haneto Posted December 30, 2016 Share Posted December 30, 2016 Hi guys After about 4 years no finishing a kit, finally found something attractive enough for me to start with. Yes it's the new ICM 1/48 MiG-25RBT, my favourite MiG-25 variant rather than the interceptor type. And what's more awesome is that ICM even chose my most favourite RBT scheme, the very famous and honored 47th GRAP "Red 46" which is very famous for her nice performance during Chechen–Russian conflict in 2001. Simply cannot resist the "Hero of Soviet" mark and the colourful communist badges! As being said for the error ICM made unfortnately in the kit, is that the nose cone is actually an early RB but not the RBT, I started with the nose correction. Please be noticed that not ONLY the bulge you need to add, but also you need to flat the right side light panel to smooth, then add some panel lines with rivets. Pictures could tell more easily: After several rounds of reshape/sanding, scribe the panel lines then spray the surfacer for check. To be honest I'm still not satisfied enough about the result since the bulge seems too narrow. But since it's underneath, I chose to live with it somehow. 8 Link to comment Share on other sites More sharing options...
haneto Posted December 30, 2016 Author Share Posted December 30, 2016 I also finished piping the landing gears with adding some more details. The ICM kit is genrally OK for the overall shape, but lacks many details here and there. Nose gear. To be continued... 13 Link to comment Share on other sites More sharing options...
exdraken Posted December 30, 2016 Share Posted December 30, 2016 Another one of your masterpieces in the works! Started mine yesterday to do a very early one from 1971.... will watch yours closely Link to comment Share on other sites More sharing options...
IPMS19 Posted December 30, 2016 Share Posted December 30, 2016 - Superb landing gear, which stuff did you use for your nose bulge ? It looks like pieces of evergreen Link to comment Share on other sites More sharing options...
loloskymaster Posted December 30, 2016 Share Posted December 30, 2016 Nice! These landing gears are greatly improved! Great for the noze bulge too. There is only this bulge on RBT, right? I am not sur to make mine RB or RBT... Regards, Lolo Link to comment Share on other sites More sharing options...
general melchett Posted December 31, 2016 Share Posted December 31, 2016 Good start Haneto...I did wonder about the nose profile and it was only after looking at a few images realized that the bulge was missing. Look forward to progress, hopefully start mine once the nose has been sorted out. The exhaust nozzles could do with a bit more refining too but overall a great looking kit.

modelling minion Posted January 2, 2017 Share Posted January 2, 2017 A great start. Really good job on re-profiling the nose, looks very convincing indeed. You've done a very good job on the undercarriage as well, very realistic. Craig. Link to comment Share on other sites More sharing options...

Actually after carful study, it's much easier to convert it to an early R than a late RBT. On 2016年12月30日 at 8:50 PM, IPMS19 said: - Superb landing gear, which stuff did you use for your nose bulge ?

Regards, Lolo The bulge is also on some late RBs so it really depends on the particular airframe you would like to build. Any way, better to study the real aircraft photos ahead.

Thank you for the encouragement. Yes indeed. ICM simpified too much detail on this kit which is a shame, as you can see from the landing gears. It's a bit over for me that there's even not a single rivet on thoese nozzle padels! Yufei Here comes some new progress. Many guys have mentioned that the nosecone and front fuselage fitting is not nice enough which leaves you a big gap or step to sand off. But I would recommend you to dry fit firstly so that you can easily find the problem. 1. The nosecone inner plastic is too thick which bother the fuselage insert properly. 2. The camera bay part also need some edge sanding to prevent the step between nosecone which cause unnecessary sanding work. For 1, just sand off some plastic inside the nosecone where glued by fuselage. For 2, use electric work tape as guide, to sand off the edge a little.

haneto Posted January 27, 2017 Author Share Posted January 27, 2017 Also found some information about the nose, again, that the middile section diameter is not big enough which caused the nose looks straight but actually there should be a gentle curve(yes very gentle, even not noticable if not told). Since it's too late to cut off the section to make such big surgery now after burge is added, I chose to add some material on the top of nose to catch the correct side view look of the nose. This is how it looks like after reshaping sanding: Surfaced. The culve is not so obvious actually from side view. Also scrathc built the antennas for a standard late type RBT nose: The nose shape matches perfect with the plan. Well maybe the plan is inaccurate but at lease both side view and top view spot on, which indicates the original ICM nose shape, at least th side view, is incorrect: Link to comment Share on other sites More sharing options...
haneto Posted January 27, 2017 Author Share Posted January 27, 2017 Another serious question for ICM kit, after a close study, is the wrong shaped intake. The original intake has the curve on top, as ICM designed: But the late enlarged RB intake top is almost straight: It cost me several weekends to correct this. The most time was spent on parts dry fitting and here is the result. Still some panel lines and rivets to be added since ICM also made some errors for them. (Yes as you can read I may cast them as a new product for Fairy Hobby.) 2 Link to comment Share on other sites More sharing options...
haneto Posted January 27, 2017 Author Share Posted January 27, 2017 ICM also made mistakes on belly fins. Panel lines are incorrect on right fin. Original: Corrected: Also you need to add the mechanic chut on left fin bottom side: To be continued... And wish you a happy Rooster new year!

exdraken Posted January 27, 2017 Share Posted January 27, 2017 cool update! thanks for your deep insight into the model! there is quite some great knowledge out there! just to that easy to unite! do you happen to know the differences between the nozzle interior? or even better engien differences between the interceptor and the recce version? Yefim Gordons book is only very vage in detail concerning this aspect.... the corrugated shaped do not seem present on long nozzle petal (i.e. R, RB, RBT, RBx Foybats) R-15-300 variant engines.... https://www.flickr.com/photos/multiplyleadership/6852804025/ Link to comment Share on other sites More sharing options...
general melchett Posted January 27, 2017 Share Posted January 27, 2017 Happy New Year Yufei...I'm surprised at the number of errors to be honest, good spot on the intake shapes. Also if you look at the two vertical panel lines running down the intake side it would seem that the duct (fairing) has been shortened on the RBM as well...may be easier to opt for an earlier RB...
