ok...thanks....so you are basically saying we should run truggy gears in the diffs and put a smaller spur and larger pinion to get the same finals gear????

Sort of... it is actually a slightly higher ratio overall than stock that he is describing... just slightly. Going down to a 17 tooth bell would be closer to stock. A big advantage here that isn't mentioned is the extra "meat" in the teeth area of the clutch bell... less breakage! I shread 14 tooth Losi bells like they're made of paper. I went to a 15/48 with a non-Losi bell this past weekend and it's holding up ok now, and the car STILL has more punch than I know what to do with... I think the higher overall ratio he has described how to get would calm the car down. (I'm running stock ring and pinions in the front and rear.)

I followed this up with Traxxas lithium grease on both ends of the spring and it will stay good and consistant for at least a month of racing before you need to clean and reassemble.
The servo saver is the weakest link on the 8ight. They need to fix it to be like the Kyosho or new Xray 808 servo saver. I have emailed them about this to no avail. It is simply not designed correctly for the vertical movement required to make it work right. This is where most of the slop comes from in the Ackermann arm. When the saver flexes it twist the joints and the arm.
Next stop is the gearing and front end.
Worlds are this year!
Come on Losi! Get it in gear!

if they need to change the gearing and the front end soo bad then why are companies useing the same gearing and front ende setups on their new cars.

Oh ok. Found them elsewhere. Why would you think they are longer?
There are instances where the dogbones may come out. I know that we can shim and fix them but I was wondering if they new ones (losa3553 and Losa3554) where longer and you did need to shim.

Iv'e been using the Mugen also. A long time ago in this thread, some suggested the Mugen oils were around 1,000 heavier than the Losi oil. Well, I'd like to test between the two. That and I can't seem to find the viscosity I'd like in Mugen oil. I drive the 8-T also so I'd like to have 9k or 8k Mugen oil. I can't find it though.

I've thought about getting a whole set of the Ofna oil cause they have about any weight you could think of. I realize everything would be different, but that's what practicing is for. LOL.

Default Question about building the Losi clutch

IS there a trick to building this clutch? I am having no luck. I have ruined one composite shoe, and stripped 2 screws. I am going to buy a new flywheel and assorted parts and start over. Anyone offer any help?

Try grinding/sanding a slight bevel on the end of the clutch pins. This will help it get through the rear of the flywheel. But don't put too much angle on and don't take off too much material. Try a slight bevel, work on putting it in, if it doesn't go then put a little more bevel on. Just keep doing this till you find the sweet spot.

Also be sure you're pushing the clutch shoe down against the flywheel so the holes for the pin line up all the way through. The clutch springs will keep the clutch shoe slightly off the flywheel so there is some tension already on the clutch shoes.
