Thanks again!
My list of must have parts (although some may disagree)

1) HPI Springs (1x Pink, 2x Silver, 1x Blue)
2) Steel front 46mm driveshafts
3) Split 1C blocks for the front
4) Gear Diff

That little list pretty much makes the car bullet proof, and handle the best outdoors...

HiH
Ed

Ed, where on the web I can get those set of springs?
I already have all the rest you stated.

Hey Ed the 46mm driveshafts what's the benefits? And for the split blocks can you reverse and use a 3mm shim like what Jillies does with the single block.

thanks David

46mm driveshafts, I find they look after the spool cups better, as the dogbone sits deeper in the cup. And being steel they don't bend... it's one of the first things I switch out on the car.

Regarding the 1C split, they don't require any shims underneath to be in the same position, but it does mean you can't lower the roll centre any more (like Jilles did at TITC). Personally, I didn't like the car with the low roll, so haven't tried it since..

Interesting..Ive always run the 46mm in all my cars but found it ate the inside of the spool cup to the point where it bound up the arm. I did find that I broke less cups though. Have switched back to 44mm shafts and feel the car is nicer to drive.

HiH
Ed
Awesome guys thank you for this insight. I think i have most of this already except the springs and gear diff. I'm going to build the car w/ the ball diffs and then install the gear diff in the front of the car.

To be honest, it is something I've been meaning to go back and try (44mm vs 46mm) as haven't done it with the 7 yet... but as long as they are steel is the main point, IMO
Blue alloy = look nice but bend easy!

Here is what I've found/noticed between the steel 44mm and 46mm shafts. From a drive cup durability stand point the 44mm has a tendancy to break off the end pieces while the 46mm has a tendancy to dig grooves causing some binding. I didn't notice any difference in steering between the stock shafts.

I used 300K CST (Xray) in my front gear diff and was very surprised at the amount of diff action. The laps time confirmed that the spool was faster. I haven't tried 500K yet but that should get you closer to the spool in terms of pull out of the corner and yet offer up the increased steering that you would expect from a diff.

I agree with this. If you compress the front suspension the 46 shaft will bind in the cup. But the 44 notches the outdrive quickly. Let's face it, the original cups are awful.

I tried the Tune up and Roche cups they are a vast improvement over the original. Roche cups are quite short and fit the 46 only but clear perfectly with suspension movement. Tune up cups are long like the originals and fit the 44. Naturally they bind with the 46 under compression.

I think the 44 definitely drives nicer than the 46, and the Tune up cups are made from very long lasting material. I bent the mounting pins slightly to remove the slack. 3 months in, racing 2 or 3 times per week there is minimal slack, my car drives super consistent, and no retirements due to failure. I'm extremely pleased with this product and would regard it as an essential upgrade. One less thing to worry about.

Got mine here. Use Tamiya AW grease.
