Mitch, can you tell us what the figures mean, and what the judges expect?

That's a loop, a half Cuban, a flat 270 turn, and a roll?

Mitch, here's a basic description:

Loop: Should be round, entry & exit altitudes should be the same

1/2 Cuban: First part should be round, stop on the 45° exactly, the roll will be a slow roll, should stay on the 45° before & after the roll, the line before & after the roll should be the same distance.

270° Turn: Roll into the turn on heading, turn can't start before the wings are at 60° or better, same thing on rollout, stop on heading, then roll out. No altitude gain or loss.

Roll: Technically a slow roll (that doesn't mean it has to be slow), rolling about the axis, no heading change or altitude change.

HTH

Default Tks

Thanks Doug...i was busy helping a local rv8a owner as to how to roll and not gain/loose any altitude. He was barrel rolling this thing so bad and loosing 300 to 500 feet on each roll. , we worked on his mechanics until he got it...All the kinks were worked out and now he is loosing less that 20 feet from starting attitude.. I noticed on the rv 8 as you are 60 degrees and top rudder and just before knife edge the stick needs to go to the 10:30 position otherwise you will barrel this thing nose down...transition to inverted it holds very nice attitude. We did close to 40 rolls yesterday @3500 agl and noticed best speed to be 120 kias. I like how the rv8 slow rolls too.... It looks like we have gain a few of you interesred. Come join us at an IAC competition wherever you are and inteoduce yourself! We are plane nuts just like all of you and EAA,rs!
