Jetboat shell and nozzle mods

Finally I've finished it... and assemble. will publish a video later, when test on the big water.

My shell's split with guides for correct assembling. Used 2mm carbon tubes or even toothpick should be ok. Length is about 10mm, better use 9.

+ Add mount holes on the rear for nozzle. M2x8 should be good enough
+ Add three 5mm holes for 5x1 silicon pipes for electronics cooling. Two for input and one for output.
+ Increased hole for the shaft to support mr74 bearing.
+ Modify nozzle for two cooling jets (still under design). 2 pipes will be passed inside the shell and joined into one. Will design joiner for pipes later.
+ Servo mount with 8 mount holes sets to align height of the servo (used MG90S). Please refer to the picture how it is located inside the shell.
+ 2 props (3 blades and 4 blades) (used one of the openscad lib found here with some mods, but can't find one more time to post the link)
+ Deck split. 2 variants of back. Straight and with air wing.
+ Motor mount for
