| = Name = L.I.F.E.kopter is the MK Project of ["SelectaT"] L.I.F.E. stands for: '''L''' (symbolizes the [http://en.wikipedia.org/wiki/Glider_%28Conway%27s_Life%29 Glider] in Conway's Game of Life) '''I''' nverse '''F''' rame '''E''' xperience ... and of course for [http://en.wikipedia.org/wiki/Life life] and all around it!!! = Forethoughts = Based on the standard MK setup (FlightCtrl, BL-Ctrl 1.1 with hi-power MOSFETs) I decided to try an inverse frame (propellers under the frame) for two main reasons: * pushing props are supposed to be more effective than pulling props because nothing (no frame, in this case) is in the way of the streaming air - result: fewer swirls, higher efficiency, less noise (hopefully!) * the frame ends (extended around rotors) can be used as rotor protection and feet at the same time (picture follows) Apart from this, you can now use larger more UFO-like caps because there is more room on top of the frame ;-) = Notes = * 06/02/08 got me all the parts and a MC-16/20, started soldering (first time SMD) [[BR]] * 14/02/08 soldering for a week now, in what little spare time i have; not too bad, getting routine [[BR]] * 18/02/08 almost done with BL-Ctrl!!! [[BR]] * 22/02/08 tested and flashed BLctrl, all 4 thumbs up!!! attachment:sebas_regler.jpg [[BR]] * 28/02/08 tested and flashed FlightCtrl, everything OK here too. And now for the frame... [[BR]] * 29/02/08 on this rarest day of them all, my frame is getting in shape! I decided to start out with the ordinary (non-inverted) frame to test everything and learn to fly... [[BR]] * 03/03/08 last night at 1 a.m. sharp my kopter did its maiden flight. after ~8 hours of wicked wiring it took off in LiGi's living room and hung there for about 3 minutes (Ligi on the sticks, there was quite limited space). everything seems to be as it has to. did a few hops as well. now for the cap and some landing gear, think for a start it'll be the noodle style for me. *#&% weather!!! supposed to stay like this for 2 weeks now. [[BR]] * 05/03/08 had a finishing session last night and now it's official: it was worth it all! exactly 4 weeks of work (and fun), and in the morning today i had a first outdoor flight in the rosental park. it was wuite gusty so the drift was a pain in the ass, but i managed to do a few tipsy laps. tonite as the (for now) final act the lower styro ring will be fixed. ---- KategorieNachbauten |
