Queen Bee

I wanted something different so I built the Queen Bee. Now I need to get the engine running and test fly. I was thinking that 20' of spider line should be good for the first flight. I thought I had some of the .020 props laying around, but could not find them. I did get some APC 4.5X2 for now and will try them. The APC looks big on the engine.

Robert,
I notice that you have the needle pointing inward. Did you do anything to the plumbing in the engine to prevent fuel from spilling out the fill tubes? How about the fuel pickup tube?
If I remember correctly, Larry Scarinzi left his needle and cylinder pointing up. Of course, that was back when the Pee Wee was a newly released engine.

I think it was in the original writeup that had this configuration for the engine and recommended capping one of the vents with a small piece plugged fuel line. The plug is not shown in the photo. If the needle was in the upright position then it would be very difficult to adjust the needle with the engine running, as it is it is a little hard to hold and start the motor. The internal pluming was modified some to put the pickup in the right place. But this is all theory for now and may need to be changed based on how it flies.
There is a monoplane for the .020 call the wee one that has very similar construction that would be fun to build but less of a hassle when it comes to the engine and tuning.
If the pee wee 020 does not work I always have a couple of TDs laying around unused.

Plugging the lower vent and put a piece of tubing on the upper one to raise the opening above the tank should work. Or bring them both above the top of the tank and you won't have to unplug the lower one to vent tank while fueling.
I think COX used to do someting similar on the free flight helicopters that had the engine spinning with the rotor- but can't remember for sure.

I still have one QB kit left, if anyone's interested. Mine flies very well with an .010 on 20' lines; a good .020 will pull 27' lines no problem. If you don't limit the elevator travel pretty severely, it'll do a Bi-slob thing. Lotsa fun, loops, eights, etc.
