The
Merlin F3F is a very cost-effective way of getting into F5F slope racing and fast slope soaring generally. The build is very strong and the finish is first class. The model has a reputation of being groovy and easy to fly depite its fast pedigree.
The model comes with pushrod inners and outers pre-fitted to the fuselage, and an accessory pack containing linkage hardware. Also included is a nice 20 mm ballast tube to allow the model to be ballasted for very strong conditions.
