What jackets would you use? I can't seem to find what would fit exactly. Some OSE jackets provide no info on internal size, just outside

Might have to make you a CF or FG one. Pretty simple to do. Use 0-rings that fit but also seal it with RTV sealer. If nothing else then make a good coil from alum...better than nothing.

The reason for this is simple. If I provided inside diameters people would use them on motors have have not been tested and when they didnt work, they would want to return them. It used to happen and I was tired of it.
Just because a company lists their motor at 36mm, doesn't mean its 36.000mm. As a matter of fact. Most are not. For example a Ammo 36 and Feigao 36mm wont use the same diameter jacket.

If it is listed in exact mm one can measure the motor and see if it fit.
it is strange the two "36mm" motors are not the same size.... crazy. I suppose this is where caliper comes in to play.

Sorry, its not something I want to get involved in.
For the most part i test or use what I sell, so I know it works.
OSE is a second business, so my time is limited and I avoid as many problems as i can.
