Velineon Brushless Question

[revo_rob_1984]

my question is a little strange but it still concerns me i was driving my Merv yesterday and it sounded like it was hitting some type of Rev Limiter???. . .i was kind of confused on that one it sounded like someone driving a car with a manual transmission and not shifting it out of second gear and having it opened up all the way and bouncing off the limiter, i mean the thing was screaming fast when it was doing it but i was just wondering, is there a rev/rpm limiter on the brushless esc/motor??. . I'm just confused:\

yes thats why gearing to run high speeds is suggested by traxxas

Usually on a brushless system, the motor will accelerate to its highest speed and it will not accelerate any further. There really isn't a rev limiter on the ESC. It may be that you are either hitting the thermal cutoff (overheating the ESC and/or motor) or that you are hitting the LiPo low-voltage cutoff.

i would say first how do have your batterys linked.and what gear is in

my nimh batteries are wired in series and i am using the supplied "high speed gear"

wierd one brother..never heard of that...i run mine all day long with the high speed gear and never had that happen..mine stutters at slow speed sometimes with packs in parallel....check your battery connection...

I know what hes talking about. When I tried running with 4S lipos the car would hit a "rev limiter" so to speak. It was a very fast pulsing of the motor. When that happened, I did some digging around on various forums and found out that stock Velineon ESC has a software rev limiter that kicks in at a little under 60k rpms. It happened to me while running 4S lipo and 23t "high speed" pinion.

I didn't know this, where did you find the info I would like to read up on it. I run 4s but control becomes a problem before it turns that many rpms

I've heard this to but if yiu have it set up right i thought you had it geared low and alot of power makin it snap the revl

call traxxas and b&c i know a guy who does this as long as he has pop they fix him up

Thats exaclty what i am talking about it sounds like i was tagging a "rev limiter". . .thanx for clearing that up for me but i'm not running lipo. . .i'm running 2 NiMh in series

when i run 4s it goes so fast can't hit top speed and thats on small gear.i would call asap
