IMAC UK are the BMFA specialist body for scale aerobatics, their main aim is to promote the competition flying, in several different classes, of scale model aerobatic aircraft in sequences  of aerobatic manoeuvres as flown by their full size counterparts. The aircraft must be scale but can be of any size (Basic class models must be under 70" span) and can use either electric or I.C. power. The above mentioned classes vary in their degree of difficulty newcomers starting at an easy level (Basic)  and progressing by results attained on to the higher classes ( Sportsman's Intermediate Advanced and Unlimited)
