Holy! 55/57mm? Yall should mail me the tires you are running and i'll mail em back once they reach that diameter . Over here, most of us usually race new uncut rear tires with 2mm split for mains due to the high wear of our tracks.

With 55/57 diameter, are you able to complete 30 minutes final ? 1 hour final ?

With such small tires diameter I think the top speed is compromised, isn't it ?

There is almost no tire wear at Revelation Raceway and you can adjut your gearing for the smaller diameter tires.

Holy Smoke !!!

Do you guys still have the thursday night racing at revelation ?

Usually higher traction tracks have less tire wear and therefore you can get by with a smaller size tire. Keep in mind that most of the guys that do this are very smooth on the throttle and are not wasting tire by over driving the car.

Can anyone tell me what kind of shock pistons go in the front of the mtx-4.
1 hole or 2 hole white or black.

One hole white for the front and two hole white for the rear.

I´d like to share some findings when I built my first mtx4 kit. Hope these tips help new owners!
1) sets screws on page 11 for the 2 shoe speed are 4mm, not 3mm like on the manual
2) silicone use is mandatory if using the front diff with diff oil, not for spool.
3) the ball links of the steering rods need to be dremel if using the standard belt tension in the front
4) i used 1.5mm washers on the rear shocks lower cups to keep the shocks straights due to the 4mm shock tower
5) with the 24mm pulley, I dremel the graphite plate to gain more tension for the belt, and I used 2 0.75mm washers between the plate and the base to avoid contact with the engine mounts, worked perfectly and now your even most used urethan or rubber bands won´t be loose.
6) I used the rubber spacers that came with my servos to avoid the throttle servo to be in contact with the chassis.
7) the 3rd post I used is a mtx3 rear body post, screw to a small plate on one end, the other end is screwed to the steering post. now my 3rd body post is on the windshield, not on the hood.
8) I used 3x10mm caps screws for the engine and 3x10mm for the chassis engine screws, 2mm extra tightening.
9) waiting time for new ninja 12, yellow shoe and new super harder spring, 3 weeks from now

Good on you !!! Have a nice racing !!

no more night racing for onroad. We have night practice every Tuesday and Thursday and onroad racing every 2nd and 4th week.

Uhm.... I would bet you're using a Mazda 6 body if you have this problem (forget it... just seen the attachment you put). Did noticed that 3rd body post has an offset just to slightly move around their position? Double check it and correct if is installed in the wrong direction.

For a correct placement of the Stratus 3.1 body, you need to trim about 1cm of the front bumper. If not, happens what happened to you, all the body is displaced to the front.

Regarding the Ninja .12... good luck with the wait, waited for 4 months and seems that more wait is intended (ends of May, first of June - this is the last comment). Got p*ssed and bought a pair of Sirio Evo3 Sti... I'm not regreted with the change.

To all: take a second look on your engine mounts and check if any part of the crankcase touches with the engine mounts, when warmed, everything will grow-up and can drive to a distorted crankcase or other weird problems (some novas and Sirios touch slightly).

God damn that track must have some grip.

Hi Guys, just thought I'd give you a report on the STS D3R. First race the other night and finished in the top 3 all night to take second place over all.
Up against another MTX-4/ Sirio evo3, CD3 Pro/Sirio Evo3, Serpent/Mega and a FW05R/OS TZ. very happy with the performance and initial results.
Down the straight(approx 40m) it looses maybe 2 car lengths on the Evo3's, but has it all over the OS, but with some more dremelling and fine tuning, and at half the price, it will make a great club engine.

thanks, i have a d3r with some mods done to it, and my first race with it will be next weekend, glad to hear it works well
