Rear motor? I didn't know the car could run the motor on the rear of the car. It is a specific mid motor car. Rear motor would need different suspension geometry. As for buyers remorse. Xb2 is again hands down one of the best buys out. Go run the car and be happy with one of the best cars out.

When you read about it having the motor having a mid or rear configuration, its not what you think. It is a dedicated mid motor buggy, but you have a choice of setting up the motor for mid or mid-rear as they call it. one way has the motor sitting further back by 12 mm i think. But it is still in the mid motor configuration. One is for med to med-high traction and the other is for low to med traction. Then the carpet edition is for high traction situations

No one runs rear motor anymore, and with the stock setup on the dirt car, I doubt you need it, it has so much bite.
If you bought the carpet car, then you've really made a mistake.

Why yes it is very easy to get! Not as easy to actually get a rear motor car. And it is so much cheaper than a xb2! Thanks for the picture! I am amazed! Why not go backwards with engineering? Can't wait to run my rear motor car and take another hit off that stuff! I bet their are more people than you know that smokes that stuff!

Schelle slipper
So I've tried the b5m top shaft swap. Tried shimming for the odd size 5x13x5. I used a 5x13x4 with a1mm shim. Also had at least .75mm of play on Inside of tranny also shimmed that. I could not get the top shaft to rotate freely. With the slipper on and barely tight it had a bind to it. I believe in order to do this the odd ball bearing 5x13x5 will be needed.

Legalities huh? Care to point to the US patent number that would prompt legal issues? Because through my searching, I can't find a single us patent that speaks directly on motor placement in a RC car.

thats all i was told.. there was an issue with gearbox design..
"Rear motor is coming.
Originally it was going to be one gearbox for 4 gear laydown and one for 3/4 mid and rear, but due to a (car brand) patent they can't make it like first intended."

Probably Durango's patent
From: http://www.team-durango.com/race-cars/dex210/
The DEX210 is unique. That is why the gearbox design, our 'Hybrid technology,' has a pending patent (GB1112236.3). The DEX210 allows you, the racer, to choose if you want the motor to be in rear- or mid-motor position. Not only that, you can choose whether you want the motor to be on the left- or right-hand side of the car. All of these configuration options are available with the same gearbox unit and without altering the suspension geometry. This ability, to tune the weight distribution and torque orientation of the motor, without changing your suspension set-up, is what makes the DEX210 unique. The DEX210 is arguably the most tuneable yet user-friendly pro electric off road kit available today.

Hoping it will be ok in my track since its pretty loose and no one uses mid motors.

someone asked posts back why i used the brass nose piece, it was for steering and not for jumps. for 17.5 was maybe not the right choice...weight wise
i ran the DE stock set-up with 29deg brass and 0deg insert in C-hub on a actual dirt track (only watered) Weds. the car had killer steering with no effect on rear end. the imo was good on single, double jumps, it went where i pointed it and had a onroad (which i'm used to) feel thru the course. i really liked the car.
however...the course has a quad section, and a jump to table top with a quick following triple. this is where.....I and the car failed really bad. at this track if you can't one shot the quad, and 2 step the other, u will be left behind. this part was severely aggravating
several factors play here?
- me
- car was too heavy w/brass nose (landed short)
- running a older 17.5 and old lipos (worked in previous car fine)
- charging at 6 amps (max on my charger)
- car was too soft
- was trying to figure pinion gearing for 75 spur.
- was also running a 1/8 scale e buggy, which made me marshal the heat right before 17.5, and robbed time thru the night that imo should have been on my DE.
for tomorrow i made changes to try:
Socket's 35w F, 32.5w R, 1 deg AS, 3 deg R-toe changes. on springs i will try xray 2 dot F/R. i removed the brass nose, went to stock, but going to stay with 0 deg insert in C-hub for steering.
the 1/8 buggy broke in it's 2nd place finish, so it will stay home awaiting a horizon order.

i think Durango's patent has to to do more with the unique 4-gear box design allows a rear motor placement that is farther forward than other rear motor designs the DEX was made to compete against TLR22 2.0, B4, B5, etc
motor placement in regards to it's position imo such as rear, cannot not be patented.
if xray added a rear motor guard, and a way to reverse mount their 3-gear box, imo this would not be a issue concerning patents
