"I am thinking after watching promotion video of Inspire 1. It looks like enough that retractable camera and gimbal will protect and provide good sight for the camera. Perfect marketing gimmick!"

"4基で、176Kg以上の推力を得るのですが、約200Kgの重量とのことだと、浮きませんね。 浮上しているので、推力が当然勝っているのでしょう。  1) AC3.1.5は、安定版なので良さそうです。    -キャリブレーションは、APM 単体で事前に実行しないと無理ですよね。 2) Arming後、暫くしないと記録されないように、思います。 3) ここでは、少し不穏当ですが、他のFlight Controller の検討は、如何でしょうか? "

Here is a thread in Japan ArduCopter Group.APM powered X8 has more than 176Kg total thrust.Actually, Hirano-san is making this copter, not me:-(Hard to maintain hovering as you can see the video.There might be ground effect. Any suggestion of PID setting is appreciated on this big machine.…See More

Konbanwa!

What do you fly and is your field close to Tokyo? I'm located in Meguro and mainly into UAV aircraft, although just started to fly a KKmulticopter.

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/

Jiro, thanks for the suggestions on demonstrating the heli in Tokyo.  I might give that a try at the Tokyo Institute of Tech.  I guess the make fair is at the ookayama campus.  I'll ping you when I'm getting close to being ready..
