Today I flew my new RC Trainer and successfully tested some autonomous flight modes.
It was originally planned to be a twin engine version for the last year competition, but it was cancelled in favour of much better all-new design.
However, last month I crashed the first Trainer airframe and decided to complete abandoned airframe to replace the old one and fix some of its issues.
I made substantial improvements for this already successful design. It got fibreglass skin, detachable horizontal tail, new 3D printed mounts, extra side-looking GoPro window, Crossfire antenna buried inside of its fin.
I even made an autonomous low pass in GPS mode
So I finally got an extremely durable, reliable and versatile workhorse for almost everyday use.
