We once got stucked in the middle of nowhere, temperatures went down to - 30°C and where still down at - 20°C in the morning when we were trying to fire it up.
We were using the same kind of stuff RobboRider was talking about (I think it was called "Auto Start Pilot"
). This in combination with the priming worked just fine.
But then the mechanic came up with the idea trying to find out what the limitations for the R44 were as far as cold weather operations is concerned.
At those times the factory told us that if we were able to fire it up we were able to fly it. "Just give it plenty of time to warm up."
Any news on that? Haven't been in a Robbie for quite a while.
