AT-6
Texan (April 2011)
I've been interested in some time to build an AT-6 Texan and with
some mad money in hand, chose the Seagull 1.20 AT-6. Power
is another Zenoah G-20 though I had considered strongly the DLE-20
given its recent popularity and reported good performance.
The Zenoah while slightly heavier and less powerful, is a proven
reliable engine and unwanted is any engine failures on a
warbird. The Zenoah will not be a hoss of an engine in the
plane, but should fly it more scale like, which is what is wanted
from this plane.
The build was typical of a 1.20 size plane except Seagull had
placed three servos ahead of the firewall and pre installed the
push rods. These were ultimately relocated to the wing
bay for isolation from the ignition but doing so proved to work
well when balancing.
A friend had a set of retracts that he offered and they were
considered. They were sturdy and would drop in but didn't
provide for angling the gear forward, which I felt was a necessity
on our field so went with the stock struts.
As the spinner for this plane was quite expensive, a large prop
nut was made as an alternative.
During the Fall of 2011,
the AT-6 suffered the most perfect cartwheel I've ever seen of a
model. It suffered a bounce on landing which put it back
airborne about four feet where it then stalled and rolled hard
about 90 degrees, caught the right wing tip, tripped over the prop
nut and then impacted on the left wing tip and bent the spar back
and in the process compressing and crushing the center wing
section. The following shows the not too difficult repairs.
