Per the Rotax manual....Max (120F Ambient) Min (-13F Oil Temp)...start or operate. I only know because our ambient can get near the 120 on those rare occasions. Pete |
I've flown the -12 at -7f, but that is after preheating the engine and oil to 40F. I preheat below 30f. There is plenty of warm air from the radiator, oil cooler, exhaust system to keep inside the cowel area warm. Remember, the air intake is on the back of the engine so it is getting "warm" air.

Thanks. That helps a lot. I am just finishing the Service Bulletin and doing a condition inspection at the same time. We are including a number of mods at the same time. Moeller fuel gauge, heater baffle, oil cooler moved forward, AOA, vernier throttle, and baggage compartment bulkhead mod.

CURRENT REPORT - -
Just got home from flying. Shoveled a foot of crusty snow away from the door. The airport does good, but can't get closer than a foot or two. Was ( -6C ) on the surface, and ( -10C ) at 3500'. Brought the CHT's up to 210 degrees with my Heater Damper Door. Was very confortable. TOTAL overcast, so only the heater was warming things. Could see for miles, but no sun !

I use the - -
Reiff pre-heat ( about $225 I think ), and it works great. I keep it plugged in all the time, and cover the nose with a packing blanket. If I turn on the display, the ENTIRE engine is 90 - 95 degrees. No warm up time required. Just taxi and go.

The Reiff rules! I recently started using the Pilot Portraits Cellphone switcher. I call the PP switcher a few hours before I fly and it all works great. Saves a lot of fuel on warm up.

I use the Geiger Pre heater. ;)
