I can set the PRO for constant RPM, but I did not find setting for slow acceleration and then quick reaction during flight, that is what I must make clear with Jeti guys. Either I was wrong and they will tell me how, or I will try to make some modiffications to firmware, and of not, I will at least try to convince them to make us "non pro" version. We will see.
And yes you can have timer, I sale them for 100Euro. It is prorammable with Jetibox, you have it I expect.
