Hi noguy,

I would consider going with 2600-2800, or more, as higher head speeds often improve stability. Also be aware that higher cap (heavier) battery packs do not always give longer flight times. This is something that I've learned the hard way with fixed wing electrics. The trick is to find the right balance of head speed, pitch, battery power/cap, and model weight, that best suits your heli and your flying style. Glow powered helicopters sound pretty good right about now huh? Just my .02 worth.

Good luck and good flying!

P.S. Check out "dhrc.rchomepage.com" as this site has a section on this topic, IIRC.
