Copperhead and braking?

I just put the 4500 copperhead in my SCTE ( new to me bought used roller ) never driven a SCTE.

Just going up and down the street in profile 3 or 4..the brakes seem horrible. can i make it brake better or does the losi just weigh a lot more than my slash 4x4?

Other than that..the thing rips...just not used to hitting the brakes full on and having it "slow down" I'm used to locking the brakes and almost doing nose wheelies on my slash.

THanks for any help. I have the viper pro guague if that can help.

Check the instructions - if you didn't buy one yet, you can download them from the website.

Mundy - you got the right idea!!

nitro - good question - I haven't run any motor other than the Viper. But there are a lot of factors that could work into that situation.

Make sure brake strength is at 100% in radio. Set Brake to 10 on progauge, and use exp+3. This is what I run and brakes are plenty.

I have been running my new 10r/ 17.5 for a week or so now. I was wondering what some of you guy would recommend for gearing? I'm driving a B4.1 worlds with reedy 60c packs. Thanks!

I think my copperhead just died in its first time out.

When i put the truck on the ground it just makes a whining noise and doesnt go. if I pick the truck up the wheels will turn fine. It was working fine for awhile but would have a weird lag. where it wouldn't go full throttle then all of a sudden it would kick in.

Motor has 5 minutes on it.. never got over 100deg. 15T pinion. was just screwing around in a parking lot.

If I push the truck forward by hand it makes a squeek/wine in the motor if i push it in reverse it makes the standard click click click of the motor turning over.

Any ideas? I'll post a video soon. Losi Ten SCTE butter smooth if i pull the mesh apart so the pinion doesnt touch.

Ok here is the video, whats wrong with this thing?

Since your doing video I would suggest taking close up of what the pinion is doing during this.

Your video jumps around so much its only really worth the audio.

Show the motor and pinion close up with it sitting and making the cog noise and also while it is raised and the wheels are spinning.


This may help someone identify whats going on.:nod:

The pinion does not move when it makes that noise it just sits there.

Basically the motor just slips.

are u running blink or boost? ik guys running around 33 69 doing well, these motors can prob take a 35 if possible, they run cooler than most!

are you sure you have A B and C connected right?

It sounds to me like you may have B and C switched.

IS the pinion tightened down on the shaft correctly? I know it sounds dump but this seems to be what it sounds like.

Yes its tightened down.

A, B, C? doesn't matter on this the manual says you can plug them in anyway and if its backwards just switch two wires. None of the wires or ESC plugs are labeled anyway.

Pretty sure the motor is toast :( as it was mostly working for a couple minutes then just started slipping.

Edit: Just took the motor off the truck and tried spinning the shaft with my fingers, it doesnt "cog" at all anymore I can turn it it just squeeks, no click/cog like its supposed to.

33/72 or 34/72
my B4.1 with 17.5T flys with it

Sounds like a motor that went bad....do u have another motor to try w the esc?

I have ran from 29/69 to 35/69 with no problem and it does work great. I was just seeing what other might be running. I seem to be lacking some top end. Oh and I am running blinky with motor timing all the way up. I have raised the PWM (I think that is what it is called) up to 8000 or what ever around there. Sorry I forgot the exact freq, and it's linear. It is a super smooth motor and speedo and holds lots of torque even geared so tall.



Thanks, I might give that a try or at least somewhere near there.
