RE: Jeti 77 Advance Pro Opto vs Castle ICE 80 HV.
Having switched between the two a few times myself I noticed that I had to adjust my thottle curve considerably. The Castle produces the same amount of power, but in the mid range you have to adjust the curve to achieve the same feel as the Jeti. My Jeti set up is almost linear. Castle, is not... Stick at half is about 70% throttle.
