I'm having trouble programming the skywalker 40a esc that comes with this edf kit using beeps. do you recommend a particular led programming card?

Thank you for your question. Almost no programming cards are seen on the market, This can only be done with a remote control. We don't do control programs, so there is no better suggestion for this problem. I am really sorry that I have not helped you with the question.

動くのだが。

シャフトの一部に黒くなって、爪が引か掛かるような摩耗した箇所があり、絶縁チューブも画像のように。動作はキャリブレーション後、スロットを一気に上げると一瞬回転して止まりキャリブレーションするの繰り返しになる。徐々に上げると問題なく回転する。ESCやコントローラーは問題ないのだが・・・。追記・もう少し動作確認してたら、ESCが焼け焦げて壊れた。動作範囲内なのに。あーあ、失敗。
