V-22 Osprey kit is here!
Building mine now
I can tell you at first look, I'm favorably impressed with the kit! Had to get back to the office. More later.
The profile fuse is a laminated foam board. VERY sturdy! The picture doesn't do it justice. It has the all of the panel lines impressed in it. Looks great.

RE: V-22 Osprey kit is here!
There are four bearings in bearing holders in each wing that the nacelle conversion arms ride in for rotation. You red locktite the bearing into the holder then epoxy the units into the wing. Later versions will have these pre-installed. Either way this is a step on the road to first flight for me.
Note the panel lines impressed into the wing surfaces.

Splicing in the capacitor onto the ESC.
The additional capacitor adds capacitance due to the longer wires from the battery that's mounted on the fuselage. The power wires from the battery go through the wing and out to the speed controllers out in the nacelle. Castle recommends the additional cap. Note that there are already two stock caps factory installed. This helps control DC ripple when a switching amp is in the circuit I'm told.
Note capacitor polarity. Most caps have a stripe down the side indicating negative. Also the negative lead is usually shorter than the positive one.
You poke a hole through the insulation, I use a pointy exacto knife. Watch your fingers. Once the blade is through I spine it to spread the wires to help get the cap wire through.
Remove some insulation on the opposite side for soldering.
Use a needle nose to push the wire through and solder the back side.
I added the shrink on the cap leads. This was not in the instructions. I just don't like bare wire showing.

OK got most of the nacelle wiring completed. The ESC's are mounted as well as the wire distribution board. Did a trial fit of the cowl. It's snug. Won't need many screws to hold it on.

Building up the aft section.
Remove the paint..
Temporary jig.
Glue aft section to empennage
Start mounting components onto profile fuselage...
Needed a mount for the GY520's
Wings test fit.

Added tube spacers in the wing mounting holes. I didn't like the compression when tightening the two wing mount screws.

RE: V-22 Osprey kit is here!
Remember all of this stuff gets covered up inside the fuselage once all flight testing is complete.
BTW: I chose Futaba gear because I like the simplicity of the system and the reliability of FASST.
Checking CG. It's perfect!

Flight Control Description
There is also a pitch governor that reduces pitch as power requirements exceed motor capability. This only engages in airplane mode and only above a preset rpm.
As conversion takes place the Helicopter Mode Controls transform into Airplane Mode Control.
Aileron is accomplished with differential For/Aft cyclic of swash plates.
Elevator is accomplished with For/Aft tilt of both swash plates.
Rudder is accomplished with differential Collective Pitch of both swash plates.
Speed control is accomplished with symmetric Collective Pitch change of both swash plates.
In Helicopter Mode swash plate movements are:
Roll is accomplished with differential Collective Pitch of both swash plates.
Pitch is accomplished with For/Aft tilt of both swash plates.
Yaw is accomplished with differential For/Aft tilt of both swash plates.
Vertical control is accomplished with symmetric Collective Pitch change of both swash plates.

Explanation:
During conversions collective pitch is dependent on airspeed. As the ship converts the controller will intentionally over apply collective pitch. When the pitch governor detects RPM below the set value it will pull back collective pitch to prevent a bog. As airspeed increases the governor will allow higher airspeed. To effectively tune this setting an on board watt meter is necessary (max continuous of 400 watts).

RE: V-22 Osprey kit is here!
Man, thats great and the Q bout crashing if any motor fails then it'll glide it because of the airfoil which creates lift so the worst is your gunna need a new body

RE: V-22 Osprey kit is here!
I got the thing powered up the other night. Got all the latest firmware and software loaded along with the controller settings.
The nacelles are tilting. Got them on channel eight using the slider controller on the side of my 12Z. Need to do some adjusting of the nacelles. Got the ESC's programmed. Only thing left to do is set up the gyros. Waiting on the USB link for the GY520's to make that job a little easier.

RE: V-22 Osprey kit is here!
OK boys and girls, I finally spent a little time on my Osprey this weekend. I'm 100% powered up now. I have the heads running, the conversion servos setup and working along with the control servos. Everything looks to be going the proper directions. I had to reverse one of the motors.
Here is a video of the grand moment....

RE: V-22 Osprey kit is here!
Unfortunately I had a very rough year with job and family. Things are just getting somewhat normal again. It basically sat for the whole year. I'm just now getting ready to get back on it. I have all upgrades including the just released retract kit.
