This Pitts AV has been extensively worked on. Everything has been tweaked so it excels at High alpha 3D flight. Everything from Rolling Harriers, waterfalls, knife edge spins, blenders, front and back flips and hovering are rock solid. It tumbles extremely well and still feels like it's on rails. If you're into flying 3D you should love this one. In low rate it's a very stable sweetheart. Either way this thing is a blast to fly.
Smoke is on channel 7.
High/Low rates are on channel 5.
All the rest are the normal channels.
There are a number of different camera views that have been added to make thing interesting.
Also, different color schemes are available.
Have fun and enjoy.
