Brushless ESC

[Ryanf58]

Is there any way to waterproof a sensored motor and esc? Want to put brushless in my SCX10 so I can do more of a trail truck but would still like to crawl with it so I know most people say go sensored for that. Was looking at a hobbywing combo as that's what I have in my Yeti and like it. Or is there any way to adjust the settings of an esc to give better low end on a sensorless system?

Use conformal coating to waterproof the ESC board and sensor board of motor.
I made some videos a while back for instructions.

If you update your records firmware it should help with low end control.
Also you can adjust throttle curve to give better start up.
Playing with the sensorless timing will help too.
All settings in esc.

Hobbywing is great. Personally I like the castle mmp and choice of motor. I have leopard motors, furniture, hobbywing. All perform decent. I go everywhere the expensive motors can go.

As for the sensor wire connections use some waterproof di-electric grease. Using conformal coating on these very small connectors is not going to work.

Thanks for the responses. I'm probably going to end up using the Hobbywing Max10 SCT 3200KV combo on my SCX10. With throttle curve I can give myself the low end when I want it but still have some speed.

If your plan is long term submersion, I agree. I use just conformal coating on all my electronics with zero issues. I run them through whatever.
Dielectric grease is a good addition, but not substitution. Put some in the sensor port after conformal coating.

As for your motor choice, 3200kv even with throttle curve adjustments and low gearing is still going to cog at low speed. IMO sensored is the way to go no matter what. I'd rather have sensored and be less efficient than sensorless and have cogging.

I have that combo on my Yeti and don't get cogging when I put barely any throttle on. Will the gearing of the SCX10 make that much of a difference? I've been out of cars for awhile so not too familiar with these systems.
