The original wingmount in 2011 had a weakspot where it could break. It wasn’t a big problem, so we made a running change, and it has never broken since! No one even noticed :-) . We have released optional CNC high wingmounts, (JQB0197, JQB0198 (Black) JQB0204, JQB0205 (Gold)), these raise the wing up higher, increasing stability specially at high speeds and while jumping. Definitely worth getting!
