My friend recently crashed a new raptor 30 due to an engine cut[&o]. I’m guessing this was from a too lean top end mixture as he was only in forward flight but don’t really know. Not wanting this to happen to me I started reading the tuning messages on this BB. Now I’m really in a mess. Everyone has a different idea. The temp monitor way looked good for a while but then got a good slating.
I’ve got a Shuttle Z with an Irvine 36 F1. I’m using a GV-1 governor cos I don’t want to buy a new handset and setup a 5 point throttle curve. Until now I keep the top end needle as rich as possible without any bogging on full pitch climb out, but I’m sure I’m losing power.
What’s the easiest way to tune my engine. I don’t mind losing a little power but don’t want an engine cut.
Any ideas?
Sorry for the long post

In the old days we would fly it around at full throttle in forward flight then quickly land and put some spit on the head. if it sizzled and evaporated it was too lean, if it bubbled it was good, and if it just sat there it was too rich, with the IR temp gun you are doing the same thing, above 220°F is lean, 200-220 is good, below 200 is rich....
