It's running on 30% heli fuel and the extra oil leaves a good smoke trail. Leaning it out more won't gain anything in power, it's there now. I know this because the high speed screw would turn itself in and go lean, I put a mini tie strap on the spring clip and screw to stop it. Haven't tweaked the needle in a month. The header could be a tad shorter, but I've been done with messing with it for quite a while now. If it aint broke.......... I just want to fly the snot out of it.[sm=lol.gif]

Amazingly this thing is low maintenance. When I'm done flying, I empty the tank, refill it 1/4 full with FAI fuel, start & warm it a moment and run it at WOT for 30 seconds, empty the tank, run the engine dry and spin some after-run through it. Wipe off the oil top and bottom. When I get home it goes on the charger (a fresh charge is good for 10+ flights). I inspect the linkages for slop, if there is any (about 30 flights), I clean the connected linkage with alcohol and blow it out with air. A very small amount of CA is put into the connected linkage and hit with kicker. After a moment I grab the servo arm and control horn to free it up. Presto, zero slop. I change out the glow plug every 1 1/2 gallons because performance begins to degrade. That’s it.
