Everyone is interested in reducing build time and building a better product. I've been able to do that with flaperons, used on our Belite ultralight aircraft. The time required to build a flaperon structure is now down to less than four hours per flaperon!
This assumes an easy to build wooden jig, which will hold all the ribs in place.
This is an update over our earlier manual, published just a few weeks ago.
These techniques may be applicable to building control surfaces (elevator, rudder, stabilizer, etc.) on your favorite ultralight aircraft.
At Belite Aircraft, here's how we do it.
