Just ordered me a YS 63 for my Kyosho Flip 3D. I will be using an apc 14x4W prop. My question is on what fuel to use. I have been using Cool Power pro pattern 20/20 for everything else glow. Should this be sufficient for the 63? I think the fuel is about the same as powermaster 20/20

Should work just fine, but sometime try some CP 30 Heli for a real treat.

I appreciate the info, will the 30% not shorten the life of the motor?

If you run it too lean with ANY fuel it will shorten the life span of the engine.

Good deal, ended up just getting cool power 30%, should I break it in on the ground, or just set the needles a little rich and fly it?

Run a couple of tanks on the ground and go fly it.

Have Fun!

Ran the motor for the first time yesterday on the 30%, started first time and ran like a champ, getting 10300 rich with the 14x4W which should be plenty of power since the plane weighs 5lbs 5oz

Cool deal!!

Have Fun!
