Why 95% scale and not 100% scale?
question somebody asked when I was designing the plane was, “why not just go
full scale? What is the point in downsizing to 95% scale?” The
answer here is quite simple: cost and simplicity. After all, most
people can’t drop 100k on a full size replica just to spend 10 years building
The D-Motor LF-39 and Rotax 912UL/ULS are the current front-runners
for engine options. Because these options don’t offer the big power of a
Menasco, Tigre, or LOM engine that a full size ST would require, a weight
reduction was mandatory. Less weight means less power required which means
we now have less expensive engine options. No need to plunk 30k on a
Menasco and then worry about parts availability.
Right now, our empty
weight estimate is at 740 lbs, but we can get up to 795 lbs before we match the
original ST-A full-fuel useful load. So it's looking like we will have a higher
carrying capacity, despite the lower gross weight. The gross is set to 1260 lbs,
so with 125 horsepower, we will have a higher power-to-weight ratio than the
ST-A and a lower wing loading. In addition, flight duration should be slightly
higher and the baggage area is much larger. Shoulder and leg room are increased,
as well. Pilots of 6'5" have tried on the ST replica and have confirmed
the cockpit is roomier than the original.
So, it is a small difference
in size with huge implications on weight, performance, cockpit size, and cost to
build/operate/maintain. Even parked next to a full size ST, most people
will never notice the size difference. That 5% is the difference between a
$50,000 replica and a $100,000 replica.
How many hours will
it take and how much will it cost to build this plane?
about 1000 hours for construction and about $45,000-75,000 US for a finished,
flying airplane. The biggest cost factor will be the engine used and the
ability of the builder to scrounge for inexpensive (but airworthy!) parts.
Compare that price to a self-built hot rod, and the numbers are roughly the
same, maybe a bit lower for the airplane (cars are expensive). When we
first set out to design this plane, our end-goal was to afford people the
opportunity to build a replica of one of the most desirable aircraft ever built,
but at a price roughly two-thirds that of other modern LSA kit-built sport
I am a big person. Will I fit the ST
The replica was designed to take a pilot as light as 150 lbs and
as heavy as 230 lbs. We have confirmed the cockpit is actually roomier
than an original and will fit somebody at least 6'5" tall (and likely much
taller). WATCH YOUR WEIGHT AND BALANCE!!! This airplane
will not be forgiving of weight and balance negligence.
kit come with an instruction manual?
Of course! Too many people
purchase plans, look at them once, and immediately throw in the towel. We
don’t want that. Our instructions are as complete as we could make them in
one go and outline the project step-by-step. If anything is unclear in the
instructions, be sure to call us and ask to clarify. Your answer will be
immediately recorded and will be added in future versions of the manual.
This method will keep our instruction manuals as clear and up to date as
I have never built an airplane. Is this too
difficult for me?
Don’t ever tell yourself something is too
difficult. The key to completing a project like this is to jump in and
deal with problems as they arise…ONE AT A TIME. Yes, problems will
arise. You are building an airplane, after all! But when those
problems creep up, treat them individually. When one task is conquered,
you are ready for the next. The included instruction manual also helps to
keep things going smoothly, outlining the order of operations and showing you
how to deal with manufacturing methods.
What does the ST-L kit
As of writing this, kits are going to have pre-welded and
powder coated subassemblies, pre-cut and formed aluminum parts, and pre-drilled
parts wherever possible (a lot of drilling must be done on assembly to assure
perfect fitment). It is our goal to keep the kits as straight-forward as
possible. After all, we want these planes to be in the air, not abandoned
in a dusty garage. Keep in mind, though, that the builder must meet the
FAA's 51% rule, meaning they must complete a certain number of tasks.
avoid unnecessary price hikes, some items are not included with the basic kit
and must be purchased direct from the supplier. The order form has a list
of things not included and the build manual will have a list of recommended
engines are recommended for this airplane?
There are a lot of engine
options out there. Right now, the best engine options for the plane are
the D-Motor LF-39 and the Rotax 912UL/ULS. Don't worry! We've gone
to great lengths to keep the narrow look of the cowl even with a D-Motor or
Rotax. You will not be disappointed with how the cowl looks. There are
also other options, such as the Mikron IIIC, Turbine Aeronautics turboprop, and
How accurate is this replica?
This replica is a
fairly faithful representation of the Ryan ST, ST-A, ST-A Special, PT-16, PT-20,
and ST-M. It will be all-aluminum with optional cowlings and fairings of
fiberglass or aluminum, depending on the builder's tastes. However,
certain things had to change to bring the weight down and make manufacturing
easier. For instance, the bulkheads are not of original-style
design. The bulkheads were designed with a different flange style.
There are various other small differences, but we strived to keep the outward
appearance as accurate as possible, along with the overall look and feel of the
interior. Some notable changes are: modern airfoil, simplified
elevator trim, hydraulic brakes, better tailwheel geometry (easier to handle on
the ground), non-steerable full-locking/full-swivel tailwheel with simplified
design, modernized landing gear toe-in/toe-out adjustment, modern lightweight
wheels, simplified shocks that are lighter and easier to maintain, simplified
wire attachments at the lower landing gear, simplified modernized control
systems, and aluminum I-beam wing spars (the original ST had wood spars).
This replica retains the original-looking flying and landing wires with the one
strut above the wing stub. All-in-all, it is a modern airplane that is
very-well disguised as a classic.
Can a PT-22 replica be
made from this Ryan ST replica?
This is an easy answer that becomes a
complicated one. While the Ryan ST and PT-22 look similar, they were
vastly different designs. You can make a PT-22 “look-alike”, but not a
replica. One plane you CAN replicate was the predecessor to the PT-22, the
PT-20A, another radial-powered design that had much more in common with the
What variants can I replicate from this
There were many variants of the Ryan ST that can be replicated
using this 95% scale plane as a foundation. The variants are ST, ST-A,
ST-A Special, STM, STM-2, PT-16, PT-20, and PT-20A (radial-powered). In
addition to those variants, other oddball things have shown up on the original
STs, including bubble canopies and a sliding canopy that was supposedly
developed for Canadian planes.
What types of rivets are used on
The airplane was designed with a mix of solid rivets and
Cherry rivets. Solid rivets are just as easy to use once you have a small
amount of practice. Rivets used depend on the part. There are many
areas where only solid rivets are acceptable, so please follow the plans
Will this airplane hold its resale value?
difficult to predict any market. As of writing this, it is our opinion
that the airplane will have excellent resale value once completed. After
all, the only other option is to go purchase a real Ryan ST at a price of
Do you have other airplane designs in the
We always have more airplane designs in the works. Some are
replicas, some are new original designs. It is company policy to keep
pending designs under wraps until the time is right, but check back regularly
for teasers and new information on upcoming plans. As of right now, all we
can say is, "just wait 'til you see what's next."
Where did the
company name “Timber Tiger” come from?
The term “timber tiger” is a slang
word referring to a chipmunk. Our first airplane in the works was the
aptly-named Timber Tiger STOL, a light sport bush plane. That project was
put on hold to complete the Ryan ST replica. We are currently on our
fourth re-design of the Timber Tiger STOL. We want the plane to be as
refined as we can get a light sport bush plane.
