Kaetwo's Tekin FX-R Review...

[Rockcrawler]

"Rockcrawler"

Tekin should pick you up as a team driver if they have not already?!?!???
you are always in this thread offering help! and tech advice!
great job bud! members like you make forums VERY helpful!8)

:lol::lol
Thanks 53 willys. I am "decent" when it comes to electronics. I just really like these Tekin FXR's and try to help out when I can. As much time as I spent playing with mine, I should know just about everything about them. :lol:

 

[Rockcrawler]

My CC BEC is going through the receiver. You think that could be causing the issue?

Sounds like your doing everything right. I do have my BEC running straight to the servo though.

Can you try to just put the red wire back in on the FXR and disconnect the BEC just to see if it has drag brake? Thats the only other thing that I could see unless it was bad from the factory..........

The FXR flashing from led 4 to the other led's is the onboard temp indication, it's normal!

I too would like you to pull the CC bec and try going direct with the fxr's just to test the drag brake.

So when I do this I should unhook one of the ESC's red wire correct. I dont want both plugged into the receiver right. That would make 2 sources of power input correct ?? I'll try it tonight and post what happens. I'll try it with one ESC and with both ESC's. I wonder if it has something to do with the construction of the motors? So weired, I can install my 55T's and not change a thing and it works perfect, lol.

He is running the esc's in seperate channels. I know it is bugging the heck out of him trying to figure out what is wrong.

i totally understand the feeling:x..i was running dual goats but have been srtruggling with very inconsistant performance out of them..sometimes full drag brake and then sometimes zero drag brake..since my dig is based on drag brake it was a nightmare..always seemed to work fine at home but hit the rocks on comp day and well.. anyway i switched to the tekins and much happier now..you might have to contact tekin if you havent already they are pretty good..hope you get it figured out it a bummer for sure when things dont do what they are supposed to

ahh i c tekin is on board now..good

Since I put mine on 3S I started noticing a small bit of glitch after using it for a bit, also the FXR was getting EXTREMELY hot. At the time I put it on 3S I also upgraded my steering servo to a Hitec 300oz servo, I assume its taking to much umph through the ESC so I purchased a BEC that controls the power for the steering not even allowing it to go through the ESC.

I have not hooked it up yet, but I assume this will take away quite a bit of the heat and get rid of the little glitchyness that I have been experiencing. "thumbsup" $29 for a custom BEC shipped.

Well I took out the CC BEC and used the BEC from the ESC and the same thing still happens. Sometimes the DB will hold then I steer and it rolls back, most of the time the DB wont work until I hold the throttle on a little bit then it seems to hold until I steer. Maybe I will make a video of it this weekend. I just dont under stand how it could be any radio or ESC settings when it works perfect with 55T motors. I just cant go back to those slow 55T motors. You need more wheel speed then that. Im just about ready to say !@#$# it and sell the berg. I'll have the new Losi in hand soon. Maybe I'll ship it to tekin and they can play with it, lol

 

[LittleDave]

Can you run this EEC on NiMh batteries? I don't see anywhere on the description it saying it was capable of it. Also, what's the difference between the FXR and the FXR-pro. I'm sure this has already been covered but let's be realistic, there's 32 pages to this thread.

 

[vonclod]

i think the fxr pro has more or maybee double the fet,s or something like.. smoother, and handles more power..from what i,ve read anyway

have you tried it with a 2s pack yet?

 

[THAT1GUY]

have you tried it with a 2s pack yet?

No I didn't. I tried it with just one ESC and the same happened. I giving up until the weekend. Going to play Forza 2 for the next couple days, I need a break, lol

With the BEC disconnected, you dont need to use the steering. You could actually just leave the steering servo disconnected. We just want to see if the DB works without the BEC connected. If it does work, I would think you need to run the BEC directly to the servo and bypass the receiver all together.

 

[THAT1GUY]

Yup I tried it with out the steering servo too. And just one esc. Then tried it with both esc's and but only one having the power wire going to the receiver. Then I switched witch esc was giving power to the receiver. I think I might just have to give up. Maybe at our next local comp I will swap 35T with a guy that is running the same set-up and its working perfect. I also ordered Purple motor springs that have more tension too.

I am not going to say that its not the motor, but I would think that you just would not get "as much" drag brake as some of the better motors. I got rid of my integys or I would throw them and to test it for you.

Thanks for all the help and info from everybody on here, its nice having a place to go for help.
I will make a video of it this weekend. Maybe that will shine some light onto it. The 35T's I ordered from Team Brood where suppose to be High DB motor's too. I just wish somebody else with the same set-up lived closer to me. I have a comp in 2 weeks. I will do some more testing then.

my buddy is having an issue with his fxr

hes running a berg a hitec 7985 servo, handwound 45t motors i beleive and hes got the cc bec running through receiver with red wire disconnected, and the issue is while turning even on smooth surface the esc will beep and then the lights go solid, and then you have to shut it off and turn it back on and it works again for a few minutes and then does it again, i noticed though that jus before it beeps and shuts down it seems like it is loosing power the lights dim weird. cannot figure out whats with it, we thought maybe the bec or servo but now might be thinkin its the esc.

any help would be awesome thanks.

Which red wire does he have disconnected?

I would run the BEC straight to the servo, the spektrum receivers just dont like the voltage.......

the red one on the bec, see the thing is he has never had a problem than he changed the servo mount back to the original one and it has never been the same but we went through the whole truck to figure out whats going on, but yeah never had problem before so thats why we cant figure it out, its really messed

If he disconnected the red wire from the bec, the bec isnt working. ;-) Thats why I asked. You disconnect the red wire from the tekin so that it isnt also trying to power the receiver. "thumbsup"

this is what i just did, thanks for the help, it seems to be alright so far"thumbsup""thumbsup"
