Kaetwo's Tekin FX-R Review...

[mann0mann]

Ty/Tekin,

Any more news on this update?

I'm curious...I'm using a DX3R and several FX-R's in different rigs. All with either 2s or 3s lipos and 35T or 45T motors.

I feel like I have what I would more describe as a "deadband" issue with my setups. It feels like I have to be considerably farther into the trigger to get response than what is comfortable. It's very noticable to me when comparing forward to reverse throttle positions in the trigger. Reverse will activate almost immediately into the throw of the trigger.

Is this new release addressing anything similar to what I'm seeing? The DX3r unfortunately has no deadband settings. in the radio.

The update for the throttle fix should be landing today and we will be able to release it shortly.

It has come down to 35T motors and 3S lipo where the throttle isn't as smooth, it feels ridiculously smooth with 55T and 2S. We're gonna have it fixed soon fellas!

how about 55t with standard 6pack stick batts?

 

[Tekin Prez]

Yes we are looking closely at all the super slow crawl issues and feel.

I have to admit on 3s and a 35T it is a little jumpy and the difference between fwd and reverse is more obvious.

Listening, learning and improving....

How do I get the update and will I need to have the computer link to do it? I would like to get this done as soon as possible.

 

[Ty@Tekin]

The update will be available on the web and yes you will need the HotWire PC Link. Everytime you start up the software it goes and checks for any updates if you have an internet connection at the time.

Do you know when exactly the update for crawling will be available. Just ordered the Hotwire link and would love to get the crawler slowed down for the wife.

Not completely happy with our first effort. It is better, but not as good as we think we can do. Give us a little time to do our job and I think you will be happy. May have to be a special software for crawlers which is a a little deeper and takes longer. So with development, debug and testing maybe in a couple of weeks we will have a beta to pass around.

Thanks for the update teamtekin! Good to hear this awesome ESC is getting better and better.

 

[SULFUR]

I CANT WAIT!!!!! This will make the FXR THE BEST ESC for crawlin ever

 

[goldmember]

I've read through this thread and honestly it's what sold me on this ESC. In fact I bought two. One for my SCX10 and one from my AX10.

Kaetwo or anyone else who has honest experience with this unit. Below are what I changed my FXR settings too for my AX10. I am going to be running 3s lipo and figured this would be a good baseline.

After reading through Kaetwo's configuration I figured I'd start with those settings as a baseline and adjust from there. As weight, course conditions, etc are all variables.

One other question...do I live the current limit and push control off?

 

[kaetwo]

Goldmember, I appreciate the comments and I'm glad that this thread has helped out. I can't get enough of the Tekin products :lol:

Your settings for Push Control and Current Limit's are great in the Off position. I have never found that they produce much of a result in the crawling areana with my personal rigs. However with on-road racing it does have it's place. For example;

Push-Control - I find that this works especially well with stock racing, where you need to maintain speed in the corners. With stock motors these days they produce so much torque that when you let off the throttle and the motor stops receiving power that it can cause you to spin out. This is most notable on a loose track, especially with on-road racing. Push-Control will help you dial your return to neutral setting so that it's not so abrupt.

Current Limits - This is useful for again stock racing. It allows you to set how much current is deliverd in response during acceleration, which is a big advantange on a high bit track. It will allow you to accelerate with more authority out of the corners and get a small edge on those without it. In reverse it also allows you to tune down the power laid down on a loose track, preventing you from spining out.

Now the question is, do these features have there place in crawling? I think that they do for some drivers and rigs, but for myself I do not use them.

Does that help?

It does. My worry was leaving the two off. I know the other settings are just baselines that I will tweak after some time running my rigs.

This is the first time I've ever tinkered with an ESC. I bought my first axial used last year with a Novak goat. Now I'm building and SWX with the usual parts and adding a Tekin.

I was just trying to make sure I was in the ball park. Seem like I am. "thumbsup"

does the deadband an issue across the board or is it just being found an issue with lipos and "jumpier" motors? i'm getting one and will be using an 8 pack and a 55t motor.

There is really no issue per se. What you will see is a small lurch from stop to rolling when running a 35x1 or so motor with high voltage. If you running a 55 you should be great, but it's enough of a gap that Tekin want's to address the problem. I solved it by changing from twin 35x1's to twin 45x1 and it's smooth as glass. You can also solve it with the following;

- Softer brush springs
- Lower gearing
- Higher wind motor
- Harder brushes

I hope that helps.

Thanks kaetwo!!! between this thread and speaking with mann0mann directly, i'm stoked about tekin. to think i almost went with another brand, and thanks mike!!!

 

[mann0mann]

And to be fair, my comment regarding "deadband" I feel to degree is the radio as well.

I wouldn't say any of my rigs are jumpy in any way...there just is a measurable difference between when forward throttle begins to initiate and when reverse initiates from a neutral position.

Neutral to reverse with My DX3R "feels" better to me...

Neutral to forward feels like there is much more trigger position to initiate movement.

I still wouldn't trade my FX-R(s) for any other ESC available right now. It's a great ESC and will only get better as we see more software development."thumbsup"

I'd love to get the "first effort" beta you are unhappy with.

If it's a little better, then it's still better than what I have. And I'd rather have something that is only a little better now while I wait a few weeks for perfection.

Just a thought."thumbsup"

Killer info...I'm looking at motors and batts right now (HH P-94 45T) and I'm debating between going with his 2S or 3S Lipo's as well. This thread has been more than helpful along the way as I tweak and re-configure.

Kudos to Tekin as well for staying in the game and listening to the drivers here. They're certainly striving to make the best products possible and not simply resting on their laurels. "thumbsup"

 

[Randy P]

We're not happy with and are working on a better solution. No sense in hadning it to you when we know you're not going to be happy with it, we weren't.

It's going to be a software update and we're taking the time to make it crawler specific.

We apprecaite the support. This is why we strtive to make improvements. We listen to what you the customers are saying and go to work. Best part is when we do make the improvement, all you have to do is download it and go(for free!).

 

[shierkahn]

I just got mine in the mail today Got it wired up which took me a little bit of time but, that's ok....I just wanted to make double sure I had everything right. I'm thinking the set-up part will take me a little time , as I've never done it before. Still need to get me the Hotwire so I can get the current and future updates and features of this big little ESC.

Now I just need my batteries to get here.

Thanks guys for the great product and for this awesome review"thumbsup", Chris
