K2
 

It looks awesome in the flesh, really nice design features. Will work well.

Dear santa..... As ive been a good lad, this year could i have........

The bodyshell looks a bit odd; as though someone took a KF2 shell but forgot it was going to be put on a 4WD, so they lumped some extra lexan on the edges. It kind of reminds me of the SX/SX2 shell.

It does look nice though, and it appears to have a very low CG. In practice it pulled out of the corners like no other car, it stays very flat under load, almost like a TC. Looked to have a little bit of understeer, as he was the only car (that I noticed at least) that wasn't able to sharply rotate around the apex at the end of the main straight. Could've just been a product of being quite stiffly sprung, it seemed to have a lot of rebound over the little doubles and small jumps too.

I'll watch orlowski tomorrow, only watched Dave Poulters so far. I doubt anyone has under steer at this track. I've removed six rows of pins and glued sidewalls in 4wd.
Car looks long and thin. Reminds me of Darc Durango.

Michał said they were trying to get some more steering from it, but it ended up with less, which explains the lack of rotation.

I didn't see it grip roll a lot though, and he only had 3 rows off on the front and one off on the rear. 8th on the first day is a very strong start.

Both roll bars look so thick on michals car though. Plus stiffish springs on front. That has to be contrabuting to the understeer. But as ever with setup its balance.

guess i could use the sx3 body on it

Any news on when it will be released?

Probably after the world's before Xmas

carry over parts from K1?
 

Hello all,

I have been running schuey 4WD buggy's since the release of the SX3.
So I have a nice supply of spares for my current K1 (soon to be retired).
Do we know which parts will carry over from the K1?
I am hoping arms, hubs, diffs, steering blocks, etc.

Regards,

Hans

Any word on a release date for the K2?

Word on the grapevine is the middle of Nov

some shops stating available mid november to pre order.

Looks really good Schumacher released another top car.

Sorry old faithful K1 time for retirement.

This Cat looks so good, i may have to change the brand for the 4wd!?

I was allready nearby, to buy a K1, when it came out, than i decided to stay with my dex, but now i think, i cant resist anymore....:wub

Actually, i like, they use some parts from the sv and sx on this car, i still have a nearly new svr and some spares, so i can carry some of the parts over, if i get one of these?

allot were running them at worksop, looked good and Danny took ftd I believe. had a good look round his and looks really nice bit of kit

gear box tops are the same rear arms are sv2 I think by the looks , front arms same, front caster block different
front inboard mounts same, new ball cups should never pop off

Does the motor rotate the same way still?!

The motor rotates the same was as the SX3 so opposite of a K1

As i'm realy want one of this Cats and i have to order from germany, i do have some questions, before i put the button to order...:)

Does the mounting system and cf strap for the shorty battery come with the kit, or is this an option? I couldnt find that in the discription?
Is it worth, or naccesery to upgrade to the aloy upper transmission housings?
And could someone please tell me, what parts i should order to carry as spares in my pit box, too?

This would be my first cat, so i dont have spares, exept a view from my svr, i saw, they could be interchangeable!?


Thanks in advance and

Alloy upper gear box tops worth getting
Shorty battery strap kit is an extra but only £5.99
Spares the normal you would carry for any car.
You will like the cat I've been running the K1 and if the K2 is an improvement on that then will be a great car.

I think you will find that the strap to mount a shortly in the transverse position is in the kit but to fit a shorty length ways is an option.

The front alloy upper gearbox top adds strength as the plastic one can break in a heavy crash.
The rear alloy upper gearbox top isn't really needed for strength but allows the rear shocks to be fitted on the rear of the wishbones.
The alloy front suspension pivot block also adds strength.
The Core RC Spring kits are very good and a reasonable price, normally kit pistons are good.

Looking at the kit set up for astro, the kit front springs are white while the rears are black. So the softest on the front and hardest on the rear?

Thanks for that infos!:thumbsup:

Some more questions did come up.
Do you change the internal gearing often and if so, what is a common internal gearing? Or is the kit standard a good point to stay with?
On the manual, the shock covers are listed as an option, are they worth to get, too?

Thx again and

No, see pics :)

Yes the motor rotates the same as all motors, the pinion will rotate anticlockwise when looking from the pinion end.

The motor rotates the same as any other motor. As in the pinion will rotate anticlockwise when looking from the pinion end.

Trick question I fell for LOL

[QUOTE=badger5;932267]I think you will find that the strap to mount a shortly in the transverse position is in the kit but to fit a shorty length ways is an option.

That's what I was referring to and the fella I was answering understood what my answers was.

HolyMoly, that will be an shoping list by ~ € 700,-!
How to explain that my wife....:D

I could declare it as my personal christmas present!:woot:

nope the motor rotates exactly the same in both cars....

In relation to the wheels the motor spins in the opposite direction to the K1.

There are other ways for you to put you point across, at the moment you're doing nothing for this thread. All understood what was meant!

:thumbsup::thumbsup:

Now you add a few extra words your comment is correct. How you and others answered originally implied that the motor needed to be reversed.
So as you say, there are other ways to put your point across. :thumbsup:

I've preordered mine, hopfully it arrives at the beginning/mid of next week!?

Did anyone got his K2 allready?
If so, how are the first impressions?

I've preordered the k2 hopefully it'll arrive tomorrow or Monday. It's my first 4wd so can anybody suggest a good stating point for motor turn and gearing. I run on a medium-large size Astro track and I gear my 2wd kf at 76 spur 24-25 pinion with a 7.5 motor if that's any help. I was planning on building the kit pretty much from the manual and then working from there but are there any essential additions/upgrades that I should fit straight away. Thanks Andy

Hi Andy, for Torch I would suggest the vented shock caps so you can run the shocks in emulsion set up, smoothes the car out over the bumps quite a lot.
The front alloy upper transmission housings a good to have for strength but not essential first off. I also use the alloy rear camber link on my K1 and KF2.

A 7.5 or 6.5 would be good motor wise, can't remember gearing but I expect something like a 22t pinion would be a good starting point for a 6.5.

Let me know how you get on, I'm getting mine delivered to where I'm working at the moment (Isle of Islay) and will build here. Look forward to seeing you at Torch and Newbury in December when I get home. :thumbsup:

Rich Roberts

Cheers for the info Rich, I've wanted a 4wd for a while and couldn't resist when I saw the K2 as it looks pretty cool.

i run on my K2 a 83T spur and a 21-22 pinion depending on track size
