My HV Outrunner REVO

[BL-Power]

My Specs:
2x 4s 2500mah 25C Polyquest battery
Turnigy 42-60 500kv Outrunner
Kontronik Jazz 55-10-32

I am using a 18t RC-Monster pinion instead of the input gear. It is a really powerful setup, there isn't missing much for a complete front or backflip. The Jazz handles the Outrunner so nice, cogging isnt existing. I have runtimes up to 35min and the Jazz and the motor are both staying cool.

Here are some pics:

Sounds like an awesome project but the pics no worky.

[MTBikerTim]

Looks good. Now we just need video to see this setup in action. That looks like a huge outrunner too.

Looks nice! I like th red chassis.

Are those 2x 4s packs wired in series for 8s 2500mah or parallell for 4s 5000mah?

[BL-Power]

The packs are wired in series for 8s 2500mah. You can also see the pics here: http://picasaweb.google.de/Brushless...xxasRevoSetup2

The red chassis is really nice, i bought the Revo as a roller from skellyo before Christmas. I'll make a small video soon, but here in Germany it is raining since yesterday evening....

The Kontronik/Tunigy combo is really cheap but working so great that i'm thinking about buying a CRT.5 and convert it also using a Turnigy Outrunner and a Kontronik ESC. I've never had a setup that ran that smooth.

I like the idea, kind of like Sikeston34m's original emaxx trannys. What would you say your top speed is on this, and what is the motor kv? I may have found a use for my knotronik jaxx esc that I have. It is the 40 amp model and will handle up to 25v, so it would be a good 6-7s controller. I may have to try something like this, for my racebomb chassis emaxx.

This setup is not slow, check out the calc:

Differential Ratio: 2.8461538461538462
Transmission Ratio: 1.7222222222222223
Spur Tooth Count: 1
Pinion Tooth Count: 1
Total Voltage: 29.6
Motor KV: 500
Tire Diameter (inches): 5.75
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor coil Ω: 0
Spur/Pinion Ratio: 1 : 1
Total Ratio: 4.90171 : 1
Tire Circumference (inches): 18.06 inches (458.83mm)
Total Motor Speed: 14800 RPM
Vehicle Speed: 51.65 MPH (82.97km/h)
Effective Speed Rate: 1.74mph/V (2.8kmh/V)
Effective KV Value: 500

Definately not a slouch, thats for sure!

[BL-Power]

Yeah, it is really fast and powerful. I can't go full throttle longer than one second because my Crime Fighters are balooning so bad that i can't control my car. Does anyone know some tires that don't balloon that much? The highest speed my GPS recorded was 69km/h. Your Jazz 40 should work really nice with an Outrunner on 6s Lipo.

Could you tell me how you can use a Jazz 55-10-32 controller on a monster truck???
55 Amps is not realy high, and you just use 14.8 volt.

Why all guys here try to buy top notch high amps controller like MGM 16018 if the little Jazz can run the revo.

And another question, can i use this little jazz with a Neu 1515 1Y on 4s li-po??????????

Actually, he's using the batteries in series for 8s, not 4s.

[othello]

The Jazz 55 is quite capable and with 8s lipo (or 10s A123) it is able to push Truggys (see video in my signature) and monster trucks with ease. The Jazz 55 is speced at 65A burst for 15 seconds. It handles by far more when it comes to short impulses. I have quite a few eagletree records with amp spikes around 100A which translates to 2.5KW (on 10s1p A123).

Having 8s and 50A is comparable to 4s and 100A -> around 1400 Watt in both cases (when calculated with 3,5V per cell). With upping the voltage you won't need ESCs with super high Amperage capabilities.

On 4s the jazz 55 won't have the needed Amps for your Neu 1515/1Y (2200kv). On 8s lipo with a Neu 1515/2Y (1100kv) there wouldn't be a problem (this is the setup i will be running in the coming days as my Neu 1515/2Y arrived today).

[mabu]

Yeah - i am using the jazz 55-10-32 in an emaxx on a neu 1515 3d... another guy is using it with a 1512 2y ...

so othello - we can do a run - 1515 3d vs. 1515 2y

[othello]

@BL-Power
>69km/h
No wonder your tires balloon like crazy. I already thought it must be speed demon with an ourunner spinning at 15000rpm without pinion/spur reduction.

@Mabu
Sure thing. It already would have been fun with my Neu 1512 setup.

[BL-Power]

Like othello and skellyo already said, i am using 8s Lipo and the Jazz can take up to 65A peak, i think nearly 2000w should be enough for a 9.7lbs Revo. If you want to use a Jazz on 4s Lipo, you could try a Jazz 80, it can take up to 6s Lipo and 100A.

[sikeston34m]

Very Nice BL-Power!

I've always wondered how the Kontronik ESC's would handle an outrunner in a setup like this. You sound very pleased with it.

Tires that don't Balloon like that? Hmmmmmm...........the HPI Phaltline tires are a GREAT high speed tire, but they don't grip real well off road. They do stick on-road like glue though. The smoothest tire I've ever drove on. I did a few 65mph passes with them. The best I've found for high speed runs so far.

I've heard the Badlands are a pretty good all around tire.
