Congratulations and thank you for purchasing the Great
Planes Ryan STA-M ARF. We at Great Planes R&D were
pleased with the appearance and performance of the
original red, white and black civilian Ryan STA and are just
as pleased with this military “M” version. In fact, a couple of
minor improvements make this plane our best ARF yet.
Although not intended to be an all-out scale model, the
Ryan's classic design and two-cockpit layout make it
tempting for enthusiastic modelers to spend a few extra
hours adding even more details (such as cockpit controls,
flying wires, panel lines, etc.).

When it's time to fly your STA-M, you'll be as pleased with
its performance as you are with its appearance. During test
flying, it flew so well that we had to actually try to make bad
landings! And every time the Ryan went up, local R/C club
members stopped what they were doing to watch this model
fly. The STA-M's greatest attribute–and what you can expect
when you get your model in the air–is its nostalgic
gracefulness. Make sure you have plenty of fuel in your field
box because when it's time to fly, you'll be needing it.

For the latest technical updates or instruction manual
corrections to the Ryan STA-M, visit the web site listed below
and select the Great Planes Ryan STA-M ARF. If there is new
technical information or changes to this model, a “tech
notice” box will appear in the upper left corner of the page.

The Great Planes Ryan STA-M is an excellent sport-scale
model and is eligible to fly in IMAA (International Miniature
Aircraft Association) events. The IMAA is an organization
that promotes non-competitive flying of giant-scale models.
If you plan to attend an IMAA event, contact the IMAA for a
copy of the IMAA Safety Code at the address or telephone
