Savage HP Waterproofing

[CountryBoyCanSurvive]

Hey guys, been lurking for a while, finally made an account.

Picked up a used Savage Flux HP a little bit ago and I'm working on making it waterproof (more like resistant, I know). I ordered a Castle Mamba 2 for the esc. Having trouble picking out a good servo. Anyone have a recommendation? Preferably under a hundred bucks and at least matching the stock specs.

Thanks for the help.

Faster and 110oz/in stronger than stock for $82.

I run a hi tec 7954 in mine,, super smooth, plenty of power.

I just noticed that my truck has a HPI SF-50 upgraded servo in it, running 266 oz/in. I see there's an HPI SF-50WP, waterproof version of this servo, with 288 oz/in and available for under $50 used on eBay. Anyone have experience with that particular servo or a comparison vs the Savox servos?

Pretty sure that's 166oz-in (12kg-cm).

For a MT, I'd find something that has 180oz-in+. I run a hitec 985MG which is 172oz and it does ok on my revo's. Not great, but does ok and seems to hold up for many years.

I was looking at the HPI Specs page:
https://www.hpiracing.com/assets/documents/instruction_manuals/105369-sf50wp-glb-m-v1.pdf

It lists the SF-50WP as 288.8oz/in at 6v and the SF-50 as 266.6oz/in at 6v. Are their spec sheets overrating their stuff?

I hope that's accurate, because I ordered the SF-50WP for $47 shipped. Seemed like a pretty good deal if the torque is there. If it ends up being too weak, maybe I can toss it on my Jumpshot and get the Savox you recommended for the Savage.

Well, one of them has to be wrong because it doesn't convert that way.
288oz-in = 20kg-cm
12kg-cm = 166oz-in
13kg-cm = 180oz-in

I'm using this tool:

using 12kg-cm:

using 13kg-cm:
http://www.convert-me.com/en/convert/torque/?u=kgfcm&v=13

using 288oz-in:
http://www.convert-me.com/en/convert/torque/?u=ouncefin&v=288

I'm guessing it's a misprint in the pdf you linked.
Tower has it listed with the following:
Voltage: 4.8 - 6.0V
Torque: 166.6oz/in (12kg/cm) at 6.0V
Speed: 0.18 sec/60° at 6.0V
