The T-6 is a modified version of the Pilatus PC-9 build by Beechcraft in the US. It is 33 feet long, has a 33 foot wingspan, and stands about 10 feet tall. It’s powered by a Pratt and Whitney Canada 1000 shaft horsepower turbo prop engine.
The T-6 cruises at 364 miles per hour and has a range of about 1000 miles. As a military trainer, it is stressed to take 7 positive and about 3 and a half negative g’s which is just a bit huskier than the venerable Tweet.
The Unique Models version is 47 inches long, has a 47 inch wingspan and is powered by a 3648 640 Kv electric motor with a 40 amp ESC. Unique recommends a 14.8 volt 2200 to 2600 milliamp hour battery.
These dimensions make the model about a 10 percent scale model.
The model came out of the box in good shape. The fit and finish were both good and it looked nice. You can tell this is an older model in that some of the assembly was less complete than more recent models where you basically just need to screw on the tail and connect the radio and screw on the wing.
As you can see in the assembly log, you’ll need to mount the control horns to the control surfaces and other such tasks. For me, that’s not a bad thing. I like to assemble the small parts and planes that go together in 30 minutes just seem to have cheated me out of the opportunity to build the model.

The PC 9 flies pretty well. With a little trimming the plane flew straight and true.
I have been having some servo flutter issues though. I’ve replaced servos, changed receivers and the leads going out to the ailerons with no success. The next mod is a new ESC to see if that is the source of the noise that causes the servo to twitch. That twitchiness in the air makes for an exciting flight with lots of control inputs. When it flies well it’s a joy and looks great. When twitchy, it’s the devils child.
Here’s the video of the build.
