Here's a building log of my second "tricoplane" project (POGL-019) .
I received many good advices about my first one, the POGL-018. After about 10 flight tests I decided to stop the development and to rethink the whole concept keeping the original goal.
To conceive a VTOL airplane capable to hover perfectly and to as well offer a natural plane behavior in horizontal flight (with the usual inputs). To provide smooth and lithesome transitions and likewise to be capable to glide and land on a runway. All this without tilting parts.
Epilog of the Tricoplane v1.0 POGL-018see attached image
The v1.0 was a tricopter hybrid airplane. Wings were fixed and tilted at 25°. The rotors were all fixed. This configuration was providing very smooth transitions and the possibility to float at a certain limited speed. Very limited speed I should say and that is the reason why I stopped its development.
For a moment, I thought to tilt the wing at maybe 40°to get much more of the horizontal thrust vector but I changed my mind. Even at 40°I'll still have two vectors and the wings will still fight against the acceleration inputs which is draining inefficiently the battery.
Two of the goals were achieve : Perfectly hovering and offering very smooth and easy transitions.
