Tekin FXR issues

the lever upward for 0.5 seconds to make the servo operate normally (NOR). The arrow will
indicate the condition of the servo (normal or reversed).
4. Use the SELECT key to display other channels to be reversed.

okay thanks now we got that problem fixed. so now just the BEC

thanks for the reply ty. ya ive seen it both way in the bec wiring thread but wasnt sure if one way is "better" then the other.

i fixed that problem. so now when i push to go forward it goes forward with the LEDs going Left to Right

so you recommend running the exbec threw the rx and not directly to the servo? im setting up my fxr right now too and would like to have to only do it once. thanks!!

Nother option -- I run a Hitec 7954 with 2S and the servo box said it's 2s safe. So I called Hitec tech support and he said no need for a bec on their popular 79xx series if you run 2S. Just hook the servo power straight to the battery plug. And of course the signal wire (only) to RX/Ch1. So for this you leave all three esc wires connected in order to power the RX.

Ok now when the bec is wired to the battery does the yellow light come on? Its under the shrink wrap but you should still be able to see it shine through.

is it suppose to light up when it's plugged in or when i plug it into the receiver?

lets say if i just hook it up to the battery and ot plug it in. it's suppose to light up?

also looks to me in this picrure you don't have the ext bec hooked up so yes the servo is pulling the power away and makin you esc glitch out

keep in mind when you run the bec and it is all hooked up the right way and all is good your bec will be constantly powered until you unplug the battery even tho you switch off power to the fxr

and as said above i would have a serious look into those solder joints

yes the bec should light up if you hook it up to the battery ....there is no switch for the bec so connect and its on

this in turn powers the reciever when plugged in and that feed more amperage to the steering servo that is why you pull the red wire from the esc plug

if you want full power to the servo you can reprogram the bec and run direct to servo to achieve the full output from the bec thus leaving the esc's bec to power the reciever

are you confused yet ......hope not

[ZackMicF]

i just took a better pic. let me load it up real quick

[ZackMicF]

and i cleaned up my messy solder job

[ZackMicF]

sorry about my heat shrink mess too. but the BEC is not plugged into the receiver

is it okay were i have BEC wired to for power? straight off the FXR's power post?

[scorpion_ax]

here is a clean picture so to fully understand bec wiring direct to the servo for full power capabilities providing you HAVE a servo that can handle a voltage increase for more torque

[scorpion_ax]

ok so those pics look good so now you should be plugging that bec into a spare socket in the reciever ....try maybe the bind socket and remember to pull the red lead from the fxr BEFORE plugging in the bec and battery

remember the bec is going to have constant power now that it is direct to the battery so the fxr switch will NOT control power to it

that should fix you up if the radio and fxr is all calibrated and linked good now

[scorpion_ax]

here is another referance pic for you hope this helps out

disregard where its says the battery voltages in the picture that is just a voltage rating that the castle bec is rated for no the FXR

[ZackMicF]

is there any way to test to make sure my BEC is working right?

[AreCee]

Check it with a voltmeter at the receiver plug end. It should read the volts you set it at (if it's a CC BEC set by CC Link). If you didn't set the output voltage then you should see 5 or 6 volts at the plug.

[ZackMicF]

i think mines broke or something. i'll just have to buy a new one tomoro. other then that my ESC is working fine long as i don't turn real hard real past repeatively

[scorpion_ax]

you could always go direct to the servo to see if there is an issue with the bec ....... on another note have you hooked it up to the castle link to try and program it this will tell you if the bec is hooped too. you wont be able to connect to it if it is in fact no good .....

i have had a few issues with the castle bec's fried three of them in a week so i stepped up to heyok's no brainer bec custom built to 7.4 volts out and has never failed me no
his bec is complete plug and play and works seamlessly direct to servo with no wiring alterations

[SMR 510RR]

All those solder joints probably arent helping...Looks like you have 2 per wire on the output?!?!

You can buy some servo plugs and a pair of crimpers and crimp on new connectors after trimming the wires down to your desired length.

just my 2 cents this is the better way to do it because you dont loose your lipo cutoff like if you hook the exbec to the reciever
