NQD jetboat twin brushless motors rc

My little experimental jet boat home made in balsa and fiber glass. I use in this project two NQD jet drives with brushless motors equiped with dual 60A ESCs and 4000 lipos.

Nice boat

Super fast this boat. 186 km/h!!

Closing the hull

 

After closing the top of the hull with plates of 2mm of balsawood, I put a thin layer of filler prior to make the canopy.

Adding foam

 

After I lined the inside with thin fiberglass layer, I opted for the use of polyurethane foam. it is mild and help the floatability  in case of accidents. As well as helping to the firmness of the assembly

 

 

After the "pie" dry, I cut and sanded the excess, preparing the surface to the upper hull.

 

 

 

 

 

Inner lining

 

I coat the inside of the hull with a thin layer of fiberglass before it closes. This will eventually contribute to a better waterproofing and firmness of the hull

half hull finished

 

I finally finished the hull using 2mm thick balsa wood plates in order to keep the weight low assembly.
