[MT-ALES] NATS Update

[Duane Beck]

F3L is two-meter wingspan limited to rudder, elevator, and spoiler
controls, but there are further airframe construction limitations than the
traditional AMA RES class. Fuselage forward of the wing trailing edge, and
all flying surfaces must be constructed without composite or molded
components, except for spars. Like F3J, the fuselage cannot have any
protrusions on the bottom, other than the tow hook (e.g. no skegs and no
rudder or fin below the tailboom). Also, the high starts are limited to a
maximum of 4kg (8.8lb) pull at 3× extension, which means the airframes tend
to be quite a bit lighter than typical for AMA RES, which is most often
launched by electric winch.

I was going to include a link to the FAI Sporting Code rulebook, but the
website isn't loading for me at the moment.

Hope that helps.
