I try to take detailed notes when I build a plane. Weight, engine, initial settings, prop, fuel, all parts (servos, receiver, battery, etc.) CG, and then I try to list, objectively, my honest opinion of what I liked and disliked about the plane. Then I can go back when I fly it next and review the notes and decide what to do, if anything, to improve the airplane. I use the flight sheet on the back of Great Planes manuals. I also try to record flights with each plane. How many, conditions, improvements, damage, opinions, etc. This way I find I have facts rather than conjecter. Do any of you do the same. Please share improvements, how you do this, etc.
Thanks,
Barry
