is that the first convertible bmax2 MR with the plastic chassis.....I didnt know you can still buy them.....

on a side note, can you use the v1 mid plastic chassis on the version 2 and 3 bmax2?

yes, you just need this if you have a V3: http://www.rccarshop.co.uk/index.php...-bulkhead.html

If you want to use the v1 plastic chassis, you do not need the triangle piece from the v2 chassis, that centre mounting hole is in corporated in the plastic chassis.

If you have v2 or v3 kits, to run the v1 plastic chassis you need:

B2-002MR - MR/RS Main chassis
B2-002F - Front chassis/front bulkhead (lower plate required only if you have the V3 or Worlds chassis)
M3 x 10mm screws and M3 plain nuts, 3 each to mount the front chassis plate, but no reason not to run M3 x 12mm screws with M3 nylock nuts.

Hope that helps.

I've had the lying around in my loft for a year or so,so unsure if still available,but like neal said buy plastic chassis separately.just returned from its first outing at York and I really am speechless.

Putting my V3 together now. Has anyone else noticed some side to side play in the diff? (I'm installing the optional ball diff) I guess I will have to go out and pick up some shims tomorrow and shim it out.

neil_p · #**907** 11-01-2015

Yeah there is some movement with the diffs in the case. I cannot remember what thickness I used to shim it out but the inside diameter is 10mm.

I also shimmed out the rear axel washer (pin type wheels) front axel (AE type for Schumacher wheels) and steering bell cranks (Yokomo aluminium type) as I don't like the movement in these items from standard kit build.

Ball diff is extremely smooth and it took 1 10mm axle shim per side to take out the play. I was putting together the gear diff and it seems very "notchy" with 5k diff fluid, do these take some break in time? My Schumacher diffs were always very smooth when built.

skyaflake · #**913** 13-01-2015

It shouldn't be, but a ball diff just feels smoother. Does the gear diff feel good - does it 'turn' - , except for feeling notchy?

It does not bind up or anything, but I can "feel" the gears meshing if that makes any sense. My shucmaher ones always felt smoother than a ball diff. I have 5k oil in it if that matters

I did my first shakedown run yesterday with my Bmax2 V3. It was an indoor wet clay track, high traction. I ran box stock setup except for 1.6 f/r pistons, 35/30wt oil and a ball diff. The car was incredibly easy to drive and put where I wanted on the track. It was also very strong, I had some wrecks with no damage that would have destroyed the front end of the VBC firebolt I just sold!

Awesome, the car will get better with more runs.

Too much oil will make the gear different feel like that.

When I met Naoto at EOS last October, on inspection of his car the diff felt quite tight, tighter than mine did with 3K oil. I asked him about it and he said it was 3k oil, but completely full of oil, no air.

So with all the shiny new YZ-2 around now, what would you think of a YZ-2 style gearbox that fits our loved B-Max 2 chassis? Could this actually work and give us some of the YZ-2 high grip corner speed for just the cost of a gearbox and a motor plate?

The screenshot shows a very early stage of a version with an 80T spur... The lipo would fit in the maximum front position of the MR chassis. And the motor movement would allow for pinions up to 30T.

I think it is worth a try... Opinions?

Cheers
Frank

Just buy a YZ-2 if you want the features of that car.
The design of the car is more than just the laid down transmission.
Steering geometry and Ackerman is an example of radical changes from the bmax2
