Did you read the part where I said that it ran better with the low end screw on the ground?

It doesn't sound like any Swiss Clock I've ever seen.

The idle was very poor, but is now fixed.

I'm running an APC 10x3 prop. I don't recall the plug type, and it may be very well the A3 or #8 that it came with. The fuel I now have is a mix of left over fuel from last year. I'd guess it's about 13% nitro. It's about 60% Wildcat 20% nitro and maybe 40% Cool Power 10% nitro. The lube is probably about 18% Klotz. The plane is a 2 pound 2 ounce 3D plane (Extreme Flight RC Mini 3D). The tank is 4 ounces, I think, and mounted quite poorly. The plane uses a power pod with the tank, throttle servo, and engine all on one tray. The tank is held in with a bead of silicon, and never actually touches the tray, only the silicon does. The tank stopper is perhaps 1.5 to 2 inches from the engine backplate. The fuel line is about 6 inches long (with a small loop to aid in fueling) and the pressure line is about 4 inches long. The tray then hard mounts to the plane. I get some vibration at full power and the occasional bubbles in the fuel line. No bubbles except at full power.


With the drill, I now have the screw visable in the airbleed hole and a fair idle. Before, like I said, I backed out the screw so much that vibration made it fall out. It ran better that way, and then I was prompted to go ahead and drill out the hole pretty big.

It starts good, runs hard, and idles OK, but it's no Swiss Clock. Maybe I just got a bad one...
