zsnugz,

I've heard 4-stokes get better fuel economy than the 2-stokes so maybe that makes up the difference. It's just that I've been reading where some of the guys have been upgrading the tanks (so I had to ask), and it's not much bigger than the tanks on my .46 planes ... but with a normal size engine I tend to agree with you ... if it works, don't fix it.

Ya, I guess running 5 high-torgue 3010's, a standard 3004, and a reciever ... all off of a little 4.8v 600mAh battery is asking a bit much. If it would only last for 1or2 5-10 minute flights before a recharge, that's a little too close for comfort for me.

I think this is the proper one, and the price is right:
