I finally got the Viper Buggy motor in. Packaging is excellent and delivery service is top notch. I will post more once I get some free time.

It's rated at 1800kV
2 Pole rotor with 3 slot stator
5mm Pinion shaft
7.35mm Rotor shaft cut down to 5mm in the front
4.47mm Rotor shaft in the rear. So rear bearing is smaller than the front.
45.04mm Magnet length
13.82mm Magnet diameter

The motor feels notchy.
The back cover is plastic.
The sensor is replaceable.
The rear has a rubber seal.
Assembly is very good.
Front motor screws are 2mm and the rear are 1.5mm hex.
Heavy copper tabs.
Front has shims and spring assembly.

Hahahahaha!!!! Man, I thought it would be at least 24 hours before we saw disassembly pictures. You and Andreas crack me up, you have to take everything apart as soon as you get it. Hahahaha.

hehhehe. What's the point of bringing a hot girl home and just stare at her. I undress her pronto:lol:



So this motor is what the LRP tried to be. 2 Pole spool up quicker than 4 pole motors. A 2 pole can take more timing and this motor is basically a 10th scale motor supersized to McDonald porportions with large fries. So you can use turbo as well.

I can't believe Dean didn't let you undress his motor.



I'll run the motor on 4s in my GTP and see how it does. But first I need me some more bullet connectors.

Did a test run today. It's nite and still 100F outside. The motor is what I expected to be. It has a bit more power then the LRP 1/8 motor. I couldn't get it started in sensored mode with the RX8, so I just ran it in sensorless mode. The RX8 started up the motor just fine. I'll check later if it was my sensor cable or maybe just a bad sensor.



I just ran the GTP up and down the street. The power was nice and smooth and braking was strong with my gearing. I did some hard starts and hard braking just to see how the motor would do. The motor was @ 176F and the ESC was @ 107F.



My conclusion so far; This motor is good for a light 1/8 scale car or when the weather is cold. Power band is smooth making for easy driving. I still need to figure out the sensor issue.

Interesting analogy. Now I'm afraid to know what you do with your motors when you're not taking pictures. Hahahaha.

hahhahaha.


I did forget to mention that soldering on those heavy copper bars is badass. Makes for one solid connection.

Heat is the killer here. The motor would be a lot better with a bigger diameter rotor. The 2 pole C50 Hacker motor is still the better 2 pole for buggy use, but cost twice as much Sad . The LRP was a better design but still too small for buggy use Sad . I'll try a 18T pinion and see how the Viper motor does heat wise. Keeping the peak current lower is key it seems, as continuous power is low. I will also have to mess around with the timing.

Yesterday I ran the motor again and result is FAIL!

Runs too effin' hot man. 170F running half a pack is not exceptable. menMolestor comes to mind. I had to ease on the brakes and throttle to get to 150F. Was like granny drivin' in loserville county. I had more fun driving a 1512 1400kv 4pole motor. Sensor board on the motor is toast as well. My son's 2 pole C50L 1800kv Hacker has more power/excelleration and runs way cooler.

Did a few test runs again with 0 degrees timing. Temps where much better.

Run #1 measured with Eagletree V4 150A.
Tekin RX8
0 timing
Stock brakes
4s hardcase Acepow
20T pinion
Ofna GTP 47 spur
Peak Amps 157.35A
Peak Watts 2069W
Continuous Amps 22.08A
Continuous Watts 324W@14.68V
129F


Run #2 measured with Eagletree V4 150A.
Tekin RX8
0 timing
Stronger brakes
4s hardcase Acepow
23T pinion
Ofna GTP 47 spur
Peak Amps 162.21A
Peak Watts 2039W
Continuous Amps 27.67A
Continuous Watts 400W@14.44V
142F

So it looks like I can go up another tooth with the pinion and still be good with temps.

True that.



Useless for 1/8 scale. To think they were bragging how well the motor was doing in beta testing. Laughing Laughing Laughing Laughing The motor would have been so a good for onroad if it was slotless. There would of been a whole lot of copper in there as well.

I assure you the timing is advanced to at least +40 degrees and the turbo is programmed to only engage after lunch. Hahahahaha

Lol. After I eat about four Lenny's Subs. I'll be putting out too much gas a BrownBioSubstance submarine might shoot out. And then I might need a new horsebehind Ring Job.
