Alright lets try this again guys....

[Lentsnh2012]

Alright, I figured out the Savox servo problem... It went bad totally. I voided the warranty because the original wire lead was too short for my Wraith. So...


I put in my Solar D772 servo, 15 minutes in and it started to tick JUST like my Savox. Gears are fine this time but my servo is done. It gets stuck and it just wont turn the tires. I soldered the BEC back and it still does it ALONG with my Novak 8.5T brushless/ XBR Sport ESC cogging or glitching at full throttle. The BEC is on, the red wire has been unconnected from the plug for the receiver. I'm running out of ideas. I love this Novak system but if it keeps doing this, I may have to go back to my brushed setup.


HELP!

[TRUBLE]

you said the red wire was disconnected from the plug....did you disconnect the one from the bec or your esc?
what vehicle are you running?

Correct, I unplug the red wire from the ESC. I'm running this system in my Wraith. Still using stock diff gearing with an 87/17 and the stock sticky RipSaws.

i have seen alot of peolpe having problems using servos that can turn the weight of the wraith...i am using a hitec 7950 on a bec at 6v and i havet had a problem...it has 403oz of torque at 6v. a buddy of mine had the same problem until i bought his wraith and put a better srevo in it...maybe this helps

I appreciate the help man! Any advice/help is better than none!

I did have a Savox SA-1231SG that got completely ruined by this Novak system. It ran fantastic when I had the Axial 27T and AE-2 ESC. I know I should keep a BEC in the Wraith but then it messes with my throttle control... it sucks. I like to WOOPOW the Wraith up rock obstacles.

i hear ya man...what kind of radio are you using? have you set your throttle limits on your esc?

I'm using a Futaba 3PL with a R2004GF Receiver.

See this is where it gets weird, when it doesn't have a BEC hooked up it drives beyond perfectly. Everything is as smooth as you could ask for. You now made me wonder if the BEC is messing with the ESC on a throttle output or sensitivity.

what is the bec plugged into on your reciever?

I have it set up:

CH1 Steering
CH2 Throttle ESC (red wire removed from plug)
CH3 BEC
CH4 AUX for my LEDs.


Steering on radio : 120% left and right
Throttle on radio: 120% forward and reverse

Plug is plugged in correctly as well.

is the 3rd channel the bind channel? set the limits on your servo....pick it off the ground and turn and hold the steering both ways and back off the percentage when the servo stops humming

[TrickyRicky]

Try powering the servo only with the BEC and the rx with the ESC. I had some of the same problems when I ran the BEC through the RX

I'm not totally sure on the binding channel, all companies are different. 120% was the throw of my Savox and it was perfect. When I hold it in the air and grab the wheel it'll tick and click like it does when its on its own weight.

How would I go about doing that? Using a Y connector? That sounds like that could be the solution!

[TRUBLE]

The way I have seen it done was you would cut the positive and negative wire on both the servo and esc. Wire the positive to positive and negative to negative and then plug the signal wire from the bec and servo into the receiver.

[TrickyRicky]

The signal wire from the BEC is for programing only. Red to red black to black from BEC to servo. Run the signal wire only from servo to rx. plug the ESC to rx normally with all three wires dont plug the (signal ) wire from thebec into anything.

It sounds like you maxed out your end points just for the sake of doing so.

If you calibrate your radio and esc properly, you shouldn't need to mess with throttle end points, and bumping them up to 120% does nothing.

Blindly maxing out your steering end points is a good way to kill a servo. Chances are the it is still trying to push long after the steering assembly has run out of travel.

Also, look into servo extensions or Y's when hooking up becs like that. It'll save you from voiding the warranty by cutting and soldering.

X2 steering end points need to be properly set or you will burn up any servo.

Maybe I need to recalibrate my ESC with the BEC hooked up? It came from a Losi truggy and I just put it into the Wraith with out making any changes.

I'll try to find some Y harnesses for the BEC and servo. It'll definitely make me feel better instead of cutting through the servo and BEC harnesses.


Ever since I put in that Nocak system I've been ruining servos.. When I had the 27T Axial motor and AE-2 system w/ BEC in the Wraith, it was perfect. How would I properly setup my steering end points?


Thanks guys for the help!

[Duuuuuuuude]

Hook it all up like you will be using it, reset your throttle end points to 100%, then calibrate. Your esc should show confirmation of full throttle and full brake/reverse.

For steering: reset your end point to 50% each way, turn the wheel to the right, run the end point up until the wheels on the rig hit their physical stops, and no further. Turn the wheel to the right and do it again. The end points may not be the same %, but that is fine. Its just a number.
