Serkan Sen Posted August 6, 2018 Share Posted August 6, 2018 (edited) As I was looking around to find some reference pictures for one of my ongoing projects namely Su-27M (T-10M 701, 703, 709 and 711) I have landed the Ken's Su-27IB conversion progress page. Then I decided to launch a parallel project for T-10V1 conversion using one of my Revell Su-27SM (I have 60+ pieces of it 🙂) and Italeri Su-34 (currently only 4 pieces in hand) kits. The main idea is to join Su-34 nose and Su-27 rest. Next I will add some pictures of my work in progress.

Serkan Sen Posted August 6, 2018 Author Share Posted August 6, 2018 (edited) Here are the upper surfaces of Su-27 and Su-34 kits... The green line is the cut line for Su-34. And these are the lower parts of both kits... The dashed lines show approximate cut lines. I have started this conversion first by removing the front fuselage part of Su-34 kit. The spine of Su-34 is obviously wider and higher than Su-27 one. With a little surgery this can be easily fixed. Now the planform seems ok,.. but the side view not yet!.. The first fit test of Su-34 front fuselage to Su-27 rear part... Now it is time to correct spine shape... And here is the finished shape. Many other Su-27 parts have been also attached to check part fits. Please note that the slat root slots have been also opened in Su-34 front fuselage part. The bird seems to appear slowly 🙂 And the bottom view... The main wheel bays are needed to be taken from Su-27 kit with a little surgery as well as the cannon details... The more pictures will be later... Edited September 9, 2019 by Serkan Sen Picture links have been updated 6 3 Link to comment Share on other sites More sharing options...

Serkan Sen Posted August 7, 2018 Author Share Posted August 7, 2018 (edited) Thanks lot Vultures1. I think Revell/Zvezda kit is very well detailed and easy to modify. I have several Heller Su-27UB kits but the surface detail is not as good as Revell/Zvezda has. Yes I fully agree Ken. This will be a bit challenging to modify intakes. Returning back to progress, the areas to be improved in front fuselage upper half are; Wing root/front fuselage intersection including MLG Bay details. Wing LERX. Canard fuselage connection with fillet. Cannon details Straight-edged fillet added to the chine to be removed/rounded. First starting with cannon... With a small surgery I have removed the cannon area from Su-27 donor and transplanted to Su-34. and a bit putty and support to heal the wounds... Now the cannon area seems better... The next implant is the MLG Bay and LERX areas. Here are the cut lines from top view... And MLG Bay details from bottom... Su-34 front fuselage before modification: ... and after modification: Now the modifications 1, 2 and 4 listed above were completed. The canard root fillet and removal of straight edged fillet to chine modifications will be done after lower part modifications. The more pictures will be posted soon.

Serkan Sen Posted August 9, 2018 Author Share Posted August 9, 2018 (edited) Next step is to modify Su-34 front fuselage lower surface. I started first removing nose section of Su-27 from the rest. and here is the cut line for Su-34 lower part: The Su-27 air intake splitter plate stands will be added to Su-34 part... One side has been already glued... And as usual part fit check after modification: Top view... and bottom view... Hence the upper and lower Su-34 nose parts are now together, I can remove straight edge fillet added to the chine. Please note that I have replaced Su-34 rear spine with Su-27 one to have perfect fit to rear fuselage part. The next modification is to add fillet to canard root area on fuselage fairing... done... Also I am not happy with drag chute door in Su-34 (as I did significant sanding and grinding at that area). Su-27 donor part helped me to improve this... Next step will be modifications of VTPs (Su-27 to Su-27UB) ...

Serkan Sen Posted August 12, 2018 Author Share Posted August 12, 2018 (edited) Here is the comparison of Revell/Zvezda Su-27, Italeri Su-34 and Heller Su-27UB fins: Italeri Su-34 fin has reasonably good size but the rudder shape is not correct. Su-27 fin has to be extended to Su-27UB size... The shape can be corrected by inserting plastic cards... Performing the similar modification on the right fin: The result is not so bad The next step will be the intakes...

Serkan Sen Posted December 9, 2018 Author Share Posted December 9, 2018 Last few months I was a bit busy designing a web page (I have uploaded my all work on progress pictures to my web site and linked directly from there) and some house renovation tasks assigned by my wife to me... After a long break, here are some progress on intake modification. As first attempt, I have started to modify Su-27 intake. and the result is seen as below: From the reference pictures the shape of diverter of Su-27IB seems a bit different than Su-27. With my best guess it should look like this: After modification the new diverters are now as shown below: 5 1 Link to comment Share on other sites More sharing options...
Serkan Sen Posted December 9, 2018 Author Share Posted December 9, 2018 Although the intakes look not so bad, still I was not very happy with the result. As a solution I have decided to use Trumpeter's Su-34 intakes. The comparison of modified Su-27 and Trumpeter Su-34 is given below: As the Trumpeter Su-34 kit is too expensive to use it's parts as donor, I have decided to "clone" the intake parts: Only some parts of Su-34 intake is needed to convert Su-27 into SU-27IB one: Now the result seems better than my first attempt: Adding the splitter plates: The next step will be the nose landing gear bay modification... 6 2 Link to comment Share on other sites More sharing options...
mirageiv Posted December 10, 2018 Share Posted December 10, 2018 (edited) Brilliant work Serkan! I'm really impressed in particular by how you have aligned and blended all of the replaced parts so well, especially given the amount of modification, 10/10. Rather difficult and you have made it look easy. I look forward to more. Cheers, David Edited December 10, 2018 by mirageiv 1 1 Link to comment Share on other sites More sharing options...
Serkan Sen Posted December 11, 2018 Author Share Posted December 11, 2018 (edited) Hello David, Thanks for your kind and encouraging words. I am very close to finish this project. I have also had a look your ongoing Viper projects. I have 4 Vipers (all in 1:48 scale and one of them is the Skunkwork/Kinetic F-16XL Ship 2 "double seater") waiting on bench to be completed. Today I am lying in bed due to heavy flu. Hopefully I can post new progress pictures in the following days of this week. I can share today only 3 view drawings/artwork I finished last month. Any comments/improvement proposals are welcome. I know that the camo edges should be transient but it is really big amount of work to do in vector graphics.

Serkan Sen Posted December 14, 2018 Author Share Posted December 14, 2018 (edited) Here are the next modifications in NLGB area; First the comparison of Trumpeter and Italeri kits... Again I have cloned Trumpeter NLGB... The nose landing gear assembly is also very poor in Italeri. It will be "cloned" from Trumpeter as well...

Serkan Sen Posted December 14, 2018 Author Share Posted December 14, 2018 (edited) The cockpit of Italeri kit is not well detailed. Therefore I have decided to use "Pavla" Su-34 resin detail set (C72006) to improve this area: Now it looks much better 🙂 Here is the comparison of Trumpeter NLG assembly versus Italeri: and close view to Trumpeter one: when assembled to kit, it looks much better than before modification: The wheels and mud guard will be used from Armory Wheels (ARW72035) resin parts...

Courageous Posted December 14, 2018 Share Posted December 14, 2018 I know next to nothing about these aircraft types but the work you're putting into this is truly impressive. Stuart 1 Link to comment Share on other sites More sharing options...
Serkan Sen Posted December 17, 2018 Author Share Posted December 17, 2018 (edited) Thanks for your kind words Stuart. I was waiting for Zvezda's new SU-27UB kit for Su-35UB conversion and finally this kit has been released. I have ordered three kits and they have newly arrived. Impatiently I have started the kit conversion which I report here. The kit has very nicely detailed vertical fins and early slats (left and rightmost parts shown below) which are needed for Su-27IB conversion: Also I have "cloned" canards from Revell/Zvezda Su-33 kit: The next step will be the final fit test before gluing the parts together...

Serkan Sen Posted December 17, 2018 Author Share Posted December 17, 2018 Hi again, Here are the final fit test shots. The model seems now complete: The next step will be painting.

Serkan Sen Posted April 5, 2019 Author Share Posted April 5, 2019 During last several weeks I have received many private messages asking about the availability of modified parts of this Su-27IB kit-bashing. Then I decided to make molds to duplicate the parts. First I have started to divide the upper front half into two pieces to make molding easier: Then I have prepared the outer skin molds of fuselage halves: And similarly the inner mold halves: Now the molds are ready for test casting: The results seem not so bad 🙂 The next step will be the canopy/windshield and engine inlet moldings which will be a bit challenging... 👷♂️ Cheers Serkan 5 3 Link to comment Share on other sites More sharing options...

Serkan Sen Posted September 8, 2019 Author Share Posted September 8, 2019 After a very long break on this project here I am back with major progress. Hence I need several copies of the canopy I need to clone the clear parts. The original canopy has been used as master form and this silicone mold was prepared: Using UV resistant crystal clear epoxy resin I have casted the part: The result is not so bad. Here above right to left: original canopy, casted with PUR and with clear epoxy respectively. The next step is to clone NLG bay doors and strut from Trumpy Su-34.

Can you elaborate on your process and materials? It appears you have a 2-part silicone mold, I'm curious what clear resin product you're using and whether you're using a pressure chamber or other methods to get such a pristine part. 1 Link to comment Share on other sites More sharing options...
