Re: Flap Setup

I seem to remember a long time ago that this question came up but I=27m not
sure it was ever resolved.

The offset flap cross-tube/flap actuating rod (biased towards the starboard
(right) side of centreline) seems to result in the port (left) flap not
quite reaching the fully up position - pulled down it seems by the weight
of the outrigger leg which does not have an uplock. The starboard flap is
fine.

Now I=27m not talking much - just 1/8th inch or so at the trailing edge but I
have incorporated wing fillet extensions which blends in the flaps to the
fuselage in traditional style (which it turns out is more for looks than
aerodynamic cleanliness according to some who have tufted their fuselages
to see the effect) so the slight difference in retraction is more
noticable.

Did we ever find a way of stopping the flexing/twisting (made worse no
doubt by 2 or 3g turns pulling the outrigger leg down further) or will the
landing gear bungee help to even out the balance? Its far easier to put the
flaps down than to raise them at this stage so presumably you will bias the
landing gear bungee accordingly.

Any thoughts or comments would be appreciated.

There is a partial uplock on the outriggers caused by the top of the OR4 rubbing
against the bottom of the OR6.  Incidentally it will be necessary to file a
small slot in the wing rear close out to provide clearance for the OR4 - this
is not mentioned in the earlier versions of the Builders Manual.  Don=27t file
the top of the OR4, though, or you will lose the uplock feature.
