I will use some Futaba 9206's that I picked up at a great price, right before National Hobby Supply went under. 131.9 oz in at 4.8V (they say not to run them at 6V), coreless BB. I have 4 of them so I guess I'll need a few more - I have some hitec digitals that I could use as well.

That's my suggestion for Futaba. Granted they're not cheap, but they should work well.
