Rapier Model Hydrofoil


This the design and build of this model was featured in Marine Modelling Monthly magazine, December 1992 issue, by Traplet Publications UK, pages 36 - 41.  Plans for this model are still available from Traplet Publications.
Unfortunately since publication the 'half-round' aluminium strip (sold in hardware shops for edging worktops and the like) used for the foils may now be difficult to find.  Modellers may try metal strip, such as a 3 foot/1 metre ruler.

For construction notes to accompany the plans see below::

Note all the foils are detachable and fixed using 'breakaway' nylon bolts to protect the hull in case of crash - yes this works!
