High angle driveshafts

I have a scx10 with a summit 2 speed which I have made my own mounts for, I have been using traxxas maxx shafts and have been having issues with breaking the front driveshaft because of the high driveline angle, i know I could just move the transmission to correct this but if I could use a higher quality or higher driveline angle shaft i would rather do that, does anyone know of a shaft that could handle steep angles like this? I'd prefer to get away from the U-joint style and go to a CV style end but at this point i will try about anything (I'll post pictures soon)
 
Try rotating the front axle forward some.
This will help better align the pinion angle on the D shaft.

The upper link length(s) control that rotation.
Start by adding 1mm - 2mm spacers to the upper links...
while checking suspension articulation
and the clearance of it's movement.

Rotating too far will create other issues...
Including loss of the caster setting.
Some negative castor (king pin angle) needs be.

^ This can be compensated for, by using 8* Chubs and St. knuckles.

If the servo is mounted on the axle...
this could push that forward slightly into the forward cross member.
You could either notch that or some choose to remove it.

I don't like the later idea... so...
I shaved some plastic material off the servo mounts...
this allowed the servo to mount slightly farther rearward.
Was enough to clear the cross member.

I'll try clocking the axle, I just don't want to lose my steering angles, and I won't have a problem with the servo because it is mounted to the frame

Use adjustable c's ,that helps alot.
^ I'll agree...

I use the Axial 8* C hub/steering knuckles.

After rotating the axle forward 2mm (upper link ext. length)...
the 8* chubs/knuckles will compensate for that axle rotation...
by increasing the caster angle.

Unfortunately... these are only available in alloy...
and they're not very cheap to purchase.

VP sells High Steer knuckles... (more costly then the Axial alloy stuff)
but keep in mind...
The knuckles steering arm can interfere with fitting wider 2.2 tires...
or possibly even wider 1.9 tires.
So know that going in.

I have a few friends that have purchased the VP HS knuckles...
and wished they hadn't.
Because they are now limited in what tire widths they can roll.
