2025 21.5 Pre-Pro SE buggy

[Charlie don't surf]

New XR10 G2 100A HW speedo, ROAR 21.5 HW G4r (until I hear we can run the Outlaw stuff anyway). Buggy feels super solid, should have a track report in a few weeks, but my bench setups are usually very close to ready to race so we'll see. I am going to share transponder between my 17.5 and 21.5 buggies which should drive the race director crazy lol.

Going to start with Blue XX front springs, 56,pistons, 35w 19mm, middle upper and inside lower, 30* with MIP bar, gumball fronts with RM2 inserts. Yellow XX rear springs, 56 pistons, 32.5w, SWB (because of the Jrx2 front arms), 2038 rear hubs, 3* 1 anti squat, 18mm ride height. 8mm hex, Gumball rear with stock inserts, 7" wing.

72/34 with the LRM trans, B4 slipper, motor at 47* with 30mm fan, Speedo set as aggressive (low frequency settings) but Blinky,, high frequency brake settings and only at 65% so I stay smooth and don't scrub all my corner speed on aggressive entry-

If the car is too tight, I'll lower the roll center some so it has more weight transfer and that hopefully is about it.

Could lose a few grams lol

However, this 21.5 car is fast.

The run up before the double was wet and slick, so we didn't bother with the double, which is .2 faster. Clicking low 13 sec laps which is really solid for a 21.5 blinky 35 year old car-

Tried a low roll center option but the car had way less center-off steering. So after 6 hours of tuning we went all the way back to what I started with...but with green front springs lol. When the track is fresh and watered for the Jan race I may have to go back to the blue springs...but other than that its good to go-

Looks good. Going to make any changes, ie more rotation?

Not until I see the layout and traction for the event. It likes to be driven hard and rewards you for it. I'm running the legal Jr2 arms which have a lot of flex and kinda get tight in the center if your not hauling...but it caries a ton of corner speed when you do without being hard on the motor (pulling 49a via speedo, 20456 RPM at 86f)

just saw this post so is this a factory prototype buggy?

It's prepped like an ex-factory car, and it's in line with what the Team was doing after the Jrx Pro was released (Jr 2 chassis, jammin front tower, material removed from chassis/trans case gold anodized hard shocks) and more. Just a really cool car to make a race car out of

Ran a club day yesterday as a final shake down before or big vintage event at World Of RC

Car was really good, TQ'ed the class in round one, played with some option tires in round two and didn't make better time, went back home with the girl I took to the dance in the A. Pushed my LiHV packs up to the legal 8.7v and my diff was barking because of the extra voltage, so I only pushed so hard against the modern cars. Took 2nd, could have won if I hadn't bobbled in a corner and hung a pipe.

Motor temps were low, car was free and fast, drives easily. Should be trouble next weekend. Fast lap in the A was 13.2 sec set by me (only vintage car) by comparison my B2 fast lap was 12.9 sec with a 17.5 system (also placed 3rd overall in the A with the B2) so other than more gear and more timing...it's good to go

Ok, so late race report. 2025 Tamiya World Classic at WORC.

Buggy was just as good with the new layout as it was with the shorter and mostly more technical old layout. Overall the only changes I made was to go up one piston in the front and down.one in the rear. Car was hella fast, I wasn't the biggest fan of the layout, it was overly tight and under technical...so it really wasn't fast, flowy or fun- but it was the same for everyone and beat the rock crawler section we had last year lol.

Dave McGewen was TQ, I was 2nd overall in qualifying his fast lap and my fast lap were within 0.01 or so from.each other....and as a multi worlds qualifying driver...he's way better than me. So in short the car was incredible.....and for those who know....it was 100% legal. That part was important to me.

I'll be running it again 1 Mar at our series race, track looks like it has flow, so we'll see what I can do with it there. Car is incredible. I suggest others that want to vintage race to look at this platform...it won't disappoint

New shocks day, thought the nylon spring adjusters fit this car pretty well.
