I got a set of Great Plains weights from Robs RC Hobbies for $6.00. But I think Hobby People has them as well, they go into Helis.

Need some gearing help. Running a brand new Reedy Sonic (new version), and I'm getting pulled on by a B5M Lite in stock (red can Trackstar), both cars have the same gearing 69/33. Gearbox internal ratios are the same correct? Both motors have 30 degrees of timing.

Certified hand built Schuur Speed 17.5 with high toque rotor. 42 degrees, I just talked to Ron Schuur, and I should be running a 72, 32, with the certified motors. I have a regular D4 in my 22T 2.0 with 50 degrees of timing, and it feels like an 8.5. insane.

both very good cars. I came from a b5m lite and enjoy the quality and performance the yz2 has. Fit and finish is excellent.

If you are running on astroturf or carpet, the YZ-2 is an outright B5M killer. I used to have a B5M and also the Red Workshop low rider gearbox but should have gotten the YZ-2 right from the start. I don't know what cars the various manufacturers will release after the worlds, but none of the currently available kits come close to the YZ-2 in terms of quality or performance on artificial surfaces. With the B-Max2 gearbox inside, Lee Martin won the European title on a real dirt track with Pro-Line holeshots. I'd say the car has more potential than most of us will be able to exploit.

Default y-max

Are people running bmax4 rear arms on their y-max's?

I've noticed the 2 ymax setups on petit, both using standard rear arms, lee's and randy's.

I've only ran my ymax once, during a race meet, and didn't feel planted and bit tail happy compared to my b5m and serpent. Anyone got anymore setups for medium traction clay?

I have been running bmax4 arms on the y-max. Really stable setup but does take away a little steering. Probably going to go back to the yz arms to gain more entry steering.

Brand new for the Yokomo YZ-2. Grade 5 titanium axle from Lunsford Racing. One piece design. Lite and efficient. Part # 7080. Made in the USA.

I've been using these for a couple weeks now . Perfect fit and finish

The two cars are really great in the right hands. Both have their strengths and weaknesses. For me personally the YZ is leaps and bounds better in quality. I put the car down for political reasons otherwise I'd still be running it. The yok is easier to work on and make quick setup changes between battery packs. The corner speed is like no other. You won't be disappointed if you decide to purchase one.

The B5M was easy to go fast with due to the fact that at most tracks you have 100 B5's to 1-3 Yoks if you're lucky. Setup help at the track is greater where most yok guys either get frustrated at the track and don't test things or wait until they get home to ask questions on here. There is starting to be a bigger core group with Randy Pike coming aboard. I think MarkA was born with a Yok so he hands down has the most wheel time of anyone on this board😊
The new bmax conversion works wonders from what I hear. There is more aftermarket support for AE due to the fact it is more widely available. But I can tell you that 85% of aftermarket parts are for show only. If more hobbyshops carried the car you would see a bigger following. This is just my view on things. Do what makes you happy and remember we do this for fun😁

Can anyone please mic the flat and round part of the topshaft? I am working with Ray at Speedy's Racing Parts to get a proper slipper eliminator for this buggy. I don't have calipers unfortunately.
The buggy was so nice and easy to build.

If you don't run on astro or sugar tracks is there any advantage to running the YZ-2 over a BMax II?
