I have been flying electric birds for a couple of years and recently purchased a t-rex 600 nitro pro with a O.S. .50 hyper. I would like to know if there are any good websites for tuning in different weather, using different fuels, etc. I have been running Cool Power 20% but getting ready to make the switch to Wildcat Youngblood 30%. What temp should I be running this engine at? Sorry for all the questions but like I said I am knew to this nitro thing again and don't want to destroy an engine due to lack of knowledge. Thanks.

First off, I would recommend Cool Power 30 over the Wildcat 30. What some local pilots and I have noticed is that Wildcat 30 seems to run unusually hot, even at very rich needle settings. Personally, I think Cool Power runs better, but thats just me.

Onto tuning, there is no real "standard" for needle settings. A good starting point is 2 whole turns out on the main needle, and then go from there. A good way to get close is to feel the backplate of the engine after it is warmed up. If you can hold your finger on it comfortably for four seconds, then you are in the safe zone.

Yep - I had the same issue.

Saturday morning I flew my helicopter in my pajamas
How it got in my pajamas I'll never know
