Hydrogen Engine v2

This is the mostly working version

use the videos to show how to build

did a lot of variants to get to this model version

This is a hydrogen engine which should work but is quite complex.
Watch the vids for details
firstly the cam belt will need to be Tpu/ other flex
the Cylinders will need to be sleeved with a metal ring
the tops of the pistons and head will as well
you will need an electrolysis Hydrogen generator
the sump will need to be filled with cooking oil
foam with oil on will need to be in the air filter
this block can only be run for a short time as there is no water cooling this will come soon
the valves need springs under then
it will need RC plane spark plugs you can drill those holes in the head to suit
it will need metal on the flywheel which is PERFECTLY centered (use a lathe)
8mm bars for the crank
this needs M3 bolds of varing size, heat then up a bit before screwing them in and then it wil thread the holes

have added a water cooled block no
