Yup, you are right. I'm sure these guys will get it fixed. If you don't hear back in the next day, Shoot Nick a PM

what happens when you are geared 24/81... If I'm correct you said this is with an 8.5T?

I know I typically geared my D3.5 based motors 23 or 24 /81. The other guys at the track running Reedy, LRP, Orion.... everyone is in the 23/24 range. I haven't tried the Viper motors but I know my buddy Fred is running them in his Durangos and they share the same gear ratio....maybe you are over revving the motor?

Rule of thumb that was explained to me is:
speedo hot = under geared
motor hot = over geared

Obviously this isn't gospel, but it it could help. I would try 24/81... run it a few minutes of clean hard laps and see what the temp is. If it's not too high, run it a bit longer.


Oh one last thought, he did run cooler when he upgraded his firmware to the newest version.

Is the vtx10 BLACK EDITION legal in aarmcc races?

We follow ROAR/BRCA/EFRA lists, so if it's on there, it's legal for us.

It says that the vtx10 a19 is legal. Does that mean the black edition is not legal?

Viper has submitted the Black Edition ESCs with a55 Firmware for ROAR approval months ago, and have been told that they are approved, but ROAR has not updated the approval list

Looking at the settings / gearing I think you are under-geared almost 15%

Your roll-out would be a 1.08"

Many of the AE drivers run 7.5 motors and run either 22/78 or 22/81, and on my B4 with a VST8.5 / VTX10R-BE I am running 23/81. My roll out is at 1.18"

I would suggest going up at least one tooth, turn down the brake freq to 2500 or 4000hz, and turn the motor back to stock timing. Set the end point at 80% on the throttle and start testing there. Again, set the motor and esc temp settings ESC 170 and motor 200.

Unfortunately, we are at the mercy of others when it comes to updating the on-line information

my esc just quit on me, im in the market for a replacement.

viper looks good and the price is apealing to me. I see the vxt10 at amain for 155.00 and the vxt1 for 167.00

1. is the vxt10 the older version of the vxt10r?
2. is there a big difference between the two? (10/10r) is the vxt10 outdated will I be sorry i got it?
3. maybe the vxt1 would be best for the price? (i race stock buggy may go mod in future)

any advice would be great, they all seem the same to me

The VTX10R is for faster motors, other then that they are the same. I run a VTX10 in all my 2wd stuff and the 10R in my 4wd buggy. The VTX10 is good down to a 6.5 turn motor

so howabout the vxt10 VS. the vxt1?

im sorry for these q's im sure its been gone over before but im not finding it with the "search" and I really dont want to read all the pages on my small screen on my phone. haha

thanks guys apprecieated

I'm not familiar with the VTX1, sorry

Grab the black edition. You'll love it. Just get the standard, not the R (unless you are going to run it in 4wd too).

If you get another, you can get the 'lite' version, which doesn't come with the ProGauge. Since you have one, you really don't need a second.

oh and the VTX1 is the more know for being a beast of a 12th scale speed control from what I read. It can be used in offroad, but I think the one I linked previously is the proper choice over that for your application.

is the progauge mandatory or? no usb interface or software? or can you program by pushing buttons?

im just trying to save $$ because this is going to be an "unscheduled purchase" haha
thanks
