Pro drivers are paid to push a product. Its the flavor of the week. I mean if you really examine this closely youll see unless you drive at a track where team drivers run at the MM car wont work the way its designed to. I mean dont get me wrong it looks cool but. How many high grip outside race tracks are there. Just my opinion.

Cav does not race outdoor blownout tracks. That being said, I race on outdoor track and I got my doors blown off by a guy running a MM 22 last weekend. He is the only mm at the track and his car was fast in the corners and seemed planted. He was by no means a local fast guy, but his car looked so good, that I am looking to try out MM once the b5m is out.

You said it pro drivers run on indoor high grip tracks. MM might work for a few people outside but its a high grip car. Theres no debate.

I have never run mm, so I cant really debate it. I just said the this local went MM a few weeks ago and is flying with it. Soooo much corner speed. That being said, the local TLR drivers run RM outdoors, so yeah.

You might want to check out the B44 thread and just ask questions..plenty of club guys with tons of laps that can tell you all about it.
I agree the TLR forum support is the best in the business but do note that you have had two different AE design engineers answer questions about the cars on this thread and that seems perfectly adequate to me at this early stage.

I think manufacturers have to walk a fine line because because when you hear about all of the tinkering the pro drivers and engineers are doing with their cars to up the performance it can be perceived as addressing weaknesses in the car, rightly or wrongly.

So being that I am one of those "on the fence" people, do you think I would be happy with the B5M? I currently race B4s and will be keeping one of them for my son. I generally race on medium bite tracks, but occasionally I run on a lower traction dusty track. I just can't decide between mid and rear.

seems like the west guys are running more mid and the east guys run rear for the most part.

I started the 'push brake' method a while a couple of seasons ago. It's not entirely different than using brake on an 8th scale(The vehicle dynamics are different though).

A combination of ESC brake strength, brake exp. and brake endpoint makes the entry braking smooth. This combination makes it difficult to spin the car on entry(unless you grab full brake). The advantage to this method is that you can set your car up a little "tighter" to have more forward bite.

My motors make a slight whining sound when I grab the brake and it makes guy's at the track think something wrong with my car. lol

Meanwhile on the other side of town(), I able to get in and out of the corners before they've hit mid corner.

I think there is more mid to high grip 1/10 racing happening at this point and loose dirt is not attracting 1/10 electric as much. These looser tracks are doing 1/8 and SC racing at this point because they're so much easier to drive in those conditions. 1/10 buggies used to sell significant numbers to bashers (still can't believe we use that word..) but now there are more and better choices for that use.

Mid will develop much faster now that pros and companies are committed to it. I predict TLR re-does their gearbox in the near future to keep up.

Re: the push-brake discussion. I found that gluing a piece of silicone fuel tubing to the back of my brake trigger to make the spring stiffer in that direction helped a lot with feeling the trigger travel since it's so short and that side of the finger is so much less sensitive.

I am thinking this mid motor thing is going to be a fad. I fell for it too.

TLR just went through this with the 22. I recall there being lots of problems and many went to the 12 ball gear. Hard to tell how much the extra 2 diff balls contributed. I am of the opinion that the majority of their problems were caused by the choice to save $$ and spec cheap chrome-steel balls (I also think they believed 14 balls would let them get away with this) and a flood of newer racers coming from SCT racing without several years of experience with ball diff's.

The physics are undeniable. Before long it will be a near-standart at most indoor tracks. Mid motor is here to stay, even if it doesn't make rear motor go extinct.

I also know through experience with the X-Factory that they redesigned the rear arm geometry to better assist with rear traction.
So to summarize I think the cvd-bind, the rear arm geometry and the 4 gear tranny all benefit the dedicated MM design.
What intrigues me about the B5M is they went to the gull-wing front arms. They stated that these arms worked great on the mid while the rear benefitted more utizlizing straight arms. Am very interested to experience this--sounds like yet another evolution in these awesome mid-motor designs!!
As a side note--people shouldn't criticize any company that offers dedicated RM or MM designs. For the SERIOUS racer this is the only way to go.
I still think the biggest advantage to a dedicated mm chassis is getting the weight in the right spot with the battery placement. Inline batteries on the mm conversion cars get the rear weight to about 62% max, while a side by side saddle arrangement can get the weight up to 65%+ on the rear, which is close to what a RM is with the battery all the way forward. I struggled for a while with my mm dex to get it to hook up before I chopped up a chassis to get the weight in the right spot. Instant difference. That's when I learned weight distribution is key.

I think people will be surprised when they try the b5m on surfaces they wouldn't normally think to run MM, especially if they tried a convertible car before.

You can get away with the mid-motor on less than ideal track conditions it just takes some tuning on the car and also tunning of the brain. A lot of people keep saying mm is only good for this or that and the pros are only going to run this to promote it. Their wrong. 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.
