Hi,
I''ve been practicing taking out the wrinkles in ARF covering with a covering iron. My test subject was an old not-great quality p-51 ARF (it looks like a wrinkled dog).

I used tips/instructions from the following post by krproton:

(may need to scroll down a bit after clicking to see it)

My practice session worked out well and was on the fuse with mostly plywood sheeting behind the covering.

My question relates to de-wrinkling a horizontal and vertical stab on my new trainer ARF (my actual immediate goal). They are made of relatively thick balsa sheets.

The above link is very good and informative, but does anyone have any specific tips for de-wrinkling balsa-sheet-stabs in particular?. My concern is that I might cause the stabs to bow even a little, which would be terrible. Any tips or elaborations on the technique specifically for avoiding that?

Thanks

p.s. The tail stabs were the only wrinkled parts in my trainer ARF. Everything else is really nicely covered.
