Yellow Bee Testing Day

All preparations made, going to test plane.

Accused of having reversed controls. Actually, the wind was just moving the plane without any consideration of what the motors were doing.

Re attached battery, which flew out of casing when the plane crashed. That was the only issue, along with a loosened tail.

Yellow Bee project-Day Three-

We put Wings on the plane and anchored the motors-We had to find a new screw

Plane is completed

Yellow bee refurbishment, Day 2 (5/24/2013)

We are required to do some more documented battery testing (currently using battery 3)-

-Voltage before powering the plane at full throttle for three minutes:  5.20v

-Voltage after powering the plane at full throttle for three minutes: 5.02v

Need to attach the wing that we patched, and fix the motors in place. I found 1 spare screw along with the necessary 6.

I am fixing the piece that covers the otherwise open front are where the battery goes. Simplicity is beauty, so I just took the old broken piece and instead of fixing the attaching mechanism I made a hinge for it from tape.

Teacher’s Note: Don’t put fingers in propeller

Started work on rebuilding the Yellow Bee Today (5/22/13).

 We selected a plane to rebuild from the scrap at the back of the room. My partner has just suggested testing to see if the wires and connections currently in place still work. That makes sense.  We first had to test for a working battery and find a transmitter.

Teacher’s note: always turn transmitter on first

Wiring works, at least somewhat. We are letting the battery charge to see if underpowered-ness is the problem.

Attaching tail while we wait.

I should note, the antenna (which works, as we found when testing the wiring and circuit board) comes out the tail. Also, one screw which holds the tail in place is corroded.

Have to do something about the fact that someone wrote “swag” and “thug life” all over this airplane in past years (it was part of a class set).

Motor was sitting out of its socket. Not anymore.

Airplane motors work.

Transmitter 05 works w/ our plane.

Teacher’s Note: Look up the voltage of a fully charged Ni-MH 4.8 volt battery (what we use): 1.4v per cell while on charger, drops to about 1.25 when taken off of the charger
