you can build a tricopter using ap2000i and 3 gyro. attached is the picture of how it is wired up. check it out. I am building on using cdp4 and y-ufo board, but it will have to wait until I am done with all other projects. (too many) my DF based quadrocopter is flying and well. the frame is available . it is usable with UVAP board as well as mikrokopter board. it is setup with epp1245 prop (which is having some durability issues from others) but can lift heavy load. with well tested 1045, it will still lift over 1lb payload with 10min flight.

I've done some lift test with 1245/DT750 motor setup. my setup without battery is 35oz. I've tested today at 67oz and 84 oz total weight. at 67oz, it flys very smooth and nicely very easy flying and feels very steady even in wind on my DF setup with gain at 50k. At 84oz, it feels heavy and definitely need more tuning. feels like driving a overloaded truck. I will limit my weight to 70 oz or so, which will give me 35 oz of load. my new miniHD gimbal weighs in at 4oz, so that gives me 31 oz. 3S4800 pack weighs about 400gm (14oz) that leaves me 17oz and over 10 min flight time. MiniHD gimbal can carry any camera upto 5" wide by 3.5" tall. (canon a640 size) typical downlink and OSD/GPS adds about 5oz, leaving us 10-12 oz for a nice camera. I am running Panasonic Lumix FX35, which weighs in at 5oz, which put me at 65oz total weight. I am also finishing up my UVAP setup. the...Continue Reading

this one has been troublesome, but finally I am getting close to completion. here is basic framework. the servos and camera mounting plate has to be mounted still, but overall, basic frame is done. dual belt driven setup makes for smooth pano polecam. making it adjustable while rigid was not easy, but it is done. another project being finished up finally. I have logo 600 nosecam to finish up still.

oh well. no rest for this man.
