Stages of Cheap/Expensive Builds/Upgrades for TRX4m.
Cheap build ( what i use and some i think is best )
Brushed ESC: TRX4m Injora MB100 ESC: https://www.amazon.com/INJORA-MB100-R80-
Key features, Blinking when low battery, Motor Overheating automatic shut down, low speed control, silent ESC, great or better than Stock ESC from Traxxas.
Transmitter + Reciever,
The one i think might be the best deal is the Dumbo Rc Transmitter ( 2025 Updated version new remodeled transmitter with screen )
This one has a screen with more options and settings unlike Dumbo Rc ( older version ) Transmitter but the older one is still great.
New Transmitter and Reciever, 75$ : https://www.amazon.com/INJORA-MB100-R80-Brushed-
Older transmitter and reciever: https://www.amazon.com/INJORA-Transmitter-Controler-
Motor, Stock Motor has great power but isn't great because it has a bearing but idk i guess its better than all of the motors, Meus randomly broke or idk what happened, ( I reccomend buying it near your local hobby shop because they mostly carry it there if they sell traxxas parts. )
Transmission: Theres many transmissions like the Meus 2 speed transmission or the Injora upgraded transmission or the stock one, idk whats best but you choose
Injora Upgraded Transmission: https://www.amazon.com/INJORA-Aluminum-Complete-
Injora Aluminum Housing ( no gears ) As stock: https://www.amazon.com/INJORA-T
Injora Plastic ( as stock ) Transmission With gears No motor ( Clear color ): https://www.amazon.com/INJORA-Acrylic-Complete-Transmission-
2 speed transmission with motor or no motor ( dose not fit some upgraded parts ) https://www.amazon.com/MEUS-
shocks: 59mm or 53mm shocks from injora, i have 59mm Injora's and it works well
53mm shocks: https://www.amazon.com/INJORA-Shocks-Absorber-Threaded-
59mm Shocks: https://www.amazon.com/INJORA-Threaded-Absorber-Crawler-
servo, I think the best servo is the Meus Coreless or Brushless TRX4m Servo ( not tested ) and the 640T Eco Powered Servo ( i have )
Eco Powered, Slow not super strong but reliable servo. Get in store or on Amazon
Meus servo, Not sure how powerfull it is but if its brushless it should be good.
https://www.amazon.com/MEUS-Racing-Brushless-Shifting-\
Tires and rims, I think any Injora Wheels are fine, Amazon sell em. Grippyest compound is S5 and needs Beadlock rims ( if wanted but will slip if not )
Harden Steel axle ( hard to find part, Redirected to Traxxas Website Upgraded Harden Axle " Stock size ) : https://traxxas.com/9756-hardened-steel-axle-set
This part is 40 Dollars. You can probally find this in a hobby shop but idk. Injora TRX4m Harden steel axle has +2 MM which Idk if it will fit.
Diff's , Im pretty sure i have these ones: https://www.amazon.com/INJORA-Alloy-Steel-Helical-
Battery, i think you should get the stock TRX4m Battery because its probally best and you can get a 750 MAH or 1000MAH battery which i have. you can probally get inside a hobby shop where i got mine.
Driveshafts, I think the Stainless steel ones from injora is probally the best. I have it and it works really well.. just make sure to put it in correctly so it doesn't bind.
https://www.amazon.com/INJORA-Drive-Center-Crawler-
Screws, Traxxas TRX4m screws from Traxxas is good and i think you can get it in hobby shops but heres the Traxxas website, This is the full kit by the way so no need to buy another. but you may need to because its 3D printed and some take more screws i think…:
https://traxxas.com/9746x-trx-4m-stainless-steel-hardware-kit
If i have missed anything please contact me so i can add it, i think i have everything.
Honestly i think building a TRX4m from the ground up with injora parts and real aluminum parts thats not 3D printed i think it would be even more capable because it won't break but its your choice.
Welp, please do NOT remove this makerworld im tired and i have spent 3 hours writing this.
