I like the whole concept
of helicopter recovery so couldn't resist trying this one out. The
instructions can be a bit tricky, but it goes together fairly easily.
It appears to be a very "draggy" system and also requires a lot of clay
in the nose to make it stable. Package says the weight is 2.5 oz,
but mine was more like 4 oz. Lots of plastic in this one.
Launch: First through 3rd launches occured all on the same windless
day. I strongly recommend only C engines in this puppy. First
flight on a B6-4 was too close for comfort. Subsequent flights on
C5-3's were acceptable. There is one major problem I haven't been
able to overcome. On every flight, at least one of the rotor blades
would pop off and float down on its own. The rocket recovers in a
semi-helicopter mode but is not damaged. The whole system for attaching
the blades to the rocket is questionable so I will have to figure out some
way to make them stay where they are supposed to.
