Help I Keep Breaking Front Arms

With the K2 Schumacher sarted using an adjustable hub design that required
a relief cut in the arms for the steering knuckle to clear. The easiest solution
until a revised arm is to run the old style arms without the relief cut. Run the
hubs in the High position and set your steering end points down so the steering knuckles don't hit.

SCHU3597
SCHU3407 MED Flex

There is a newer batch of the SCHU3407 wishbones which correct the weakness in the previous front arms.

Suggested upgrades/spares
Strongly suggest to buy 10 alloy front alloy pivot blocks-U3556 the A & B front plastic pivot blocks-U4798 will break soon.

Have some shock seats spares, alloy v1-U3611, plastic-U3937, alloy v2 (off-road)-U4890

Have some spare shock shafts available U3668 & U3669
MIP pucks an Excellent option!

Misc

Other wheels that fit apart from the Schumacher wheels
Losi 22-4 wheels will fit on the front the rears will work as well!
AE b4, b5 & b6 will fit on the rear
Be sure to lock tight the track screws and rear strap this is a must!!!

AE (12mm) and KYO fronts will work with .5mm spacer - available through AVID


Don't buy the purple titanium turnbuckles as an upgrade there thread is too small and they wander too much. Lunsford Super-duty titanium turnbuckles fit very well they are 3.5mm threads. Get the 1 3/4", 2 1/8" & 57mm lengths. I did not replace the Centre Track Rod.

** When running the Super Duty turnbuckles with the stock captured ball ends, be sure to check for binding in the front steering and camber links after each run - tumbles and glances off the pipes cause them to flex and slightly twist and can bind up the front suspension ... The fix? - simply take a turnbuckle wrench and twist the link back and then forward to it's original positon .. consider doing this as a maintenance step after each run ..

Suggested Gearing

5.5 - indoor high bite clay 83/20 (+/- 1 tooth for layout and conditions etc)
6.5
7.5
8.5
9.5
10.5
13.5 At SRS Arizona I ran 75/28 buggy was quick! RCM lockout worked great!
17.5 - FDR between 5-6 depending on track. E.g. 35/66 down to 30/69 slipper eliminator in use. Different options within the thread. I use B5M exotek eliminator and file it to fit.

I recently took 1st for our local club winter series race in the 13.5T Super Stock class with a combination of Michal Orlowski and Larry Myers setups, plus some lightened parts with lighter 2WD front wheels, slipper eliminator, plastic parma pinion and MIP shafts, more info here:
REVIEW: Schumacher CAT K2 - Stadium Trucks & 1/10th Buggies @ URC Forums

see full list of recommended upgrades for 13.5T racing in the OP of the thread.

Why? Facebook is such a horrible way to discuss anything.

I've stopped following a bunch of alleged "friends" due to forcing their political beliefs on me... but in general, I find that folks tend to be more courteous when their picture/name are exposed... I see too many trolls on the forums who mask themselves behind an avatar and somehow feel they are above everyone else... I think the day is coming where we will see a shift in social networking on many different levels as various marketing levels mature.

As long as they don't rub the bearing you should be fine. It really is gonna
on who made the wheel, I have had some that rub and some don't. Be prepared
with some wheel spacers just in case. They have a slightly narrower offset than
the Schumacher wheels, about 1mm per side.

Anytime you use any other wheels there is a chance the hex will be to deep and they will
rub. Keep some of these around.https://www.amainhobbies.com/schumac...hu4321/p260374

Pretty much every company that makes a T/C has these so there pretty easy to find.
