Default What option parts?

what option parts should i get for under US$75?
i mean added together.
Im using all stock parts only , with a 27T motor.
I was thinking of getting an upper deck and front one way , but the motor begs to be replaced......

Default Pro-3 Hop-ups

lee82gx;

I forgot if you are racing or not. If your racing, pick up one pair each of the 27mm Pro-linier springs for your car.
Part #'s, 6841, 6843, 6844, 6846, 6847, 6849, 50, 51, 52.

Unless you've been racing for awhile. I wouldn't recommend a Front one-way ($40). Makes the car much harder to drive for most people. The upper deck is OK (I don't use one) but only If your racing on carpet or a "Sticky" prepared racetrack. Also If you can't move the electronics all the way back by using a micro size ESC & Receiver. The batteries are very difficult to change out.

The Heatsink motor plate and Aluminum side bulkhead are good hop-ups that provide more support for the countershaft and cooling for the motor. Otherwise save your money for better batteries, charger, new brushes, etc.
You can use the 6 degree caster blocks to get more steering, that and turn the front hinge pin block upside down (in the instructions)

depends on what pro3 version you have. i would recommend the following:

HB upper deck
pro-linear springs (depending on your track)
heatsink motor mount
graphite arms (use the rear hub carrier that comes with this)
spur gear and pinion to properly gear your 27T motor

Default Front one-way

I ran a Front one-way today for the first time and it really gave the car alot more steering. Only problem was that it sprinkled rain on and off so the track was "Slippery when wet".
After much experimentation, 27t Stock Motors in this car seem to like an overall (final) gear ratio of around 7.00 to 7.20:1. Taller ratios (under 7.00) seems to take away too much punch in the corners. Shorter ratios (above 7.20) top speed suffers.

The caster block is the C-shaped part. They have a number and letter on the inside edge (eg R6), which indicates the side and caster angle of the block.

The hinge pin blocks are the parts that the suspension arm mounts in on the chassis. The standard setting is 2deg, but if you turn the front block upside down, you get 0deg.

The total caster angle is the sum of the hinge-pin setting and caster block.

Here's another:what kind of inserts reduce traction(yes i want less traction)?not considering tires , just inserts.thicker or thinner inserts?

Default Pro-3 decisions

lee82gx;

Don't waste money buying new shocks for the car. Even the plastic shocks work just fine. Put bladders in the shock caps instead of the foam inside the shock, but that's all that is needed.

Use the 6 deg Caster Blocks ("C" shaped) as Sosidge described. I turn the pin block upside down to get less overall caster in the car. This gives the car more on power steering. (from Thad [email protected] HPI) Which it needs because of the flexy chassis.
Some guys run the optional 3 and 4 degree caster blocks. Should be on page 25 of your Pro-3 manual, has springs, gear ratios, and chassis tuning.

Don't use tires/inserts to reduce traction. Change the shock springs to firmer ones.This in itself will reduce traction as your go up in spring rate.
A stiffer insert will make the car more responsive and will reduce rolling resistance some.
I really liked the Front One-way in my Car this past weekend. Only thing it was raning on and off so the track was really slippery.

Default Forgot about turnbuckles

lee82gx;

Replace turn buckles ONLY if you are bending them in mishaps at the track. I bought the whole set of Ti buckles for my car, but have only replaced the 2 that were bent from hacks at the track.
The turnbuckles aren't exactly cheap ($$) either.

Talking Looks pretty nice

I hope HPI decides to keep the shaft design this time

Kind of looks like a mutant hybrid Barracuda/EVOII?

if you have the spec V, then it should already have a lot of hop ups. i suggest you get an HB upperdeck, spring set, spur and pinion gears...that should not cost you more than $75.
