Hi Dave !

Wayne's got it ! You can add the extra fin if you want - all it
adds is weight .... and it does make turns a bit more difficult ...
though not significantly.

Some folks think it looks better - I prefer it without...
In test flying on floats, the dorsal fin was removed, because it
wasn't necessary, and seemed a bit of a hinderance ...
The Rebel has lots of longitudinal stability .... might help
on the Elite though ...

How much clearance should I allow between the bottom of the fin and the
top of the fuselage? Figure 12.4.4 in my manual implies that the fin is
not flush to the fuselage but there are no dimensions given. On the
subject of fins, is the extended fin recommended for extra stability when
on floats? I see pictures of some with and some without.
