Techproaviation from Czech designed and is producing parts for Merlin and Merlin Lite. Many airplanes which have very nice flying qualities are designed and parts built by Techproaviation and then sold by different companies as their own kits or Ready To Fly airplanes.
With your permission, I will present a flying project of the Dbai aircraft, Kharkiv. My friend made it on the model of our two-seat X-32 aircraft. With the Rotax-582 engine, it performs most of the complex aerobatics.
