Thanks. I just checked and I do have the travel direction set correctly as when I push the throttle to full up the prop will try to spin and does sometimes but it never does. It may turn a quarter of the way, but that's it.. Then the motor just stutters and nothing ever happens. I'm growing suspicious of the ESC. I soldered the motor to the ESC wires. I don't think that would be the issue. It should still spin - even if it's the wrong way.
Have a look at the build video for the new CY Mini.
The way Herc does it in that is the way I do it. Mark your cog on the wing close to the fuse then just grip the fuse above that mark and with your lipo on the horizontal fuse slide it up and down till it feels right, mark the position then cut your slot. People are going to say to use velcro for mounting your lipo so you can use different sized lipo's, I prefer the slot method if you intend to stick to one size battery. Another method once you have marked the position of you lipo is to temporarily attach it to the fuse with pins, fly it and make sure it flies to your liking before cutting the slot.
I find Herc's 82.5mm from the leading edge of the wing works well for me.
Thanks! I was able to figure it out last night and I think I got it balanced pretty good.
