OK so here is a breif write up of how to BTA a CR-01. Its actually relatively easy, and makes these things steer much better with improved Ackerman Angle for almost no $$$$ provided you did not cut the rear arms off the stock knuckels. :frusty:

All you need are a couple of ~3mm spacers, one extra 3.0mm screw, some time and a Excto knife.

1)First you have to remove the lower coil buckets from the front axle and the long tie-rod from the front of the axle. Leave the short drag link running from the servo to the right knuckle in front. (If you are not running the stock coils then you can skip to step #3)


2)Trim the webbing off the bottom of both of the lower spring buckets like so:

3)You can now attach the long tie-rod to the rear arms on the stock steering knuckles (or if you are running some aluminum aftermarket arms if they have both front and rear arms) with the 3mm spacers under the pillow balls and the extra 3mm screw(if you are not running the stock coils and lower coil buckets then you are done).

4)You can now re-attach the lower coil buckets to the two holes behind where they were (moving the coil-bucket back a touch) and use the pillow ball for the push-rod to the shock on the back of the upper screw(see below):

5)You can also move the billow ball for the push rod to the lower hole if you flip the upper screw around so the nut is facing the tire. (I hope that makes sense).

-You may also need to move the upper coil bucket back on the frame rails so the spring does not buckle when it is compressed.

Let me know if any of this needs clarification:thinking:.

Also here are my lightweight (and polished) side plates. They were a PITA to cut and drill out of 3mm-1/8th aluminum plate, but they are about half the weight of the stock frame-rails and plastic side pieces. (These are not almost free, I just wanted to show off a bit :) )
