I find it very frustrating that no one from Viper is acknowledging this. Most of the new crop of brushless controllers has the option to change motor rotation due to all of the new platforms that the controllers are used in. if the VTX line doesnt have the option, let us know. If the option may end up on the next firmware update, then again, let us know. Or, if there is in fact a way to change the rotation in the ESC, then tell us please.
I love the speed control, but the fact that I am unable to use some of the tuning options that my car has because I cannot reverse my motor rotation is a little annoying. Oh well, I will rebuild the transmission to a 3 gear so I don't have to mess with it I guess.
As of this moment, there is no setting to reverse rotation, but nobody has really requested it either.
That being said, I am talking to Viper at the moment to see if there is a way to do it. Switching wires on a sensored ESC will do nothing but burn up equipment.
There are two problems when doing this.
(1) - The default mechanical timing in the motor is 30 degrees. Reverse the motor, you will have 30 degrees of negative timing when reversed
(2) - In the reality of how the mechanics work, irregardless of how it is configured (rear or mid motor), you want the pinion gear to be "pulling down" on the spur gear. If all you do is reverse the transmission in the car, without adding a 4th gear, and just reversing the motor, you will now have the pinion gear "pulling up" on the spur, which will greatly reduce your traction.
Mid-Motor cars have been around a long time before the 22 came out. We used to build 1st generation RC10's into mid-motor cars for dirt oval racing. In mod class you could just swap it, reverse the motor and off you went. But you had a car with allot of steering and no rear traction.
We eventually figured a way to install the motor plate on the other side of the transmission and ran the motor in regular rotation. You had a "Mid-Motor" car, the motor was in the same spot, but you had ALLOT more grip.
It is the very reason that a 2wd Buggy has a 3 gear transmission. 2 gear transmissions were tested and tried over and over back in the day. They failed because they required rotating the motor, which in turn made the pinion gear "pull up" the spur. They made the cars very loose.
The DEX210 is a really cool design with allot of potential. The concept of having 4 motor layouts is innovative, but redundant. You really have a car that has 2 useable configurations, and 2 un-usable configurations.
