The Learning Curve...
 
Gents, gots a question for y'all on 3D set up. I know this question might be impossible to answer, but I'm gonna let er rip anyway. Anyone have a formula for the perfect 3D set up? I have an AW Extra 260 75cc with a DA-85 just to set the stage. Power isn't an issue, that motor tugs! I'm guessing I'm missing something with CG or deflection or I'm just really crappy at this... She's a great flyer and pretty light on the wing, but kind of wild in the hover. Wing loading is about 29 oz psf. Decent rolling harriers, but kind of all over the place. Any flight tests I can put her through? Or any other thoughts?

well CG personal pref ..

what i would do is a basic trim set up so like many others you can use mixes . first CG trim I'd set up my plane to flight a inverted flat line with natural trim other words hand's off vary little decent or Clim

second airlon diff up line with the least amount of wind affect possible doing Axel roll to the right and to the left you'll find out mid wing's don't use alot of differential

make sure to check your thrust angel with a vertical line also . check your rudder with a power off straight down line again least amount of wind affect possible

knife edge mixing use the P mix in your radio start out with a small ratio and just keep flying knife edge passes from right to left .. left to right and add percentages via mixing in elevator to rudder to get a hand's off knife edge for a exmaple i have 4 precent elv to rudder on my p mix .. some time you might need to add airlon into the mix if you have alot of toqure affect


but after going thought all the mixes all the set up . then you have to get your mind use to the model stick time


edit roller's aren't easy if you are off you should maybe look up some of josh's clinics and spin more time in inverted harrier and up right harrier figure 8's

also try use differnt rat's or servo speeds if you get a crazy fast servro with a giant airlon , it's not going to be vary easy to stay on top of the transition even with pilot's that can do roller's on there own plane they can't just jump into someone else's plane set up different and go right to a smoth roller the timing is going to be a issue.. ( atleast most the truely talented and blessed one's have the speed and smothness to do it )

The above is all good
You may want to post your actual deflections, servos used, battery, expo used on all controls and prop, helps other visualize the plane and gear alot more.
Expo can be critical and a deciding factor for much of the flight envelope.

just my peronal pref i really do like ' josh's clincs " bonedoc is a great flyer and he's vary good at explaining thing's plus with his vedio's of the sticks it help's put the montion's into your head


try to look up his POP TOP vedio :D it's lots of fun with gaint scale

Too cool! Thanks guys, I got me some flight tests to do! Any other input would be greatly appreciated! BTW Bone Doc is the man! I wonder if he's adopting???....

Every plane is different, and every pilot is different, it is not something you can have a formula for, except for something like 1) first get your c of G correct, 2) get your throws correct 3) ...........
Practise, practise and be brave is my formula http://www.youtube.com/watch?v=GTtxStJJyFI
