Tuning

Building a high performance freestyle quadcopter is a complicated task, and many pilots usually settle for ‘stock tuning’ which the flight firmware comes with because the mere construction is enough of a challenge, let alone learning about gyro filtering and PID control theory…Stock tuning however is usually a low performance compromise in order to be safe and applicable across a broad range of components. Sure it flies ‘ok’ but the PIDs are usually much lower and the filtering much higher than necessary resulting in a loose and latent performing build-it is like driving a Ferrari with tyres half inflated. However knowing what to change and by how much can seem baffling and the result is often a lot of head scratching when most people would rather just fly…

One of the goals at Supafly is to help anyone get a high performance quad that flies as good as the ‘Pro’s’ you see in videos (or better 😉 ), without all the confusion. A well tuned quad feels totally ‘locked in’ which is a description of the way it feels to have the correct amount of P and I term locking the quad in place in response to stick movements. This encourages better flying because of the subtle subconscious effect of having better control. The correct amounts of D gain and filtering smooths out the flying and results in noticeably better HD video. 

All flight firmware have their pro’s and con’s, and soon there will be an updated Supafly tune for all. Any tunes published on this page can work for other similar freestyle frames, of course I cannot guarantee it…and for my customers there are some custom setups available on a password protected page.
