Does any of you lucky builders know what size the flywheel is, or could measure it for us waiting guys? Thanks!

Has anyone tried other clutches on the DNX408 to check if they fit ok ? Such as complete MBX6 one, or M2C one ?

M2C 4 shoe weighted and the 3 shoe fits. You just need to make sure you shim the collet so that the flywheel is more center on the chassis opening. The original M2C 4shoe non weighted requires less shimming so it's better option. Also the Aplus/SSTech adjustable fits you just need to make the same shimming. Again with 34mm flywheels it makes life easier if you dremel the chassis opening a bit especially if the starterwheel on your box is a bit on the bigger side.

Looking for a good Set Up for US style tracks so I can fill the diffs and keep moving? Or is everyone following the Kit instructions?
7-7-5 is OK or 10-10-5 and go from there.

Need about 1.5mm of washer or as Jaf used, a spare xray pad which was 1.5mm iirc.

Lower steering arm did seem a little sloppy i kept nipping it up today. My main problem was i stripped the plastic steering servo arm. Used the standard ace horn which promptley snapped. Aluminium horn will be ordered this week as well as backing off the servo saver from manual a little.

Apart from my steering problems car felt good, jumped very well, plenty of turn in and on power steering. Needed to up the oils from what i ended up running and fettle with dif oils. Just wish i had some more track time.

Front and rear is a piece of cake, but the center is a bit more difficult. On the Durango page, they show you the enter diff being removable by just taking out 4 screws, which is patently false. The engine's carb is right over the aft center drive cup, so you have to pull the whole engine out (4 engine top screws + pipe mount screw) to get to the diff. Mind you, that's still fairly close in terms of number of screws to access the same component on the K-car.

Can't wait to build mine over the holidays

Default 19 second lap indoor med/high bite clay track set-up

Here is my initial set-up that I have for a Medium to high bite average size indoor clay track. I would guess dimensions to be 120 x 60. 19 second laps.
This track was Delta R/C in Antioch California. Temps were around 50 degrees. Car felt very stable with lots of steering. (This was what I came up with doing one practice, 2 quals, and a main and starting with my Worlds set-up. So more will be done in future weeks to refine this!) :-)

Front shocks 6x1.3mm / 600cts, Red spring
Middle hole on tower, inside on arm
Front camber-link Middle hole/ inner row on tower
Hingepin spacer behind front arm.
Frontdiff 15,000cts
Camber -2
Height 27.5mm
2.1 swaybar
+1.5* toe out
10* caster blocks

Centerdiff: 12,000cts
Std Spur, 13T bell

Rear shocks 6x1.3mm / 600cts, Green spring
Shock Middle hole on tower and outside hole on arm
Rear link center hole on hub, inner row one up from bottom on tower
0 deg rearhubs, hubs centered
Rear arms all the way forward
Reardiff 6000cts
Camber -3
3-2 toe/kick-up insert
Height 27.5mm
2.8 swaybar

Alpha Z852 with Alpha 0801 pipe, Ballistic batteries 2500 lipo flat pack, Ko Propo RsX servos, AKA Enduro tires S (These were the only tires I had glued and ready as I hadn't planned on going racing, S Gridirons I think would have been a little better.)

Ryan, thanks for the setup on the indoor.

Any of you guys have play in the rear hinge pins? I put the 1mm spacer and then the 2mm spacer in and it has a pretty good amount of play. Needs atleast 2mm to replace the 1mm. If so, what did you use as a spacer?

This is step 12 in the manual.

Thx

Thank you Mazzinga! Hey, that's pretty big - might I ask if you are sure about it? Did you measure it with a caliper or did you find the info on the net? Don't get me wrong, just want to make sure, I ordered the car and want to get an Ascendancy clutch for it beforehand and wouldn't want to get something it will not work Thanks again!
