30A Brushless Speed Controller ESC for RC Helicopter Airplane Multirotor(Pack of 4pcs)

It works very good and has a good price

light weight

This speed control does what it needs to

Went up in smoke on the first flight. One of the mosfets totally fried to a crisp. Will post the pics later.

acceptable for money, checked them ok, but didnt use them really yet

These have worked out great for me! I would definitely purchase again.

Good buy, arrived quick

Bought these as a way to avoid buying a new a 4 in 1 esc. Tried and tried and tried even more, but had no luck getting all 4 to functions. Seems like a few would work, but the other 2 would not. Wasted money and time. No matter what I could never get all 4 to work. I can only guess that 2 of them were bad from the very start.

あまり評判が良くなかったので購入には慎重になりましたが、一応問題なく正常動作しました。ただ付属のマニュアル（紙1枚ものです）が他社品のものでした。私は偶然コピーされたマニュアルが示す正規品を持っていたのでビックリしました。使い込んでいないので信頼性はわかりませんが、他社品のマニュアルをコピーして同梱している事実から、この製造元は信頼できません。

使えないと思いました。重いし、コロナなら、殆ど動かせるが、フタバの受信機だと全く動かない。電圧？詳しい事分かりませんが、値段以下です。
