When I set up my first FX-R on my old DX3, I had the same issue. I simply reversed the settings on my Tx just as you have done and had no troubles.
My second FX-R set up perfectly...I still don't know why that was.
Perhaps Kaetwo or Ty can chime in with something?
That's odd, as I've never seen or heard of that happening before. I've setup dozens of Tekins for local club members but it's pretty low in number compared to what the Tekin crew has delt with. One thing that I've noticed whenever I run into anything quirky is that resetting the ESC goes a long way. More on that below;
I was running an FXR in my GC2 with a 35T HH motor and my drag brake worked fine. I put the FXR in my Berg with 2 55T's and it was still good. Dropped 35T's in the Berg and my drag brake sucks. Any reason for this? Tried 45T's, too, but drag brake is still too weak. I ended up going to dual FXR's with 35T's and a 4pk, but would like to know the answer as to why this is? Other locals are having same issue.
I have not had that issue with my FXR and Berg and I change motors from 35T to 70T all the time. My gearing never changes though and the motors are in new condition. I would try resetting the ESC whenever you change out your motors. That's what I do. See below ;-)
Im also having the same problem. Works great with 55t very stong DB, then I got some 35t, No DB at all. So I got some 45ts, same thing no DB. Something the DB will work if I hold the throttle so the rig cant roll back but other most of the time the DB dosent work. I also reversed the endbell on the rear motor.
Here is how you reset the ESC.
1 - Reset your Radio to factory defaults. If your using a digital radio, use the reset feature, dont just bring the trims back to zero.
2 - With the radio off, turn on the ESC and hold down both buttons until the lights dance around, then release. Once the lights are stable, turn off the ESC. This will zero out the ESC.
3 - Now recalibrate the Radio to the ESC per the Tekin instructions.
4 - Download and install any ESC updates via the Hotlink (not necissary unless you want the latest updates) If you have the hotlink, I highly recommend doing this step.
5 - Reset your ESC. I like the following settings (Reverse/Forward, 3C Lipo Cutoff and 32 Drag Brake)
That should do it. Here is my Berg setup;
- It's HEAVY
- Rover Tires (which requires a higher drag brake)
- Dual 55x1 (Not hand wound but dyno'ed and tuned by me) Heavy spring on the Pos. and Med. on the Neg. I run a high silver brush, full face.
- 3C 2200 Lipo
- Hitec Digital Servo with a 6amp External BEC (Holmes BEC)
- Spektrum DX3R
I hope this helps.
