Yeah well, i sold my boat and with that money i bought the arms:)
I looked at the measures from some 6s 5000mah lipo's and it fit's on 1mm....
Going to buy the motor first and then i can see the real space what's left for the lipo. Just in case 6s wont fit, i haven't bought such an expensive lipo
Ehm, why making a difficult mount when it can be done easily

I think i make a new one because of the flm shocktowers, this wont fit because these mountingholes are based on the original towers...
btw, how is my english? I think it sucks
Keep ya updated!
Greetz,
