    Castle 1415 2400KV Gearing Question

    What gearing and Lipo do you-all run with the 2400KV?

    What temps do you get on the motor?

    I run 17/54 on 3s and have the feeling motor temps to be little on the warm side like 150F?

    I don't know if i am under- or overgeared. ESC temps are very low and i run mostly around half throttle.

    Since i run in a rather small bashing spot with some jumps and U-Turns there is a lot of stop and goes too.

    THX!

    EDIT: Top Speed calculator says 48 mph - pretty fast

    Ok so today i got 158F max. / Outside Temps: 60F

    So this is a little to high to my mind.

    ESC Temps: 113F

    The motor temps are fine as long as they don't go over 180f and the esc over 150f.So you are all good dude......peace

    Thanks!

    So i decided to try a 14T pinion instead of the 17T since i want to run the motor as cool as possible

    I had to dremel a little bit more off the chassis to make the motor sit perfectly, but was pretty straight forward.

    Also i set punch control on the WP-SC8 from 5 to 3, since it got even more torque with the smaller pinion.

    If the weather stays like this i'll try that setup tomorrow.

    I hope its dry tomorrow too because I love my new 3s pack it makes my pede go crazy man.And my new settings are punch 5 with the revo slipper set at 3/4 turn from tight and you are right its very hard to get my truck up to full speed running 15t pinion with a 3500kv 4 pole so one day I may try 13t pinion and 52t spur for more torque and acceleration .......peace

    Nice! Today i ran with the 17T / 3s and the Pede is much too fast. Speed calculator says over 46 mph.

    With 15T I still get about 40 mph top speed which is more than enough

    Mine on 3s is around 60mph which is crazy fast that's why I changed down from the 17t pinion to 15t but its still a bit to fast because speed runs get boring quick and speed runs with a monster truck is like taking a supercar to a short course track.....peace

    Yeah i am not a big fan of speed runs. They get boring pretty quickly. I did those speed runs back in the days with my mini e-revo on 3s.

    Great weather today and time for another test session:

    With 14T Pinion and Punch Set to 3 the Motor Temps today were 137F but still more than enough power and top speed with a 3s pack.

    Also the Stampede was much more easy to control and throttle was not so sensitive anymore.

    Just found my personal sweet spot with this motor and setup.

    perfect - love it !!!

    One thing i noticed is that the Low Voltage Detection of the WP-SC8 kicks in little to early. At the end of the run i still got 3.69V / Cell. Think i will set it from 3.4 to 3.2 (default) again.

    The LVC is kicking in because, under a load, the lipo voltage is dropping below 3.4v/cell. It'll always be a little higher once you pull it out and check it.

    Just make sure the cells never go under 3.0v or you will wreck the lipo dude.......peace

    I set it to 3.2V today and got 3.5V after the run. As soon as i arrive at home i recharge to 3.8V.

    Nice!!!! I am still working on my single With my mini e-revo i could also do front flips. don't know if the stampede can do them too. I just hit the brakes in the air as hard as possible and the mini revo would front flip
