Orion RS Pro Problem

[B0tt0mline]

Hi,

I am using an Orion R10 Pro (2-3s) together with a Hacker 4 Pol motor in my Durango 4WD SC (software version 1.71).

I tried the 4pol Firmware and the stock one. With the stock firmware i can go much faster...
But the reverse does not work with both firmware versions...
And the car just does not roll very long, it is like if I use a dragbrake (but it is set to 0!)

Please help me
