Jonkers JS3 RES electric self-launcher operation

A very short introduction on how to operate the JS3 RES electric self-launching motorglider and how to install the battery pack. This video was taken at the 2023 Soaring Society of America (SSA) Convention in Reno, NV. This is not a complete video of all the operational characteristics of the JS3, which would require the services of a qualified motorglider transition instructor.

4400RPM is perfectly in the highest efficiency band for that motor. This is a really well designed system.
