Default Alex shocks

The Alex shock can easily be made to fit the smaller diameter AE and Tamiya springs. Just flip the upper shock collar upside down and use a tamiya lower spring perch. I remember trying an AE spring perch, but it interfered with the arm.

Square also makes a Tamiya spring retainer, so it should fit also:

For high bite carpet, the alex springs just aren't stiff enough.

Default REEDY RACE PREP: Dialed SPOOL setup.

For those planning on attending the Reedy Race, I've been working on a killer spool setup. This car recently dominated the 19 turn class (3 qualifying heats) at Speedworld. I got the car to carry silly corner speed with a spool with no hint of corner entry push.

Front
1.5 x 6.25 spring (17.09 lb/in), outer hole on arm and outer hole on shock tower.
30 wt oil with HPI #2 piston.
No swaybar
SPEEDTECH Prototype Spool
mid-span arms

Rear:
1.4 x 5.5 (15.69 lb/in) spring, outer hole on arm, 4th hole (counting from the outside) on the shock tower.
1.0 mm swaybar.
30 weight oil.
rear arm mounts raised 2 mm.
mid span arms.


The light front oil really lets the car dive in hard with a spool and the raised rear blocks lets the car rotate better during "rolling off throttle" corners. On-power steering was just plain silly with a spool. I can't figure out why, but the car carried a little more cornerspeed with the front swaybar off??

linger with the front sway bar off that will make the car roll more in to the corner while the rear stay flater..linger if you remove the rear sway bar ,I believe it will make the car push ..Does your car drive twitches or react fast in to the corner with the front sway off?

Hi OVA,
I almost always use a front swaybar with a 1-way. The car spends less time rolling and more time twitching. However, with a spool, the front swaybar was contributing to a off-power push.

Yes. Here is a picture. You will need two sets to do all four shocks. Also think about getting shock bladders for the caps.

I'm thinking it'd be a good idea to replace the washers on the R3 steering rack with nylon ones or a good plastic anyone got any idea's on where i might be able to get these washers ??

The idea behind it is that they won't grab the alloy speedtech rack that i use.I've greased up the standard set-up now and it's better but i think changing the washers is the answer to a perfectly smooth steering rack.

I should also say the "grabbing" is probably due to me removing some material from the nylon spacers and alloy rack mounts to reduce all the free play in the steering system as standard, mine is now almost play free!
