Ahhhh, so if I put a Schumacher (or other third party) pinion on with the Tamiya spur things should calm down? Perhaps I ought to try the B4 spur too eh. Does anyone know if they go higher than 87t?

Are you limited to just the 17T pinion? Are other chassis allowed in that class? Thanks.

Nice pics Vin and Sensory-O! Keep em comming!

[sosidge]

What sort of ride height are you getting with those DF03 dampers? Looks pretty high in both those pics, I wonder whether the Black CVA dampers may actually handle better even if they don't have the "bling".

For my tastes the CVAs work OK over everything except the big jump landings and coming off tabletops off-power when they just bottom out. The actual handling balance and normal bump handling with them seems good.

I think I will also be waiting until the DB01 shock set comes out, can't be bothered with the hassle of trying to source the 501X spares as by the time I get them the #54028 will probably be released anyway!

[DCM]

I might just knock up a taller shock tower and be done with it me thinks....

CVA Shocks

Scrub what I said above from the record.

I am totally fed up with them this evening!

No doubt it is the pistons to blame, but while the Durga suspension feels decent on the bench, it just isn't working right (for me at least) on the track.

Experimented with a front roll bar tonight - and ended up with MORE steering and a lot more stability too!

It's not supposed to be like this, so obviously the CVA dampers are allowing the car to roll far too much in the corners, creating loads of strange handling as the tyres unload and get extreme camber on them.

Had a quick blast with a friends 501X - same tyres (although newer), same sort of setup with one-way and camber, but it was SO much more secure on the track, must be the dampers. Hurry up #54028!!!

Otherwise had a nice evenings racing, thumbs are getting there, Durga will be soon enough!

There's no limit to the pinions. I'm currently running a 19/91 combo. Motor temp is warm to the touch. May come back down to the 17. As for classes there's a whole bunch. Classes include the 19t Baja 1, mini rally, tamtech's and wrc rally - all offroad!!

I tried the stock shocks, there seemed okay, not great, but okay. My hobby shop is trying to source 501x parts but like yourself am having problems getting (in my case) shock bodies. So for now I went with the DF03 units. They're a bit better. Indeed the droop in the rear is huge. To help with the droop/weight transfer I added 3mm front and 5mm rear spacer under the pistons - for my carpet setup. The front and rear arms are level with the driveshaft just above. Overall the rear arms will hang some 7-8mm from this resting point. Car is starting to handle a lot better as the rear feels more and more planted. SO

how do you manage to fit in the 19pinion on the sport tuned? i thought the short 17pinion in the kit was made for silvercan/sport tuned?

[Sensory Overload]

I wasn't aware of any length problems as I've only fitted the black can at this point. With that said my 48p losi pinions work fine.

[Toonz]

then i guess the 48p losi 19pinion should have the same height as the kit 17pinion. if you don't mind opening the motor cover to make a comparison

i really have no idea why tamiya isn't making shorter pinions for the black or motors with a shorter motor shaft

the rest of the hop-up pinions from 18-21 will not fit into silver/black can as they are longer which is also meant for longer shaft motors....

why tamiya why....................

[sim]

All else being equal, longer pinions fit more precisely to the centre of the motor shaft. The long pinions were meant for the 501X. The 17T one is a one-off to make the Durga somewhat silvercan/blackcan compatible (although what a horrible ratio to have chosen for those motors).

[Toonz]

HPI has 15T silver can and it will fit the 17pinion good time
just peel the sticker away and everyone will think that this is a mabuchi silver can....and the difference is.......just faster

[sim]

Hahaha. Running a HPI motor in the TAC. I think you will not only be disqualified, but will be caned in public.

[Toonz]

and then ban from the track for the rest of the year

[Vin]

I finished building the chassis today and I added some spacers to the DF03 Alu shocks. It all looks great now! I added 5mm to the rear.

Should the car be lower on the front or should the chassis be parallel to the ground?

Note that I'm using the 5mm (under the rear pistons) spacers to correct droop on a carpet setup. 3mm in the front seem to level out the car. cvd's are near/slightly above level. Car feels good. So
