:cool: Aloha to all, and Merry Christmas to everybody else.
I'm an older, (never old!) retired chef,hippie, bachelor, and general widgiteer. I just bought myself a first generation BR at Safeway for the outrageous price of $49 USD. First thing, before attempting to fly, I read everything on this forum (Jeez, what a lot of reading!) Now that I have the equivalant of a PHd in all the problems and fixes (?), I am ready to build a flying saucer, using the BR design concepts, coupled to (never mind what-[trade secret]). I have everything I need except 2 micro-gyros. I would like to find a 3-axis unit, (if such a creature exists), or 2 biaxial gyros. Anybody have any knowledge about such thingies? If I can create a micro-size working model, then I will scale things up to about 1 meter diameter. Of course I will have to acheive the equivelant thrust/weight ratio as my design model, but for now a micro-size model will get me going.
By the way, after seating the brushes on the motors and cycling the battery 6 times, I was able to get a 6 minute flight (in a 3 mph breeze). My instant-read mechanical food thermometer registered 102 deg.F when touched to the can. Just a hint: A reflective surface on the motor cans will reflect heat inwards, just as it reflects light outwards. Thirty years ago, as a slot car freak, I learned to sand the exterior of the cans in a cross-hatch pattern with 600 grit paper (creates much more surface area) and then color black with the now-ancient refillable felt tip markers that my school teachers used to redact some of my hand-ins. Do not use paint-it acts as a thermal block, instead of a conductor.
To make a short story long, THANK YOU Petter, (and everybody involved) for putting such a wonderful device into the hands of those of us who have more cents than dollars! Now, if the rest of the world could follow suit~~
