Yokomo Bmax2 M

[mrspeedy]

I found the same as above . ... shorty longways has a nice flowing feel to the car .. also tried moving the shorty up to the servo ... needs work but the car didn't seem to loose any traction like this ...

Hi
Standard pistons №1 №2 №3 have hole diameter?

From memory. 1.1mm, 1.2mm and 1.3mm x 4 hole. i think I've measured these and posted abiut it here on bmax4 car thread. I'll check them again later.

Thanks Neallewis!

Finally got out with the bmax2 yesterday for a couple of hours on fairly high grip astro.

The setup i settled on was,

saddle packs (all ive got at the moment)
5k diff oil

front
40wt
1.6 2 hole pistons
associated yellow springs
20mm ride height

Rear
30wt
1.7 2 hole pistons
associated grey springs
20mm ride height

The car felt great, nice and stable and easy to drive. I need to have a mess around with roll centers and shock positions as that was all stock.

Question regarding people who run shorty packs. When you go from saddle packs to shorty have you had to change the dampening and springs much? I would assume you would have to go lighter because there is less weight in the car?

I'm still messing around with my setup for shorty .. got some copper weight under the lipo to bring the weight up to the same as saddles so not a massive change .. rear shocks work well on inner w/b hole, AE white spring, 35 wt oil and 2 x 1.7 piston .. and AE blue front spring 40 oil with 1.6 piston .. shocks leaned in on top ... works well with the lipo moved 1/2" off the rear stop too ...

Whats the logic in running shorty but adding weight up to saddle weight?

Is the position of the weight drastically changed like this?

I think aligning weight in the longitudinal direction is what does the trick. I also run a shorty and the Yokomo Europe weight plate underneath, and I like it better than saddles. Although I am not a good driver it just feels right, more reactive without the rear end becoming too loose.
I've got a full size servo with the ptx on the side, the rx and capacitor on top, and the esc right behind it, so moving the battery more to the front is not an option, but also not necessary at all.

Its keeps the overall weight the same so seems a good place to start from for setup .... Also if you use a lead sheet it will lower the centre of gravity ...

Really it is the weight position that makes so much difference ... you can definitely feel the lack of the big lump of saddles at the rear ... makes the car more flowing to drive ... doesn't seem to loose any rear traction either !!

Yup, ran the shorty down the centre once now and it was great. Exactly the same set-up but the car drives much better. Doesn't loose rear traction surprisingly... just stops the rear leaning over way too much mid-corner and helps carry the speed.

Huge difference! Definitely won't be changing back

English translation:

■ New design aluminum integral main chassis (select mid motor, the rear motor is possible)
■ Titanium turnbuckles
■ aluminum steering bell crank
■ titanium-coated shock shafts
■ Φ1.6mm X shock piston
■ Double-pad slipper clutch
■ Aluminum front lower suspension mounts
■ Aluminum Front Upper Arm Mount
■ Aluminum Rear Hub Carrier (0 degrees toe-in)
■ Aluminum Rear Suspension Mount

Has been announced yesterday.

Only difference with the V2 Worlds is :

- Rear alu hubs
- Shock pistons
- Plastic shock caps
- New (current) bottom caps
- Hex wheels

Great choice for those who want to buy a new car. Not a must have if you already running a V3 or a up to spec V2.

what do you mean when you say 'up to spec ver2' please?

I got the yokomo bmax2 mr ver.2 as my 1st buggy which is great but I haven't got any hop ups (I think you call it) on it. Is this what you mean, or any worth getting?

[skyaflake]

You don't need to buy the V3 FK in case you have the V2. It's only worth upgrading in case you have a (older) V1. The V2 is still up to spec and still worth every penny (or Euro ). I personally still run the V2 with some upgrades, it's a great car. Rock solid.

what upgrades do you have on yours, is it to make it look nicer or are they making the car run better?

mine is just run with all kit outta the box, even the shock oil is what was supplied with the kit

[neallewis]

Anyone know when the front alloy C hubs are due out?

[subucultcha]

already out by arrowmax

I prefer Yokomo over Arrowmax. No estimated release date for the Yokomo hubs. Just wait when a date will be announced. Probably soon, as they product is already production worth.
