Bought one from hobby lobby the add says superpowerful ect. Put it together as instructed weighs 16 oz as it should.
It will not fly hand launch sinks to the ground if you try any control movemrnt smash into the ground.
At full throttle the prop is turning 5k . Now one problem I am trying to fly it at 7200 ft . Anyone had any experience with this plane ? Any suggestions? Larger prop? Or should I take my lumps & put it on e-bay?
The wingo will fly up here with the bigger prop suggested. electric gliders wil fly stock but sluggish with just enough power to parly climb

The plane is underpowered at 800 ft. too. One of our indoor flyers
couldn't get it to climb off the gym floor. I think your right about
either a longer prop and or more pitch. Along with the prop trick,
try 8 or 9 cells of the 720 mah AAA NiMH cells. Don't be afraid to
overpower the motor unless you've got a 5 amp ESC, in which case, you'll have to go up to a 14 amp. As in the Zero, too many
of the planes simply won't fly on 6 or 7 cells. Any of the foam jobs
, you hate to see them heading downward after launch. Don't
give up on it yet.

Contact Hobby Lobby service dept for advice by e-mail. They may want you to return geardrive for service/upgrade. May be binding in gear drive or defective motor.

Also try 8 or 9 cells and an APC SF prop.

The thing should at least fly reasonably well.

Had better idea sold it on e-bay to a guy on the east coast. It maybe will fly at sea level. Hobby -lobby tried to be helpful but imho i was just putting money into a dead horse.
