Real e motion B+ : resistance is too high

[Fefosaure11]

Hello,
i ve got this one and for me , the resstance is too high. It s very very difficult to turn my legs when the slope is over 5%.
Even when the road is flat, it s difficult
Outside, with a slope of 2 ou 3%, i can ride at 25 km/h. On the home trainer, it s nearly 15 -17 km/h and it s difficult.
Without resistance, I find it s already difficult..
Someone to help me ?
Is it a problem of calibration ?
Thanks
Excuse me for my english

I have exactly the same problem; the equivalent effort on the road or turbo generates 50% more speed than I get on these rollers. Have you resolved it?
