Hi guys i recently just added a hi-tech 5645mg servo in my ttr st1. I bought the diff oil but hav not yet put it in. I was at the track today hanging out and driving my st1. A guy there helped me set my servo up after i told him i wasnt sure how to do it. Well i started driving it and could not just get into the corner, the servo puts enough torque out everyone said. But i mean it would just make big wide turns and i could not get into them[:@]. It feels like the stock servo agian. Can anyone help, should i do the saxton mod? Idk im confused it should have made a difference.[:@][:@][:@]

try tightening your servo saver

DS

why tighter? Isnt loose better. and that is the thing with the spring right by the servo, that you adjust by screw, just double checking.

Should have done the steering mod and filled your diffs. No matte rhow strong a servo you have the ST-1 needs the steering mod.

DS

ok thanks autoxman, now what does tightening the steering servo do? im goign to order the turnbuckles tonight 80mm ones, anything else i would need?

The Hedgehog

Some screws thats about it

Tighten that servo saver at least halfway up. It will turn with little force from the wheels if it's not tightened properly and you will lose most of your steering.

ericem

Did you set your end points for your steering lmao. Do you have the stock radio? There is a wheel you turn near throttle to make it steer more tight.

DS

yep did that

I bet if you tighten the servo saver, you will see a world of difference. I did on my Matrix.

My Feedback: (1)

you need to have a tighter servo saver because if you don't it doesn't translate the torque from the servo to the wheels it just kinda slips...i guess the best way to describe the effects would be like a slipper clutch if you loosen it up the car takes longer to accelrate hard or it might not even reach top speeds because the slipper is too loose now tighten it and the peformance for both accel and top end are increased...same difference with servo saver..checking that and epa's will go a long way but diff oils are a must and according to st-1 drivers the steering mod as well

DS

ok thanks guys

Ihad to put locktite on my servo saver ...had the same problem...what is this mod about? where to find info?

DS

i tightened my servo saver and now the steering will not turn, i think i over tightened it and now its stuck[:'(]. the servo saver is the thing where you tigtened the srew, and there a spring under it.. right... where the akerman plate sits on???I did the mod today and filled front and rear diffs, here is the link http://www.truggyracers.com/forum/in...howtopic=17753


might have to sign up, do it there is a great ttr thread

ericem

Yes but I think you were turning it the wrong direction is it touching the chassis now?? The bottom ring you were turning?

DS

no i was turning the screw, at the top. is that what you do??

sloppyG

doesn't the 5645 only have like 120 oz of torque?

DS

no it has 168

they can be optimistic with their ratings at times, but make sure you're feeding it as much voltage as you can

ericem

Ya are you running the stock receiver? The stock receiver has BEC and only sends 4.8V.

DS

hw do i get rid of bec, im running a 1400 pack

ericem

You need this you basically plug your power and servo into either your ch1 or ch2 and you don't use the actual place for connecting the battery on the receiver.

DS

how would i do that

The Hedgehog

He just told you.

Your really need to take a step back and build a kit or something LOL.

DS

no but if i plug my battery in ch1 or 2 were is my servo pluggoing then? I basically took this whole truggy apart by doing the diffs and steering mod. The diffs were easy. So i think i know the ins and outs no coment though lol
