Brief:
The Scott Special One is a 4 inch rocket high power rocket, designed as dual
deployment, and is a great sport flier. There are many custom options
available.
Construction:
The kit I received was complete, nicely packaged and in great shape. There is
one 4 inch main body tube made of flexible phenolic tubing with the fins slots
cut out. The upper section and 54mm motor tube is also flexible phenolic and
the altimeter bay is a LOC unit. The centering rings are a full phenolic type
and are very nice, but they do have to be roughed up for epoxy to get a good
bite. The nose cone is a blow molded plastic type. Hardware is all stainless
and U-bolts are used--very nice! The fins are made 3/16 G10, and are cut very
well (lighter fins are also available but I went for the heavy ones). The shock
cords are tubular nylon and follow Scott's rule of use as much as will fit. The
parachute is a custom made cup style chute that has only four shroud lines and
is very, very well constructed. This is a very well thought out kit.
The instructions are well written, and easy to follow. All components assemble as designed and the fit is wonderful. Slight sanding on the centering rings is needed but this is to be expected. Anyone should be able to put this kit together and have a flawless performer. This kit would make a great level one or two kit.
I did make a few modifications from the standard, as I fiberglassed all sections with 2 wraps of 4.5 s-glass, done with Aeropoxy resin. I also put s-glass tabs on all fin joints, as well as using Kevlar® pulp for filler in my initial fillets. This made for a very strong airframe and VERY strong fin attachment. All centering rings are also put on with the Aeropoxy and Kevlar® pulp mixture, and I must say this works very well. The altimeter bay went together as designed and is very functional.
Finishing:
There are no decals included with this rocket. It is not painted yet, but I do
intended at some point to get around to painting it. Even with the extra
fiberglass and the thicker fins, it still only weighed a little more than eight
pounds without motor.
Construction Rating: 5 out of 5
Flight:
I have only got to fly this rocket once so far. The initial flight was on a
Hypertek J317 with my GWIZ doing the deployment duty. The wind was light, only
about eight miles an hour. The fill and launch went perfect with a straight
boost and flawless deployment. My GWIZ reported 3789ft. Next flight is going to
be on the Pro54 K660.
Recovery:
Recovery materials are great, as there is a good amount of shock cord and the
parachute suitably sized for this rocket. All the hardware is first rate. It
was nice to see a kit rocket that really used quality components.
Flight Rating: 5 out of 5
Summary:
This is a well designed rocket and a very nice kit. All the components are of
the highest quality with nothing else need to complete a rocket that is more
than capable of getting you through level one and level two certification
flights. It is also a great rocket just for sport flying as it is very stable,
which allows for a vast amount of motors to be flown.
