Hey RYAN888.
Seems you know what you are talking about so I am Going with a biggish brushless, single drive, 4mm shaft( for prop availability), and I have just spent about 2hours attacking the lead sieve with Mr Dremel. I have just finished making a turn/spin fin out of aluminium and I will fit a surface prop. The hulls will be glued back together to stop the sieve from leaking and the sponsons and unused hull areas will be filled with foaming resin. If this doesn`t work I will make a nice lacquered wooden stand, strip out the hull then put the TUB on the mantlepiece to collect dust!!!! Tell me, what do you think?[][][][][][]
