The VSE motor is no longer in production

I would say to un-install your update software and re-install the software from the Viper website ( http://viper-rc.com/viper_pclink.zip )

If that doesn't work, try a different USB cable

You should get a light on the PC Link even if you do not have the Viper software open

I will try the reinstall. I only have the one link cable so I can't try another. It does flash red when plugged in.

Ok, connect the PC-Link to your PC, and let it power up

Then open the Viper Software. You should be able to see USB under the port list, even without being connected to a ESC

Jamie, when you plug the Viper PC Link into the computer do you see the red light come on? I am not in front of my computer, but I remember there being a red light showing the USB connection is "live".

Nope. Still only seeing COM1 and COM3. I'm really starting to get frustrated.

Ya Nick, I get the flashing red light. Really getting

Any other thoughts guys? Don't tell me this has never happened before....lol I was hoping it was something you had already solved before and it would be a quick fix....lol

Maybe go into control panel, open device manager, and see if you have any errors in your USB devices. If so, try deleting and updating the driver.

I dunno, on mine as soon as I plug in the Pc-Link I get a "USB0" under the ports.

copperhead in stock @ amain http://www.amainhobbies.com/product_...r-Combo-5150kV

Pardon my ignorance...
In theory, given the same battery and gearing (2s, in this case) a lower KV motor would net a smoother throttle response and more top end vs a higher KV which would net a better bottom, with limited top end, perhaps even a shorter powerband... But the higher KV motor would likely generate more heat. < Is this thinking correct?

I have a friend who is looking for a new system and might be interested in the CopperHead, Thx to the great price point.

What model Copperhead would Viper recomend for a SCTE?

I run the R45 and has pushed my SCTE easily. Nothing wrong with the R51 either, it's really fast.

I currently run a Noval 550 4.5t. What is most comparable to that. I am a racer not a basher.

R51 would be a good choice then. You run on bigger track?

i ran the R45 this weekend and i was able to gear that thing up to 17T and it was very fast. 16T would probably be more safe as i was running outdoors in about 60 degree ambients.

A small indoor track during the winter and a big 1/8 scale track in the summer.
