Will the fan on a vtx10r come on with power or by heat

should come on when you turn the power on with the newer software programs.

Yep, should spin up about a second after you turn it on with A64 software.

the fan doesnt come on at all when plugged into esc but where the capacitor is there is a plug but it is over 5 volts so i dont want to ruin the fan i just got this back from viper saturday and it says a64 software

What kind of fan is it? Is it designed for hobby use?

5 volts shouldn't hurt the fan. Most RC fans are in the 5 volt range.

It's the viper fan set made for the vtx10r

The other place is coming straight feom the battery where the capacitor is solder on

I will only run the fan outdoors this summer I didn't know if there was disabled or not in a program. I hope to put a voltmeter on it to see if not May wire up through receiver

Is it brand new or older? It should come on after the unit completes the start up program. PM me with more information and if you have more detailed questions. Nick/Viper

That VF4 is a 540 can???

Had a good night of racing with my Viper powered B5 in 17.5. Finished a few seconds behind viper team driver Bert Jones

I believe it is a 550 4 pole can.

looks like a 540 4 pole can.


nikos: can you give any info on how you guys finalized on can design? by that I mean, were there benefits you saw to a smooth can versus say the design of the 1/10 scale motors?

I could totally be wrong. I'm not a SC racer.
