Hi,
After two seasons with the Charger, I am getting pretty good at keeping the engine running through my maneuvers. The Charger does not have inverted systems.
At the end of last year I changed from a metal to a wood prop. I am enjoying a huge performance increase from this change. The lower weight of the wood prop however lowers the polar inertia of the crankshaft and now some of my maneuvers (flown the same as before) are occasionally starving the engine of fuel and the prop is nearly coming to a halt before fuel flow starts again the the power comes back.
I am considering replacing the carb with a Rotec Throttle body and I have a few questions.
Without any change to the non-inverted fuel system, will the throttle body help to keep the engine running during very short span/momentary <.5g flight?
If I add a small header tank for inverted flight, how long can I stay inverted without engine damage due to the lack of an inverted oil system?
BTW, someone suggested a "stand-pipe" in place of a header tank. Does anyone know what that would look like or entail?
I would like to eventually get the plane fully equipped with inverted systems, but space and $$ constraints are currently prohibiting that, so in the meantime I'll do what I can do.
Any other ideas or suggestions?
Thanks,
Glenn
