Kaetwo's Tekin FX-R Review...
- Thread starter kaetwo

I just thought about something...this thread is great, in terms of the ESC, but nothing has been said about the Tekin 55t motor. What do you guys think about it? What about the hand-wound "pro" version? Are they any better than, say, the Novak 55t motor, Venom Fireball 55t, Trinity Epic 55t, Axial 55t, or the Integy Matrix & Matrix Pro 55t motors? Or are all the 55t motors essentially the same?
I will be up front and honest too you on this. Most 55t motors are the same. You may have one with an Epic endbell and another with a Yokomo endbell, but there for the most part the same. When you get into hand wound motors, you start getting into a more efficient/overall better performing motor and it's what I try to use in all applications (crawling, racing, etc...).
Now back to the statement "Most". Some motors are tweaked to perform better. For example;
- Hood alignment
- Re-Brushed (Higher silver content, brush cuts, etc..)
- Balancing the Arm
- Spring tuning
And the list goes on and on. I have used motors that simple feel better, due to this tuning. I personally prefer to tune my own motors so I buy the Tekin 55x1 Pro's and play with brushes, springs etc.. for the application that I'm looking for.
Long story short, if I buy a motor, I always buy from Tekin. They have an incredible eye for detail and customer service and that's good enough for me to buy the rest of there products ;-)

Nail, meet hammer!
The only notable difference between machine wound motors is the Epic, it has stronger magnets than the rest.

Again, thanks for the excellent information, you guys rock! I'll just stick with the Tekkin 55t hand-wound "pro" motor.
While we are on motors...can someone further explain the single, double, triple, and quadruple windings? I know that a single has a "punchier" power-band, and a "quad" has a "smoother" power-band, but I have always wondered about the details of why that is. Any help will be greatlyu appreciated!

Quad winds resist the inrush of current, therefore power delivery is smoother. For crawling a single wind is best.
The Tekin handound is a great motor.

fx-r problem?
well so i had my fx-r for a couple of days now i just installed the cc bec, but every time i flip my truck nthe esc resets itself.
not so comp friendly since i can get the truck back on its wheels cause the thing turns off, any clue whats causing this?????
i checked for loos wires but everything is fine, at this point im just tired and feel like i have brainfarts everytime i sit down and try to figure out the problem.
i can only hope for your help, thanks

How is your switch mounted? It could be mounted in such a way that when the truck lands on its lid, it jolts the switch into the off position, or moves the switch enough to reset the ESC. My friend had his switch installed where "on" was towards the back of the truck, and when he ran into something, it jolted the switch forward and turned it off. I simply turned the switch around, so that "on" was towards the front of the truck, and when he hits something, it can only jolt it more forwards, which is still on.
Check your switch position, and change it and see what happens. Also, you can make a little lexan plate that locks the switch in the "on" position, yet bends up with your finger when you want to turn it off.

I recently purchased a fxr-pro and am really happy with the unit. My 2.2 berg crawler weighs in at 8lbs. My previous esc's drag brake could not handle the weight to give me a controllable drag brake. I have the tekin set at 35 and it is awesome.
I do have a question on the trottle response as to the low end smoothness, I cannot get a smooth 0 to .1 mph start. When I adjusted the expo on my raido it just delays the start req more throttle pull. After reading above I noted the comments to try adjusting the epa's on the trottle. I will try that next.
I may try reseting the radio to default and the esc to default and see if that makes a difference. I just installed the new esc without doing anything to the radio (DX3R).
My main question is the upgrades for the hotwire, I read in the forums on the tekin website before coming here (silly mistake) that Tekin is working on some update downloads that would address the throttle adjustment issues but there are no follow-up post that this has been done.
I just ordered a hotwire and was curious if the updates are available yet?

Nope... not yet... after the weekend here I'll sent Tekin an email and ask what the hold up is. It has definitely been longer than we thought it would be.
What motors do you run?
What is happening here is that if you take a 55x1 motor for example and rotate the pinion shaft you will notice that there is a magnetic cogging that needs to be overcome. Now double the effect on a berg (2 motors). That lurch or lack of "low end smoothness" is due to the dual motors needing to overcome that initial resistance and this is displayed in the form of a jumpy start. I tested this in my touring car with an FX-R and it was smooth as butter and my Axial is smooth too, but the lathe motors require a bit more to overcome this effect. Now when you move down in winds (say to a 35x1) the startups on those are much worse than say a 45x1. While this is a totally different cause, the effect is the same and increases the overall lack of the "low end smoothness" issue.
Does that make sense?

i had the same problem with my fx/r, i didnt set everything to 100 percent and had that lurching effect. reset the radio to 100 % and reset the esc , after the esc is reprogramed to your 100% settings then lower them to get the smooth starts. btw i am running 19 turn drift motors ...... very happy :ror:"thumbsup"

Kaetwo, I run two of those high dollar 55t Integy slave motors :lol:
and I understand how you explained the lurching effect of running two motors.
I received my hotwire yesterday. Everything seems to be set correctly for the esc and my radio settings are at 100% for the throttle.
The throttle response is smooth, but it still cannot make it creep forward a 1/4" or 1/2". When I try to lightly move my crawler it moves an 1-1/2" minimum. No matter how light I am on the trigger.
I tried turning down the travel settings on the throttle and that just limits the top end.
I tried adjusting the expo and that only increases the amount you have to move the trigger to get the throttle to engage.
Diffinately a problem when trying to inch past a gate..
I plan on going on the rocks today to test and play. It may feel different on the rocks as compared to my work bench.
Would a better motor help? Is that what is causing this?
thanks for your responses
and get ready for a happy new year !!

The rest of the story...
Field test on the rocks the control is alot smoother and will allow me to creep in small increments, this is due to the courseness of the rocks. A little up hill and I have complete control, if downhill it wants to move more than I like...
and the rest of the story cont...
A friend showed up and as we discussed the fine tuning. He said to try turning the endpoints up to 150 instead 100 and then to rebind the radio to the esc... rebind being the key word... ooops. Had I forgotten a step earlier??
So with a magic push and hold of the button on the fxr... viola..
much much smoother response now !!! And I was able to use the expo to soften up the trigger for the initial forward motion.
All worked well on the rocks, much better now ;-)

Awsome to hear!!!
I will have to try that trick myself as I run into the same issue with my 35t motors. My 45t motors however worked great with the same setup as my 35t. This was mainly due to the lower cog strength ;-)
Well done and thanks for sharing the details "thumbsup"
I just got a set of 35t motors from Tekin and love them ;-) I'm going to get a few 45t to test out but so far my initial finding is very positive and will be running only the Tekin motors. They treat me good and Tekins a great company to support.
Are they better than anything else out there? No. There basically all the same motors, it's just who do you like to support.
Does that help?

Sure does... are they going to have the standard and pro-wound versions? When will the combos be available? I'm thinking a 45t Combo would really be what I want.
Good question!
I haven't been told if other combo's will be available. I'll see if I can round up some details ;-)
