Su-30MK (No:603) in 1/72 scale - Heller Su-27UB based

[Serkan Sen 273]

Here is another Flanker project I have launched recently. If you follow my other topics that I have started in this forum, you may ask why I am launching a new one before completing existing ones. Each of these projects has some specific issues to be solved to continue (mostly based on casted parts with aged bleeding resin which was my fault not to check it's shelf life) and therefore they have to wait until the problem does not exist anymore. I hope it will not last too long

 

Here the aim is to build Su-30MK No:603 using Heller Su-27UB kit with minimum modifications (we will see  )

 

I have already made 3 view drawings of Su-30MK No:603 as given below:

 

The next step will be to map camo onto model.

Hi Serkan, I hope your resin pb will be resolved quickly...This SU-30 Number 603 is very nice-> Like this CAMO.

Thanks Neffan, I hope too. Otherwise I might have to cast them with new resin again which is too much work.

[Serkan Sen 273]

I have started with upper half build:

 

and then the lower half:

 

Using magic tape I have put upper and lower halves as well as the nose cone together. After then I have taped the camouflage patterns onto aircraft:

 

As you can see from above pictures the camo patterns fit well at relatively flat surfaces like wings and fins but some modifications are necessary at curved areas like nose and spine.

 

The next step will be preparation of painting masks...

I have placed all modified camo patterns on a blank paper and then scanned it. I have redrawn all modified polylines and vectorised them to be able to cut with plotter/cutter on Orafoil masking paper.

 

Then I placed masks onto aircraft to make final fit check:

 

The masks seem very good with sharp corners as desired.

 

The next step will be adding IFR probe and lights as well as shifting IR sensor to the right side...

 

Serkan

 

[Serkan Sen 273]

Both building IFR probe&lights and IR sensor from scratch is too much effort. I have decided to implant them from nose section of my ongoing T-10M project:

 

After carefully removing both IFR and IR details from resin casting nose part and opening a proper area in kit nose the implant has been placed successfully:

 

Using super glue and and putty the the implant has been done:

 

And adding IFR lights the nose modification has been completed.

 

The next step is to modify cockpit area

[Serkan Sen 273]

The frames surrounding the cockpit area was too wide compared to Trumpeter and Zvezda Flankers (lower picture). This has been corrected as shown below (upper picture):

 

Also the cockpit panels have been redrawn for Su-30MK:

 

Next step will be the final touches before priming the aircraft.

Another great project - looking good so far!

Thanks Andre,

 

As I have "cloned" Zvezda Su-27UB fins, I have decided to use them hence they are better than Heller fins.

 

But this replacement requires removal of fin roots from fuselage aft area as well as HTP actuator part.

 

The kit nozzles and engine upper contour seem a bit unrealistic. Therefore I have decided to use Revell/Zvezda Su-27 nozzle parts.

 

But Heller nozzles are a bit undersized. Therefore as the next step the engine cowling area must be modified to fit Revell/Zvezda nozzle parts.

 

Serkan

 

[Serkan Sen 273]

The next modification is on engine area. The shape of engine cowling as well as the nozzles has to be improved. The upper side needs some touches to correct the engine contour as seen in my previous post above. Here is the close view:

 

The lower side seems not so bad but still has to be modified to fit Zvezda/Revell nozzle.

 

The first step is to  remove  nozzle rings:

 

Here are the replacement parts from Zvezda/Revell kit:

 

The slots have been opened on both upper and lower surfaces to match the replacement parts diameter. Here are the modification steps from  upper left to bottom right:

 

I have also removed wing tip launchers and replaced nose cone with Zvezda/Revell one:

 

The next steps will be:

+ to fill all the gaps and opened slots with putty

+ to add launchers, MLG uplock fairings and ventral fins from Zvezda/Revell kit

+ to coat the model with primer

Serkan,

603 didn't have the standard Su-30 cockpit, it was basic Su-27UB with a large monitor added to the rear cockpit.

Here's my 1/48 attempt from years ago(currently being restored) and the real one below.

Thanks for valuable feedback Paul. I should have had to check the reference books before spending time to modify instrument panels but I can use them for my other Su-30M derivatives.

 

By the way did you finish your marvellous T-10M1 build?

 

Serkan

 

[paulsbrown 619]

Yes, I don't think you'll have any problems fitting in new instrument panels in such a large cockpit.

Yes I did.  I'm glad I finally finished it as it's one of my all time favorite schemes. I'm currently building it's US analog.

My apologies for missing your post. These builds are awesome (background as well)!.. I am afraid my finished 1:72 T-10Ms won't look as beautiful as yours.

Nice work! Very clever approach to the masking.

[Serkan Sen 273]

Here are some more progress:

 

Before applying primer coat I have replaced Heller nose cone, MLG uplock fairings and wing tip missile launchers with Revell/Zvezsda parts:

 

And here are all the parts with primer applied:

 

And close view to nose area shows added IRS and IFR lights:

 

The port and starboard side views:

 

The old and new IRS together:

 

And the removed mid one:

 

Now the windshield has to be polished and front/aft instrument panels' upper pads will be painted to black (as far as I see from reference pictures) before placing canopy parts for final painting.

[Serkan Sen 273]

I was not very happy with the original instrument panel upper pad. Therefore I decided to adopt this part from my T-10M family conversion project based on Zvezda/Revell Su-27SM. Here is the comparison of both parts:

 

Here is the removed upper pad from resin part:

 

Below pictures show the replacement process:

 

The result seems not bad at all:

 

The next step is to apply first primer to modified area and then coat with black both front and rear instrument panel upper pads...

Great work!

[Serkan Sen 273]

Now all modified areas have been coated with primer:

 

And close view of cockpit area:

 

The clear parts have been dipped into Future/Pledge:

 

The front and rear instrument panel pads were painted to black and the canopy parts have been masked with Oramask film:

 

And coated with primer:

 

The next step is to place cockpit parts and apply camouflage colours.
