Steering servo upgrade

[Smileythetrucker]

Well, I swapped my tires to some pit bull rock beasts and my stock tactic servo is struggling pretty bad. My local guy at the hobby shop recommended a Savox savsc1251mg as an upgrade. Anyone used this servo before? I'd love to get some opinions.

Fairly weak servo (torque) for a crawler.

What's you budget for a replacement ?

[Smileythetrucker]

Well I paid $62 for this one...I wouldn't want to spend too much more than that. But obviously as little as I can while still getting a decent servo. Don't want to buy junk.

A few dollars more would get you a savox 1230sg with plenty of torque. This is an expensive area on your truck. Not spending the coin now, unfortunately will cost you later. There are other good options at around 80$. And yes I understand that's alot. Trust me, I really want a savox 2290 150$

So you know the 1230sg is 440oz of torque. A 1251mg says 125oz tq on savox website.

which Pitbull Rock beasts ?

1.9, 2.2... XLs ?

I use the Savox SA 1230 SG to push
4.60" tires on my SCX-10 and it been great.

The Savox SA 1230 SG offers 500 oz in of torque
requiring only 6v to net that.

But tires that are taller then 4.80" (ish)
may fair better with even more torque. ALIMO
But others might disagree.

I run some 2.2 PL TSL XLs measuring 5.80" tall
on my Wraith converted to 1:6 scale (12 lbs or so)
and the Savox SA 1230 SG ran too hot when running those.

Obviously the added weight plays a role.

But on my SCX-10 sporting 4.60" 1.9 tires... no problem.
Probably be fine with a 4.80" (ish) tire as well.

Thanks for the replies! I'm running the 2.2 Rock beast 2s.

The 1230 would likely do well...
as long as it's nearer to the stock Wraith weight.

But a heavier chassis Wraith with near 6" tires... might be a different story.

That's why I pony'd up for the Savox SB 2290 SG
'cuz my Wraith weighs in at around 10 - 12lbs. and sports 2.2 TSL XLs.
The 1230 wasn't cutting it and ran way too hot in my rig.

pricey... but near 700 oz in = monster servo torque

and turns 6" tires all day long, becoming just warm to the touch

But the 2290 would be nearly 3Xs yer budget

I use the below. Works fine for me. I agree more oz the better generally but I have never found this servo lacking.

Would I need an external bec with these servos?

You should notice a distinct improvement with an BEC, regardless of which brand of servo you choose, but in particular Savox servos are notoriously amp hungry & its likely you'll have esc brown out issues without the BEC.

If possible grab the HH rx bypass for almost plug n play ease.
If nothing else it frees up a port on your rx if you'vr got lights etc running off it.

As above you definitely need a BEC. Without it your servo will not be running to its full potential. I personally always buy the Castle BEC as I have various ESCs to. So with the Castle Link I can program the lot.
