K-8 trainer in 1/72 scale using the Trumpeter kit: review and modelling report
In the nineteen nineties both China and Pakistan required a new jet trainer and a joint project was started. The two countries already worked together on aircraft programs before, like license build and adapted MiGs and many more.
The Hongdu JL-8 (Nanchang JL-8), also known as the Karakorum-8, is a two-seat intermediate jet trainer and light attack aircraft designed in the People’s Republic of China by China Nanchang Aircraft Manufacturing Corporation. The primary contractor is the Hongdu Aviation Industry Corporation. One of its export variants, K-8P Karakorum is co-produced by the Pakistan Aeronautical Complex (PAC). The PAC K-8 is called the Karakorum (old capital of Genghis Khan's empire). The JL-8 / K-8 has a multi-role capability for training and, with little modification, can also be used for airfield defense. The aircraft is supposed to be as cost-effective as possible, with a short turn-around time and low maintenance requirements. The JL-8 for the domestic Chinese market and its export variants, K-8E and K-8P, have different powerplants and avionics. Exports of this aircraft ....... were done to Egypt and a dozen other countries..

1/72 scale there is a nice model
from Trumpeter, kit no. 01636 . The kit was
released in 2008.
The K-8 is for western modellers a strange subject and is very welcome that unusual subjects pop up once in a while from Trumpeter. The kit has a about 50 grey parts which are crisp and fine and has nice recessed panellines. The canopy is cristal clear as well. There are a couple of fuel tanks in the kit with a gunpod (which I did not use).
Inside the nose, just add some weight just in case to prevent tail sitting.
- the control sticks (parts B14) fit better when the locating lug is reduced in size;
- add a few pieces of plastic card aft of the intake to suggest "tunnel";
- the "gear down indicators" on top of the wing are nicely done in the kit but I removed them to enable wing-root sanding and replaced them with metal ones.
- the tailplanes dihedral angles as per kit is far too large; trim the locating fairing at front at the fuselage to get only slight dihedral of say 3 degrees.
- the main gear legs fit better when enlarging a bit their locating holes in the bays;
- the nose wheel doors are more easily fitted BEFORE installing the nose gear leg A3;
- the nose pitot B16 is better fitted just before completion;
- the windscreen C1 will fit (may be you need to remove some tiny flash), but some white glue is needed to close the gaps; paint the white glue once dried in the appropriate colours.
basic assembly, a first coat
of light grey was air brushed to check for any flaws. It seemed
It was decided to choose scheme as per kit. Scheme [B] with red-white and blue stripes of Pakistan AF was picked. The colours were applied with the air brush .
First, the overall gloss white colour was airbrushed, after drying areas for the red colours were masked with low tack TAMIYA tape and airbrushed. You have no choice as the red stripes were missing in the decal sheet (the blue is provided as decals). The decals are fine and thin.
The landing gears were installed and painted light grey and tyres tyre-black/grey. with their bays light grey. (the oleos were painted silver) .
Next, additional work on detailing the model:
(1) the clear blast screen in the canopy is missing between front and rear seat; this was made from thin clear sheet and added inside the canopy;
(2) I added 2 mirrors at the front canopy edge and in the back 2 mirrors for the instructor on stacks at that blast screen; mirrors came from a REHEAT mirror etched metal set.
(4) the large pitot tube B16 was fitted; better is to remove the small locating lug and the big pitot should be moved 2 mm more aft for a correct position;
(5) a small extra pitot sensor was added in front of the windscreen amidst the upper anti-glare panel;
(6) the seats got some harness straps made from tape;
(7) at the upper right and lower left tailplane elevator trim tab an actuator rod was added from thin sprue;
(8) the right nose sensor (part 18) on many aircraft is a straight probe (like on the left side);
(9) the gun pod B13 is often seen to be different in shape on real
(10) paint the anti-collision lights at wing tips and top of tail;
(11) static dischargers were added made from thin flexible fishing wire: 2 at the ailerons, 2 at elevator and 1 at rudder tip.
A slight darker wash was applied at the recesses of ailerons and elevator. Finally, the whole model got a sealing Johnson Future coat airbrushed on to it.
The canopy was set open and turned to the right. That competed this nice model of an unusal type.
NOTE: on the Pakistan K-8 model below I did not correct the stabilizer dihedral. This model was made in 2014 and I had not discovered this yet. and... It was pointed out that the nose wheel leg position I had wrongly glued (inverse)!!! Was corrected as well!
Pakistan air force was established in 1947. It was involved in various conflicts with neighbor India and tensions are still there after so many years. It was supported by the USA in those days. In the 1960s jet aircraft like the F-86, F-104 and B-57 played an important role. Also other Western aircraft were purchased like Gnats and Mirage III attack aircraft. The regional wars like in Afghanistan and terrorist threats still plays an unstabilizing role. The K-8 Karakorum was developed with China were it is known as the Hongdu JL-8. Over 60 K-8 trainers are probably used. It is hoped that modern F-16s will be supplied by the USA and the own Pakistan JF-17 Thunder is expected to enter service. Meanwhile many Mirage III/ V are in service along with Chengdu F-7 fighters. Other aircraft are a large variety of transports and trainers like the T-37 and PAC MFI-17 basic trainers and many helicopters.
