Hi every one,
This is a great website first of all and thanks to the admin for helping beginners.

I just want a clarification on my batteries to be used in my cougar 3 channel remote which consumes 12 v and the receiver segment which is rated as 6 volts which powers three servos

1.turn control(metal geared)
2.throttle and brake
3.forward and reverse control

Here is my question, i want a solid run of my rc without any range problems due to power considerations. so should i buy rechargeable batteries  in market and install them or buy Ni-Cd or Lipo batteries for better performance? plz specify about the chargers and ratings and performance if possible.

thanks mentors in advance.    

You should be using Rx packs. Check out JRH. They should have Rx packs in stock.

Your Rx is not HV(High Voltage) capable. If you use a regulator to regulate the lipo's output to 6V, you can use that.

You can also use a 6.6V LiFe pack.

i use MiMH packs...

10 X AA batteries rechargeable, preferable every  everyredy 2100mAh.............. which will give u 12V

and
5 X AA batteries rechargeable.. which will give u 6V

thank you AEROVISHWA  and iamhuman, it would be nice if you specify what charger to be used there in each case.
