hi gents,
just to help others that might not find it in a manual or elsewhere:
if you take the 109 for a flight, land and shut it down, than try to start it again, the engine might not catch.
to get it running again, disable all ciruit breakers for position light, radios, etc. that are not needed for engine start.
after doing so you can restart the engine without problems.
(at least thats working for me)
have fun with this little bird :)
regards,
RR
