"That's the same tech I mentioned, and he's completely right. Not to cut your buddy out, but I already ordered from the manufacturer directly and they ship quickly.
One disadvantage: they're pure SMD components and they don't…"

i saw one of your post about a cheap quad, i have motors ESC frame, remote etc with me, but confused about board and sensors, can you plz tell me which board and sensors u have used?"

iPhone telemetry: a short tutorial
Posted on April 22, 2011 at 8:13am 7 Comments 6 Likes
Hello everyone,
After experimenting with tuning the APM, a friend (Roel Offermans) and I decided to implement telemetry. Even though it may seem counterintuitive to use a phone rather than an Xbee, when you already have the phone it saves some money. Another advantage is that it has 'unlimited' range,…

So after first connecting the engine the other way around, rain , and more rain, I finally managed to make my first flight in Stabilize mode. With just P-control on a Wingo clone, both at 0.06, it manages to maintain it's height perfectly, but it rolls around a bit.
Guess upping the P was a bit enthusiastic! I'm not posting anything revolutionary, but I'm very happy it flies :)
Picture of the APM mounted inside the plane, no video,…
