Gliding in general really is a mess with brake fluid types. Schemp hirth and grob gliders all use DOT 4 AUTO, Schliecher all use AVIATION FLUID. StOCk standard dimona h36 use DOT 4. I am uncertain re hk36 but would be listed in manual. I encourage owners, to clearly label at filler cam the brake

Gidday Kurt, I may be able to shed some light there. Not sure if yr H36 is ex Thai but military tend to ignore any manufacturers type certificate, Plus the normal brake fluid they use is the aircraft stuff. So dot4 is of course automotive. It does sound as if U will need to replace all the

If you buy the Great Plains cylinder heads, they will machine them to the right cylinder size but you will have to adjust the size of the combustion chamber to get the correct compression ratio. *Please Note: I have not used these Great Plains heads and in most countries you will have to get
