FlorinM Posted August 19, 2014 Share Posted August 19, 2014 Once more I serve as middleman between you guys and Lucian and we will witness the creation of yet another replica masterfully done, this time a Frogfoot from Trumpeter. Accessories to be used with this kit come from AIRES - the Zvezda K-36l ejection seat and the exhaust nozzles, from ARMORY - the wheels, from PROFIMODELLER - Pitot tubes, QUICKBOOST - Fan, antennas and air intakes. The decal sheet is The Rook: Global Su-25s Part 2 from LINDEN HILL. Link to comment Share on other sites More sharing options...
FlorinM Posted August 20, 2014 Author Share Posted August 20, 2014 Very few Trumpeter kits in 1:32nd scale do not require surgery. And their Frogfoot is definitely not one of them... What these pictures found on the Net - posted here for discussion purposes - show was confirmed by overlapping the fuselage halves on Russian scale drawings (from Modelist Konstruktor I think) that were enlarged to 1:32nd The kit has length issues, seventeen (17) millimeters have to be added in two sections, 8 mm in the front and 9 to the back. Also the angles on the landing gear are wrong... The red lines represent the places where the cuts will be made. Uncarina and Kagemusha 2 Link to comment Share on other sites More sharing options...
Zero77 Posted August 20, 2014 Share Posted August 20, 2014 Nice ! It will be interesting for sure. However, i think this trumpeter kit is quite good and funny to build. I haven't corrected the shape issues, as in my opinion it didn't worth it (i cant notice any of the shape issues when i look the model with my eyes only). If you need some more AM stuff to ehance the kit, you can also find a very nice brass pitot set on Ebay (from a korean guy, this is a very nice milling job as the small fins are milled in the mass) and the #1 and 10 pylons that are missing in the kit from Zactoman. Here are some pictures : Link to comment Share on other sites More sharing options...
FlorinM Posted August 20, 2014 Author Share Posted August 20, 2014 You are free to do what you want, as long it is fun for you. But a kit is definitely not OK when it is too short by almost 2 centimeters (meaning more than half a meter in real life), the engines are misplaced, the angles on the landing gear are wrong and the whole tail assembly is not where it should be... Speaking for myself, if I know that a certain kit has issues and it is in my ability range to correct its issues I cannot and will not leave it as is. And my friend, the one that builds this scale replica has the same mind frame. Link to comment Share on other sites More sharing options...
dutik Posted August 20, 2014 Share Posted August 20, 2014 Don't know if its a great idea to make a cut at the front. Drawings show good fit of the kit front, while photos of the real thing always have some shape and distortion issues. The lenght issue is towards the rear. Would suggest to make a cut at the line crossind the "Cy-25" name at the drawings; through the rear fuselage and engines and to add a plug there. This could fix the overall lenght, bring the tail, fin and engine exhausts into proper position while saving the wheel wells.

Zero77 Posted August 20, 2014 Share Posted August 20, 2014 (edited) Of course i understand your point of view, and that's a really good thing as you show us great job. I just wanted to say that the kit is not that bad, even if it can be corrected and ehanced in several points. Anyway i'm definitely waiting for your updates !

FlorinM Posted August 20, 2014 Author Share Posted August 20, 2014 @ dutik: The cut at the front is designed to fix the position of the engines, while the one at the rear corrects the empennage issues. It was carefully measured and thought over and over. Link to comment Share on other sites More sharing options...
dutik Posted August 20, 2014 Share Posted August 20, 2014 I understand now. The engine nacelles are longer than the visible contact area at the fuselage side. Go on! Will the front cut affect the undercarriage bay? I. e. do you have to rebuild or relocate them? Oh, and what is the number of the M-Hobby issue with the drawings? - dutik Link to comment Share on other sites More sharing options...
steel_tiger Posted August 20, 2014 Share Posted August 20, 2014 Does this hold true with the SU-25 UB as well? Link to comment Share on other sites More sharing options...
FlorinM Posted August 20, 2014 Author Share Posted August 20, 2014 @dutik In theory the front remains the same, everything gets pushed to the back. In a worst case scenario you'll have to add a rectangle 8 mm long to the rear of the bay. Stay tuned and we'll find out! Don't know about the M-Hobby issue... @ steel_tiger Sadly I cannot answer that, Lucian does not have the twin seater. In theory it should be a different fuselage dutik 1 Link to comment Share on other sites More sharing options...
Radub Posted August 21, 2014 Share Posted August 21, 2014 Hmmm... Trumpeter has a "history" and you may be right, but the "methodology" used here is not very "solid". There are too many "red flags" popping up all over the place. When using photos, there are issues caused by lens distorsion, parallax, focal length, and so on. I would be very mindful about comparing a photo of plastic parts to a photo of the real thing. Also, I would be very careful with scale drawings... Scale drawings can sometimes be wrong. There is one more "test" you must perform: I see that you compared the plastic parts to the drawings and the plastic parts to a photo of the real thing but by any chance did you compare the photo of the real thing with the scale drawings? Also, have you considered the drawings published in the 4+ book? Just in case... Just before you start cutting, "masoara de doua ori si taie o data" (measure twice and cut once). ;-) Radu Link to comment Share on other sites More sharing options...
FlorinM Posted August 21, 2014 Author Share Posted August 21, 2014 The first cut was made and the engine intake lip is now where it should be. Lucian will proceed with the second cut, already marked. Link to comment Share on other sites More sharing options...

harvy5 Posted August 21, 2014 Share Posted August 21, 2014 (edited) Interesting start! I do not know, is a drawing of the M-Hobby correct? It's a copy 4+ and there were inaccuracies. In my opinion the exact drawing is in the publication Sturmovik Su-25 and its modifications by author Ildar Bedretdinov.I'm not saying that I have but right now modify UB version of T, and there I came across a main errors fuselage, only the tail section.

FlorinM Posted August 22, 2014 Author Share Posted August 22, 2014 (edited) The twin seater Su-25 UB and its derivatives have a different front fuselage section, so it is irrelevant for this discussion because Trumpeter had to make another fuselage. The book you mention is very hard to come by. If you have it, could you please scan the line drawings and send them over?
