Birdbone Helium, Speed Test, 2100kv Motors (low gear)02:55

  • 0

RaceKraft 5051 tri-props on some old 2100kv Sunnysky motors.

120 yards between goalpost in 3 seconds = approximately 80 mph (129 kph).

2100kv is like low gear – very slow – better for slow but punchy maneuvers. Can’t wait to try this with some fast motors (EMAX 2600kv’s coming soon).
