Long "abondoned" project.

inspired by rcexplorer.se this tricopter started as an idea roughly 2017 with leftover arms of an old ZMR250. i designed a fitting base & toplate, aswell as an 3dprintable tilt mechanism for a cheapish servo. after i got carried away, i eventually had some time to finish up my build with parts frome my spare bin.

in the future i want to add a small gps and try some big capacity li-ion packs with it.

STLS:

• tiltmount.stl: upper part of tiltmechanism. needs a servo horn.
• tiltbase.stl: lower part of tiltmechanism. servo is secured with a ziptie
• halstack.stl: mountingplate for RX & VTX. use heatshrink
• antennamount.stl: can be used to "mount" the R9MM-Antenna flush to the baseplate
• microcam.stl: mount for a 19x19mm microcam
• baseplate.stl, topplate.stl: frame parts, to be cut out of carbon
• arm.stl: just for reference, i used leftover zmr250 arms

Hardware:

• M3 Screws (click)
• M3 Nylon Locknuts
• 4x M3 Standoff 25mm (click)

Electronics:

i used what i had on hand. not really a lot of space in this build.

Current Software & PID-Tune

current pid tune is flyable, but not totally optimized.
