"残念ながら、回答になっていませんね。 Logを、別の見方をするとLoiter投入で数機のMotorがストールしています。(見ずらいので、一部表示) 気圧計が、どんどん上昇していますが、本当に上昇していますか? Flipした後も、上昇しています。 傾向から言って、墜落中の気圧変化と、断定できません。 "

"Power Module は、搭載していらっしゃるようですが。。。 それで、電池関連の解析結果ですが、電圧低下とスロットルの入力の低減が見られます。 1) 慌てて、スロットルを戻したのでしょうか? 2) Hexaで電圧低下すると、横に流れるように墜落した記憶がありますが、どのような堕ちかたですか? 3) GPSのエラーも表示されているのですが、Glitchは、不明。 4) Vibrationの状況も、始めは非常に良いです。"

I'm living in Atsugi. It looks like lots of space to fly air craft in Atsugi. However, there are very few places to flay.

This is my main frustrated issue. You can visit my web site. It is some sort of language translation web site. http://aeroquad.at.webry.info/
