FWIW: Strip ailerons should be used only on light ,slow flying models.
Structurally the versions typically sold over 50 years ,in kits were one piece of questionaable quality wood with no real resistance to twist.
Under load (speed) - twist or flutter is easy to induce
The old style bent wire hookuppoints for one servo use - is yet another issue.
I built n sold hundreds of kits with this setup in the 1970's and thru the 1990's
They were easy to do and in most cases - worked well -EXCEPT when made thin or with flexible wood and linkages -
All in all - two small servos on two shorter , wider ailerons is a much better choice.
The aerodynamics - ? the response and trimmin on two servos (today's servos ) is easy to do and flutter chance is greatly reduced.
