Karl,
I use the Skydrive system on my 912-S and leave it on all the time. We
haven't had any problems here in the USA mid south at 95 + degrees all
summer. I have very long taxies at MQY. When the motors hot and I need
to re-start, a little throttle as soon as you crank it and it takes off
every time.
Just my two cents,
Regards,
Jeff
A258 Gold Rush 33.5 hrs of flying off the 40 and all the bugs seem to
be gone ;)
