MarcosJ-will do. It is not available yet as far as I know. It is backordered.
Here is a pic of the new double A-arm front suspension showing the recent changes. The upper shock mount ball is now attached to the upper A-arm hinge pin. This is a Traxas ST (2) kingpin. The picture also shows the slimmed down head of the IRS kingpin.
I have added a third spacer at the rear of this hingepin to increase caster slightly. This will kill a little turn in and add some midcorner steering traction. Because my outer A-arm vertical spacing is longer than stock, these washers have less effect on caster than on the stock suspension. This long spacing will provide more rigid camber support which I think is neccesary on the sweeper.
I have added one washer under the outer A-arm pivot. This raised the roll center slightly. This will reduce the front cornering traction slightly.
Shock Oil Weight
I have upped the shock oil to 35 weight. This will kill a little turn in.
Because I have used the arms and reactive caster blocks on the opposite side of the car than the one intended, the reactive caster blocks work in reverse and add caster late in the corner. This will not be a useful tuning aid.
New Brushless Motor, Ceramic Bearing, Source
I have some parts ordered from Murdock RC
. A new part there is a ceramic brushless bearing set for $10.
This is a significant savings on perhaps a better motor bearing. I have been looking for these. The endbell side will need to be installed with high temperature red locktite and pressed or hammered in with a suitable tool that bears on the outer race. The Novak part has the front bearing already installed in a new endbell.
