    Recommended gearing.

    Hey guys. In my rustler 4x4 vxl I am currently running the stock 3500 motor with a 13t pinion and a 50t spur gear, or a castle 4600 kv motor with the stock 11t pinion and the same 50t spur. Does anyone suggest different gearing? It seems rather slow, but both of the motors get pretty hot...

    3s. IMO 2s is for babies(if they are bashing, 2s is great for track racing.)

    IMO, you need a lower KV motor to properly run 3s consistently. A 2500-3k Max KV motor. The 4600kv isnít made for a 4wd vehicle like the rustler 4x4, and the stock 3500kv motor isnít really made to run 3s consistently IMO. Maybe if you gear down real low it may work, but I am pretty sure you will still have heat issues on 3s. And the 4600kv motor on 3s in that vehicle is just too high a KV. Itís spinning at nearly 58,000 rpm unloaded with a fully charged 3s lipo. Like I said, you really want to run 3s all the time, get a lower KV motor and a larger ESC as well. JMHO.

    I have a hobbywing 80a esc. I also have a tazer dynamite 45a esc. I have a 3200 kv motor, but it handles more like a 2500 kv motor. It has super torque, and not very good top speed with stock gearing. I run it with the 17t pinion on a 54t spur, and it gets about as hot as the castle motor does on 2s... it is also way faster.

    Well at that rate you are up to what pre-teen I guess. Don't worry tho you will grow up to 6s and then I will take you out for shots.



    This is just a joke please don't take seriously.

    i have a 5700KV and a 17T pinion it got Very HOT just a few speed runs. i just ordered a set of 13,15,pinions. hope they will help but im just guessing my 5700 castle is to much KV. was going to order the 3500 stock motor but not sure something better isnt out there.
