Marklo Posted February 12, 2020 Share Posted February 12, 2020 (edited) I see you like my avatar. Poor Pip died last year but he did live to 22 and had quite the life. I had him from a kitten when he and his mother turned up in my garden. She became our pet once we had tamed her.

Serkan Sen Posted February 12, 2020 Author Share Posted February 12, 2020 The drone carrier was slightly modified at the rear end: All drone related parts were coated with primer: The fuselage halves as well: Now everything seems fine: Serkan 12 Link to comment Share on other sites More sharing options...
Planebuilder62 Posted February 12, 2020 Share Posted February 12, 2020 Dear Serkan The air data probes on the D-21 drone were only fitted when the drone was air launched from B-52’s. The few pictures of the M21 and D21 combination show no probes. The D21 intake lip needs building up with super glue after the top and bottom go together and should be filed to a sharp edge.

Regards Toby Hi Toby, Thanks for pointing this important detail. I will do all these changes during drone detailing. I will add both nose and tail cones in my build.

March Posted February 12, 2020 Share Posted February 12, 2020 I’ll tag along for this one. FWIW, I’ll be coming face to face with the M21 in real life this August as I’m heading out to Seattle to visit a dear friend who used to be heavily involved in the aviation industry. His company also built the stands and recreated the rail the D21 sits on on the M21 airframe as part of getting the airframe ready for exhibiting at the Museum of Flight. He’s crawled all over that bird and sat in the pilots seat. Envy is not the word... 3 Link to comment Share on other sites More sharing options...
Serkan Sen Posted February 13, 2020 Author Share Posted February 13, 2020 (edited) Here are the reference photos I found on web for D21 nose and tail cones: Based on above pictures I did below drawing to visualize side and top views of drone with covers: The panel lines in above drawing is most probably not fully correct but my aim was to see how D-21 looks like with covers. Also I will use it to shape these parts. Serkan Edited February 14, 2020 by Serkan Sen 5 Link to comment Share on other sites More sharing options...
Serkan Sen Posted February 13, 2020 Author Share Posted February 13, 2020 (edited) I have started first scribing the Tagboard panel lines. To position the steel ruler on model surface I have used double sided tailor tape: Before placing it on painted kit surface it is better to stick it to hand to make tape less tacky. The good part is the tape is very cheap compared to Dymo tape. But for highly curved or cylindrical surfaces Dyma tape is still the best solution. Now I am ready to scribe the panel lines. I have sanded the primed surface very lightly down to remove raised panel lines and use their traces for scribing. The kit surface quality is very poor probably releasing the injected part before enough cooling, but this is not a problem for this build, because all the panel lines will be scribed and the surface will be sanded with fine grit paper (1000-1500).

billn53 Posted February 13, 2020 Share Posted February 13, 2020 Thanks for showing your scribing technique, that’s one thing I’m terrible at. Using double-sided tape on your guide is a great idea. 1 1 Link to comment Share on other sites More sharing options...
Nikolay Polyakov Posted February 13, 2020 Share Posted February 13, 2020 I was out of the forum for a while and skipped a lot - you’re going fast, Serkan! Really fast. And it’s a pleasure to read all these stories here. 🙂 More cats, please! 😻 15 hours ago, March said: He’s crawled all over that bird and sat in the pilots seat. Envy is not the word...

Serkan Sen Posted February 14, 2020 Author Share Posted February 14, 2020 To build nose and tail cones I have found two donors from spare parts box: To build nose cone I have used an old F-101 fuel tank, and for tail cone a F-4 fuel tank (most probably more than 40 years old): The result looks pretty good: Next is to finalise tail cone details.

Serkan Sen Posted February 15, 2020 Author Share Posted February 15, 2020 All the panel lines of lower and upper halves were scribed with the same method used for drone: Next step will be adding front and rear cockpit details and glue both halves together. The front cockpit was already modified in Part1. The similar modification will be done for rear cockpit as well. Serkan 15 Link to comment Share on other sites More sharing options...

Especially scribing all triangle panels on both upper and lower surfaces leading and trailing edges is really time consuming. 3 Link to comment Share on other sites More sharing options...

It would be nice if you’re casted the cones as a separate parts - to have an option for display D-21 in operating configuration. 1 1 Link to comment Share on other sites More sharing options...
Serkan Sen Posted February 17, 2020 Author Share Posted February 17, 2020 Thanks Nikolay. Yes I have made the parts separately to be able to cast them. I have already coated the drone and cones with primer and tomorrow I can share some photos. I have 4 drones left from various projects. Displaying drones with and without cones won't be a problem 😁 Serkan 3 Link to comment Share on other sites More sharing options...
Serkan Sen Posted February 19, 2020 Author Share Posted February 19, 2020 (edited) The Tagboard was coated with primer: The mothership and drone with cones looks very nice: The kit cockpit parts were also coated with primer and painted in black. Today I will complete cockpit details and glue the fuselage halves together. Serkan Edited February 19, 2020 by Serkan Sen 14 Link to comment Share on other sites More sharing options...
Serkan Sen Posted February 22, 2020 Author Share Posted February 22, 2020 The rudder panel lines were scribed and the surface was sanded down to remove casting imperfections: During A-12 build I didn't noticed that the nose wheel bay was overlapping with original kit cockpit tub. Therefore the rear part of kit cockpit tub was shortened around 5mm. Also the front part was slightly sanded and tapered to fit lower surface: And finally both halves were glued together: Next will be adding nose cone and filling all the gaps.

Serkan Sen Posted February 22, 2020 Author Share Posted February 22, 2020 (edited) The nose cone was glued to its position and all gaps were filled with putty: Note that before using putty the lower surface seam line was masked with vinyl masking film strips and then filled with Revell putty. After approximately 30 minutes the putty mask was removed and the seam line was very clean even before sanding with 800 grit paper. This is the method I always use for all seam line and gaps before filling with putty to reduce sanding effort and prevent surface details.
