During the build of my 235 (back in the days when the builder's maunal was 
mostly hand-written and the illustrations were mostly hand-sketches) the 
requirement for thick, squared-off trailing edges was applied only to the 
ailerons. The reason given was that sharp trailing edges exhibited a slight 
dead-band so that the stick had to be moved a bit before there was a 
response. Since I followed the advice and made my aileron trailing edges 
about 1/4 inch thick long before first flight, I have no idea whether I 
would have had the dead-band or not - suffice it to say, there is absolutely 
no dead-band in my roll control. All other trailing edges, flaps, rudder and 
elevator were not constructed in this manner - they are relatively sharp 
(maybe 1/32 in.) consistent with what I considered was required to make a 
strong skin to skin bond.

Further, during my test flying phase, I carefully worked my way to about Vne 
+ 10% searching for any hint of flutter onset and found none.
