OK I confess, I didn't build this!! Roger's A400 from Tony Nijhaus plan but bought ready
built and powered by 4 electric motors. Sadly came to grief
during the fourth flight and is no more!

Roger's A400 in flight video (to play click on the
picture) and here is a very large
RC A400 (38Kg!!). The A400 has a
unique engine rotation configuration to create an airflow over
the wing aptly named "down between engines" making the real
A400 more stable.
The turboprop arrangement has two turbofans on either side
of the fuselage. The counter-rotation of the fans creates a
symmetrical airflow over the wing to improve the lift capacity,
handling, and stability. Additionally, it reduces the structural
weight of the wing and minimises the adverse yaw in the event of
an engine failure.
For the model, I concluded it was
somewhat too heavy for it's wing area, it was prone to
instability at lower airspeeds. Keeping it stable meant an
unrealistic airspeed and fast landings. It initially had no
flaps - modified with flaperons seemed to help but a trial at
"sensible" slow speed ended in a tip stall and disaster. If
you build one, proper flaps are a must!! |
