So, with the revised layout, I attended NEAM at Seaham on Sunday night. Its a all carpet with typical indoor features. On the flat, the car was very good, very sharp, without over rotating. A bit more lively than with the saddles in.
But we had some overlapped gym mats, and small moguls, which the back of the car was skipping about on too much.
I moved the shorty position further back, to stop the back skipping up too much, and this worked well.
I ran like this for the final few runs of the night, very happy with the cars pace ..... rapido.

I can't help but feel, that it'll be quicker with the shorty further forward though, if I can manage to somehow keep the rear in check over the bumps.

Sounds like you liked the layout

Did you try with a new hole drilled in the shock mount ? .. and did you run stock slipper or the stripped down version ?

Hi,
I used a lightweight slipper assembly. I had the shocks drilled around 12mm inboard of the existing inboard hole. See the picture attached.

Could also use the alloy side rails and loose the top deck.

*slight tangent*
Alloy stiffeners or carbon top deck? Which one and why? I'm just about to get the MM carbon chassis and could do with a bit of a point in the right direction! I'll be swapping between carpet/astro and dirt configurations.

Hi Mark, good idea, but this car is a KF1, so there isn't an option of alloy side rails.
Chris.

Cars been going really well in this configuration, definitely won't be going back to the other layout! Been experimenting with 30-50g weight under the lipo in different conditions.

12mm seems a long way to drill the rear shock position! We've drilled ours about 6mm further in and has been working well.

I would definitely recommend this layout, moving the rear shocks 6mm further in on the rear tower, removing the weight from the slipper and 30-50g under the lipo

Try going for larger shock piston holes and up the shock oil wt. to compensate.

Sure laying the shocks over changes the rising rate a bit but mainly it's just making it softer. Easy option is just to use a softer spring. What's the weight distribution with the lipo forward and wonder how this compares with B6?

Hi Dan/ Si,

Can you upload a photo of the rear shock tower pick ups?

I'm currently running my KF2 SE in mid conversion , this is different to your layout I know; however, I also have two extra inner holes on my rear tower. I find this works very well on low grip or blow out grass with 30-40g under a shorty or 80g under a LG lipo . Would be nice to get a comparison

are you running any rear weight with mid on grass? I find the weight too far forwards and wouldn't add anything under the LiPo in mid layout.

Sorry mate don't have a pic but the holes are in line with the existing ones, about 6mm in, and 69mm between centres, Works a treat ...

Ran mine for the first time properly on Sunday at the South West regional at Tiverton, sandy astro with bumpy and cut up grass sections.

I haven't gone well there for a few years now, never have enough steering or traction with the KF2 before ..

Wasn't a problem this time, had kit setup, apart from 1.7 x 3 rear pistons on 400 cst oil. All kit geometry, and diff.

Ran the car with the new forward weight, and stripped down slipper, 50gms under the lipo, staggers up front and yellow mini spike out back.

The car drove a dream !!!! tonnes of steering and enough traction .. even on the sandy bits !! Only change I made all day was to widen the rear track 3mm overall to gain a little turn in off power, and a little more on power traction ..

Gave me my best result for ages ... 2nd in the B final and hunting down 1st place .. just needed one more lap lol ...

Yes mate . 40g under the belt and 10g on the rear of the shock tower.

Hi guys, a question if I may. I ran my KF2 SE for the first time today on a small very bumpy mixed astro track. It seemed to go pretty well, apart from a small steering assembly mishap...
At the moment I only have saddle packs, so I had to run it in the forward motor position. Having read this thread and not having tried anything else yet, how does my layout work compared to the low grip motor position and a shorty? I have the bits to run it forward motor and shorty like you guys apart from the 117 tooth belt, but at the moment I feel a little bit more weight on the rear would settle it down more, thats why I am thinking try low grip first. I have the shocks on the rear and a ball diff, the rear seemed fairly well planted but did break loose occasionally.
Cheers
