This Kit Can Be Fabric or Film Covered
Optional Parts (interior, pilot, etc.) Are Available Separately.
See the optionals on the Accessory Completion Guide for these items.
Flaps: The SR-9 is designed to incorporate working flaps. However, flaps are
optional and not required for an excellent flying experience. With
-out flaps, the takeoff roll is a bit longer and the landing speed
is a bit faster. If you do not wish to build working flaps, simply
glue them into position. You will need these additional items for
flaps: hinges of your choice, two servos, Y-connector, servo
extension cords (if the Y-connector is not long enough).
OS FT-160: This engine is highly recommended and featured in the instructions.
It has ample power for even a 22lb model with scale appearance
Scale Documentation: Three-view drawings and photo packs of full size SR-9s
are available from: Scale Model Research, 3114 Yukon Ave
Costa Mesa CA. 92626 phone:714-979-8058.
The diameter of the prop on the full size model is 8' 3". That makes the scale
diameter 19.8". The prop we used on the OS FT 160 was an 18" x 6-10". The
engine could have turned a 20" x 6" prop as well, so a scale diameter flying
prop on this model is a real possibility.
Designer's comments regarding engines:
The G38 would be acceptable, though it is at the upper end of the power I would
recommend. The model was not designed for high power, high speed flight. It was
designed to replicate how the full size aircraft flew.
The G38 is a heavier engine, so this will increase the weight of the model. At
25lbs the model flies in a very scale like manner on the OS FT-160 twin. The
power rating of the FT-160 is 2 HP, so it is not that strong. However, it is
much lighter than the G38.
If it were my model, I would use an engine that is lighter and has less power.
If using the SuperTigre G3250 you would need an in-cowl muffler and
would indeed require extensions to get out of the cowl. The G2300
would be a better choice, but it would also require an extension.
Neither could use a standard muffler.
Aerotrend has some silicone
tubing that would work well. The G3250 and G2300 both have more
power than the model needs, so good throttle technique is a must.
The OS FT-160 twin was used on the original model and it also
required extensions, but doesn't require a muffler. A piece of
brass tubing was brazed onto the exhaust pipes of the engine. The
sound and noise level were very acceptable. The OS FT 160 twin is
by far the best engine for this model. It sounds great, has just
the right amount of power, runs beautifully and fits completely in

Per the designers the spinner used for the photos and the plans is the TruTurn
one for the AT-6 Texan.
