The Astro 010 10turn w/9T pinion and Castle Creations Phoenix 10 is what I am using and works great on a 7.4v lipoly. I REALLY LIKE THIS SETUP AND HIGHLY RECOMEND

[link=http://www.b-p-p.com]Bishop Power Products[/link] sells this combo for a good price.

If you can't go brushless then the Acro 280 6v is an OK choice but I found it too be underpowered and gave less run time and made my 1200 etec work really hard...........

BTW, I am running the stock tail and MS CF main blades
