"i read somewhere where they shimmed the the bottom of the motor mount to correct the thrust line problem might be worth a try"

"Hi Dan, I am also just starting out with an FPV plane. Which plane did you end up buying?"

"http://hackedgadgets.com/2009/09/30/high-altitude-glider-project/ This guy used to have a great website devoted to his glider drop launches. The site is gone now but he made great progress! Although he never really got it to operate properly there…"

"Ben, I am not a coder either but I do from what I understand believe you can use any GPS unit with the APM if you know how to send the proper signals to the APM. Currently we have not progressed far enough with the APM to worry about it yet. I have…"

"Fantastic! "

"Just as a note: You can purchase a GPS unit and apply (It's not hard) for the limits to be removed so both the speed and altitude limits are removed but it does cost $2000 for one of these from http://www.novatel.com/ The reason I know these…"

"Not true! There are several that have the ability to go higher than 60kft The Lessen IQ will do atleast 106,640ft I know that for a fact! :)"

"The odds of hitting anything are very low. Every day they launch 2000 Radiosonde's to 100k and I've nevere heard of one hitting anything."

"Are you sure it would be overstressed? I've thought about this and I'm not convinced. Speed doesn't stress, drag does. The speeds are so high BECAUSE of reduced drag forces. To induce an equal force at lower density requires higher…"

"Lipos will work in fact they work the best for the money. The GoPro has LiIon batt. They work fine. Actually heat becomes a problem with electronics at these altitudes any transmitter will get very hot if your not careful! I have taken a gopro to…"

"Dan   Your Bixler wont handle the stress being dropped from 60-100k one of my payloads hit over 450mph falling from 100k. 40k might be doable with some reinforcement.I'd suggest a modified SkyFun instead even that would be a…"

"Johnny is right. There are a lot of amateur high-altitude balloon launches being done which are recording GPS data between 60,000-100,000+ ft. The majority of gps modules won't allow it, but there are some out there that will. I came here…"

"ok because at my other house I have a real landing strip aprox 1.5km long 150m wide just grass so hopefully I can launch at a footy field and let it fly and land at the in used runway"

"+1 - I would like this as well."

"I have taken part in two balloon launches. On one, I built a photography satellite using a box of around 5" x 5" x 5" made of foam board. Once all of the "guts" were installed, foam padding was used to insulate and restrain…"

"A comment on wing mounted motors --   I tried the nitroplanes UAV (55") and a slightly beefed up 3xx42mm motor. The thrust line was too strongly down, and the plane wanted to fly outside loops.     So even if the pod is big…"
