This time a very simple one. Quick design and build to keep my mind off when I needed a break from other builds (not sure if that makes sense! :) ).
So, 3 views, plan drawing done in a day and will be semi scale, but I think it does look the part. To me anyway :)
WS is 1.4m
So, started with a bunch of parts. Fuselage goes first with the sides in 3mm balsa, 5x5mm balsa in the corners.. Classic! Sheeting will be also in 3mm balsa.

Top of the fuselage is dead flat, so it can be build on its back. Make sure the fuselage does not look like a banana!
The front was more work as there is a quite sharpish bend. As usual, notches on the 5x5mm and where the bends are does help! This is the "hardest" bit on the fuselage build, so not too bad ;D
And we can have a look at the overall shape with a beer in hand! Rudder etc are made of 5mm balsa.

After that, started on the canopy. Executive decision time! Made it removable and in balsa.
Original plan was to make a mold and do it in plastic. Access to radio via an opening under the cockpit floor. But was easier that way. Down side, I lose my cool instrument panel :(

Looking forward to seeing it fly.

It's only a rectangular box with wings really, nothing fancy. But I like the shape I have to say :)

You've clearly gone mad building this. I have to google a Shrike but I have a mental picture of a slightly faster and fatter version of a Shorts 330 but without the fun of a ramp to maybe drop stuff!!!!!!! :)
OOhhh, I like the Short 330! A bit like the slim brother of the Skyvan! :)
Laurent from the Jivaro sells a plan for it. Was very tempted at the time. Unusual model.

I picked another subject :)
Bob Hoover was the obvious choice of course. SO I went for something else ::) Wanted something dead easy to do ;)

It will be sanded with the rest of the fuselage. That hide the radio and it is removable for access to plug stuff.
Need 2 pilots to be glued on the canopy floor now!
Then, attention is turning to the wings! Simple platform, so quick and easy job.
The spars are 10x5mm and are put on a 2mm strip to compensate for the sheeting. As usual, built inverted.
The first rib includes the diedhral, and without forgetting to build the servo frame, the build moves very quickly.
TE is from stock. Simple.

Wings are sheeted in 2mm balsa. TE is made of a 5x5mm square strip as usual.
Wing joiner tubes are glued in place, and servo cable puts in.
Basic stuff.
I then used the 10x5mm leftovers from the spars to glue at the TE. just to give some "meat" when I do the covering as I will use the covering as hinge as per my habits, so again, nothing special here :)
Wing tips are a mix of 3mm plywood and 2x4mm balsa. All that will be sanded in shape later
Ailerons are made with the stock TE.
Next, the engine pods :)

I was not too sure how to make them, but luckily, they are simple.
So like the fuselage, it will be a box :)
The sides are made of 4mm balsa. 2 formers are here to give the usual rigidity. Now, there is a left and right side!
The wing profile is cut on the sides and match where that goes on the wings.
Sheeting is made of 3mm balsa.
For the top, to reproduce the effect of the real one, 2 4x4mm balsa strips are bent/glued on top the wing from the LET to TE of the nacelles. This is then sheeted in 3mm balsa, sanded then covered :)
Proud of myself moment, as it's easy and does look the part.

you can start on the Nimbus next!!
Only joking.
Chat tomorrow or sun morn??

Simple in a way that they are cut in 5mm balsa.
The Shrike have angled elevator (about 7 degrees if I remember). So to reproduce that, I created a flat bit, that goes on the fuselage, and 2 "tail joiners" at the correct angle.
They are glued into notches cut in the balsa. Simple.
I used 2mm Robart hinges, installed with the nice Robart drilling jig that everyone should have!
You can make the back removable if you glue 5mm diametre tubes and use bent piano wires.
The elevator will be moved by a Y. Servo is located under the canopy

Covering done.
Subject chosen
Now, time to piece everything together so we have what's look like a plane :)
First, the subject. It is an Aero Commander 500 from a company called "Pan Adrian" in Croatia. Now the national company I believe.
It was between this one, or one from the Argentinian Air Force.
Anyway, that one did fit the bill in simplicity for a quick job :)
So, all covered in white film. Rudder in Red vinyl. Once fuselage covered, the root ribs are glued and edges covered to hide the wood. At this stage, the wing joiner tube are glued also.
Then, vinyl is cut :) And applied following the photos.
I added my panel lines using my usual 1mm vinyl tape. Less is more, and it does enhance the plane big time. Small things... :)

For the transparent "glass", good tip is to use laminating film sheets. Comes in all sizes. A5 cost 1.99 for 10 at my local supply store. They also do them in A3 for 2 quids more...
So, templates cut, plastic cut then glued. A white vinyl trim finishes it off.
They look happy, so we call it job well done :)
Post by: Fred on June 22, 2020, 09:55:03 AM
Printer to the rescue :)
4 printed (2 spares) and glued straight away to achieve the look.
Post by: Fred on June 22, 2020, 10:00:13 AM
Left to do:
Ailerons servos linkage
CofG
Trow it off a slope
Have a beer (to celebrate of forget :) )
All in all, very simple to build. Very quick (that thing can be done in less than a week I'd say) and plus, I like the look!
I thought I did the fuselage too fat, but, overall, does look right I think.
Only a couple of things to modify on the plan, so not a huge amount of work to finish it off completely.
Hopefully, first flights will tell if that was a good choice of plane... or not!
On a side note, I know nothing in electrics, but seeing it, that would be easy to put 2 electric motors in that thing for an unusual (rare) subject on the flying fields

Very happy, 2 clicks of up, and off it went. With very little wind, was only planning for a straight line and land to check the trims, but that thing went up without any fuss :)
Looks good! More of it later hopefully
