Senton Upgrade question

[Cards]

I upgraded my brushed 550 Senton Mega to Spectrum Firma 3300kv motor with 3s lipo. This has 3mm motor shaft. Thinking of upgrading the slipper clutch/spur gear? If so, what pinion gear is needed?

Hello and welcome to the forum.

If you upgraded from the brushed Senton to a 3s system the stock pinion is 20T on the 3200kv motor. For the slipper clutch you can buy the full replacement from Jennysrc.com

Well since you bought that motor you will have to stick to 1/8 or 3.175mm pinions, no need to change the spur or slipper really, you could add the motor plate for good measure, plus they are cool

Thanks! The Mega comes w 17t 48dp pinion. Spur is 91t. Would you recommend any other pinions sizes?

Appreciate the info. Unfortunately the stock pinion is a 5mm, and the motor I purchased has a 1/8th inch shaft.

As far as the slipper and spur gear, since you have that motor just leave it, add the motor plate and get some 1/8 pinions, I'd start with the 16-18 tooth.. see what motor temps and performance does, might be ok with a 20t

Stock blx 3s carry a 100a esc and usually the 3200 kv motor, ur a tier below that so just depends on what your looking for!?

I apologize, I should have been more specific. The stock pinion on the Senton 3s blx 3200kv motor is a 20t count. Below are the 1/8 bore (3.175mm) mod 0.8 pinions that will work with the mod 0.8 slipper clutch I posted.

Alternatively you can leave it alone as Senton pointed out the 17t 48dp stock pinion will still work with that motor.
