A few months ago, I posted some video and pictures of a tilt-rotor quadcopter called iQuad. Since then, I've been working on building a new version of iQuad which is lighter, has a cleaner design, and adds FPV. The new iQuad weighs 1600 grams w/o batteries (down from 2260) thanks to a carbon fiber body and custom-built rotation mechanism and landing legs. My goal for this version is to achieve faster forward flight and eventually add 3D-printed wings to get airplane-like flight characteristics.
The previous iQuad used unmodified arducopter firmware, with the tilt servos being directly controlled by one of the channels on my radio, which limited the tilt angle at which the APM was still able to produce stable flight. For this version, I am going to control the tilt servos directly from the APM, for which I'll need to write some custom firmware. (any help would be appreciated as I am new to arducopter development)
Here are some more photos:

im going to be using 4 sunnysky 3525-520kv motors with master air screw 13x8 3 blade props
servo city parts list cost $395
ok so I just ordered all the parts to build one from servocity $395 not counting ESC s motors or flight controller and batteries. funny thing is I had designed it alot like yours long before I found your video. I was going to build a manned drone tilt rotor but I think I will start small. I'm using beveled 90 degree gears instead of the gears that you used and a frame made from servocity channel aluminum. it will have a tail and wings for forward flight. motors will tilt forward 0-45-90 degrees with a switch but with the switch at zero the right stick will have control of tilt. if the switch is at 45 or 90 degrees the right stick will have no control over tilting but only control the tail and wing control surfaces. I am thou wondering if in a bank turn in aircaft mode will it matter if the FC is trying to right the craft even thou the motor are facing forward? won't this cause the nose to tip up? I think this can be cancelled with programming the FC to go to a new set of PID settings when the switch is moved to full forward flight.
Hi,
did you make any progress on the handling of the of the tilting from the APM ? I'have the same interest in a tilted approach.
Thanks,
Stefano.
This is a test wing but it gives you a better idea of the scale.
