I liked the stock springing better with the KingHeadz shoes (7075) 2 gold, 2 silver. Tried 2 gold, 2 green and didn't like it. I'm going back to the stock springing...

just a question are you 2 ali & 2 plastic or 4 ali shoes?
I run 4 Ali (kingheads 7075) with either 4 silver or 4 gold springs depending on the track suface and layout etc I'm running this setup on both my plus5t & my modified GO tech 7port turbo and it hooks up really well and the wear on both the shoes and clutch bell is almost non exsistant after 7-8 litres of run time I don't bother running the plastic shoes anymore as they don't seem to last more than an hour of run time before they're shot

I was looking at the Go Tech motors yesterday. What is it with the short plugs they run.

They are OS plugs. OS and Go Tech are the only two manufacturers I know of that use them. You can use a "standard" length plug if you double up the copper washers on the plug.

I too have ran the Losi clutch quite a bit. I use the KH 7075 shoes and they do wear very well. It seems the silver and gold springs make it work the best. I have tried all combinations with this clutch and even used the plastic shoes as well.
Has Losi made a change in the plastic material? It seems as the most recent material is different from the first stuff they released. The new stuff runs well if you spring it right and don't let it slip as much. I found if you run the Alum shoes at the same spring rate as the plastics you can tune the clutch's hit hardness. The addition of a single plastic shoe will just take a little off of a 4 shoe Alum setup.
I ran all 4 gold springs with a RG that comes to its power band kind of slow. I ran 3 Alum and one composite shoe and it was awesome. The plastic bleeds over onto the Alum a little to soften the grab just a little. You could now drive this motor at 20% or 100% and it would clear anything.
When i went to a more aggressive motor like a MoJoe Nova P5 i just went to all silver springs with 3 alum and one plastic. Smoking take off but very drivable in the low RPM range.

The shoes do last a good long time this way. If you spring the plastics softer and let them hit first then they go away quick. On two hard springs and two soft springs it worked better if you ran one plastic shoe on the soft spring and one Alum shoe on the same spring on the other side. You take away the hard hit of the Alum but maintain the wear and smoothness you need to drive the delicate stuff.

I have grown quite fond of this clutch.

I did'nt think you could run only one plastic shoe. I thought it would wear on the bell or the shoes too much. Thanks Tex

I thought you shouldn't do it because it would put a nasty imbalance on the end of the engine and possibly start ruining engine bearings or vibrating stuff loose on the chassis.

Maybe it's not a big deal though. It's not like these things don't already vibrate.

This is how finger clutches work in all the cars with two speeds. Never had a problem there...

Adding plastic to alum shoes just make the hit a little softer. It is almost like combining materials. As long as they hit relativly at the same time there is no increased wear. The plastic will wear faster than the aluminum but not out of the realm of wether you would consider it or not.

They need to be setup to hit opposite of each other using the same spring. If you are real skeptical then you might equalize the weight of the shoes to make sure they will hit at exactly the same time when using the same spring. Kepp in mind the lighter shoe will enguage after the heavier shoe.

On that note, all of the aftermarket shoes are different weights than the stock stuff.

Surface area, weight, spring tension, material adhesion and how quick your engine hits its powerband are all things to consider wehn tuning a clutch for given track conditions.

Now we just need some Rulon shoes for this baby! Hear that Losi?????
On road guys run this stuff for a reason!

I wouldn't worry too much about an otu of balance clutch (3 plastic and 1 alum or vise versa) because before the 8ight came out everyone ran 3 shoe clutches and most everybody used like 2 plastic and one alum shoe or 2 alum and one plastic shoe.
