1.01ci or 16.5cc 8hp measured on a dyno rather than claimed 3.5 with a .21 motor that is actually 2hp, if you are lucky

2 speed to start with a possible 3 or 4 speed gearbox later

THAT is freaking awesome! I only hope one day to become as skilled as this to where I can design/implement my own ride like this. Great job! Please send more pics and hopefully a vid of it running.

I managed to figure out the mechanism for dynamically tuning the pipe. Here is a short video.

http://www.youtube.com/watch?v=-k1ZT...ature=youtu.be

It goes from 275mm to 330mm. 290 is supposed to give me 26000 rpm so a little "extra" just in case..

That's a serious machine ziggy, that pipe system is amazing!!
I am working on a new single speed RS4 where I don't have to use a monster clutchbell and baby spur gears.
I really want to put that HPI .36 in it because of the torque to pull this drive ratio, but I heard mixed reviews about that engine.

You will have trouble with the clutch if you just increase the gearing. Try machining new clutch shoes from brass and use the strongest springs you can find. This might help.

Yea I end up with damaged/melted aluminum shoes alot, I was thinking there has to be something else out there.
But I guess I can break out the dremel and try to make my own out of brass.
You're running brass shoes?
I wonder if these will do better, they have kevlar pads on them, hmm...

Quote:
The Buku Komposite material is almost pure Aramid (Kevlar) fiber and is extremely wear resistant outlasting even the hardest aluminum shoes by 300% OR MORE! In addition the Komposite causes virtually NO WEAR to the clutch bell!
The Komposite material does not burr or deform in any way preventing virtually all clutch failures related to these causes.
The extremely low wear rate and uniform friction characteristics of the Komposite coupled with no wear to the clutch bell create the most consistent and reliably performing R/C clutch in the world!

Now they look interesting! They just need to be a bit heavier for speed runs

If that was to me, it's a super rs4 (little bigger) but I have a few engines to use.
RB WS7III, RB TM928, RB Speedline Xenon-R (holy jesus rpms from hell), Gotech 7-port (nova kangaroo clone), hyper mac 28 (ehh), axial 32rr (ehh)
just picked up a sportwerks .26 engine. (brand new from an ebayuser $86)

They can be had cheap and if modified nicely and a carb change they rev to around 45k.
They are the same engine as the losi mach 427 with a better carb.
Really a beast of an rtr engine, I can say it hangs with the WS7 easily after being modified.

41,000 rpm out of a .21 engine highly modified is the very max. You can get 39,000 put of a street engine if your lucky
