You have to push and hold the button for a few seconds until the orange an red lights light up. Then you can link up.

I have a new VTX10 esc and viper motor. Occasionally it shuts off. Usually after a jump. I have checked all the wiring and it looks OK. I checked the sensor wire and even unplugged both ends and plugged back in, but it did it again a couple times last night. I still have steering when this happens and after a few seconds it will take off fine. Nothing is hot either and I know the batteries are good. Any ideas???

I just put in a Hitech 7955TG recently in my SCT410. It makes a little noise while just setting there. Have you had that issue??

sure, your esc is rebooting. I had the same issue a while back. My cause was a bad connection at one of the bullets going to the battery. But if anything on the power side goes wrong, it will reboot. Make sure the caps are soldered on well and you can try you put some servo tape under the cap to keep it from bouncing.

My Cap is secured to chasis with tape. I will double check my battery connections, etc. Cap came already soldered on. I would assume that is good. I also use 2 different battery types. One with bullets and deans and one with just deans. I'll have to pay attention to see if it is hapenning to one and not the other.

ok, I was unsure if you had the BE or orange esc. Anyway, my wire going into the 4mm bullet was broken 90% the way through. I replaced the wire and the issue went away. Others have has the same issues with loose caps or caps soldered incorrectly. If all of the wires and joins are good, then you can always warranty it.

I went down 2 teeth when I used a tekin 1900kv buggy motor for my truggy. Now I went from an mbx6 to a converted tamiya 801xt but F/R diffs are almost the same ratio as the Mugens.

Not much activity on the VTX8 thread so I thought I'd post over here.


I'm looking for some setup suggestions for SC 4x4 on a dusty hard-pack outdoor track. Right now I'm messing around with a mix of VTX8 and 4PL settings and I'm over-complicating things. Basically I want to soften the initial hit of the throttle to help maintain traction out of corners, but still need enough pop on a fairly short run-up to clear some doubles on a 1/8 buggy-oriented outdoor track. Running a VTX8-Pro4 HD 4300-16t in a Hyper 10SC 4x4. Way over-powered, but man its fast when hooked up and comes off the track nice and cool.

Any suggestions for forward power/punch/acceleration timing/acceleration RPM window combos?

Thanks, I will give that a try when I get home. Thought I may have been doing something incorrectly. Our 17.5 2wd buggy class allows use currently to use boost, and I tried the 17.5 and 13.5 boost that was programmed into the speedo and its still a bit much so I want to de-tune a bit more. This is my first speedo in over 5 years that isn't a tekin so im giving it a try. So far if the EZ link works, im thinking I will be happy.

Sounds like a connection issue with the lipo. I stopped usuing Deans for this reason. If the system notices a voltage drop it will shut down and reboot. When this happens you will have steering but no throttle untill it finishes booting up. Change your connectors and see if it helps.

Just answered you on the VTX8 thread -- but Punch, that will be the biggest thing to work with. More details on the other thread (to avoid typing it all again). Nick/Viper

With the connection issue - even double check if your wires have heat shrink on them.

Famous story (for me atleast) - just talked a new driver into using our stuff, at a race with him helping him get a unit installed in his car - no power, can't believe. 2nd unit, no power - no way, 3rd unit - no power, this is crazy. Then he thinks maybe it my receiver - replaces it - no power. New servo, no power. We can't believe this isn't working - now practice is almost over for the night -- we agree to put in his old speed control - he goes to plug it in -- wire comes off the deans plug on his battery - it was loose the hole time the shrink wrap was holding on enough to make it look connected.

Thanks Nick. I'm liking this Orange and Black scheme.

Talk about having a bad day.....

I see on face book vipers having a sale but i can't get in to some off the
area's to order like the ESC part.
