SBJ-1

January 4, 2018|F.K1999

Happy new year for everyone! I want to tell you about my new and unusual model, that I flew first time at the last day of 2017 year. This plane refracts my view to conception of next generation SST. I think it must be rather small capacity, but long range and luxury private airplane. It also must be able to reach high lift to drag ratio on any speed: 2 Mach and 0,9 Mach (high subsonic speed must be used for flying above populated areas). I made several variants of design and number of gliding models since 2016 year. This year I made final and very unusual design. The main feature must be adaptive wing with folding wing tips (XB-70 style). Very primitive foamy glider flew very well for it's size and quality. Then in October I started to build RC plane

The model was not difficult to build however due to some reasons it was ready to maiden flight only 31th December. I was surprised that it flew successfully from the first try. It was very stable and predictable to control. Here are some flight photos and video:

But the adventures are not finished! Soon I will try to fold its wings mid-air! I will install similar wing tips to my fighter model (you can see it on one of these photos) and try to simulate this flight mode. Then I will try to do it on this plane. I also want to make landing gear for it, because landing speed and mass (near 1 kilo) are quite high. Here is some information about size and electronic: the engine is an Impact 1400 kv 2215 , prop is 9/6 APC , ESC is an Impact 30A , and the battery is 3S 900 mAh. Length and wingspan are near 1400 mm. I hope you like this article!
