Designed to be a direct swap out for Park .25 size motors. This brushless outrunner will provide more power and longer run times with its high efficiency.
A quality motor, built specifically for planes designed to fly with .25 glow engines.
Battery: 3~4 Cell /11.1~14.8V
Max current: 44A
No load current: 11.1V/1.3A
Internal resistance: 0.05 ohm
Diameter of shaft: 5mm
14.8v - 13X4.7 Prop - 12A - 640g Thrust
Bench Test G25 / 610 kv:
Lipo Compact 3S 3300,
Aeronaut Foldingprop 14 x 8, 12,4 V, 282 W, 23 A.
Aeronaut Foldingprop 15 x 10, 12,3 V, 461 W, 39 A.
This motor is awesome! Looks to be well built, weight was 182g, I measured 630kv. Comes with prop adaptor but no bullet connectors.
I tested with YEP 45A esc and 6s 1000mAh 40C/80C Kypom packs.
12x6 apc-e prop settled at 2.5kg thrust, 19V, 32A. Short bursts were 3kg thrust and none of the parts got hot. 13x6.5 was a bit too much for my packs but worked well in short bursts, peaks of 3.3kg thrust and 1250W. Better performance could be gained from larger batteries but didn't have any to test.
Have tested it with 11x8 3-blade Master Airscrew at 4S
The motor became little bit warm.
KV calculated with Motocalc is 615 and Ri 0,075ohms
will test it with bigger prop at 5S
