I installed a new Altis4+ and new YGE 35 VLT ESC in my Explorer. Both had the firmware updated - just in case - and tested. The Altis was set for eSoaring rules, i.e. permit emergency motor restart.
Every time I tried to restart the motor nothing happened. Power down and I could fly again. I tested with a RC Multi - fine, no problem restarting the YGE VLT in flight. Correct operation was verified by a friend using the Altis with another YGE (non VLT) - that worked fine, so the Altis programming is not at fault, but nor is the YGE VLT because it works fine with the RC Multi.
For some reason it is the combination of Altis4+ and YGE VLT that does not permit restart. The combination is fine for a single launch. My radio is Graupner MC32 & MZ32, neither has ever given me problems with motor start with other gliders.
Has anyone else experienced this problem?
