I have loaded the last version using the USB interface. This is great! I can use Hitec BLS servo (340Nm) on the elevator up to 15ms with a very clean and smooth movement. I still have some jerky movement on the rudder (Graupner HBS860) under 21ms but it is very acceptable. I will use 18ms for all servo.
So now the Aircraft can fly without problem with 2 Graupner GR32.
Thank you for your great support and the quality of your products!
