Looks Good Earl do you get frost or condensation on the inside on the way up? How is the glider launch coming?

good post!

Glider is put together. Shooting for mid July.

Dont know about frost. Should put a camera inside with an led light.

Hi,

I launch my glider with the balloon this week. I'm not sure yet what mode should I switch on the APM 2.0... Should I simple set the RTL mode?
I do my launch on friday at 05:30 am and hope to get some very nice pictures and my plane back than.

I am going to do RTL on mine.

Please share APRS.FI call sign and launch schedules beforehand - like to follow upcoming missions in real time.

Earl you mentioned you had a radio failure did you find the source ? The reason I mentioned condensation and frost is because I had a radio failure in a plane once in the winter It worked fine one day it was already cold  It got extremely cold that night  the next day it wouldn't fire up. when they disassembled it they figured condensation had formed on the circuit board from repeated heating and cooling and when it got extremely cold it froze and lifted the foil off the circuit board  breaking the contacts you might have had a chip freeze and split when it warms up the frost goes away leaving the damage and you trying to figure out why? You are doing interesting stuff  Have a good day Earl

Great work, guys!  My group is planning a 90k balloon launch, to release a glider with APM2.  A few questions:  1) what make/model glider are each of you using?  2) do you know what the current, in-place FAA regs are for such a flight?  The Small Unmanned Aircraft System Aviation Rulemaking Committee, in 2009, made recommendations (which might put our plans in the grey zone, possibly requiring a waiver), but I don't know which recommendations were actually passed into law.  Anyway -- I'll follow this thread.  I hope you all share APRS details, and other tidbits.  I certainly will!  --Prahas

The callsign for our balloon and glider flights is KE5VSH-1

I will try to make announcements in the arduballoon section 2 days before flight.

The glider we will use is an X8. No motor, not needed, with aprs onboard as well as the APM2 and 3dr 433mhz radios controlling the rc stuff with a joystick in mission planner via the mavlink connection. No rc rx installed...not needed. We will also have 5 watts of live video on 439.25 mhz. A tv set to cable channel 59 with a 12 element beam antenna to show FPV from glider. We plan to fly back from whatever altitude we get to. We will have a cut down circuit via mavelink..

I gotta go now to get some sleep for school in am.

I do my launch with a selfmade flying wing. 2 keycam #16 onboard and the apm 2.0 and a gsm gps tracker. I let the apm control the all the flight.
