Hey Bubbagates,
I for one agree with you. I would also prefer to take whatever time needed to trim out my planes to get them flying straight and true, but I get the same grief from other pilots you do. What drives me crazy is that the more you get into making small changes, the more the changes will affect things you have already corrected
I've actually converted a few. I met one guy at a club I just joined. We both had the exact same plane with the exact same setup minus the brand of servos, he flew mine and turned right around and changed engine thrst at the field. He then went home and shaved the wing saddle, etc...
I've had others fly my stuff and comment on how nice they fly.
It's a bit of work, but well worth it in the end and it can also prolong the life of the plane because you end up with one that is very predictable
Any engine can be run inverted, it's a matter of tuning. Most problems with inverted engine can be traced to the low needle being too rich
It's harder to tune one that is inverted because even a tun of 1/8th inch can make a huge difference. I tried something when I flew glow and it worked for me. Run a fuel that has a higher oil content. This will allow you to lean it a bit more and still get oil into the engine. Again you still have to be careful of getting it to lean
