This industry-first program suddenly makes learning to foil as easy as 1, 2, 3. Foiling Flight School is a simple do-it-yourself learning tool consisting of three separate masts of incremental lengths- 15 (38cm), 24 (61cm) and 30 (76cm). Choose individual sizes or as a package. Foiling Flight School is designed to work exclusively with our complete Hover Glide foil, which comes stock with a 35.5 (90cm) mast.
