Does adding a 1/2" to the trailing edge of the aileron effect flying characteristics of the aircraft? I am building an older 33% scale 230 Extra kit from ACE . The kit says to cut off 1/2" of the foam the entire length of the trailing edge including aileron. I wanted to leave as is, because it already has a perfectly cut edge and I can glue the 1/2" x 3/4" Balsa trailing edge to it instead of cutting then gluing. This would add an additional 1/2" to the aileron.
Is this a good idea or should I follow the kit recommendations?

Thanks
Any Info would be greatly appreciated
