AMAZING XXXL RC Glider RC Beljajew BP-3 50% M 1:2 SCALE [4K] MARKUS FREY AIRSHOW FLIGHT INTERVIEW


Welcome dear friends of Modellpilot.EU! Today we are here with Markus Frei. Markus Frei has built a beautiful model. First of all, thank you for being the one Scene so great perform. Please like to happen. What is the motivation? Yes, the motivation of the plane was really an older colleague now to do a favor. So now really to make an old gentleman happy. And the Lord was? That was Frederick Fischer, actually the founder of the Swiss interest group Albatros for vintage gliders, and that has the Beljayev BP-3 in the scale 1:20 and 1: 6 actually wanted to build one Model in really big and is approached me with this little request. Really big what is the scale As she stands behind us now, on a scale of 1: 2. That is, what is the span of the original? The original has 20 m wingspan and about 2,80 m wing depth and weighs just over half a ton. What was she actually built for? The BP-3 was used for training for future bomber pilots, because Victor Beljajew still has built a 2-engine bomber with the same wing geometry as now the BP-3 and from the BP-3 became 6 Piece then used for training at the Russian Navy. Most will wonder that’s a flying wing. Works with S-impact profiles or with the original profile, does he make the profiles himself? How is that regulated? that the center of gravity remains stable? Yes, I’ll tell you how it always is such projects, you never really build alone. So here I was professional help. I have a good colleague there Dr. Helmut Quabeck, known to many, I have come to the rescue. He, too, had been stunned with such a project because from the whole design of the model it was pretty special. Especially in what regard? The 7 degree prewar, scarce 10% thin profile with the S-beat, then additionally the two rudders, low-lying elevator, so the whole interpretation The model is very unique. Because too all the aerodynamics in the back, if that’s me Elevator is a bit lower than that Root attached, under the main wing appropriate. Was there a bit of belly-brooding, is the plane flying or not flying? I was so fortunate that I have for Frederick already BP-2 is the predecessor model of the BP3 could build in 1: 6, also the BP-3 in small and the two were already right to fly in a hurry. But I already knew it flies on the whole and could then with an almost good conscience to the big ran. Yes dear Markus, Thank you for your insights. And finally as is always said with model pilot: Model flying is: great!
