RE: What rtr?
u need sub-c size cells, not 2/3a. too small. you could also just buy the cells and make the packs yourself if you have a soldering tool and batt bars. I bought some 6-cell 3300 packs from radioshack for 25.00 and made two seven cell packs. if u want a cheap boat then just go with a turbo vee from tower. 80$ and they go about 15mph. my friend bought a krontonics sun esc and a 600 motor and it now goes about 25 on 12 cells. on 7-cells it would go about 20-25 for only only 120 for the entire setup. id use a different setup because his motor would over heat every run. heres what u should use...

It isnt a very good looking boat but u could buy a new hull and it would still be cheaper than the others. And it has great acceleration for wave jumping. here is the video for my friends.
