I've went away from using the ball diff and finding the gear diff is alot more to my liking, even in the wet. A good few at our club have went to this now.. however the ball diff is a good option to have in your box.

No, when i spoke to Tris this was not in the pipeline to do, maybe they may in the future, who knows.
However for £250 ( plenty of model shops are priced around this region) you get a very competitive car for mega high grip. Add £79.99 for the conversion and you have a superb all rounder for the outdoor environment.

Start out with shorties and you do not need to buy two types of cells, adding weight to the shortie gives the same desired effect of running saddles.

You have to run a shortie when in low grip mode, with the motor being shifted back 21mm something has to give and the shortie gives that clearance to do so.

I also have both cars, KF and SV2 and used either for each condition. However i much prefer having the one car, one set of electronics, and the option to convert that car to a high grip animal for the indoor season.

Something to bare in mind, at stotfold it is a singular surface, when the grip is high, 100% of the track is high. On a multi surface track like Kidderminster or Southport the KF is manageable. However the low grip conversion comes in to its element when you hit concrete, cobbles or tarmac - the car pushes slightly, whereas the KF will want to fishtail.

You can run shorties in both the KF and the KFLG conversion, if you wish to run the same weight as a standard KF with saddles then add some weight in front of the shortie.

If schumacher are not carful they will turn the KF into the SX3, a very nice car but a pig to set up which will put people off. Simple is best and thats what has made the SV2, K1 and KF so popular.

How will they turn a proven car in to a car that is a pig to setup? The stock KF is a huge success, and well deserved as it is an animal.
The low grip conversion simply lets that mass amount who have bought the KF for indoor racing bring their car outdoors and get it going alot easier - I see that as doing us all a favour?

Dont get me wrong I also love my SX3 and K1 but i do prefer the K1. as its simple.

The main change to the car with the low grip conversion is removing weight from the front end, shorties are the counter effect of doing this as more space is needed at the rear of the car to house the motor / layshafts.

There are some very competitive prices for a BRCA legal shortie lipo at the moment, both LRP and intellect have fantastic prices.

Also to keep in mind, the current trend in 2wd offroad is the apparent need for two cars, one low grip, one high grip.

Put this in to numbers;

Set of electronics ( priced up my own equipment, LRP, sanwa, savox) excl batteries £335
KF £250
TTL £585

Set of electronics excl batteries £335
SV2 £195
TTL £530

To have both the KF and a SV2 it would total £1115

To buy the KF, with a low grip conversion, electronics, PLUS a shortie it would total £715.

A saving of £400 and you get a car that is able to work everywhere. No brainer??

Im running the low grip layout with shorty and ball diff. I tried it at RHR last night and prefer it there too so pretty sure it will become my main car now. The shorty in the standard layout is poor in my opinion, but with the new layout I think its excellent in high and low

only doing oople series and local rhr regionals so only southport to cope with ;-)

im lucky enough to have all my cars fully ready to go by flicking a switch and selecting the model, cost has been done!

cheers James that's what I was trying to ask/get the answer for

[Kelk]

The build is done bar the shouting (alignment, electrics to go in, aerial tube) and the quality is again excellent on the build...



I know it's a 21 mm move but it looks huge compared to the standard.

The only questions / comments I have are:

1) why does the instructions state that the way to change a battery is to remove the side pods? For those that are already using it have you dremeled away the side pod to give further access or just leaving cells in the car to charge (implications at BRCA event?) or what?

2) why have they not accommodated for the fact that the motor has moved back and put a 2nd hole ot access the motor positioning screw in the side pod? I guess it's reamer time right?

If I've been a numpty then please do say

A couple of other pics...

Showing the "lack" of aligned access...



Side view...



So for those that are already running with this - any tips or advice?

Thanks

I agree but as I have all the cars above but no shorties, I stand to be out of pocket. If you look on oople u will see that I designed the KF well over 12 months ago. http://www.oople.com/forums/showthread.php?t=112797
I guess im going to have to go back to the drawing board and design it again so it can run saddles with the new chassis lol

[jonathan may]

ran my low grip chassis today at mendip off road track was amazing loads of rear grip and steering and took the bump better then standard layout I felt

the low grip conversion uses a 103t belt, the shorty conversion uses the 117t belt

[CARB]

the set up is on the Schumacher site set ups etc, it was carrying 96 grams of extra weight under the battery and beside the motor , rear motor configuration as we'll

[dobber]

What modifications are needed to shell to the original shell are required? Im very tempted to get the kitbut there are no shells for the low grip anywhere. Is it a case of a cut a hole so the spur doesnt foul the shell, if so will it be ok to run it as it has an exposed spur? Has anyone cut their original shell, if so pics please

[wrighty]

I warmed mine up and pushed my thumb into it to create a buldge where the spur is

Are you adding any weight anywhere with this configuration James?
