Looked pretty good on the track yesterday aswell!!!

How does the CR2 feels, handling-wise, compared to others 2WD?

I must say the car is

[V-Rossi]

It is like a mixture of the 'agressive' feeling of the S2/B4 and the easy to drive and forgiving feeling of the X-6 and XXX-CR. Out of the box it was almost as fast as my S2 after a season.

As the car listens very well to set-up adjustments, you can easily make the car very B4-ish or X6-ish, making it suit your driving style or track.

Thats interesting rossi... I found those cars to be the opposite... B4 laid back and almost too easy to drive, whereas a CR suits me as i find it more aggressive to drive? I fully intend to buy a cr2 at some point

Strange
The thing I like most about it, is its predictability: you know what the car will do and when and how much it will steer after a few packs. If you come to the Kampenhout GP this year, you can have a go with mine.

well a wile ago sombody gave his in a loone to me for the players .
and as I havent driven a 2x4 in ages it whas quite a serprise .
the car whas great to drive and engoide my time using it at the players .
I even made it into the players event and ended 13 place overall with it .
so I can confirm what V-rossi is saying the car is the max

Here's my CR2 complete with B4 body. I've tried all the other bodies and nothing comes close to fitting as well as the B4. It goes all the way to the back unlike the Losi body and looks excellent.

When will i be Abel to order the motorplate and the idelger mod?

wont be long now bbq, pm oldtimer

[fastinfastout]

is the idler gear mod run on eccentric?

wondering if you can use a 75 spur

[tony12795]

You can only use a 78 spur.

We are still testing the motor plate.

[bbq]

i have hade some problems indoors with what feels like torque steer on my RHD.
I had the motor plate fixed to the chassis but it didnt give the same flex in the chassis
left to right and this was a probobly what made it feel like this when you punch it hard
out of the corner and when breaking hard.
I and a friend have done a new chassi fixing and it got rid of that problem and the car feels way more balaced right away.
My friend has done 2 new post the go all the way up so i dont need the plastic
extensions up to the plate.
Sorry for the crapy mobile pictures

I have been playing with the same idea, because of the left/right torque problem with the brass motor plate brace. Don't think that your solution will reduce torsional flex much, but at least it's the same left and right.

I also have been playing with the weight distribution of the car a lot, which imho makes it a lot better, I will post some pics after the petit RC race next weekend.

it was more calm on power in the sweper on to the stright we have at the club

[OldTimer]

I would guess the aluminium chassis will sort out some of your issues BBQ what you have come up with is what i used on the S2, but using part of the gearbox casing rather than using posts. Btw is indoors track high grip ?.

Re the motor plate & idler kit, still currently on target for the end of this month early next month.

[bbq]

not to much grip but it did make the car feel more calm and more stable.
and it might save the gear box when you land on the rear tower.
i have ner done that =)

How about putting a second hole in the motor plate so that a hyfradrive with 84t spur can be used? Smaller spur gears cause fouling between the idler and the hydradrive casing.

The hole that locates the idler post is countersunk on the other side of the motorplate (otherwise the motor would not be flush to the motorplate) and a extra countersunk hole so close to the other would weaken the area as there is not much cf left.

I choose the 78t as it is the kit spur and its what most people use, i am in the process of getting some 78t hydra drive spurs made. Also using the smaller spur allows you to move the motor more to the rear of the car.

And as you point out as a 78t spur is about 1mm smaller od than the hydradrive casing you would need to shave / dremel off half the width of teeth on the idler, so the hydra casing does not rub against the idler gear, but as the idler is over twice the width of the spur gear this would not cause a problem. But this only needs to be done if your using the hydradrve.

If you just using the two pad slipper then there are no extra mod's required.

just doing a rebuild now and some plonker has put an 84t spur on my car!!
