Why use a trim tab at all? Consider a Mac servo
controlled, spring-biased, aileron trim system. Such systems are utilized in
Bonanzas, Cozys, the Cirrus SR20 and others.
I have the hinge section, servo controlled aileron trim.
Although it works well, I hardly ever use it. If I were doing it over again,
I'd follow Scott's recomendation and use a small spring
system.
