>>>Can someone please explain how the engine is started when it's inverted, and how do you adjust the idle once you have it running?


The same way as usual, connect the glowplug (most connectors work just as good upside down) and flip the prop it with a stick (I hate e-starters).

Just be carefull not to "drown" the engine (is that an English expression??) I mean make sure you don't get to much fuel in it since it will accumulate in the cylinder, on top of the glowplug, and it cant escape.

To much fuel could cause the glowplug to cool down, making it harder to start. Even more fuel in the cilinder in combination with an electric starter can cause serious damage to your engine.

If I really really really need the starter (almost never) , I put the plane on a wingtip (you might need a helper) so the exhaust points down, allowing fuel to leave the engine. This orientation also seems the best way to start a hot engine.


Don't worry to much about it, once the engine runs, it runs just as good inverted as it does in the normal orientation.

Hope this helps
