Fireboat & Suction (pick-up) Hoses
Thanks to all those that made suggestions about making the Suction Hoses, here are my efforts. The boat looks OK now thought there is much to do still. I am using two Johnson drill motors in paralell with one 50 amp ESC & 20A fuses in each motor + supply lead, all running on 8.4V NiMhi. the current props are 40 X 21 three blade. The boat is fast enough but battery life is short and the battery is very hot after the end of the run. I water cooled the motors and ESC. I will try some smaller props and 7,2V to see if there is an Improvement.

The mast is scratch built from 1mm alloy sheet & a few sizes of oaaly tube, the fittings set came from Model Slipway:
http://www.modelslipway.com/ about A£40.00 for the set including p&p (1:16 scale only).
I made the hoses from coil springs covered with heat shrink tubing and machined the end fittings from brass. Took about a day!
I'm now running it on a 4Ah 2S Lipo and get about 40 minutes running per charge.
Good luck with your boats,
I like the design of your motor cooling, what tubing did you use to wrap around the motors?
