Neither did I. Haha I heard someone at the track talking about putting foam under the tank but I had never heard of it. Just making sure.

How are you guys shimming the front and rear diffs?

Eddy,

I put the foam from an old air cleaner under my tank just to help cushion the tank in the event of a really hard landing.

I've got 2 shims in both my front and rear diff. I've also got shims in my centre diff to take out the play there aswell. If you need more than 2 shims I'd look at replacing the bulkhead.

Just like any car, you want as little play as you can get. Both side to side in the housing and between the ring and pinion

What kind if surface do you run that spring setup on (bite, smooth or rough)? I have been preferring lt blue front orange rear lately but will try all lt blue to stay consistent with your recommendation.
My Son ran the outer hole setup at the recent National Titles here and the track was grippy but the setup will work on Moderate grip tracks also and seems to be stable through the rough.

Of course there will be times where a tweak to the setup may be needed on loose tracks such as orange springs on the rear.

I just switched back to the stock pistons. 32.5f / 27.5r with TLR oil is working great in my car with the rest of my set up. Its a good starting point in 60-65 degree weather.

My diffs didn't have much side to side play within the housing, so I didn't use many if any shims for that, but there was just a little slop between the gear. I did notice that the pinioin gears didn't make full contact against the diff gear. I shimmed the pinion gear by sliding shims (from KYO96643) on the pinion shaft before putting the shaft through the bearings. The shims fit perfect over the shaft and only touch the inner race of the bearing, not the seals. Since the pinion's gear have a wider diameter the more it gets shimmed toward the diff gear, the tighter it gets, which takes out the little bit of slack that was there. A little unconventional, but now the teeth are making full contact and haven't had any problems since I did it numerous months ago. The diff spins true and smooth.

I run a piece of thin sponge under my tank. 0 issues since the original TKI1. Plus it helps soak up overflowed fuel during pit-stops for "less mess" on the chassis! Only issues I've ever seen with Kyosho tanks are on the ST-RR truggy.

Yeah, I noticed that there wasn't any side to side play in the bulkhead in order to shim The diff. I couldn't even get the diff in the bulkhead with one shim. But I will definitely go back and shim the pinion.

Thanks a lot for that will hopefully have a play with that this wknd.
Getting myself a set of orange springs may also be a good idea for my home track as its very loose...
I hope to be over ur way next fortnight for the night meet. I will run the Cody king setup as a start, it will be the first time I've ran my mp9 on that track. A bit excited

Good to know. I just rebuilt with Mugen 450F\400R that comes out to about 35 and 30 Losi so Im not far off. I have the light blue springs on now but plan to give the orange on the rear a try tomorrow.

Just building up the Mp9 TKI3 now. The rod ends are a complete and utter ball ache to do. Any easy tips, as my fingers are killing me trying to do this manually!

+1 was difficult to put shims in side when building from new, after break in though its possible after a few meetings to get a shim in, as for the pinion shaft I also use a clutch shim .010 then push the centre Universal on tight no gap and as you say spins nice and free but with no movement

pliers

the side of the ball end that has the shiny ring from the mold just visible around the orifice that you would insert the ball is the side you would wanna install the ball from , after you assemble the ball/end squeeze with medium heavy pressure on the sides of the rod end with the pliers , this will stretch the rod end a lil and provide for free suspension movement
