Hi All
It's been a while since I was on here but gained some great help when building a heavyweight battle bot a few years back so thanks for that. My next daft project is to build a terminator style Hunter/Killer aircraft with no moving control surfaces The last time I flew an RC aircraft it was a box of balsa with wings and a petrol engine and the word 'Drone' didn't exist, MUCH HAS CHANGED!!!!!!! if give a rough outline of what I'm trying to achieve would someone please advise on the best thread to post a more detailed question???
HOVER MODE
I'm planning on an aircraft that uses 3 EDF motors (one on each wing tip and one in the tail) so it takes off using a flight control board like a tri-copter drone (all motors thrusting down) so take off is achieved simply by increasing thrust (HOVER MODE). The left stick Y-axis (vertical) controls all 3 motors in tandem so back = swing thrust forward resulting in backward motion, forward = turn thrust aft resulting in forward motion. Right stick X-axis connected to a rudder on the tail EDF motor so when hovering left/right spins the aircraft left /right (in flight mode it works the same as a plane rudder)
FLIGHT MODE
Left stick Y-axis all the way up puts all motors into horizontal rear thrust thus moving from reliance upon downward thrust for lift to forward motion aerodynamic lift of the wings. Left stick X-axis counter rotates the wingtip motors (so where a port aileron would go up and starboard go down the same motion is achieved by redirecting wingtip thrust in those directions). So far in flight mode we have ailerons, thrust and rudder covered leaving elevators, this is where right stick Y-axis comes in, forward = wingtip motors tilt thrust slightly up and tail motor shifts thrust slightly down - causing dive. Right stick Y-axis backward does the reverse causing climb.
THE BIG QUESTION
The rudder is simple - right stick X-axis = rudder left right BUT¬
Tail tilt servo has 2 inputs - Left & right stick Y-axis
Wingtip tilt servos have 3 inputs - Left stick X & Y axis + Right stick Y-axis
HOW???????? HELLLLLP! Using a Skyfly T6 controller BTW but thinking I'm going to have to mix Arduino with standard RC kit which scares me a bit
Cheers
