Mr Mulligan has flown, well at least across the room.
It now weighs 2.5g with a new Full River 10mil cell and bahoma connections to a cut down Tanaka IR receiver. The new Sharp SMT IR sensor allows elimination of a lot of components, PCB and weight.
Unfortunately I was doing a similar lightenning job on another receiver and dropped it onto the polished floor, and two days of searching have failed to find it. I accused the dog of eating it but he admits nothing. Such is life in the micro electronic world.

Not many posts but I have been spending some time with my indoor models.

I have resurected my Infra Red Tanaka gear and am trying to fly my 4 inch Mr Mulligan. Since giving up a few years ago I have removed the gearbox and balsa/plastic prop and installed a micro copter tail rotor. A new SMD sharp IR sensor also saved some weight and bulk. But it is still almost 4g with a 50 mil lipo and that is too heavy. It seems to be stable but does not hold height. Hoping a new 20 mil cell on order will improve potential.



I am inspired enough to have bought some new 4mm pager motors as I think my old ones are getting sick. Metal brushes just do not last. The deH Comet will get back to life with any luck.
