Customer Reviews

Cheap, & it works. Review by GLwagon
I have a couple of Power HD LW-20MG, & they have been solid in a Axial SCX10ii, & an old Tamiya CR-01.
Not a 430+oz monster, but not priced like one.
Has survived many trail & crawling runs with no signs of failure.
Full lock against the rocks & it won't pick up the front end, but doesn't overheat & quit working either.
Just enough servo for an average crawler.
Gear set seems solid, many tumbles with no servo saver & haven't blown it up yet.

I did remove the case ends and add more waterproofing.
The factory board did appear to have a conformal coating on it; However, I personally re-waterproof my servos for a piece of mind.
"GE Silicone 2" in the backplate.
"Dielectric Grease" on/in the gear case & output shaft. (Posted on 4/4/2017)
