 4000mah was only charged to about 24.8 volts so was trying to run a simulated partialy used flight pack ( 78% charged)... Pretty wide blades on the graupner so was surprized the current only at 62 amps full out. No rpm readings as done indoors and lighting would not have given correct rpm anyways.

Good thrust but definitely not as efficient as the APC 16x8 two blade which only draws about 52 amps full out with similiar thrust
