Two channels and an 01. I have another with a Futaba escapement system...

I love it. I am now working to set this one up for laser cutting. I have modified by stretching the nose 1 inch for better balance. Dad has one I bulit for him some years ago as a pulser. It was hard to balance with .020. Have you had any trouble?I need to beat you out of some of that checkard silk!!!

Both of mine needed a little lead, even though I have a large homemade brass tank in the nose of each. Extending the nose is a good move.
I've used 01's in both, an 02 would be overkill!
Thanks on the checkerboard comment...this one is actually checkerboard tissue! Have to be careful not to poke any holes!
Yes, you will have to fight me over even small scraps of checkerboard silk or tissue!

Yep the .020 was a little much but she would tighten up in a loop forever driving the multi channel guys crazy with "How he do that?"
