let's say it like this.....my trainer i started with 80/100 after i got used to that i increased to 100/120 (or 140 i can't remember which- it's the highest setting on the 6exa) the plane flew nothing like the slow lazy trainer that i remembered. i literally outflew the airframe and after a wing failure (just gave way at the wing joint during straight level flight) and a repair, i haven't put any electronics back into it to try it out.
