I am going to be running brushless (Castle Creations 7700 or Novak 3.5) and a Spektum DX2. I do know I want LiPo 2 cell, but not sure what will give me decent power and run time, and still fit. I am completely in the dark about chargers. What will charge and balance the battery from an AC power source? What gearing should I go with? Please remember that this is not for someone hoping to compete in the nationals, or even club racing. Just someone wanting to go fast around the neighborhood.
An Onyx charger would probably be something you'd look foor.
They can run off AC and charge Nimh's and Li-po. I don't believe they balance Lipo's however so you would need a balancer such as,
Your Lipo's, depending on what they are, should be balanced every so often but balancing them every charge would be good.
As for what Li-po, not sure about where you are but at my LHS there's an LRP VTEC 5300mah 2S2P lipo which is designed to for where Nimh packs would, going for £75 which i think is a fair price. Most things by the major brand should be ok for what you're using it for.
If you are using a 7700 or a 3.5 Novak as you mentioned, you would want as bigger mah battery as you can find, even for just bashing, the 3.5 and 7700 are going to draw mega amounts of power from your battery even compared to a 5.5 or a 5700.
It's just a limit on your funds after that :P
Good luck and have fun
