"Though I have seen many videos of people doing it. I guess you can be lucky most of the time but not all of the time."

"You can't compare a Stryker to an X8. For a start the winglets prohibit any type of wing launch method. The there is the weight. Forget all attempts at hand launching an X8 they are doomed to failure or injury."

"This is the cheapest and safest way to launch an X8 All up about $30 worth of materials. http://www.youtube.com/watch?v=KfVhfR4Cj_Y I have never even considered hand launching mine."

"Don't want spoil a good video but this video seems to endorse playing in flood waters. In Australia the message is never to enter flood waters no matter how safe they look. That should be the message to the rest of the world as well."

"I think it was removed as an OPTION. It is now always manual_level. This is the only option ever used for level on a plane. At least I presume that is what was meant. I have never tried to not use manual_level."

"Yes they did!"

"Those wings seem to flex up and down a lot, especially in that landing shot. "

"Flew my X8 with the 2.73 firmware yesterday. This navigation control is excellent. The aircraft now loiters in a perfect circle with the default settings whereas with the prior version it loitered in a square. It hits every way point exactly and the…"

"I would tend to disagree with first setting up stabilize however. I made sure everything worked in manual by mixing the radio. Then used the reverse options in mission planner to get stabilize working. Just my thoughts though."

"I tend to agree that the text is wrong it should be 1 to port and 2 to starboard. I recently pulled everything apart and when I plugged it all back in, everything was OK in manual but stabilize was wrong. I thought something else must have changed…"

"The plane will not restart the same mission just by switch to auto again after completing the mission. You can issue a command via telemetry to Restart Mission. As far as I know this has always been the case."

"I think we need a few more details. What is the airframe, standard 4 channel? Another thing to check is make sure the APM has the correct orientation."

"Also the latest version switches to circle for a short while as part of RTL I think. That may explain the seemingly random elevon deflections as well as the attitude problem. "

"On my X8 initially stabilize would lose altitude very quickly and even loiter would too. I had to level the plane in a fairly pronounced nose up attitude to overcome these problems. I think what looks like level to the X8 on the ground is really…"

"Seriously build yourself a bungee launcher for about $30. The X8 is far to big and the prop far too dangerous for a hand launch in my opinion. http://www.youtube.com/watch?v=KfVhfR4Cj_Y The above video is my bungee launcher built for about $30 If…"

"Hi there According to your tlog file there is no GPS attached to your copter. Did you check the GPS status before setting it on its mission?"
