Thanks for the response Vaughn. I would love to hear
what would happen if someone showed up at the glider
port with a set of scales and weighed one of these
SparrowHawks as it sits. I guess I wouldn't be surprised
if 85% or more of them were over the 155 pound ultralight
limit.

I guess that if you are under the 155 pound limit,
then you can continue the argument of to tow or not
to tow an ultralight. But if you are exceeding the
155 pound limit, then you are no longer considered
an ultralight and need to step up to the plate and
get an N number. Then, there would not be a big discussion
over the legality of towing.....

Now I have another question. If you are flying a Sparrowhawk
and are trying to break an ultralight record (not sure
if someone is going to come up with another record
category like the World Class) are you going to have
to weigh your ultralight before and after the flight
to verify that you are truly an ultralight?
