This change in rotation cause throttling up in the air to drop the nose of the buggy vs. braking? Seems like I remember something about that with the early xfactory cars when they used 3 gear transmissions.

+1 it wont be that much less rotating mass. they should have reused their current topshaft.

I don't think it will have a big effect on it. The biggest factor of attitude adjustment in the air is the rotating mass of the tires.

It does have a big affect on it. Braking in the air with the motor spinning the opposite direction really limits how well you can drop the nose in the air. Hated it when I ran my durango that way.

motor rotation on an mm3 is the same as the motor rotation on an rm3, so you'll be able to jump just as well with it as with your old b4.

my dingo mm3 jumps perfectly fine. I can get the nose to do whatever it needs to in the air.

Ah yes, I forgot that the motor plate was moved to the same side as the normal 3 gear trans would be.

Maybe overthinking it. The only difference I can see with the 3 gear is the pinion is driving the spur from the front of it rather than the back of it which does not change the rotation from clockwise to counter clockwise. Guys correct me if Im wrong. I would think you would always want the rotation driving down which engages traction in its simplest terms.
If I recall correctly the 4g mid still drives the rotation down not up.

no, a 4 gear trans spins in the opposite direction of the tires and a 3 gear spins same direction of the tires

There is no such thing as "down or up" when you're talking about a motor that is spinning it's shaft in a circle.

There's a lot of things you can do for a low grip set up as Wildcat said get the brass 20 gram c block run the shorty pack all the way back, put the rear shocks all the way in on the tower, run a green rear spring, lighter oils, if you get the brass or aluminum c block you can run 3.5 degrees of toe and then put the .5 degree inserts in your hubs to get 4 degrees of total toe, and run the b5r rear arms and push the hubs all the way forward those are just a few things you can do to get more grip for a low grip track and it should have just as much grip as a rear motor car!

I am on my third week of running my B5M with a 17.5 setup, at an indoor medium length track that starts out tacky, and after 80+ entries and 6 hours, starts to develop a layer of dust, even when the track is blown off between rounds.After the first week I thought... crap, i ordered the wrong configuration, this Mid motor sucks. On throttle out of the corner, I couldn't keep the rear wheels under me for the life of it.

I also looked at the brass pieces and thought "well thats dumb, because if the track is tacky to start, you have to pull everything apart to switch hangers back and forth as the track changes" I actually put the 30* block in front to assist in steering, and drilled and tapped the rear shock tower for a 4mm screw, and made a block of weight to add as the night wore on and the track went away. Car stuck like glue, no more feathering throttle and ddrs punch is back at 90%. night and day difference. The only other thing i did to make it work, was i also ran Sticky Kicks Red. Traction is no longer an issue.
