This week, we finally finished procuring all the necessary parts and started on the last phase of the construction, and the final shape of the aircraft began to show itself.
With a little more work, we should be able to start on the test flights (though the first step will be only taxiing and no flying....).　The parts that we worked on today was the, Rudder, Elevon, battery/ESC platform and the middle body support structure. The construction of the middle support structure was quite a difficult job, and we unfortunately did not manage to complete it exactly as designed, ending up with some tilt and unintentional space.....It became apparent that in order to achieve accuracy and smooth construction, a building support and careful　planning beforehand was required.... Something that we will like to improve on our work in the future. Other than above, we decided to change the thrust profile to a tractor style from the pusher style, since the building process turned out to be much easier, and there seemed to be more chance of successful flight in this way due to center of body mass and so on.
We checked the servos and motor behavior to end today's work.
With the construction of the wheels and a few more bonding... it will be time for some test flying ! 今週は、部品がすべてそろったため最後の位置合わせと組み立てに入りいよいよ形が見えてきました。あと少しの作業で試験飛行（と行っても最初は地上滑走試験）に入れそうです！作業として具体的にはラダー、エレボン、バッテリー+ESCとりつけ台、エレボン用サーボ、中央胴体構造のとりつけを行いました。中央構造は取り付けに少々てこずり、組み立てる際にかなりのずれとすきまを発生させてしまい、やはり精確な取り付けには部品の切り出し段階から制作性を考慮し各種治具や取り付け手順を事前に用意することが必要と痛感しました。また、全体の重心バランス及び飛行試験のしやすさを優先し、初号機ではプロペラ及びモーターをプッシャー式ではなく、トラクター方式へ変更しました。
最後にサーボ、モーターの回転をプロポで確認し本日の作業は終了となりました。
来週は車輪をとりつけ、残りの接着部を接着したのち、いよいよ滑走試験（飛行）です！
