Time to waken this project up a bit I think...

Got some wheels for it! Some enlarged 1.9" red Rovers with gold Voodoo sidewalls from Everetty.




Some weight comparisons:

Reduced and narrowed silver Voodoo




Enlarged red 1.9" Rovers with 2.2" white Rovers sidewalls




Enlarged red 1.9" Rovers with gold Voodoo sidewalls. The weight will decrease a little bit after I shave them and make some breathing holes.

That kid does some super tire work.

Got some spare time so things are on the move with this project. Got some parts today, but I am waiting on a box of wonderful things from across the pond

[Dravpnir]

Hmm... Magic Axle






As comparison, my home made titanium version of this axle weights 20 g and the original out of steel, 40 g.



I do not know if this idea will work, but I got to much good experience glueing CF to aluminum, and it its to light and stunning not to give it a try

The aluminum is a cheap soft grade, so if that do not last I will try 7075 or titanium instead.

The ends will be threaded to M5 when I get back to work on monday. I also have to make a fixture to keep the axle straight when the glue cures.

Wow!

I'm not sure that I would trust having glued joints in a rear axle, but that is beautiful

I have some trust issues myself regarding the glue joints... and the aluminum... and the CF tube, but just gotta try it

But if it seems to work, I will go on and make a version for my "comp Berg" too, but with a built in locker for the 4th V1 gear. If the axle can withstand my cobalt magnet powered confluxes I got on that Berg, it should work for most applications.

Progress is the art of compromise. You are on the thin line between performance gain and risk of failure. Lovely parts man for sure.

Thanks for the wise words


Waiting for some nifty stuff to arrive to really start the restart of this project. In the mean while I have started to CAD some more parts. This was tonights work

Outstanding work, Ride that line!


What turn are your 400s? We found the 16t to be best combo of torque and speed, the faster ones saturate the brush and torque suffers. We still have plenty of arms and brushes and blanks if you need.

My 400s are 13T. I have a 14T somewhere I think but not sure.
What would a pair of 16T arms cost? I plan to run this one with a 2S lipo, is the 16T still the best option?

[Dravpnir]

There, axle parts all drawn up and printing ordered

Really good job! Very nice...

The all white looks awesome. Are those internal wheel rings something you will be selling?

Thanks, and if the internal wheel rings will be sold it will be dlux that sells them.

Lots of tasty goodness going on here.
