There isn't any problem with the VTX8 running a higher voltage servo -- as long as the servo can handle it. We list 7.0v in the advertisements, but the settings available will actually go up to 8.0v.

Oops...yea that's what I meant...sorry about that

I burnt a servo up this week by running the bec higher ); I never had a issue before but I guess this servo was a lil tired (:

+1 ... looking forward to seeing the new ads with the 8.0V voltage listed :nod:


Hey Nikos20002:

Any more news on VF 1/8 motor usage in truggy? Looks like we may be doing that next year. :nod:

I believe it was the Futaba Challenge race last fall where one of drivers finished second in truggy with the 1900kv test motor. I have been trying to do some research on what people use and gear for Truggy and to be honest with you -- its so all over the place, there doesn't seem to be any rhythm or reason for a lot of it. If you look at buggy - racers are on 4s between 1800kv and 2100kv. But truggy - is a different world it appears.

One more note on the higher voltage setting for the servo -- you also have to make sure you servo is designed to run at high voltage. I have seen some servos that list power and transit speeds for 7.4v -- but they are not marked as high voltage capable. All the speed control does is send the requested power to the servo -- if the servo has an issue, the servo couldn't handle the voltage for what ever reason.

Ya mine was totally user error. The servo was listed at I think 6.0 (:

I run the Hitect 7955TG, hitec confirmed it can take 7.4V so been using it at that setting. Been great.

For truggy motors, personally I think guys are overtorquing these things. Running a truggy can almost seems like overkill.

If the Viper could do a sensorless motor I would probably be dumb and try a castle 1520 motor on a truggy :) Having this motor pushing around a 1/5 scale savage without even getting warm and insane torque, can't imagine on a truggy.

As it sits right now though, I am VERY curious about a Viper Motor in a truggy ... VERY CURIOUS :)

I have been running my futaba at 8.0v it is wicked fast.

Can the vtx10r power a b44 with and 8.5 with no fan?

I ran one in a b44 with no fan with a 8.5 with no issues

Pretty sure Lee and Travis ran 5.5 or 6.5 (Nick can confirm) in 4wd with no fans :)

I run a 6.5 in an xb4 in tropical weather without a fan

Hi there,

I got a viper vtx10 speedo in a trade with the programing box and I keep getting an error when trying to link them up. Just wondering what I should be looking at or trying different to try and get this to work.

Make sure you press the power button for about 1 second to activate 'program mode' The green LED will turn Orange. After that, choose Link on the Progage / EZLink
