I had the samething happen to me when I put in my 645.Are you using the stock radio? If you are all you have to do is filp the servo switch on you radio to the up position.This is on the left side of your radio beside the steering wheel when you are looking at it.This should take care of your probblem.

Yep, just reverse the servo throw.

 

[sky4max]

thank u

it works

 

[Oh Gee Jay]

what if you have a different remote like hitec aggressor srx

 

[AllanQ]

same thing. Most TX's have some sort of Norm/rev function so you can change the servo throws, so when you upgrade a servo or radio system, that setting sometimes needs to be adjusted.

 

[Oh Gee Jay]

yeah after i posted i looked up the instructions for it and changed it thanks anyways

I have had mine for over year and haven't had any trouble with mine..Not a bad upgrade for the price..

did you put metal gears on the inside or just slam it in the sf 1 slot

I just put it in the sf 1 slot...

 

[Lexpert81]

ok just wondering if it needed some upgrading before putting it in

 

[sky4max]

.Not a bad upgrade for the price..

this what I'll say

by the way
you can find Hitec 645mg in hobbytown for 35$

i have this servo as steer in my savy & HF. thought it was a 'good servo for price' and it is, but after runnin it for a while, just not enough torque or speed to be what id consider a "good" servo to steer a savage. i say if your current servo is not broken, then wait & save few more bucks till you can afford a better servo.

saving up for a better/stronger one now.

 

[Lexpert81]

i am pretty sure i broke the stock one it clicks when trying to turn and feels loose I just bought the hitec 645 and bearings hope they come in the mail soon what servo are you saving for that is better

 

[frddyj]

after research (basically askin peeps with experience using different servos) any of the usual brands with a minimu 200oz/.15

 

[sinisterRC]

I use the 645 for steering and the 545 for throttle, no complaints. Sure there are stronger ones but for a basher these will work fine. Now all I need is the 3PM to compliment my servo's!

ya thats pretty much what i did. bought the 645mg to replace damaged steer servo, then 3pm now upgrade to a Digital servo with more power to run in PPS mode with digital 3PM

yea I should have gone digital, I guess I'll upgrade later.

 

[Lexpert81]

hey i am a total rook with this what is this 3pm you talk about and what is running in pps mode also what do i need to switch to all digital later

Thanks Dave

Welcome Dave. The 3PM is a Futaba 2.4ghz radio system, it is the one of the most popular upgrades for the Savage. As far as PPS mode, I believe this activates a fail safe (in case your truck either goes beyond the radio range, or your battery dies) the throttle servo goes back to neutral. That can really save your truck. You can only run in PPS if you have digital servos otherwise you will fry your analog servos. But if you don't have digital servos but still want to run the 3PM you can run it on the other mode (not sure what the code is). Hope this helps.

Thanks for the help man you and everybody here has been great
I love this site

Yep, just reverse the servo throw.

That's correct just reverse it if your radio supports it. Same thing happened to me and I was able to figure it out by reading the manual page 47 on my Futaba 3PM. Just a reverse function.

Just put in my hitec 645 and steering bearings it was pretty easy will fire it up soon to see how big of a diff it made thanks everyone for your help

 

[xll-SavageX-llx]

there should be 2 switching on your hand set, one is for throttle (break is gas & gas is break) or the steering one ( eft is right & right is left) try that !

 

[Lexpert81]

Finally ran a tank with the steering bearing upgrade and a new hitec 645 steering servo and it was sweet it turned so nice really fast and smooth. I am really happy i did this upgrade. Thanks everyone for your help
