Servo Question

[NitroNoob]

Anyone know if you can use a Hi-tec mg645/mg625 servo for throttle/brake. I am trying to find out if I will need any additional parts then those that come with the servo. Since my little accident, I am would like to replace the SF-2 servo that was running my throttle/brake with a higher powered servo.

Any suggestions.

I run the 645 for my throttle and brake, very powerful but not very fast. It does drain your batteries faster than the stock servos so make sure you run a hump pack or have lots of AA laying around.

I use for throttle and Steering. For the Hump pack go to Ballistic

I already have an 1400 mah hump pack in my truck. I just need to know what else to buy in order to be able to install this on my truck. Is there a servo saver that I can use for this, that will work on the Hi-tec servo for the throttle and brake.

Do you really need a servo saver for Throttle/Brake servo? As far as my knowledge goes, you don't because there is nothing to pull the servo real fast, like wheels in an accident. Unless you were talking about steering servo...

yeah there is no need for a servo saver on the T/B servo's. Definately use one on your steering as that will chew up your gears real fast.

get a hitec 625mg. Its about what you would want for t/b and to me its perfect for the truck.

This is what Im talking about, I guess I'm confusing two different parts:

servo horn

[Technical RC]

If you are swapping the stock servo for a Hitec servo
you will need to purchase a plastic parts "tree" number
85051 and use part #17 from that tree. It should cost
you about 9 or 10 bucks.

The reason you need to change that part is because the
output shafts on the stock servo and Hitec servos have
a different number of teeth on them.

Or check your pack-in parts from the original purchase of the Savage. It came with 23, 24, and 25 tooth servo horns. Pick out the 24 tooth, and modify it with the ofna slider kit, like you did for the Stock servo horn.
