RC Boat Mystic C5000 electric project

Impressive hum?
I am now starting the project of my mystic c5000 too. I'll post here the results of the project.
Today I will do the laser cutting of the pieces I designed

Super Hawaii R/C boat gas conversion

Today more and more people prefer the electric motor the gas engine. The LiPo batteries and brushless motors contribute to a performance unequaled. But have your own disadvantages, one of them is the price of materials and battery charging. The gas engine, although more noisy, dirty, has the advantage of being cheap, have a more linear power.
The Super hawaii is an excellent boat, a little bigger than I Gancia Gancia and Cesa has a very good behavior in the lake and sea. Originally brought from the factory four electric motors 540. In his time (80's) was not yet available lipo batteries and this was a problem. With nicads its enormous weight and so I opted for gas engines conversion. Today I confess, I am tempted to try using origin abc hobby electric drives with new brushless technology.

R/C Jetboat twin nqd jetdrives brushless experimental

A clumsy test of my little model designed by my self to use two nqd jetdrives with brushless motors.
It was entirely constructed of balsa and their total weight does not exceed 600gr.
This test was performed without the cooling system and therefore  I not sped and small pool does not help. When it is finished I will test it in open water and post the movie.
