Hi all,
I'm putting together the wings of a Satellite 788 GLH.
Looking through the instructions, they refer to 1/8" washout of both tips and ensuring all other panels are flat.
My question for ya'll is this: With the passing of time, has there been any change in approach (e.g. washing in of the right inner panel), or is it a case of "If it ain't broke ..."?
Cheers, Dave
P.S. The noise-maker will be a Fox .36 Combat if that's of any relevance.

I would have the washout on the tips, and a little washin on the inner right hand panel, with a little down thrust and a little left thrust on the engine.
Tail tilt right hand tip high to give right hand glide.
Good luck, and let's know how you go.
Do you belong to NSWFFS?   Lots of trimming help there if you need it.

Thanks Gossie.
Am based in Vic but I think I'm a member of NSWFFS. Yet to make it to WW. Last big comp was 2019 AFFS, and that was just for one day.

The original tip washout/flat inner panel setup was for the original right/left power pattern.  This has since been proven potentially problematic and superseded by the right/right setup suggested by Gossie.

The California method is a different approach.
It uses no wash-in. It does skew the wing with the right tip forward which effectively gives wash-in under power.
It also uses right thrust -insert 'yikes' emoji here- which I assume has to do with the nightmare of ROG launches.
With the wing skewed like that you are locked into gliding left. You can get away with gliding left if the right side has no wash-in.
It also has the fin on the stab which tends to make longevity on a fast gas plane a non-issue.
