Kraton Took my Kraton exb for its first run

[JJay18]

I took it to the park so I could run it on black top and get my trim set and check motor temps. No fans on the motor yet and after several high speed passes as hot as the motor got was around 160f at the back running the 19t pinion. Only thing I was not too satisfied with was the servo which is a Powerhd-30kg that someone had recommended. In the grass it just does not have the power to get full steering and even on the blacktop it struggled some. I will prob go up to a 50kg or more. Power was great with the hobby wing 1650kv motor on 6s.

Thats a great servo.. I have it in my 1/10 6lb 3s senton , id keep it though for another rig and get something with more power!!

It's probably more the servo saver and not the servo. I suggest doing the C clip mod or buying adjustable servo saver.

Exactly this ^^ there are several threads about it. 35kg should be plenty to turn the wheels on the kraton if the steering were sending all the force to the wheels.

I'd look into shimming the servo saver spring.

Just did it to the wifes noto and it was like a totally different truck afterward. Might as well start doing it right out of the box

Idkkk.. whats your bec setting on, 6v or 7.4v!?

This is a good video where he showed how much torque you need. He has some test to back it up and he even did the servo saver mod.

7.4

I run 46kg in my K6 and Outcast. I agree, 30kg but too small.

That is a really highly recommended servo on the forum!!

Not saying this is what you're seeing but I do agree with the servo saver being too weak for those tires.
I have a raw500 and I thought I wasted my money but it turned out to be the servo saver.

I agree with others here: it's more than likely your servo saver rather than your servo.

I ordered the Protek hi torque servo. I will report back once its installed.

You should check out the Vitavon steering rack...best on the market IMHO. Will go real well with that Reef's 500.

I was looking to order that next. I already have the vitavon hubs and have their new diff cases on the way. Do you have the vitavon rack? Is the spring tension adjustable for the servo saver?

 

[JJay18]

I just checked the steering again. Servo saver was only ever so slightly opening when I was applying downward pressure on the front end. Under its own weight it will go full lock to full lock on a smooth floor but it sounds weak and slow. Once you lift it in the air its fast so I think I just need a more powerful servo. Cant wait to try out the Protek servo and the vitavon steering linkage. Maybe one of my buddies can use this powerhd servo.

I've got 4 of them...LOL. I'm to the point where its a MUST HAVE on the builds I do. Yes the spring tension is adjustable (you can twist it up or down with your thumb) and it stays solid. I think Basherqueen makes one with a grub screw to lock in spring tension but she only sells the servo saver side and not the whole rack like Vitavon. Its buttery smooth and makes the front end a lot stronger. Definite upgrade over stock.

Awesome! Cant wait to get it. Too bad they take about 3 weeks to get.

This is one nice rack!
