I bought a Typhon Mega (my first RC car) about a half year ago. It has been very fun to drive it but now after reading all about your guys speedrunning builds I have to do something similar! So to save some money I’ll try to upgrade my car to a Typhon 3S (without tires and electronics) and from there to a speedrunner, like jondilly and philldogg has done. My plan is to run it on 4S and aim for 80mph!
Here is my part list:
Mamba X
Surpass 3660 4000kv motor
2x CNHL G+ 5000mAh 70C 2S batteries
Ceramic bearings
The old plastic 3S diffs with 13t input gears
High speed center driveshaft support
Adjustable motor mount
500.000sct diff oil front and rear
Turnbuckles
GRP tires s3
The motor shaft is 3,17mm and I can’t find any mod 1 gears with that size so I’m thinking of using a reducer sleeve on my motor shaft so I could have the stronger mod 1. To reach 80mph I would need a gear ratio of 2.5 : 1, but the biggest mod 1 pinion I could find was 30T so if I use that as a spool then I have to use a 23T as pinion, which would make the car way too fast! Can I drill some holes in the motor mount to make it fit, or do you have a better suggestion?
Feel free to criticize my building plan because I’m new to RC and speedruns.
