Hi Robert,

Doesn't the link in my previous post work?

Those are the cells I ordered for my competition boats, (and paid 4,10 per cell + shipping)

For the RTR with the Lehner, you'll need 20-24 cells, depending on your need for speed.

You can order them as two 10 or 12 cell packs, so you won't have to solder them together.
Ask with which connectors the controller that comes with the boat is equipped and get a couple of extra. (you'll need the extra connectors for making charge-wires and a few to solder onto the battery leads.

If you want to run the boat more than three times a day, order 20 or 24 cells extra.
Your cells need to cool down to ambient temperature, before they can be charged again.
(on racedays, we use computerfans to speed up the cooling)

Charging: do you have a charger, suitable for 24 cells?

Radio: I'd go for a 40 mHz FM radio set, no interference like the 27 mHz AM radio's sometimes suffer from.

Ask if the boat comes with an aerial (antenna), otherwise, your local modelshop should be able to provide you with one.

If you have more questions, fire away!

Regards, Jan.
