well, I've decided that I want to concentrate on smaller folding quads/y6.(upto 2kg auw) I have a proto quadcopter flying with rectangular geometry and it flies like a dream with KK board. will be testing a folder out with uavx. I also have y6 built with kk, but it is bit harder to fly and orient. put it down hard due to loss of orientation. have to replace a shaft or two.

anyway, got the first frame cut. I want to build a pair of them. one with KK and the other with UAVX/roll/tilt stabilization.

been working with UAVX and now I am prett happy with how it flies. (thanks Greg aka gke for the latest firmware) I will continue to work on this as my base platform. I really think UAVX could be a great setup with new ARM processor board and 10DOF from drotek or one from canada (can't remember the name, but was selling for 75 bucks) MBED being 60 plus some form of shield requirement makes it bit tough. really need ready to go board that cost about under 50 bucks without needing extra board (similiar to seeeduino mega) current UAVX at 40mhz is usable and decent board, but getting old.

anyway, spent some time compiling the list of available fcb with features, as my desired features are : acc/gyro, good alt hold and camera stab. no real desire for GPS/Mag sensor as all my flying will be relatively close. (and from what I've seen, GPS is still not really reliable on most units)

AD-50q: (foxtech) acc/gyro+ camera stab about 160 USD. just came out. no real field result available. closed firmware

multiwii/miniwii: 70 euro for miniwii. acc/gyro optional compass/baro (bma085baro cost 20 bucks) camera stab plus trigger available. v1.9 has decent alt hold. arduino/atmel based. open firmware

opencc: ARM based 90USD acc/gyro. + early camera stab . open source firmware. no baro.

afrocntl: acc/gyro/baro. no camera stab. 10000 yen (about 130USD) C based code. requires PPM RX. I2C esc or I2C to PWM...Continue Reading

been flying HK-KK setup for a while now and been really happy with v4.7. so, I started to build my new AP rig.

I really need to build a good camera mount for this use, but I have adapted what I have, which will be good enough for taking stills and hopefully fixed video. it is bit flimsy for my taste. still, it will get me going and allow me to test the new frame.

so far, weight is at 480 gm with FCB and some wires. motor esc should add about 450gm. so lets call it even 1kg plus batter and camera. 1.5-1.7kg auw. so far so good.

I will need to design a new camera gimbal. probably with belt driven tilt for this one. I may add belt driven roll as well if I am willing to add bit more weight. we will see. once design is proven, I will cut it out of CF for that added rigidity.

after running AskmanAP for 5 years, working 2 jobs without time off took its toll on my health and marriage. I was facing high blood pressure, chronic fatigue as well as nasty gastro intenstinal disease as I gained lot of weight during this time. The final straw was issues I was facing with my family life, and I had to stop the ever speeding wheel I was on.

I really want to issue a formal apologies to all the customers that supported me during the years. My life was so bad, I had to walk away from the business to salvage the rest of my life.

fast forward 3 years.

I am back down to healthy weight (and looking to get down to 10% body fat), my family life is back on solid footing and I am healthy again. I am slowly getting back my interest in the RC - multi rotor, but really no desire to go back into the business. I will be posting all my old G-code used to cut the mount and put it into public domain. Sorry I don't have any DXFs as I designed them all in my head and hand programmed into Gcode.

It is good to be back. and I beg forgiveness of everyone and thank those who cared abut me.
