KF Stadium Truck...

[Adam F]

Fancied a bit of truck racing, but as no Schuey truck is available I thought I would convert a KF to stadium trim using some odd bits I had to see how it went..

Ran it briefly for the first time last week and its ballistic... :D

[cmgreen]

Looks good, what did you use to convert it?

[Adam F]

Its basically TC02T shafts & wishbones that have been re-drilled and narrowed on the rear, with the fronts re-driled and spaced to fit the schuey bottom plate..

Rear body mount was some random touring car thing that was narrowed to suit and fronts are TC02T re-drilled and in place of the front shock tower fasteners.

Pretty simple, but drives awesome!

[cmgreen]

All ways think these are the future instead of those sc things

[NeilRalph77]

ST are way way cooler than SC I don't know how anyone could think otherwise!!!

[bretts]

Chuff me, that's a lot of ribs to remove on the front tyres!!

Where do you run?

Any vids of the heats?

[Adam F]

I run at Silverstone, so its indoor astro... very high grip.. It really needs another row off as I had to limit the steering to 45% throw!!

I've only run it once at the winter series last week, but it was already 3 seconds faster per lap than everyone else... and that was without actually trying to get it set up.. Don't think there was any video unfortunately.

And yup, ST all the way!!

Love this, it's about time Schumacher produced one of these!

Totally agree!!

[Danosborne6661]

I'd like to see a KF short course :)

[jimmy noke]

I'd like to see the schumacher sc in production

[schmacher]

i just want longer rear shocks so i can finish my svr truck properly

[Adam F]

Ran the truck again tonight... I love it... :wub

On a sub 18 second lap I was half a second slower than with my KF and consistent, pretty good for an ST!

I thought it needed longer shocks, but happy with it as it is.. :D

[Matthew Moore]

Can you post a full list of parts needed to convert the KF and pictures of any modifications. I'd love to do this to make a fun truck for practice nights 😃

You need to be going quicker with your KF :p

But seriously, your truck last night was awesome, first time I've ever seen a truck that looked like it really handled at Silverstone.

[Adam F]

Parts list is earlier in the thread, I don't have part numbers as such as I had the bits laying around..

You're right Nige... need to stop trying to run two cars in one night and concentrate on one or the other!! :D

[knighthawk]

I'm looking to do something with either my KF or KF2

Are the dimensions of the latest stadium trucks the same, i.e. Do they have longer chassis etc

Cheers

According to the following listed specs, the wheelbase is close.

KF2
http://www.racing-cars.com/pp/Car_Showroom/Cougar_KF2.html
Wheelbase: 285mm

Associated RC10 T5M
https://www.teamassociated.com/cars_and_trucks/RC10T5M/Team/specs/
Wheelbase: 289mm (11.38in)

Kyosho Ultima RT6
http://www.kyoshoamerica.com/ULTIMA-RT6-Stadium-Truck-Kit_p_22829.html
Wheelbase; 290mm

TLR 22T 2.0
http://www.tlracing.com/Products/Default.aspx?ProdId=TLR03004#prodFeatures
Wheelbase: 11.3–11.41 in (286–290mm)

XRAY XT2
https://teamxray.com/xt2/2017/en/specs/
Wheelbase: Adjustable 289-294mm

[Typpo]

Based on the kits above, why is the 2.2" wheel diameter used over the 2.8"?

[Adam F]

Just to note, if you run the Team C wishbones up front it ends up around 6mm longer, so around 291mm ish..

Still got mine, in bits waiting for a reason to put it back together :)

The below is my highly modified Storm 2000 released around 1992/93, this was probably Schumacher's last racing Stadium Truck! With the Storm 2000 you could have it Nitro or electric :thumbsup:

It has a Mugen ST body shell to make it more competitive when I was racing it again from mid 2003 up until around the end of 2005 as the original Schumacher truck shell was massive and slowing it down..

:thumbsup:

[Thomas B]

Thinking of building a truck ont of a KF2 that I have extra. Is there any other brand of wishbones that can fit KF2? Anyone now dimensions of rc10t5 arms?

[schmacher]

kyosho rt5 or 6 arms and driveshafts should work..front axles too

[Typpo]

At the diff output side, what is the diameter of the Kyosho driveshaft cross pin and ball?

[schmacher]

i believe they should be fine..i did use hpi driveshafts(firestorm i believe) on my svr stadium truck...losi use to use the bigger ball on their driveshafts

[Danosborne6661]

I imagine short course arms/driveshafts would be easier to source to convert a KF2 to a stadium truck? What about some of the real cheap Team C/Ansmanns or even the Hobbyking shortcourse truck as a donor?

The stadium parts don't seem all that easy to find!

[Adam F]

Just use the TeamC TC02T/Hyde... or Ansmann Macnum bones, shafts etc...

Loads on eBay cheap and worked well on my KF ST.... see first post...

Bit expensive trying to use Kyosho parts!

Oh and a ball diff helps take the strain off the belt... I have one for sale if anyone needs one :)

[stuey]

How difficult to do were the mods Adam? I might be interested in doing this conversion.

Dead easy... Just need to drill out the Team C arms so the KF hinge pins go in and then space the to fit the KF bulkheads.

[stuey]

So its a matter of drilling the wishbone inner hinge pin holes to match the Schumacher pin diameter, and spacing to fit the bulkhead gaps. I am guessing longer turnbuckles will be required, what about the outer hinge pins, bearings, front axles, rear hexes to match the driveshafts? Any brand of wheels you would recommend, along with a bodyshell?

Cheers :thumbsup:

[Danosborne6661]

This is way too tempting! Always loved stadium trucks, someone delete this thread before I empty my wallet on a 2nd KF2 :p

Other than your 2x links there, anyone else looking to convert will also need longer turnbuckles and then what wheels and bodyshell have you used Adam?

EDIT: Just realised I asked the same thing as Stuey.

If bearings, wheels etc are needed then perhaps a complete donor is worth while?

[Adam F]

Mine was a complete TCO2T, so basically used the complete corners with links/hubs etc..

Could have used the KF hubs etc, but had the team C bits all built up...

Same for the wheels and shell, although any ST wheels would be ok and I am sure there are better shells.

I would say the complete donor kit would be the cheapest option..

How did you get on with the car?

[Thomas B]

it went beyond expectation. Did not test is so mutch. Drove new KC mostly of the day but it was good and above al it was very fun to drive. Going to race it on sunday.

Thank you for uploading the helpful pictures. Based on the pictures, the ball of the driveshaft appears to be about one millimeter narrower than the comparable part of the stock Schumacher driveshaft.

Is there greater play with these driveshafts in the diff outputs than with the stock Schumacher driveshafts?

Also, is the diameter of the cross pin 2.5mm like the Schumacher driveshaft or is it thinner (e.g. 2.0mm)?

[Adam F]

Be careful of the belt if using a gear diff or a tight slipper..

I ended up with a ball diff and ran the slipper a tiny bit looser then normal.

[Derka]

Do you think the Team C bits would work with a KC?

[AmiSMB]

I would expect so as the KF and KC can use the same wishbones and the front end is exactly the same.

[AmiSMB]

Here is my conversion so far.

Some of my notes:-

Front wishbones spaced using shock plastic spacer.

As I only have Durango 14mm hex wheels to play with I had to 3d print a 8.5mm 12mm to 14mm hex converter for the front wheels to fit. It had to be 8.5mm width to get enough clearance away from the steering arm ball stud.

I have used the KC front wing mount as a body post and the team c rear mounts from the Hyde screwed directly into the KC shock tower.

Standard Team C Hyde links have been used and these are not turnbuckle types that can be easily adjusted :(

Using a position 4 layout and will see how it goes.

[Typpo]

Thank you for posting the pictures and details.

At the diff output side on the driveshafts, is the diameter of the cross pin 2.0mm or 2.5mm?

[AmiSMB]

2.5mm pins in the end of the dogbones. Tested earlier and it is really great to drive!

Thank you for verifying the measurement. Glad to read it drives well.
