Hey Guys i was wondering what the ideal port length and width was for a half bridge motor 13b? how about spacing between the main port and the secondary?

I want to try and port a junk housing to see how i do and was wondering if i could get some help.

If it works out i can put the drawing in cad and send out templates.

any help would be awesome.

 

best bet is to slap a rotor on a housing, then trace its path out on a piece of plexiglass or lexan. you can get either at the home depot for like $5-10

depending on if you notch the rotor housings or not, the extra port width is typically from about 4mm (which i feel is too small), to about 8mm. you should be able to get about 5-6mm easy before you have to notch the housings.
