RE: Giant Telemaster Build
Hi Don 41,
In Australia models weighing 7 Kg or more (without fuel ) which is about 15.5 lbs, have to be inspected and given a "heavy model" certificate before they can fly. This is mainly for insurance purposes. The inspection is done by a trained heavy model inspector . Not only does the model have to pass this process but the owner /pilot has to be certified as being capable of handling the model even down to the sort of flight manoeuvres that he/she can perform. This is done by flight testing with the inspector observing the process. This certification which only applies to the individual model ( in other words if you own a number of heavy models each one has to be certified ) has to be renewed every 3 years. To a large degree this process all but eliminates oversights like your aileron linkage keepers. As I'm sure is the case in your part of the world, big and complex models are now very common so this process is also very common.
Regards,
Tim
