V-Tails Rule!

The National Film Board has done some good work. The reflections in the
pond are classic NFB.

Agreed - I always thought "180 is Max" was great -and gives a pretty
good idea of what a top level free flight competition is like despite the
low resolution of the copy on YouTube:

... but I think its a copy of a copy. IIRC the first time I saw it the
images were quite sharp, but this copy is still good enough for me to
recognise old friends.

F5J Electric RC

Pilots are penalized .5 points for each meter during launch up to 200 meters after which a 3 point per meter penalty is applied. No motor run is allowed after 30 seconds. Max flight is 10 minutes with up to 50 landing points awarded. Go over 10 minutes and you loose any landing points.

The F5j sailplanes are very high tech. Most now are molded all carbon with 4 meter spans weighting 1200-1300 grams.

Interesting - don't know anything about F5J, but have watched F5B and F5F
models flown. F5B are about the most scary models I've been close to.

F5J is interesting and, now I've found and read them, a most interesting
set of rules. Thanks for posting about it.

I am/was primarily a free flight guy. Competed at all levels in F1A (FAI
towline gliders) plus 1/2A (small power models - 0.8cc/.049 cu.in. glo
motors) and F1J (FAI small power models - 1.0cc glo motors).

The F5J idea of penalising climb heights is especially interesting,
particularly as in the F1 classes we're having problems with model
performance exceeding the space available inside flying fields and with
no acceptable ways of limiting performance suggested so far.
