Want to fly all day without recharging? Want to forget about cycling NiCd batteries and quick charging at the field.? you could try NiMH battery packs. A great place to get them at which is highly recommended here at RCU is Radical RC from Ohio.

I replaced my 600mah packs with : Tx- 1650 mah NiMH $30.00
Rx- 2100mah NiMH $18.00
these are Sanyo-the best brand.

Quality is terrific.

NiMH have NO memeory effect problems and can be charged just as easily with the same equipment you would use for NiCd IF you don't use fast chargers at a high rate. You will never need to do this anyways with these. I'm not trying to start a discussion over which battery type is better but after myself and many others have used them we would never buy smaller capacity NiCd again.

Last month, I wanted to practice my taking off and landing. Believe it or not, I flew the plane, non stop, taking off and flying around and landing, FOR 4 HOURS STRAIGHT!! With the NIMH they were only down to 4.9V on the Rx and 9.8 on the Tx. In other words, I could have flown even longer! I for one am completely sold on these. The main selling point I think is that for anly a FEW dollars more, you can have higher capacity NiMH instead of lower capacity NiCd.

Why use a lower capacity battery on the TX?

That's because like one of the guys said, the Tx has a constant, slow drain on its battery so it wears down at a slower rate than the Rx.

What charger would YOU use?

Well, the one that came with your Tx system is probably too weak for higher capacity batteries. You could buy a field charger which will charge both packs at once and allow you to vary the charge rate to suit the capacity of the packs OR you could do what I did and buy another wall charger like the one you now have but which puts out a higher rate for higher capacity packs. This charger can be plugged in and left on without worry about frying the packs etc. etc.

Where do I find one of these?

The best place is Hangtimes Hobbies

The one I bought puts out a rate of 180 mah on the Rx and 120 mah on the Tx.
It will charge BOTH packs at once.

Check this stuff out and you won't be sorry if you buy these. It has been the best thing I've done for my enjoyment of flying.
