DNX 408 initial thoughts...
Finally finished building my DNX 408, not had chance to run it yet, but initial thoughts on the build.
1st off, very impressed. Everything fits very nicely, super close tolerances on everything. Only gripe is the fiddly throttle / brake linkage setup. Anyone else any thoughts on this ? The ballraced throttle linkage which mounts onto a 'plastic' extended arm is the only real gripe I have with the car. Even with the throttle end points set properly, the plastic arm bends around quite a bit when engaging the throttle. This part really should be aluminium as it's pretty damn important. Just looked on the Durango site, but no sign of an alloy part as yet.... Apart from that, the rest of it looks quality.

Hi Andy,
I also recently built my 408 and all though its a complicated throttle/brake setup, once the time has been spent to get it configured correctly, its very effective. the only slight bending I get on this throttle link mount arm is when the brakes are being used (which wouldn't matter) opening the carb the mechanism works just right.

Hi Chris.
It's certainly an elegant setup, I have tweaked it so it's set up just right, I don't get much, if any flex on brakes as effectively there is no force applied to the throttle linkage on braking. On the throttle linkage everything is free and smooth, and I'm only opening the carb just enough, but the arm still flexes more than I'd like. I'm sure it will be ok, just seems like the arm should have been aluminium though !

it's been posted on an american forum by someone from durango that there will be an aluminium post for the throttle co-ordinator.
i think the car need's quite a powerfull throttle servo, i've had to set my epa a bit deeper than i'd realy like to get the brakes i want, other than that i'm super happy with my 408.

Cool if an alloy one is in the pipeline, then that's good news.
Chris, can you confirm or deny ! Apart from that the rest of the car looks bomb proof !

I've not started at Durango yet (still working out my notice at previous job) so I know no more than you guys, but I have also read the same statement on RCTech regarding the Alu option part.

my initial setup of the car I am seeing that the brakes are stronger than my LRP car and ive had to reduce the EPA a bit. I am using some LRP fuel tube currently around 8-9mm long, its a bit thicker walled than the Durango fuel tube. brake feel is very driver specific so play around with the length and material used here to get the right kind of feel you like. another thing to note, ive often found that strong brakes rarely lead to a faster laptime, and certainly not a faster race time, consistant brakes will get you round the track faster and more likely on the currect line

i think i just need to fine tune the linkage, the throttle return spring was packing on sunday at ndor, i altered the length of the tie rods and moved the centre point on the servo, it's not too far off now, i think i'll take a few loops off the spring and give it a stretch.
i've never liked super power brakes, it upsets the car too much, i much more prefare to coast into the corners.
