Hi again,

It's probably not a good idea to fit a LiPo directly to a receiver, as they might not be happy with the max voltage of 8.4v.

Instead, either use a speed controller, which will plug into the receiver and supply it with 6v, or use a voltage regulator. I'll be swapping or selling them at the next AWS.

As for recharging, you'll need a special type of charger which typically requires its own 12v power supply.

So LiPos are a third of the weight of NiMh, but there's a price to pay in charging it.

Is there such thing as a NiMh charger that doesn't need a power supply?

If you got a Transmitter charger that you can charge Reciever battery with aswell, then yes, but they take usually long time to charge with.

NiMh chargers are usually mains powered.

Mine plugs straight in a wall outlet.

T2M Swallow AC/DC2

It can charge 1 to 14 NiMh cells (1.2V to 16.8V) at a maximum of 5A and up to 5 cells Lipo.

It also sold under various other brandnames. Technobots sells them as the Pro-Peak Sigma AC/DC charger.

I buy these batteries for ?12 and amongst many, I use this charger which retails for ?35.

I'll be bring a voltage regulator circuit along on Saturday as well to sell or swap.

I don't understand your question about the 3rd channel. What happens when you plug a servo into channel 3 or the receiver?
