A few photos of the air screw installed. Moreover, the shape of the spinner appears to be different. The specifications of the blade were also guessed based on the unclear photo.
It looks like A and B use different blades and different spinners.

There is no data regarding the tail structure, so we are guessing based on the influence of the skeleton that appears on the outside. The structure of the side radiator is also just a guess as there are only vague photos.

尾翼構造は資料がないので外観に出る骨格の影響を元に推測しています。
サイドのラジエータの構造も不明瞭な写真しかないので想像です。

I guessed the structure of the pipe frame considering the weight of the engine. Since it is a racer, there are fewer rubber bushes on the engine mount. I needed a little curve in the frame to avoid the cylinder and supercharger, etc. I emphasized it a little too much, so I plan to fix it. I considered several ideas to connect it to the anchor in the center frame, but this shape was the most reasonable, and moreover, it resembled the frame for Renault’s inverted V engine.

エンジンの重量を考慮してパイプフレームの構造を推測しました。
レーサーなのでエンジンマウントのラバーブッシュは少なめです。
シリンダーや過給器などを避けるため少しフレームにカーブが必要でしたす少し強調しすぎたので修正予定です。
中央の骨格構造にあるアンカーに接続するようにいくつかの案を考証しましたが、この形が一番無理がなく、しかもルノーの倒立V型エンジン用のフレームに似ています。

1. Adjustment of air intake and windshield height
2. Adjustment of engine position and cowling shape
3. Float position (slightly lowered and the back half slightly thicker. The bottom fin has not been installed yet, so it looks thinner than in the photo))
4. Adjust the position of the base of the wing
5. The tail has been made slightly lower and wider both front and rear, and the rudder in particular has been extended rearward while emphasizing its curvature.
6. The main wing attachment angle was changed from 2.5 to 2.3 degrees.

1. エアインテークとフロントガラスの高さの調整
2. エンジン位置とカウル形状の調整
3. フロートの位置（少し低く、後ろ半分が少し厚くなっています。まだボトムフィンが取り付けられていないので、写真より薄く見えます））
4. 翼の付け根の位置を調整する
5. 尾翼は前後ともやや低く、幅広とし、特に舵は曲率を強調しながら後方へ延長。
6. 主翼取付角度を2.5から2.3度に変更した。
