Oops.
Spot the mistakes made today...
Found that the 450 with 10inch props can't fly / skim the ground like the 330 can! Scared me to death as I took the ends off 2 props - obviously as it was so close to the ground, no other damage.
330 - just got a bit all over the place as i'm trying to fly more aggressively. It took a beating before finally a barrel roll killed an arm.
Also - flew for a while on 1.6++ which is hairy at full tilt, sideways sweeping across the ground with the quad at around 60 or 70 degrees sideways.
Flying these things on a Naza, or even a KK2 with 'soft' settings and self level on is quite easy. Flying 'properly' is a whole different beast. I think that after today, it's going to take some time to master this....
