Kaetwo's Tekin FX-R Review...

I'd personally perfer wires instead of the posts because I was concerned about how much heat was getting absorbed from the soldering gun while waiting for the posts to get hot enough for the silver solder to flow. A wire would be really quick to solder and it could be easily insulated by shrink wrap. I know that the Tekin has a great drag brake, that's why I'm running them in my comp rig and the scaler. I wasted too much $$ last year with the novak garbage.

My comp rig weigns in at about 7lbs, that's with the double fatties full of bearings. I had a siuation last year where the course desended a really steep rock face, easily 50*, and the drag brake didn't hold the rig, but it did make the perfect, slow speed creep down the rock face. I couldn't have controlled it myself that well. My idea of the perfect drag brake would be more of a parking brake, all 4 tires would drag across the rocks as gravity pulls the rig towards the earth!

Interesting...if you're using a soldering "gun" those typically have insane heat and wattage ratings. You should be on and off in a matter of seconds at most.

I used an 80W Weller WES50 station at 800 degrees before I got my new Hakko 936 and I had the FX-R posts tinned and in about 2 seconds flat and wired with 12awg Noodle in about the same. Using a nice broad tip is key to retaining heat on the piece that you're soldering.

7 pounds at that type of descent angle explains the situation perfectly :shock: and I'm with you on the orange boxes...never again now that I own Tekin speedos.

If you have a general idea how to solder, the posts should barely get hot at all. You should be able to touch it seconds after soldering.
Also, its not silver solder that you use for wiring, you should be using 60/40 rosincore solder.
The solder post are one of my favorite things about the FXR, super simple, strong, reliable design.
PLEASE Tekin dont get ever get rid of the solder posts:)
 
I agree, I really like the post. Easy to solder and I can have the exact length on my wires. I like it way better than the wiring on my mamba max.
 
7lbs is a big rig and the motor might actually not be helping enough on it's own either. You can try stiffening up your spings to help a bit.

The solder posts should always be used. If you're not getting good flow soldering it might not be the wattage of your iron/gun but the tip size may not be sufficient to pass along that heat. A large tipped 40 watt+ iron is usually more than sufficient. Home Depot sells a 40 watt unger with a nice tip for $17.

I'm sure that my issue was that I used silver solder made for electronics, not the rosin core 60/40. I have a 140 watt Weller soldering gun, the one with headlights.
 
In order to program the FXR from the HotWire, does the FXR need to have first been initialized with the transmitter and receiver?

I took a new FXR out of the package and tried to set the brake, number of cells and F/R direction and the FXR never took any of the new settings.

And I could find nothing related to this anywhere throughout this thread or on RCC.

You don't have to calibrate the esc to the radio to change settings. However I'd like you to see what software version is shown in the "current version" window.

Randy have you guys tried a FXR-Pro with 35t's??? does the same issue exist??
I had a member on here pm me and tell me he switch from FX-R to FXR-pro and the smooth start like when he had 55t's was back...with no extra programming or tweaking..right out of the package it was better...I would gladly upgrade if this is the case???

Randy,

I will do that first thing in the mornng. I left my laptop with the Tekin software at work. Rats...

Although I did check to see if there were any software updates for the controller and it did not find any.

Ok guys,

I've going to release the new FXR software on the public.

Anyone looking to get this can email me for it. I do request again that you tell me where you live so I can point out any team drivers. Not giving me that info will only delay you getting the software.

This has an improvement to the throttle and full reverse upgrade for the B1R.

Please be patient as I know this is giong to be a lot of emailing.

I just got the 189 software from you a few weeks ago. Will the FXR software conflict with the 189 software?

Randy,

The current version I am showing in the little window on the HotWire GUI is .28. Again I tried an update and nothing happened.

Email sent for the latest software.

Randy-

E-mail sent to you. I hope I can get before this weekend as I have a comp on Saturday and Sunday. Thanks for getting this out to us."thumbsup"
 
I just downloaded the software to the FXR.

With a 35t the start up is much much smoother now.

Great work"thumbsup"
 
Email sent for upgrade.





So this is just an upgrade to the software. No programmable throttle curves or anything right?
