Maybe...it does hit the turs a little Bette, IMO. The MM cars are limited to high bite, astro turf, and carpet. Indoor tracks are not very popular in my area. RM motor will be here to stay and continue to be the most popular, IMO. Look at the post and view count for each.

Mid motor is here to stay. It definitely works better when traction is really good but its pretty incredible how fast a mid motor car can turn period. There are 2 reasons why people try mid motor, don't like it, and then switch back right away. Set up and driving style. You have to be patient. Set up is a little harder. Once your car is set up properly you have adapt your driving style accordingly and for some that's harder than setting up the car. All you need to do is drive a real mid-motored car....you'll feel it right away.

PDF of all lap times.

Ragarding the A-main, First, Second, Fifth, and Sixth were all running mid-motor. On a med-low traction, tight indoor course.

Also, I really think AE is getting it right. I preordered a RM B5 and it was cheap! I'm a total Kyosho fanboy and in terms of RC I can afford whatever I want and I'm here to tell you I'm tired of paying nearly $500 a roller. F that. Kyosho stuff is better quality, no doubt but after Tower coupon the B5 was a hair over $200! I could by 2, paint, and tires and I'd still be spending less than on a K-Car roller! Last, the B4.2 is still competitive. The B5 should be better.

Pros run to win.And as we've seen even if that means not having a production made car.
But what most people are not realizing is you need to drive most mm cars different than you do a RM. I know a lot of people have driven RM for many many years and it is like learning to drive all over again for me when I went mm but has been a fun and really rewarding process learning something new.The new and having to learn a new way is tough for a lot of people and makes them have a bad taste. It is hard to teach an old dog new tricks but can be rewarding.
If you go mm be patient learn the car and driving style.running 3 packs or even one week with a new kind of car isn't necessarily going to be long enough. Some pick it up quick some others like me it takes alittle longer.
Thank you. I am thinking I will get the mid motor and then I will have both a mid and a rear buggy. My son and I can take turns driving each so that we can experience the different driving styles.

I agree with your plan--and I think you'll be happy that you went that route!

I read a bit earlier that the TLR guys made a determination that the force exerted by the diff rings on 14 balls was more detrimental than the force exerted on 12. They stated that the 14 ball diff actually had a smaller tuning window than the 12 therefore requiring constant tuning to keep the diff where they wanted it. So to summarize they felt that the 12 ball diff stays "in tune" better than the 14. Basic common sense would lead one to believe that the 14 ball concept would last longer however--and maybe that's why the appeal to the mass public??

The ball diff in the DEX210 uses 3mm balls, and uses 14 of them. It's the single best diff I have ever run (too bad about the rest of the car), and it's "tuning window" didn't feel any different. Actually.. i think it might of been slightly more forgiving. Im excited to hear that AE went with a 14 ball diff. I assume it will be 2.4mm ?

For example, here is a race at my local track recently... All mid-motor cars you will see. But we have probably 10x the traction. If you put the surface from your track, with our layout... mid motor cars wouldnt' be able to make it around the track. RM would dominate.

A lot of 22 people are buying the XXX diff gear so they can run only 12 balls. Doesn't mean 14 won't be good-erer on the B5 but the TLR diffs definately have some problems.

Reedy race will be interesting to see who is running RM and MM if 2wd for all manufacturers.

Well, I would guess the AE team will be running the b5...I dunno if they have production run RM or MM cars though. But it would be a good race to show off the new car. Hopefully, cav and maifield get some solid wheel time before the reedy if they have b5's
