Always nice to see a big collection of the same plane.

After this Air Canada version, I am building a ComAir one that Gary just repainted per my request.

The topic of aviation always garners strong opinions.

The reality is that most aviation companies make bad decisions or on the occasion of a good decision, it gets screwed up later on ( like the CRJ series and it's Canadian producers ). Most bad decisions are due to politics or trying to get political favors from governments. And when it comes to military planes, you can multiply the screwups by 10.

As for the models, it is good to see different techniques and methods of building. I am sharing mine along with some background.

The CRJ-200 was powered by the Ge CF34-3 engines. Those were derivatives of the TF-34 engine that powered the A-10 and the S-3 planes. The engines are podded and placed on canted pylons to the rear of the plane.

I did not take pics of the building process of the nacelles. My only comment is that there are a few internal parts that are redundant. Otherwise it is straight forward build


Here is the engine nacelle and pylon


and installed on the fuselage.

The CRJ-200 having its engines in the rear dictates that the horizontal fins are placed high above both the engine exhaust as well as prevent it being blanketed by the wings at high angle of attack ( as in take off and landings ). Thus it is located on top of the vertical fin.

The horizontal fins are all moving and the segments that look like separate elevators are for trim and smaller movements and in some cases are elevators. This is common with other planes like the DC-9 etc....


The inventor of the T tail is a German aero engineer Hans Multhopp who pioneered its use on the WW2 jet the TA-183.

The T tail flies on many commercial and military applications like the C-5 Galaxy. It has also been used on general aviation prop planes ( like the Piper Arrow T tail version ), but in my opinion only for esthetic purposes.


Here are the parts



I inserted a small piece of a paper clip for internal support of the horizontal fins

dry fit first



and installed ( the small intake scoop at the base will be added later ).

Once again, it looks like a great fit on the tail sections and the engines. Very nicely done.

It's good that you reinforced the wing root structure Isaac, as the original looks rather flimsy to me. I remember the same from the DC-9 model. While building at the time, Jeremiah sent me an update of the model (with improved skin details, such as rivets) and I partly used the upgrade parts as I was already halfway. Also the inside wing reinforcement had been modified. Where possible I like to internally laminate the wings, to make them stronger, and especially what you've done at the landing gear wells is well thought of.

Horizontal and vertical stabilizers probably require some strengthening too?

I always re enforce all my structures. The tail has wood and metal for additional support as well.

As for the DC-9, I will build the Eastern version soon after I build a newly repainted Mig-17F that Gary did. Then I will continue building another airliner.

Thanks

Here it is so far.





Other than the small antennas and the flap guide covers it would be done. However, I will build the landing gear later on.


Isaac

[Isaac]

The designer provided parts for the landing gear struts and wheels. However, in my opinion very little can be seen and secondly, the parts need re enforcement. So for me it was easier t just discard them and make the struts out of wood dowel and insert paperclip segments at the bend, attachment to the wing support and the axles. Those were painted silver.


Here are the laminated cardstock wheels being painted


and hubs ( not the best of jobs, but really barely seen )


struts



and attached



I also skimped on the nose gear strut details due to the small length exposed.


On gear



At this point added the small blade antennas

At this point, the model is complete and ready for display with my usual background.

It was a fun build! So much so, I asked Gary to repaint it in ComAir colors ( Cincinnati Ohio based airline that was gobbled up by Delta and then "killed off". More on that when I share that build here next.
