hi,

It looks like I carved too much out of my trailing edge (TE). which is going to have to stay attached to the wing. Will I be able to build it back up to match my wing shape with filler plus micro-balloons, or would I be better off sanding down as much as possible to hide the mistake?

Thanks,

Paul

Paul:

Micro balloons would work, mixed with white glue easy to use and shape after hardening. But weak - easily dented. NHP "Micro-Fill."

Micro balloons would work, mixed with epoxy easy to use but a bear to shape after hardening. Strong, highly damage resistant. Sig "Epoxolite."

Or you could cut a notch and fit a small block of balsa.

Whole thing edepends on how big a mistake you made.

But do avoid a rounded corner at the aileron hinge line, it can aggravate a tendency to flutter.

HTH.

Hi,

Before I read your response I went ahead and carved/sanded the TE. I hope it works out, but noted your concern about the fluttering.

The shape of the TE looks like this rather than a rounded shape:
