We have developed an assortment of components to assist you in building your own designs or conventional multi-rotor craft. Our Motor Arm Lugs can be adjusted in 15 degree increments giving an unique ability to the designer to test different motor arm angles. A great tool for the education process of design thru construction. I have also found that this construction type is extremely stable, a nice surprise. Body sizes can now be designed to match the requirements of what the multi-rotor will be required to do or carry. We hope to have QuadLugs unleash creative minds to move multi-rotors to the next level and truly give a new multi-rotor experience. We are anxious to see the designs to come, please share with us your creations. Visit us at quadlugs.com for some of my designs and more info.
