I'm simply one that believes that many people try to extract too much out of a 50cc plane. It's still of a size where, IMO, redundancy is not necessary if attention is paid to the quality of the products used and basic care in assembly. Then some load even more stuff into a plane in the name of safety, taking weight farther over the top. I know people load a smoke sysem into smaller planes and they fly, but they don't fly as well as they could. Typically after adding all the options there comes a series of public complaints about why an over loaded plane does not perform up to expectations.

I'm not stating that you are one of these but everytime I see pictures of a 50cc plane like ths I'm absolutely certain that someone else will be taking notes in order to do the same thing. As long as it suits you and makes you happy, what the heck.

Back to wing rock for a moment. A lot of factors affect wing rock. C/G, relative tail location, angle of attack, airspeed, propeller type, and the operator. When I did the first one I did not have a wing rock problem, but I also did not have the option of a two location wing group. I did use a prop that provided a tremendous amount of surface airflow at low speeds where most of the people out there do not. I sacrificed rpm for thrust where most people shoot for rpm over thrust.
