Re: Latest and greatest timing and deck height?
Ahhhhhhhhhhhh, yes, the fit of the piston in the cylinder. I do remember reading about that in previous posts in this thread. Thanks for copying in your answer to me. First then, my assumptions of typical deck height without shims being .188" and typical head depth of .185" are correct leading to my...

Re: Latest and greatest timing and deck height?
It's setup at no liner shim, 17 under the head. The dry fit is 230 down. Hey Ray. I hate to be an idiot, but I've crunched the hell out of those numbers and I can't figure it out. I must be totally missing something. If the "230 down" refers to the deck height without shims, then, as best as I can ...

Re: Latest and greatest timing and deck height?
Cool tip, instead of using a new plug to judge the motor use 0000 steel wool or, mothers mag polish to remove the carbon. Clean well and use again. This way your apples to apples in your evaluation. Looks like your well on your way to competeing on the next level. That's it Ray? A helpful tip and a...

Re: Latest and greatest timing and deck height?
Continued from previous post... So this is my final (3rd) flight of the day last Sunday. Same plug as the previous flight (2nd flight on plug overall). The plug may be ever-so-slightly darker, but the oil deposited on the plane was pretty clear. If it was lean I would think the plug would have been ...

I’ve just gotten into Q40 this year and I know I have a LOT to learn. It's very humbling to have been in the RC hobby for about ...

Re: Painting on Monokote - New Option
My concern about painting over MonoKote - however well the paint adheres - would be how does it react to the heat of an iron with a cover sock when you want to go over it later to remove any wrinkles that typically appear from time-to-time? I'd be afraid the paint would smudge. :cry: Sounds like tha...
