1954 hydroplane

well not built in 1954 ,but taken from a pratical mechanics magazine from 1954 of a one person hydroplane boat that uses a 5to10hp outboard motor, i'm hoping to build one oneday but i wanted to test one so i built this one as per the original design,the outboard on the model does push the hydro along ,this i moded with 380 motor, running on 8.4volt 900mah ae size cells, supatec micro servo , standard 2 chan rx 15amp speedo.the yellow one is a modern design from the states.

That looks like a hydroplane, not a hydrofoil.

Yep , that is a hydroplane. Still raced in the UK in that size. Usualy up to 1 litre both outboard and inboard engines. Midlands , Essex and Oulton Broad are strongholds. Exciting to watch, bit like speedway on water with heats. The unlimited classes in USA are realy amazing with Merlin engines now being replaced with gas turbines.

Great model and different which is what makes it so intresting!

Can i ask why you opted to use 8.4v not 9.6v or 10.8v?

because the boats only 300mm long , and is plenty fast enough with this set up.
