Kelly's Brio build and pictures
I thought it would be best if I didn't clog up Don's "Brio by the numbers"
thread with my first time pattern build so I am starting this thread.
I decided to use a OS 140rx in my brio and today I worked on the
motor mount and nose ring.
I purchased a Hyde A style motor mount. This mount does not require
a nose ring but I decided to add one in case I use a AR type mount.
I made the nose ring out of aluminum with fuel tubing installed around
the ring. I made the nose ring support out of 1/8" aircraft ply.
Here are a few pictures.

RE: Kelly's Brio build and pictures
After reading about heavy rudders and cracking hinge material
I decided to built the new one. I went with a built up rudder
instead of a foam core (it was just easier for me).
I had purchased CHP control horns and ended up having
to angle them in a little to make the pivot over the hing
line.
Once everything is covered I think it will look nice.
The rudder came out at 1.7 oz.

RE: Kelly's Brio build and pictures
Here are a few pictures of the landing gear supports I
added. I made templates from cardboard and transferred
that to 1/8" aircraft ply.
In the pictures they are just tack glued in place. I will add
epoxy with milled fiberglass (thank's for the tip Dave) later.

Chin cowel.
I decided to use small 2/56" bolts to hold on the chin cowel. I added
some light ply pieces to prevent the fuse side from crushing when
the bolts are tightened.

Canopy.
For some reason the dowels that hold one side of the canopy in
place had been cut off flush. I decided to install new dowels
facing forward instead of the back. This way if the screw comes
out the canopy will just fly off without possibly popping up,
catching a bunch of air and doing more damage.
I used small fiberglass dowels instead of wood and reinforced the
dowel pin holes with 2 layers of ply.
I also added a couple of ply disks at the mid point of the canopy
to help with the alignment.
At the back I used a single 4/40" socket cap screw that is
recessed into the canopy to hold it down. A steel washer is
built into the recessed hole.

RE: Kelly's Brio build and pictures
Thanks guys!
I worked on the throttle servo the other night. Nothing
special I mounted the servo to the side of the Hyde
mount as I had seen done several times.
One small change.... I threaded the aluminum angle
and captured 4 2/56" socket caps screws in place with
2/56" nut under the servo. This will allow me to use nylon
locking nuts on the 2/56" studs and I will be able to remove
the servo for service at the flying field without having to have
access to the heads of the 4 socket cap screws.

RE: Kelly's Brio build and pictures
Enigine is now mounted and the cooling inlets are cut out.
I also mounted the wheel pants and wheels.
I mounted the engine a little sideways so the header pipe
would be closer to the pipe tunnel center line.
As it turns out I can reach through the front of the plane
and get to all 4 of the engine mount screws and remove the
engine, mount, and throttle servo as one complete unit.
Next I will mount the pipe once it arrives.

RE: Kelly's Brio build and pictures
After a lot of hair pulling I decided to go ahead with the DEPS
for the elevator.
Once I decided on a location for the servo rails I built a servo
mount out of aircraft ply and balsa. Then spent a lot of time
working out the pushrod exit locations and building the ladder.
This was my first DEPS and it does take some time to do, but
the next time it will be a lot faster.
Next up is the pull pull rudder.

RE: Kelly's Brio build and pictures
I finished the DEPS and completed the pull pull cable exits
at the same time. Once the tubes had been located I tack
glued them in place with thick CA.
I then made 2 light ply and balsa fillers to fill in the tail servo
holes and glued them in place with epoxy from the inside.
I used epoxy mixed with milled fiberglass to coat the inside
of the tube exits. I gained access through the rudder post
I had removed earlier in the build.
Once everything was dry I sanded down the tube exits flush
with the fuse sides.

RE: Kelly's Brio build and pictures
Pipe mount in the tunnel.
I had never done a pipe mount inside a tunnel so
I had to think about it a while.
After a few quick drawings I cam up with a mount
that is light weight and easy to install. It will sandwich
the nomex floor of the Brio pipe tunnel and can be bolted
in place without having to go inside the canopy.
The pictures can explain it better then words....
That white plastic peice is just a spacer for testing and
has nothing to do with the mount

RE: Kelly's Brio build and pictures
This is my first composite airframe and paint job. I have painted
cowels and wheel pants and the underside of my Mustang.
Honestly when it comes to paint I have more spray equiptment
then talent! I used a Basecoat/Clearcoat
The lines are straight but the camera makes them look jagged.

RE: Kelly's Brio build and pictures
Thank's guys,
I wasn't fishing for compliments I promise!
I should replace "talent" with "experience" I have a hard time
getting the paint to lay down smooth without orange peel.
I think proper spray gun setup comes with years of painting and
experimenting with setups.

RE: Kelly's Brio build and pictures
Started work on the wing covering. I will be using Ultracote in
white, orange and black. The white and orange are a little
translucent and one of the main wings had dark spots on the
balsa sheeting. I decided to give the top side of the wings a
couple of light coats of white primer even though it would add
a little weight. I added filler and sanded with 220, primed,
sanded again and then sanded with 320 grit.

Thanks Guys,
DD you might as well sell that P47 and step all the way
into the dark side!
Mike Hester has a sweet plane to replace it.
