A question for you guys that have made either the XR or the Wraith mod, how is link geo effected buy the shorter front links?

Running the stock wraith linkmounts move the link far away from the center of the axel.

BliB · 02-25-2014, 04:27 PM

Well look at this!

With axial 80128 short plastic hubs this axel meassures 200mm that should be 7" 29/32!

Sorry for the mess on the workbench!

Hey BliB, looking sweet with the wheels and screws, color scheme!

When I did the xr mod, I used xr housing, which widened an shortened the fronts but also used Bwd rear shock an link mounts. It kept my wheel base at 8.5" and haven't noticed any link geo issues. Everything works beautifully!

BliB · 02-25-2014, 05:07 PM

Thanks! Pretty darn satisfied myself!

The wraith mod really move linkmounts and shockmounts away from from the axel, stock is maybe 10mm from center of axel to center of the link screw
And i guess about the same for shock screw!
But the wraith linkmounts is about 20mm and the shock 22mm!

The XR mod give you 15mm i guess?

I'm going to try a home made mount, got a couple ideas on how it could be done!

Today the bananahangers from rc bros arrived! Really hope i can make them work with the 1.9 wheels from DLux

BliB · 03-07-2014, 11:58 AM

Okey! The bananahangers had some minor problems but all of the are gone!

Had to make the hole to slots to move the holder closer to the knuckle!

The plastic hub is much bigger than slw hubs so they had to be modified to! Both to clear the wheight holder and the wheights.

Last thing I did was some grinding to the axleshaft.

Nice work.

It's funny how nothing ever fits, but ultimately works when you're not afraid to cut.

BliB · 03-07-2014, 03:35 PM

Yeah, talked to william(?) at RCBros, told him about the issues i had and he told me that he gonna change the design

That is a great vendor!

A video of the shaft i played with earlier ;)

Oh god, this is a family forum man, we don't wanna see you play with your shaft

winnerone23 · 03-08-2014, 06:53 PM

I think he needs to play with the shaft some more.. till he can get some real turning radius out of it!

BliB · 03-08-2014, 11:37 PM

Yeah i need to grind that joint a little more!
Would be fun to see how much loss in torque at that angle!
My bet is someware around 90%!

Need some testing but it feels kind of alright!

BliB · 03-22-2014, 03:08 AM

I've been inspecting this little 12t gear.
And even though I've done some eyeball n dremel engineering to the teeth it feels like it got pretty much the same play all over!

This thing started out as an axial 30771.

The shaft is turned down to 4mm all over and removed the little shaft outside the gear.
Then the final task for the lathe is to make the angle, about 18 degreese!

Last thing was to shap new teeth with a dremel and a cutting disc!

Think this can be something!

lowridinjuggalo · 03-22-2014, 03:43 AM

It looks real good

BliB · 03-22-2014, 04:02 AM

Thanks! But i know that alot of you guys got way better eagle eyeball engineering skills!
That would help alot! I got shakey hands and no patience!

BliB · 04-11-2014, 08:58 AM

This build have been standing still cause I've been working alot and away from home, but when i got home yesturday a little package from Dravpnir was waiting for me! Pics will come later!

BliB · 04-12-2014, 12:50 PM

Purple lockouts, ti links, delrin chassie, SS spools with exeed gears, front servo mount with electronics plate, a rear upper linkmount and a LRP Fusion 370 motor!

Now it's hard for me to decide what engine to choose! I got the losi insane, xtreme heli engine, and now LRP fusion 370 if anyone can tell me where to start i would apreciate it!

Still thinking 3s and i got 70t spur!
15t front diff pinion 12t rear diff pinion

Dravpnir · 04-12-2014, 02:32 PM

Enjoy the parts mate

BliB · 04-13-2014, 01:12 AM

I'm pretty sure that i will!
Feels great to throw that stock locker ring gear assembly in the bin and replace it with your locker!
