Frequently asked questions
Which length should I choose?+
A short mast is easier for learning and for shallow water; a long one gives more margin in waves and chop. The 82 cm is the most versatile.
Which fuselages does it fit?+
Aero AL 3BS fuselages, D/LAB wings with tail and Duotone and Fanatic carbon fuselages.
SLS or AL?+
The carbon SLS is lighter and stiffer; the aluminium AL is more affordable and very direct.
