TLR 22 2.0 - Page 7

I'm just wondering if anybody has seen Losi comment about raising the rear chassis under the gearbox?
I know raising the gearbox by 1mm was used as a tuning aid but comparing my old 22 chassis to the 2.0 the rear step is different it certainly looks to be raised up more than the previous 22 chassis. I have seen Frank Root comment in response to a question that raising the gearbox by 1mm is not needed on the 2.0 but nothing about a chassis change at the rear?

What does raising the transmission do?

And Paul, can I ask what pistons, spring and oil you are running in the 22 2.0?

Thanks

Hi Cremegg,

raising the transmission improves side bite and traction on corner exit. See here http://losiracing.blogspot.co.uk/201...2-and-22t.html

I've not got my shocks built yet and the few set ups I've seen are split between 2 hole 1.6 and 4 hole #55.
The only mid motor set up posted so far is Dustin Evans ROAR Nationals 3rd place with 4 hole #55's but this is for a sugared in super high grip dirt track - the same one for the worlds - not sure how that transfers to astro or grass?
The strange thing was despite the high grip Dakotah Phend won from 3 with the only rear motor car in the A final! So big win No.1 for the 22 2.0 first time out, but it looks like Losi is testing for a standard steering set up as Dakotah was running what seems to be modified RB6 steering bellcranks.

Thanks for that link Paul, explains it very well

I ran 55 40 holes pistons, 25 wt in rear and 30 wt in front and bury yesterday and the car went round very well. This is the setup I had in my old 22

I was asking about the shock setup because there are no setup sheets for astro as of yet...I'm sure there will be soon

Finally ready for the worlds

How did you find it compared to the old 22?

Oh and just a heads up I had a quick look at Martin's blog (Razer) might be worth addressing questions about shocks to Martin as he runs on grippy bumpy astro plus he has been running 2 hole 1.6mm pistons for a while now. Hi Razer

PaulUpton · #**127** 09-09-2013

mine ready to go

Cremegg · #**128** 09-09-2013

It's was very good to be honest....a lot better than the old one

Going to run it at southport next weekend and see how it handles the bumps on the back section

Here's my 22 2.0

Cremegg · #**129** 09-09-2013

Can anyone tell me if the exotek steering rack will still fit in the 22 2.0?

Never mind.....just seen the price haha

I've love the 1.6 pistons. I feel the car is less sensitive to the small bumps, yet still lands the big ones well, and has enough pop on the jumps. I stopped testing with four hole pistons quite quickly though, and I'm not really one to test a lot of shock stuff if I feel comfy with what I got. I'm really looking forward to trying the car now, with the new geometry, o-rings and shafts. Just the LF springs helped the handling a lot, so it should be superplush and easy to drive now.

I'm off to the worlds soon though, so there won't be any astro testing until maybe a sunny october day, unless the snow has fallen already.

I'll try to keep my blog more updated again in the following months:-)

Cool, thanks man

Can I ask a quick question too
Regarding the HRC & LRC toe plate

What do the degrees mean on them?

Eg 3.5 deg LRC

Thanks

That is the amount of toe in you get;-)

Razer · #**133** 10-09-2013

My car is ready for the Silver Dollar Raceway

CARB · #**134** 14-09-2013

3 degrees toe in and low roll centre, check out roll centre on google

Well I can now confirm that the rear of the chassis has been raised higher than the V1 Losi 22 chassis by aprox 1mm. Anybody wanting to use the old Cream mid motor weight will now need to run at least 2 degrees of anti squat, possibly as much as 2.5 degrees before the weight will clear the revised rear kick up. I've PM'ed Cream about the issue so no doubt a revised block will be sorted soon.

Yep V2 will be ready soon, along with the added m2 holding screw.

Frank's response on the 2.0 chassis (from RCTECH) So I guess its just a clearance issue.

Can Frank or someone attest to this, or is just another rumor?

3. 1 additional hole for the M2 x 8mm Front Anti-Squat pivot block.
4. Added TLR laser etching behind servo pocketing.

Everything else is unchanged.

i have an higher chassis of the 1.0 version
last year
i could not get the chassis to work either there was to much tension when i put it together in the back
just bought a new one and that was fine
my 2.0 chassis are both the same as the 1.0 rear
i tried to lower it but its to hard

My V1 chassis is the same as the one to the right in your picture with a lower step, in fact I have had two other V1 chassis and both were the lower type. Until I bought my 2.0 I had not seen that version of the chassis - the one on the left in your picture - so thought it was a change coming with the 2.0 but it sounds like it may have been a running change to the V1?

Is the new cab forward body available yet?
