Another test video about Omphobby M4
This is the second video about the M4. This time the flight is a sport flight with low RPMs. In the first part of the video the RPM is 2400, later on Jonas Wackershauser, the designer of this helicopter is switching the RPM to 1800.
IMPORTANT NOTE: This video was taken with a smaller capacity battery, a less efficient motor and tail drive, as well as a heli that is approximately 75g heavier than the production model will be. Achievable flight time at these RPMs will be, for the final model, 5 minutes for sport flying at 2400RPM and up to 10 minutes for low RPM at 1800RPM.
