I found that by adjusting the aileron linkage at the aileron you can get the plane in perfect trim without trim tabs. I dont reccomend this if you dont know what you are doing. It is always better to bring an aileron up to achieve trim, going down increases the effective angle of attack and changes the stall charactistics. You should have an AP to assist you.
