Li-Poly Battery Question


I was wondering if anyone could tell me which Li-Poly packs would work for my Merlin? Will I be able to get longer flights and/or lighten the plane using these? I am now using the stock 7 cell 8.4v NiMh "MegaBattery" . There are no markings showing MaH rating, but the individual cells are approx. 1 1/8" X 5/8" . I am told that the motor on the Merlin is a 7.2v type 300 or RK 370. Also a link to the best place to buy these would be appreciated.

Oh, I forgot to mention it is geared @ 5.6:1 and running a 12 x 8 prop.

The ET 1200's would work for your application- email me off list and I'll run some calc estimates for you - we can get you dialed into the right pack / prop.
