I tried the auto restart, it works ok but you better have some altitude. I think this is just a stepping stone for jetcat, the real benefit will be in the spark ignition motors. There is now a P220 with spark ignition , ECU is on the front board, starter is contact drive instead of magnetic because you need fast spool up. This stuff really geared toward UAVs but its cool to think we have auto relight , just like full scale. I believe you can have the auto restart as automatic , or pilot controlled on the p130.
