14.5 * is writen right on the revo 36 tooth gear.

I never said anything about mixing different brands of gears with each other either, I just posted a write up that says your not supposed to mix gears with different pressure angles with each other.

So in short, I think you are looking into it too deeply. I can see this as a possible problem in a precision mechanism.....but a pinion/spur combo??? What I can say is there are bigger problems to worry about with a high speed car build than this! Good luck with the build!!

If you read the write up I posted ther are only 3 types of mod 1 gears 14.5* 20* and 25*. If one manufacturer makes a mod 1 20* gear it should match perfect to the other manufacturer 20 degrees mod 1 gear. 20 degrees is 20 degrees its a universal measurement I believe and there is no metric or foreign equivelent form of measurment for degrees .There should be no descrepencies between 2 20* mod 1 gears at all made by different manufacturers period. If there is, then one manufacturer is making them wrong. Yes it is just a spur and pinion the 2 peices that mesh together and all the power goes through. I may be looking into it too deep but thats just me I refuse to 1/2 ass something together and hope it works. If you still want to argue about the different pressure angles of gears dont look at me its not my rules. I am sure some dumb ass engineer with a phd thought of it just to screw with us and make things difficult . The biggest problem I had was tires and I now have that solved. My first goal is to break the current isc record of ~70 mph. Second goal is to break 100mph so well see.
