Ha ha
The girl at the supermarket that fills balloons showed me how.

Now I'm flying.
I have no rc.
The current problem: When the blimp is above shoulder height one motor spins.
Below shoulder height the other motor spins.
The blimp responds to a beacon with green leds but I haven't found a way to get it to fly towards it.
P.S. my props push air back over the motors. Is this good?

Props pushing airover the motor is usually good , it keeps it cool :)

Yeah - I have helium port questions also. E.g. do we need to seal it? Can we seal it and then add more helium later?

I have similar problems with autonomous mode (and no RC....). I have my motors connected so the "-" wire connects by the "ML" (or "MR") label on the board, but have no idea if that is right for either one. And the MR plug connects to the motor on the left in flying attitude - which seems wrong, but that is how their pictures have it. Needs more documentation.... How are yours connected?

The girl at the market that filled mine just stuffed a nozzle in. She said it automatically seals but can be refilled if you don't squash the bulge on the stem.

Oh and another thing. Our lit. tells us to stuff a straw in the stem if we want to fill out the envelope. Just blow it up.
