My interest in RC began at christmas with one of those pico little helicopter things. it got me thinking, would'nt it be cool if I could use an rc aircraft to take aerial pictures and videos. I am a consultant ecologist and such a device could be a handy tool when surveying buildings and trees for bats etc. I bought a counter rotating helicopter to practice on which I promtly destroyed and rebuilt too many times! Flying, or rather crashing the helicopter made me realise something more stable was required. Next up was a Walkera UFO5 quadcopter, an intersting machine but too small (and weak ). I bought a couple of ufo control boards and made my own quad copter using brushless motors, it was much better, but I just couldnt get the reliability right and the firmware of the walkera ufo seemed less than perfect for my needs. So back to the drawing board.. I had been following the Bas10an tricopter build thread but i hadnt considered a tricopter until i saw Signguy was using one with an onboard camera. And thats when i aquired the parts to build my own.
