After it's broken in, how long will it run on 1 ounce of say 20% nitro fuel ? 

100 psi? Bloated? Are you pulling out legs? I would have thought that would blow the endcaps off the tank!

I have a 1-1/4 oz tank, 20% fuel APC 6-2 and 52' handle to thrust line and I run out of fuel in the overhead 8. It is running a little rich but if I lean it down any more it's just too fast. Cox TD venturi (.116") should I go smaller?

Update: I just found a way to make the tank bigger using 100 psi compressed air LOL. Tank was 34cc now bloated tank is 37cc. Just have to be careful not to pinch it back down. Also, the manual says these things run ok on 15% so I've got some flying to do.

Hi Motor Man, why are you using a 6"x2" prop? can the 1.0cc Norvell pull a 7"x4" prop?  If the Norvell can swing

a 7"x4" prop, you'd get less RPMs, hopefully usable thrust, slower, more manageable lap times  and far better

fuel economy. That is a small displacement class "A" engine, not a Half-A engine.   This is  simply a suggestion;

because I'm not familiar with 1.0cc glow engines. I am very familiar with 1.0cc diesel engines; that make very usable

power with 7"x5" and 7"x6" props for control line flying. Best of luck.    Tony G 

Manual says 6-3 is max prop and the engine peaks out at 22,000. I found a nice prop that i will try tomorrow a REV UP 6-3 which pitches out to 2.5 and has less load around the hub area than the APC 6-2 and has more blade area. It's a pristine copy that would make a great pattern for a mold but it's wood so, hope I don't break it.

     If you know what you want in a prop and you can mold your own props, carve your plug plug. Hell, that ain't half as hard as everything else. You could stack up 4 or 5 Popsicle sticks and carve that into a plug. What's holding you back? Just make sure you carve something that the engine is known to like and don't try to make the engine run like LA.46 because it ain't.
  Type at you later,
