Pinion/Spur selections for speed run car
I am building a TC3 speed run car to run on 5s Lipo and a 2600kV motor. I want to gear it to run about 100mph(on paper). I realize this is a bit outrageous, but thats the idea. My problem is my motor is a 5mm shaft. I found KershawDesigns has 5mm 48p pinions up to 47T, but they are $30 shipped. I have a challenge to do this under a tight budget, so those are likely out of the question. I am not against changing to another pitch, but I cant find a match for a low enough ratio. if anyone knows of any ideas please chime in and help a brotha out.
I know there are many problems associated(hehe) with getting this car to go that fast, and I am well aware of most of them. I have seen 70mph with the car already and I saw many problems getting it there from 50mph. Those are problems I am looking forward to. Thanks
