The Pitts S2B kit by Airshow Models.Com is the second in a series of aerobatic aircraft by this new company. The S2B is a certified production aerobatic trainer and display aircraft produced by Aviat Aircraft of Afton, Wyoming. This aircraft is a descendant of the original Pitts Special designed in the late 1940s by Curtis Pitts. The Kit
Two
vacu-formed canopies are included…just in case.
The propeller and spinner in the pre-production kit was of white metal
but a resin unit will be available. Construction I started
construction by soldering the forward cabane struts together.
These are aligned by small pins and holes cast into the struts.
Superglue will work here but I wanted extra strength.
I also soldered the two control columns to the aileron torque tube for
the same reason.
Final
Assembly The
interplane struts were epoxied into the slots in the lower wing and then the
upper wing was installed before the epoxy had set up, giving a perfectly aligned
model. The use of epoxy allows for
the extra strength required in handling a resin biplane.
The photo-etch landing wires, parts A and B were installed using
superglue with the small end at the cabane strut fairing and the large end in
the recess in the lower wing. The
flying wires, parts C and D were installed with the small end in the slot in the
top end of the landing gear leg and the large end in the recess in the bottom of
the upper wing.
The aileron “Spades”, PE part #1 were added to the bottom
of the lower ailerons(omit PE part #2..use the supplied
piece of airfoil shaped plastic strut material).
The upper tail brace wires PE 4 and lower brace wires PE 5 were glued in
place. At this point I glued the
aileron slave struts into place to avoid breaking the sighting devise, PE 6.
This latter part has slightly enlarged tabs on the ends of the mounting
arms and these should be bent at the middle of the tab so that they can be
wrapped around the left interplane strut. I
glued the sighting device to the strut with superglue then used tweezers to
pinch the tabs around the strut. The pitot
tube supplied with the kit ended up in the jaws of the thing under my desk, so a
piece of hypodermic needle was installed on the lower left wing.
The propeller/spinner were finished and installed,
and all that is left is the canopy which will be in the closed position.
The canopy PE parts 8 and 9 are installed on the inside edge of the
canopy with the slanted end forward, aligning with the rear edge of the canopy
bow frame. If properly installed the rectangular cut-out will fit the
canopy support and virtually lock in place. Javelin
struts between the flying and landing wires are
supplied with this kit in the form of
small diameter plastic rod. Conclusion: This kit was as mentioned, a preproduction kit which I had to put together to prove Pete’s ideas and be able to come up with a construction manual for the production models. It went together in about 12 hours and it proved to be quite an easy build. There was very little flash on any of the parts and the removal of the pour stubs was not difficult.
The
mouldings have a slightly rough texture to them but a bit of wet sanding with
400 grit paper will provide a very slick surface.
All components fit beautifully without any modification and by taking the
time to carefully assemble and paint this model, you will come up with something
really spectacular. And it will
stand out along side the other models in this series. Article and photos by: Barney Dunlevy Models
