I have a 600 mah standard pack for my 9c. What extended battery do you recomment I purchase? I currently have duralite rx batt with a charger, but the duralite only makes a 1300 mah tx pack. I see that I can buy 2100 mah Ni-hm packs for much cheaper without having to buy a special charger. Any recommendations or should I just fork over the cash and get the duralites. I hear that Li-pos are much better for durability and reliability...
thanks

I've been using a NiMh pack from http://www.allerc.com for about a year. 3 times the capacity of the stock pack. No problems.
Also, only $20.

I just installed a fresh 1100 mah NiCd in my 9Z, and I flew for two days w/o needing to recharge. The 1650 or more NiMH's are OK, but you need to have a charger with a high enough rate to do the job in a typical overnight period. Remember, too, that hydrides will display as much a a 50% reduction in useable capacity when the air temps start getting down to or below 50d F. Given that your winters are seriously cold, take this into account if you plan to fly a lot in cold weather.
