"GPS の感度が低いとの疑惑から、2ndGPSを搭載してみました。 感度の差は、明確に出ないので地理的な問題なのでしょうか? 尚、GPS1のhdopが悪いとGPS2が良くても、Armingできません。 画像が大きすぎたようですので、小さくしました。 *無謀にもHK450ProにAPM2.5搭載中ですが、ラダーのトラベルと中立設定が不明???"

"このように、配線していますでしょうか? 尚、Switch science 側の端子の外側の例です。 ビデオは撮りませんが、4台のPixhawkにこの配線していますが、1-2秒で接続可能です。 "

"xBee 同士の設定を一度完了していれば、他の機械に持って行ってもコムポートコムポートの設定に誤りが無ければ繋がると思います。 状況として。。1) OSD等の併用,2) 距離が離れていて、電波が弱い 3) Mission Planner 側で、テレーメタリー設定を弄った。(通常触りません) 4) テレメタリーポートが、違う。 5) DF13ケーブルの断線(偶にちぎれそうなののが有る)や接続不良 でしょうか?"

"920MHzのモジュールが、何時の間にか秋葉原で売っていました。 インタープランのM920無線モジュールです。 http://www.interplan.co.jp/solution/wireless/im920.php 千石通商やAmazonでも購入可能です。 問題は、高速モード:50kbps、長距離通信モード:1.25kbpsと、以外と低速なのですが、2.4GHZでないことが、一番重要かも知れません。 "

"I could upload AC3.2rc11 on my APM1.0 by Mission Planner. The result is; 1) Mediatek GPS is not recogized 2) Baro meter becomes crazy, climbs up more than 20,000m high:-( Unfortunately, I have removed compass for APM2.0. "

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/
