North American Harvard IIa

Recommended Posts

I'm currently building KH's Texan as a Harvard IIa of the Rhodesian Air Training Group, specifically Harvard EX490 which was based at 20 SFTS Cranborne in 1943/4.  My reasons for choosing this particular aircraft are very simple: a) it was flown by my father during his pilot training days:

and B) there's an excellent colour photograph of it in the IWM collection:

My intention is to show the detail that KH have put into the engine area by cutting off the nose panels and not fitting some of the cowling though the "plumbing" both electrical and hydraulic will be a best guess based on the sources that I currently have, so therefore not 100% accurate by any means!  

 

To try to make it as correct as I feel inclined to (and I know this is a potential minefield), I have the AlleyCat canopy (which I've reviewed on this site), AMS Resin's 9' prop blades, Scale Aircraft Conversions whitemetal landing gear (though I think KH's is OK (?), and Airscales WW2 RAF instrument dial decals ready for the corrected instrument panel that I'm making:

When finished it'll be displayed as a small diorama with this chap sitting waiting for the repairs to be done:

More later on the build :)

I started with the P&W engine, I found the whole assembly quite tricky to get my head around, with many senior moments happening but I knew from Kev's experience with his test build that it had to go together with everything orientated properly.  The kit has been criticised rightly for the moulding marks and gates etc., those on the engine halves are especially horrible:

A while cleaning up, including cutting off location pins (which I've done a lot of with this kit) and the halves fitted well enough.  I had already decided that KH's moulding of the plugs and plug leads wasn't good enough:

so those came off to be replaced by plugs of stretched sprue and wire leads:

The backing plate for the engine only fits one way to allow for the oil tank sump to be at 6 o'clock, care also needs to be taken to ensure that the con rod guides align properly with the cylinder heads, it's easy to get them wrong!:

 

 

 

Fitting the exhaust collector ring and its cover etc had me scratching my head, again correct orientation?!  Another place where, once I'd decided what was where, to cut off location pins which I find helps me locate things more easily:

Finally the engine assembly was completed but not without a lot of thought and dry fitting:

Time to move on to the cockpit next.

Thank you for your kind feedback chaps! :)

 

The cockpit framework was another area that I took my time over, it needed careful thought because the instructions can be quite confusing, including the typo for item "E51" in step 3, half of a fire extinguisher which mates with B12 - the item is actually E15.  I'm not sure about the curious semi-circular item behind the aft cockpit (item D31), I think it's related to the blind-flying hood so I'm probably going to add the hood at a later date.  The whole structure I thought was well engineered and fitted together very well but it's worth checking that all the location holes on the side structures are drilled all the way through before final assembly:

I added the Eduard seat belts since the KH ones were a little basic.

Very nice work.... everytime I see one of these birds I am reminded of my flight school days as the field I learned to fly at had a few of these Harvards sitting around.... I think there was even a chipmunk too...

A classic trainer that was purposefully built!
Cheers

.... might get this kit too!!

I've added the internal ribbing detail with micro-strip - with the canopy as open as I want it to be I think cockpit detail is essential.

I must admit that I'm impressed with the precise fit of all the parts, so far very little fettling has been required.  I'm starting to add some wiring etc on the firewall and added some brackets for the battery.

This shot illustrates how the front compartment has been opened up by removal of the side and top panels and gives some idea of the space to be filled with cabling, hydraulic lines, engine support bearers etc.

I'm certainly enjoying the build of my first LSP so far!
