New YS 63 numbers.

I now have about 50 OZ of Cool Power 30% Heli fuel through my YS 63, on my test stand. I have tried an APC 14x4W, 13x3W,and J-Zinger 14x4.
I had to turn the regulator screw in (clockwise looking from bottom) about 1 1/2 turns to get the midrange cleaned up. Now great idle, transition, and top end.

These RPM readings are not peak, but are backed off for flying.
APC 14x4W = 10,200 rpm. Lifted 8 lbs, 4 oz on my test setup.
APC 13x4W = 11,600 rpm. Lifted 8 lbs, 12 oz.

J-Zinger 14x4 = 9900 rpm. Lifted 8 lbs.

I like the APC 13x4. Throttle response is excellent, and spin-up is quick. The APC 14x4W loads the engine more, and slows the spin-up.

I have 6 cases of Magnum 30% YS DZ fuel on order. $17.50 per gallon delivered to my door.

(I also have a 1.40 DZ
