My second FPV

1.2m glider, detachable wing. Looks like multiplex glider. The main wing is reinforced with 8mm fiberglass tube. I make 2 pieces of neodym magnet at the contact point of the 2 pieces, such that no tape is needed to have a quick installationin in flying field. The package indeed comes along with all the small things you need, including the Y-cable, push rod, linkages, ... The foam is better than EPO, a new foam material HPC?
The front compartment can handle 3s 2200mAh, 3s 800mAh, video transmitter ...

Wingspan : 1127mmLength : 830mm
Fuselage + electronics weight : 430g
3s 1500 + 3s 800mAh (for video ) :230g
Camera +Transmitter : 50g
Total flying weight: 800g
2200kv , 5" propeller
Handles wind much much better than my previous BusyBee FPV.
I did not make a pan/ tilt camera for time saving, and from my previous lesson of not using a separate UBEC for 5 servos operation.



The stock outrunner sucks and half of the magnets migrated.
Remember, this glider has relatively small aileron control surface. It needs very large travel in order to have sufficient control on roll axis. Not even dream to have a complete roll.
