완전히 비행기 1대 자작하셨네요. 대단 하십니다. 궁금한것은 앞날개와 Aileron 은 (Joint?) 어떻게 연결하셨나요? 저도 40여년전에 만들어 놓은 (목조) 세스나 를 Aileron 을 만들어 붙이고 전기모터 달고 날려보려고 합니다.

멋진 영상입니다. 비행기를 제작하셨군요. 러더도 필요하군요. 제가 알던 (지금은 고인) 747 비행기 기장 말로는 실제 비행에서 러더를 쓸일이 없다고 하더군요. 글라이더에 모터와 배터리 그리고 카메라 까지 탑재를 하고 비행을 하는군요. 대단하십니다. 영상 잘 보았습니다. 감사합니다. de AG5QF

주말 잘 보내셨는지요? 관심에 감사드립니다. 네 맞습니다, 사실 모형비행기에서도 러더 쓸일이 별로 없습니다만, 수상기로 사용하려면 러더가 필요하기 때문에 러더까지 포함시켰습니다. 수상기의 경우 물에서 뜨려고 할때, 러더가 없으면 이수가 어려워 지는 경우가 있더군요.

I'm not sure that I would have wanted to take a trip with your Ex- 747 pilot mate though! Landing a laden 747 in a cross-wind might get a bit "interesting" without a rudder. 😉😊

sir, an electric prop should not be noisy. when an electric prop is noisy, it is an indication that the prop that has been used is Too flexible, for the application. a drone rotor is not a prop. a 'stiff' EP prop should be used. 009 when a vertically offset pusher thrust configuration should include the optimal location of the prop and the use of a correct adjusted thrust angle/line. neither of these things have been done. as a result, the thrust configuration produces unscheduled nose-down moment, whenever there is thrust. you may have trimmed the elevator, as Required, to compensate for this thrust issue. if so, that elevator up-trim is making 'extra' drag, All of the time. sir, there are overlapping 'rules' that guide the correct design of an aircraft; of any size. in addition to correctly locating the cg at thirty percent of chord, an aircraft's center of mass (c-m) should be located at a point that vertically aligns with twenty-five percent of chord. that point should also be located on the thrust line. said another way, the thrust line should Intersect the c-m. the linked photo shows an optimal offset pusher thrust configuration. there is, however, a mistake in the annotations. the added lines intersect at the point where the c-m Should be located. , however. that point is where the c-m Should be located. googletranslate static.rcgroups.net/forums/attachments/2/9/6/3/9/7/a5988257-224-bixler%202%20motor%20angle%20correction.jpg in this illustration, correct c-m location is indicated. s3.amazonaws.com/assets.flitetest.com/article_images/medium/truecg-jpg_1384168691.jpg in each case, the location of c-m is described as i have stated.

Thanks for a nice advice, I am happy to hear this kind of technical information. Yes, I still have an issue for nose down issue, when motor is accelerated. I did not try to compensate with the elevator, but gave ~ 10 degrees up trim for the motor. However it still has a habit, although it has been greatly improved. I may need more motor up trim??. In addition, when it goes vertically, it has a habit of straying to the left. Currently I am trying to compensate it with a rudder. It may need additional motor side thrust?? Please let me know your thoughts.
