はじめまして沼間在住、逗子ドローンクラブの内山です。職業説明会のイベントで、沼中の先生に本チャンネルを教えていただきました。ドローンを使ってとても面白いことをされているので、是非お会いしたいと思いました

すごい！ 向い風なのか、往路は中々進まなくで、見ててドキドキしました！

とっても素敵な動画です。 機体重量の少ない機体でここまでの動画が撮れることを知らないドローンユーザーはいっぱいいます。 これらの動画が多くの人の目にとまって、ドローンがより人気になりますように。

はじめまして。RunCam セッティングの4K@30fps_xviewはとはなんですか？何が違うんでしょうか？教えて下さい。

Very good and stable drone flight. Interesting shots. Great film editing. Good job. I fly too. Greetings from Poland. I liked.😊

Piękne widoki i świerny stabilny lot. Też latam dronem. Pozdrawiam z Polski.

うわー！U99で1㎞近く海上を往復ですか！！ 復路はバッテリーが持つか、ヒヤヒヤで拝見しました😅 脱帽です...

Beautiful view ♥️♥️🥰😍🥰

💯 'Promosm'

低く飛んでいるのですね。ぶつからずにするって難しそうだね

スローなのにアクロ飛行が出来て素晴らしいですね。キットにすれば売れそう！！

ご自分で作られのですね 素晴らしい

今５８歳逗子中OBです４０年以上ぶりなによりも全く変わっていない事に驚きました。動画ありがとう全逗子中OBみるべきですね。

Did you put capacitor on vbat?

So cool

in the future, fly with the sun BEHIND you, And the camera. i cannot figure out where the prop is. at 2:45, the tail is Heavy, because the vert-stab is Over-large, with too much slope at the le. the root chords of the stabs Should BE EQUAL. use a 75 degree slope, at the le. googletranslate

Nice place!

Very nice do you have a plan?

私はよく分からないが飛行機なの？ドローンなの？オリンピックの、　地球ドローン素敵でしたね。

何往復もするのですね

軽いのは良いけど電圧低くてもピュンピュン飛ばし過ぎてリポが再起不能にならないように・・・　(笑)

緑豊かで素晴らしい公園です。一つ要望があります。ゆったりした曲も合うのでは…？

迫力があってみてて楽しいFPV映像でした！ありがとうございます！

学校でレースが開催されているのですか。凄いね

observations. good work. however, some things are still wonky and some could, still, be improved. the tail Should be made LIGHTER. as Practical. it should be understood that there are Big benefits, to making the tail as Light as is practical.! said another way, there are good Reasons to make the stabs/control surfaces, Just large Enough, to be Effective.!!!! the height of the vert-stab Should be reduced, so that, the height is equal to a bit less-than fifty percent of the span of the horiz-stab.! the chords of the elev/rudder could be reduced, a little; say, five mm. when an offset pusher thrust configuration is used, the use of an Adjusted thrust Angle is called for.! see linked photo, for a typically accurate setup. (ignore the added cg labels) the existing, un-adjusted thrust line Is Causing nose-down moment, ANY Time that thrust is being produced.!!!! btw - as it is with any model, exceeding the trimmed-for airspeed/throttle setting, Will result in unscheduled Climb. googletranslate static.rcgroups.net/forums/attachments/2/9/6/3/9/7/a5988257-224-bixler%202%20motor%20angle%20correction.jpg

you may know that an airframe Should cg balance at Thirty percent of chord. if the tail is made lighter (obviously), the cg will need to be re-located. googletranslate

information. if the wing has a flat, no-lift profile/airfoil, the wing should have some positive aoa; this, in relation to the (pusher) thrust Line. googletranslate

the mass, of servos, can be put ANYWHERE, that is Best for the dom and/or cg balance. googletranslate

information. the vert-stab is taller, and Heavier, than necessary. i suggest that material be removed, so that, the height of the vert-stab is equal to a bit less-than fifty percent of the horiiz-stab span. googletranslate

ドローンも海の上へ飛んで風に吹かれて空中散歩楽しかったでしょうね

Buying this for my sons

very light. 18.3g. good job

if you wanna know what I know, see these MAE study notes (at princeton.edu) 'lecture1' thru 'lecture24' googletranslate www.stengel.mycpanel.princeton.edu/MAE331Lecture5.pdf

some info. good work. except, the tail is HEAVY !!! meaning, there is tail-heaviness in the dom. distribution of mass. the severity of this condition COULD be reduced, easily. doing so, would also reduce the auw. i have details if you want them. d googletranslate

some info. there are a few ways to make a light and durable wing. for discussion: this model could have had a slow-flyer wing. that is, a single-surface profile; mounted with positive aoa. (imagine, just the upper surface of the clark-y profile, in the exact same orientation; eg., a few degrees of positive aoa.) see a slow-flyer. googletranslate th-cam.com/video/lZ1vUKcktVk/w-d-xo.html 1.bp.blogspot.com/-5C8vhlmhBOk/VRe3o3Jt3yI/AAAAAAAABrI/EEgVHXkLvbY/s1600/clark%2By.gif does not have a slow-flyer wing th-cam.com/video/NGpkarsXn8w/w-d-xo.html

some info. i applaud the use of low-mass power and control components. however, when non-traditional building materials are used in the construction of a small model airplane, the model WILL be Heavy for its size. compare six ounces to three ounces or less. Instead of wing loading/wing area you should be concerned with: Reducing auw, achieving an optimal dom and cg, and making a good, dihedral wing; one that is Light and that Makes an Amount of Lift that is EQUAL to the auw of the model (at a given airspeed); with a minimum of drag: see the clark-y profile for the answer. note that if a zero-zero thrust line is used, the WING can be mounted with positive aoa. note that if a GOOD clark-y wing is made, (additional) positive aoa may not be needed.!!! note that a bit of positive aoa is built into a (clark-y) profile. aileron area and chord are Part of wing area/chord. the total wing chord is excessive and the wing profile/airfoil is rendered, wonky. googletranslate 1.bp.blogspot.com/-5C8vhlmhBOk/VRe3o3Jt3yI/AAAAAAAABrI/EEgVHXkLvbY/s1600/clark%2By.gif

sorry. you have, again, replied with mostly irrelevant information. 1) the mass of the main lg Should be located Below the main wing Leading edge. 2) the stabs are Too near the main wing, and they Are Heavy; because they are poorly designed.! 3) at :33, it is correct to use a few degrees of sweep, at the horiz-stab leading edge !!! 4) for a tail boom, USE a slender piece of WOOD. spruce or pine !!!!! 5) at 6.3 OUNCES, this model IS Heavy !!! 6) it is safe to assume that the main wing IS Heavy and that it has a wonky (span-wise) dom. 7) it appears that the wing has a less-than optimal profile. it is NOT a clark-y. and, the use of an over-long aileron chord Further Impairs wing Function.!!!! drive.google.com/file/d/18qulAf93OJU8dyawdEcgaxilf9WYL_d_/view WHY is it, that all you boys are INCAPABLE of asking ONE Intelligent question !!! instead, you ALL respond to accurate Observations, with irrelevant, anecdotal information. googletranslate 1.bp.blogspot.com/-5C8vhlmhBOk/VRe3o3Jt3yI/AAAAAAAABrI/EEgVHXkLvbY/s1600/clark%2By.gif

some info. the thrust config may be relatively okay. other issues include: the model is Heavy, for its size. the stabs and cf tail boom Are Heavy. stab size/area could/Should be reduced. the main wing chord is a bit greater-than is optimal. (so, more Mass in the wing.) the dom of the main wing is probably, wonky. distribution of mass. regardless of the things you have mentioned, the cg SHOULD be located at thirty percent of chord; or a bit forward of thirty. for indoor flight, this dihedral-wing model does not need (the mass of) ailerons, servos, etc. googletranslate

some info. (based on thumb-views, only) it appears that a less-than optimal thrust configuration is present. see linked annotated photo --- in which, center of Mass (c-m) is mislabeled as cg. the c-m is Supposed to be located at a point that vertically aligns with twenty-five percent of (wing) chord. where Offset thrust is used, a thrust Angle, at the motor, should be used, that causes the thrust Line to Intersect the c-m. said another way, the c-m should be located on the thrust line, at a point that vertically aligns with 25 percent of chord/mac. at linked illustration, observe that c-m is On the thrust line, and 'below' 25 percent of chord. this is also where a pilot's chest would be Located --- this by Design. not by accident or whim. googletranslate static.rcgroups.net/forums/attachments/2/9/6/3/9/7/a5988257-224-bixler%202%20motor%20angle%20correction.jpg s3.amazonaws.com/assets.flitetest.com/article_images/medium/truecg-jpg_1384168691.jpg

=== if this is your model, have you become aware of the several design flaws. it is probable that i have critiqued this model, previously. it should be understood that assertion of tghe presence of design 'flaws' is Not a matter of opinion. (neither are the, elsewhere-mentioned, design flaws Benign.) googletranslate

can you provide some specs of this rc model?? looks cool

きれい！

うちの学校やん

私今中学二年生なんですけど あ、ちなみにここの学校です

母校だ…懐かしい

Fantastic video.Stunning job !!! Thanks for sharing.Loved it! Great work.Iam now your channel subscriber.Don't forget to watch my channel too

ぐぁーと上昇したとこが良いね。 海ぽちゃは残念・・・

super nice

nice
