手持ちのバッテリー、BETAFPVの2S 350mAhでレビューしています。

Caddx ANTはやっぱり綺麗

見やすいと評判のCaddx ANT。この軽さでちゃんとCaddx コントローラーを使ってOSDで各種設定が出来るとか凄いっす!


RX LOSSという不具合

今回、飛行中のRX LOSSに悩まされました。症状が出て居ないところだけ繋いでレビュー済ませちゃおうかなんてのも頭をよぎりましたけど、きっと解決出来る不具合だと信じてあえて公開しました。



  • ファームウェアを4.2.2にアップデート
  • 噂のプロトコルRedpineを試す(反応が良いFAST、リモート距離が稼げるかもしれないSLOW)


ホント、Crux 3はリモート距離「だけ」が難ありで、2Sバッテリーってやっぱり扱いやすい(普通にUSBで充電する充電機とか、マルチチャージャーとかも豊富にあるし、バッテリーそのものも割と普通に買える)ですし、それでいてパンチも滞空時間もあるので、フリースタイル練習にも良いと思うんですよ。

そんなこんなな意味で、Crux 3はToothpickの代表格になり得ると思います。ほんと、リモートの件だけ。
