ESC cable extensions done

It is slow going for my big bird build, or BBB as I just called it.  I’m waiting for quite a few parts.  The work I can do now though, is wiring the power to the motors and wiring the motor speed controllers.

The speed controllers needed both their power and servo cables extended.  That’s done (below).

I can now start thinking of what to do with the power distribution board, and how to connect the ESC’s to the motors.

I tried to heat shrink with my old shrink wrap machine’s heat gun but that was like trying to use a blowtorch to light a cigarette.  Melted the wires.  May order a small heat gun, or maybe buy one of those blowtorch lighters…


Construction on the New Bird Has Begun!

What a Sunday it was…  After getting the basement, er… shop ready, I started construction on the new megahexactoper.  As of 10:45 p.m. last night, the primary frame and landing gear are assembled.  Like a newb I screwed up a few times, the worst part being putting the top plate on upside down and having to disassemble the damn thing and put it back together right side up.

The next goal is to get the motors installed, which won’t take long.  Then I need to make some decisions with regards to the placement of the ESC’s (motor speed controllers) and other items.


First Parts Arrive From China for New Bird

It has begun.  The first box of hexacopter parts from China has arrived.  Inside are six motors, six electronic speed controls (they control the speed of the motors), and a power distribution board to get power to said items.  The board even has some lights.  Cool.

I’m waiting now on the frame, a foldable 960 frame which is 1000mm in diameter.  That’s 3.2 feet wide for those of you who aren’t hip with the metric system.  3.2 FEET.  With the heli’s propellors the total width will be over four feet wide.

Also waiting on landing gear, battery mounts and the flight controller.  Ordered the flight controller today.  I picked one which is almost 2x the cost of the most popular brand, DJI, because of reviews I’ve read and comments about how stable the flight is.  The flight controller is from XAircraft America.

I’ve spent quite a bit of dough so far.  In fact, I’m just about dead broke now.  I may not be able to order any  more parts until I can rake in a little extra cash.  But the current parts list will give me plenty to work on.

Still deciding on a transmitter, having almost pulled the trigger on several units in the last three days.  They can go from $50 to $6,000.  The ones most suited for what I’m doing are $60-$400.  If I get the one I want, it will run about $400, plus I need to dump another $200 in sensors into the copter.  I can then have altitude, airspeed, direction, temperature, rotor RPM’s, battery voltage and all sorts of other cool “live” data coming back to my transmitter and displaying on its screen.

For some perspective, the motors alone for this mega-copter cost more than my entire DJI Phantom did.  Ouch.  That reminds, me… I need to put a bunch of old gear on ebay so I can raise the rest of the money for this beast.
