Default mid motor shootout

In a shoot out between mid motor cars on a dirt track, I think you will find the following:

3) losi 22 has the distinction of having the least amount of steering, and the least rear grip (a neat trick) because the motor is too far forward and the car doesn't generate a lot of natural steering

2) the rb6 is better and smoother, but because it is a convertible car, you don't have the weight placement options (battery is down the middle, which means more weight on the front end, which can mean less rear grip)

1) b5m has all of the options needed to tune a mid motor car correctly including weight across the chassis and a motor close to the rear axle.

In addition, the b5m is $259, the 22 is $329, and the rb6 is $449, which is quite a difference. Especially between the 2 better cars. Once you add some tuning options to the rb6, you can buy 2 b5m's.

At our track, many tried and gave up on the 22 mid motor (1 driver is left.) Most of the fast guys had either the c4.2 or the rb6. All of the fast c4.2 drivers have moved onto the b5m. We will see what will happen in the next month or so as the b5m is tuned, but it is already proving more consistent than the c4.2, along with being more durable and tunable.

Your mileage may vary.

Does it matter if the ESC placement is on the opposite or same side as the motor in terms of weight distribution?

What about the DEX210 Midmotor

Interesting insight on all 3, I will keep this in mind while testing, Thank you for the comments. Testing will be done on an indoor clay, med bite track. I have ran the RB6 and 22 2.0 back to back for several weeks and I have found some differences between your comments. For the record these are only my opinions.....we all have one and we all have different driving styles and preferences.

2) the rb6 is better and smoother, but because it is a convertible car, you don't have the weight placement options (battery is down the middle, which means more weight on the front end, which can mean less rear grip)Both the RB6 and 2.0 are convertible cars, I am a bit confused by this comment. Both cars also have the battery down the middle and the RB6 can be altered to put the battery sideways. Better and smoother are a matter of opinion. Personally I feel both cars have very good/smooth suspension, but the RB6 seems a bit more "flickable" to me.....sorry I might have just made up a word

1) b5m has all of the options needed to tune a mid motor car correctly including weight across the chassis and a motor close to the rear axle. The motor appears to be closer to the rear axle compared to the other 2 when looking at all 3 of them side by side. I would also agree it is a "pure" mid motor car in the sense that it can only be configured this way and was engineered to do so.

In addition, the b5m is $259, the 22 is $329, and the rb6 is $449, which is quite a difference. Especially between the 2 better cars. Once you add some tuning options to the rb6, you can buy 2 b5m's. Agree on the price point in regards to the RB6!! I am sure we will all do some upgrades (once available) to the B5M that will add to the bottom line....that is half the fun isn't it . I don't have much of a budget for RC, hence the "shootout". It will simply come down to what I prefer based on my ability and driving preference, as you state, mileage will vary

At our track, many tried and gave up on the 22 mid motor (1 driver is left.) Most of the fast guys had either the c4.2 or the rb6. All of the fast c4.2 drivers have moved onto the b5m. We will see what will happen in the next month or so as the b5m is tuned, but it is already proving more consistent than the c4.2, along with being more durable and tunable.

Here are my car weights in mid motor trim, all with the same battery for comparison reasons. All 3 are 17.5 blinky cars.

22 2.0 - 1538 grams (this is with Rocket RC anit squat brass block)
RB6 - 1558 grams
B5M - 1568 grams

No pucks and I am running the Orion R10. I do have some titanium adders to help a bit though

I am curious to see if anyone comes out with a CF chassis plate for the B5M
