R81 FrSky, facile da montare, ottimo compromesso qualità prezzo, a meno che non si cerca un "bando labirinto" o il long range, è davvero difficile da mandare in failsafe. Il trasmettitore da battaglia/test perfetto.

Arrived quickly in a two weeks from China warehouse, very well packaged in bubble wrap and antistatic bag, just perfect.. Excellent quality little receiver, cleaned PCB and there's no soldering flux or acid, just ready to go, only 0.9g, antenna interface is (IPX4, IPEX4, MHF4), D8 protocol (FCC) with SBUS output, channels 1ch-8ch are controlled by the remote controller, channel 9ch is output for return RSSI telemetry (and it seems to work very good), fast and easy binding, tested it in range of about 500-600m without any breaks in connection, very stable and I believe it would get 1km with small modifications.. I'm little disappointed by the price now, but in these days everything is going to be more expensive than before!

arrived in Greece quickly, about 6 days after the order. very small and light I have not tried it yet because I received it today but I will come back when it tries. the only downside was the packaging, it had no protection at all and may have crashed during transport.

軽い 小さい 安い(^-^) 前回購入分は1つは問題無く働いてくれてます 500m半径以内ではバインド切れもなく RSSIの状況もいいです それを超えての受信感度は不明です 通常の飛行では 問題無く利用できる製品だと思われます ただ私はアンテナケーブルは交換してます ストックは細く短いです それでも500m以内では問題無い様ですが 木々に回り込むとRSSIの数値は乱れが強くなります アンテナケーブルを変更すると 乱れる幅が狭くなります この距離を超える場合や木々の間やストラクチャーに入る際はCrossFireを搭載した機体に変更するので 通常のレシーバーでの守備範囲としては十分に働いてくれてます 前回購入分のもう1つはバインドモードに入らず使えませんでした それを踏まえ今回も2つ購入しましたw まだ信頼をしているレシーバーにはなってません ですが 魅力のあるレシーバーなので3インチ以下でしばらくは試してみようと思います(^-^)

Great tiny D8 receiver. The small size makes it easy to install in any airframe. RSSI telemetry on channel 9 works well. Great range comparable to the XM+ but better because it’s not an Frsky product.

D8プロトコルのレシーバーで出力はSBUSです 8chまで自由に利用でき 9ch目にRSSIが出力されてます 基本的にはjumper R1を利用し 今のところ不自然なバインド切れや不都合ありません 出力も16chでHD機にも対応でき 安定感・安心感があるため 今のところR1を基本構成にして行きますが コネクターがあるため少々大きく重いのがデメリット 90mmサイズのクワッドにも搭載してましたがスペースはギリギリでした 最近ではtinyhawk2freestyleにも搭載しましたが かなりギリギリ入った感じでした (VTXを変更してからは余裕で収まってます) tinyhawk2freestyleに刺激され さらに良く飛ぶU99をビルドしようと このレシーバーをチョイスしました R1より小さくコネクターはありません 軽くて安いです(^-^) アンテナは細く短いので2.5インチには丁度いいかもです (私は少し長く太い物へ交換予定で注文済みです) ロングレンジではない様ですが 300m(GPS計測値)程先にある木の間や鉄塔に回り込んでも問題なく動作してましたので 10ドル程のレシーバーとしては申し分なく 上出来ではないでしょうか(^-^) これからは基本はR1を搭載し どうしても入らなければこのレシーバーで対応していこうと思ってます(^-^) ちなみに 2個購入し1個はバインドモードに入らず使えませんでしたw 安いから2個追加注文しましたw
