With all respect boys!
I gave up the Ice 80 with the himax 210 ( falcon 20,5x14,5 + 21x14 also Apc 21x14) when I took it over I think it was 37 % brake it was  screaming when I got from brake to higher throtel, I tried diffrent settings some that I found here and tried to change it from that ..no luck.
Have now about 15 flights with the Futaba/Os and seems to work nice!
when I got down from the fig9 in P13 it sound like the plane was getting any damage!
so with the Himax no more Castel maybe I can try it with another motor but at this point I dont see any reason to play with it
