Default Exotek EXP

hi all -

i just wanted to post some good feedback on the Exotek EXP chassis. i had tried the chassis a few weeks ago in modified tc, and have continued to test different modified setups with it. the chassis is SUPER light -- so watch out when making weight. it weights only 76g while EJ's chassis weights 87g (both are still lighter than the stiff lipo chassis). the chassis supports an alternate servo mounting position, but i didn't not use this position. due to running on a clockwise layout there was a fair amount of drag on the little nub for the servo mount.

the handling of the chassis was comparable to both the stiff lipo and EJ's chassis, but there was slightly more roll/flex. this roll/flex actually works to your advantage of lower grip surfaces, or can be stiffened with the use of a medium (or harder) top deck. my previously posted modified setup worked very well on this chassis once I ran all 8 screws in the soft top deck (i only had 4 screws within a second modified car running the stiff lipo chassis).

i'll hopefully be able to post up some pictures today of the chassis all mounted up.

I put the exotek chassis on my car that I usually use for the slow classes as it only had an original 6 cell chassis on that one before. Fortunately the class I'm mainly using it for right now has no weight limit .

I just received the "EJ" narrow chassis in the mail yesterday. I plan to use it on my newer car that I use for super stock and mod on rare occasions, but might save it for the carpet season. That graphite just looks too pretty to kill right away on the asphalt.

After one day at the track, even though it was only 21.5 blinky, the nub sticking out of the exotek for east/west servo mounting, is showing a fair bit of wear. I might go back to the north/south servo position and just chop that nub off. Because of the location where you have to connect the servo link to the bellcrank for east/west, it acts like a lever and doesn't require much force at the wheels to rotate a normal servo saver. It would mean it's also much easier to strip servo gears if you opt to not use a servo saver like I did, because there was simply too much slop with the ones I have.

I'm not great at picking up subtle differences in handling yet and I changed a bunch of things at once when I switched the chassis, but I can say it feels like a completely new car now. It was pretty decent before, but now it's an absolute pleasure to drive. If someone was looking at me when I put it down for the first few laps, they would have seen the most ridiculous grin in my face . It's almost unfair how good my car is now compared to the others I'm racing against. It's a totally legal car, but I expect to be accused of cheating this weekend. Some guys thought I was cheating before when my car weighed around 1500g

hi all,
last weekend we had the largest european touring car race in Andernach.
I could qualify as 3rd in the Prostock division, but had a little pitch in the finals and was only 8th.
Here is my setup from the ETS final in Andernach.

Michael

Does anybody know the height difference between the standard carbon camberplate en de aluminium ones? I only have the carbons and I see many people run the alloy's with totally different spacers for the upper link.
thanks, Danny

Congrats on the effort Michael. The Andernach track looks amazing. I hope to be able to race there some year...

Please take a look if you need something different than Larry's usual setup. This setup had a lot of corner speed and was very easy to race with. On the practice day after our Region Two regional this setup was only 0.1s off of Hebert and Haynes (it was all car, not me...)

hanulec...were you running swaybars in this setup? Also how did you measure the droop?

No bars
droop over ride height. 2.5mm front and 3mm rear is the usual starting place

They just slap together with no leaking...
The gears lost a few teeth but didnt completely strip, i have 1000 gear diff oil in it i heard that was the best to put in it from other team drivers. Car was going good untill it just span round. Struggling to find a yokomo geared diff in UK to be honest or i would have got one. X12 lrp 10.5 motor

Picked this gear diff up a while ago and never tried it. It feels kinda notchy. Is there anything I can do to make it smooth or do I just run it like that? I'm going to give it a shot in the rear.
