Twin Fan is modified to single 70mm EDF (reconstruct motor mount ) . Weight save ~200g. Hoffman Magnetic 1400W @4s. Thrust 1700g!
Inlet duct will soon be modified to collect air into the single fan.
Wait to modify to full motion canard.
Setting: 120A ESC, 4s2p (2200mAh),
All up weight including 4s2p (2200mAh) is 1600g.
Benchtest Hoff-mag. with 5 blades (WeMo clone), with intake lip: thrust 1700g.
Inside fuselage thrust test, with exit cone~1400g (300g thrust loss)
I drill some holes on the attachment area of the fusealge and the main wing to get more contact area. The single piece of wood to whole the main wing and fusealge looks weak. But after applying sufficient epoxy, it feels secure.
Exit cone is cut to adapt single EDF.
