My HV Outrunner REVO - RC-Monster Forums

BL-Power · 02:12 AM

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.

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?

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!

Oh, I like that setup alot. Tell me, how difficult was it to get the motor hooked up in the correctplace? Looks like the shaft slid through the front bearing, then you marked the motor mount fastening positions on the existing plate, and fixed it in place Im guessing the input gear for 2nd is retained and just fixed to the motor shaft in the correct place; any chance of a sneak-peak inside the tranny if its not too much hassle?...

Thats exactly how i did it. It wasn't difficult at all, it took around 10min to drill the holes.

I am using a 18t Mod. 1 RC-Monster Pinion instead of the input gear for 2nd. It is working great.

Thanks for your recommendations! I'll look for some Phaltline Tires for onroad runs.

I'm glad you like it, i'll see if i can make a video today.

Howdy, could you elaborate a bit on how your actually driving the top shaft? is that like a custom shaft you have the motor, or did was original shaft on the motor long enough so you could just bolt it to the tranny?

Also, is that shaft supported on the other side of the transmission like a topshaft normally would be?

BL-Power · 02.01.2008, 08:48 AM

It's the original shaft of the motor, it's long enough to mount the pinion properly but it doesn't reach the bearing on the other side of the transmission.

You can also convert the 18t input gear from the emaxx tranny to take a set screw and use it as a regular pinion. Some heat treating is necessay if you want to run on a hardened spur, though. I really like this idea, and may try it out in my racebomb. It has 1/8 diffs and sturdy driveshafts so it should hold up!

suicideneil · 02.01.2008, 12:11 PM

Cool. Being a 5mm shaft should mean it will work fine without being supported at the tip, although I know Sike can make custom motor shafts that woud be long enough if it was ever an issue. With that motor mount though I doubt it will flex at all, very solid setup.

sikeston34m · 02.01.2008, 12:33 PM

I love this idea. I think BL-Power had a stroke of Genius when he did this single speed tranny conversion.

It doesn't have to reach the bearing on the far end. The motor shaft is some very hard stuff. Great IDEA!

Thanks, i'm glad you like it also.

It's really durable, i was at the skatepark today and after 30min of running und some huge jumps and everything ran as smooth as before.
