Are the 4 pole 550s going to be the same length? Dont really want to cut my my chassis. thanks

No, they will be more inline with a 550 size motor.

The 5mm shaft R series 4 poles are going to be longer than the 3mm shaft versions. We are using the same length as the L 550's, which is shorter than the VST XL's and will not require any trimming to get the motor into the SC10 4wd.

That sounds good. I already have a pro4 on the way but I will probably just sell that and wait for a 550 4 pole then. Outdoor season is ending soon where I am anyways so I guess I can wait a little longer for those.

What do I want to gear this thing at? I have a 12 tooth on it right now.. but someone was telling me hat these are torquey motors... so have to compinsate with a 14/15ish?

I managed to finagle, grind, whittle, and sand my way in there!

It's a good system, I have been running it the last month without issues in my SCTe. I can't wait to get my hands on the R52, it's going to be a monster in the horse power department.

Nice, that is a very clean job!!! Thanks for the pictures also!

I run a 14T on the 5.5 and it gets up and moves nicely and very smooth. Don't run any boost/timing on the 550's. They come stock from the factory with 30 degrees on the can. If you need more speed gear up.

A friend/regional viper driver gave me these settings to start with...

Brake strength - 80%
Brake PWM freq - 8000HZ
Brake curve - linear
Neutral drag brake - 10%
Throttle PWM freq - 9600Hz
Throttle punch - 75% - 90% depending on traction
Throttle curve - -1Expo
Deadband - middle
Stock Blinky mode
Motor temp cuttoff - Disabled
ESC protection - 200 degrees
Holeshot mode - off

Anyone think of anything else?

How are these 4 pole motors compared to the VSE motor, My question is would in work in 1/8 th scale with a 10r

Yesterday was my first day with my Viper R/C VTX10 ESC & VST 7.5 motor. I love it. I got 2nd in mod 2wd.

This is what we at Viper recommend.

VTX10R-Profile#2
Brake strength 80%
Brake PWM freq 8000HZ
Brake curve linear
Neutral drag brake 10%
Throttle PWM freq 9600Hz
Throttle punch 15%-20%
Throttle curve linear
Deadband middle
no timing- default
no motor protection
esc protection 240 degrees

No, it's a 1/10th scale system, it's benchmarked in the SCTe so unless you are rolling a 810, I'm going to say no.

Saw the results!! You had a very short time for setup last night and did very well. Nice work!

My Viper powered Kyosho sc ran great last night. TQ'ED and won open sc A main.

+ YouTube Video

Doesnt look like very high competition ther for ya..

Looks good!

Can you PM me all your ESC settings by chance? Im new to Viper stuff, going to get a system from my SC10

what motor was this 4.5 or 5.5

Either, 4.5 or 5.5... Just gearing would be different.

Isnt 240 on the esc kinda... high?!?
