MXY7 Ohka Model 11 in 1/72 Scale by Sergio Teixeira

Hard to believe that this stunning model of an Ohka piloted flying bomb was created by Sergio Teixeira from the Hasegawa 1/72 kit included in their G4M2 'Betty' bomber kits. Sergio tells the story of this remarkable transformation.

'The kit I used was from the 1997 Hasegawa CP-8 release, which included the mothership, a G4M2E. The kit itself is very basic and has many shortcomings, needing a lot of work to create a better model. Externally I scribed all panels and added every visible detail

'Internally I added the ribs and frames - from the cockpit to the rear fuselage end, scratchbuilt the cockpit, rocket engines and every visible (and invisible) detail. Then, I replaced the original canopy with a vacuform canopy by Falcon.  I painted it in a 'generic' light grey and added a few decals. Finally, I placed it on a scratchbuilt dolly. That model was made in 1999 with the very little information or images available to me  at that time. 

'A couple of years ago, after seeing pictures of a restored Ohka at IWM, I decided to correct and upgrade the model.  I removed and corrected the nose shape which required a lot of sanding and reinforced it internally with putty, adding some weights in the putty to keep the model nose heavy with intent to place the model on its new dolly. I replaced the old cockpit with new scratchbuilt parts, including the stepped firewall and an armour plate.  Then, I made the bulges under the wing roots with Tamiya epoxy putty, scribed some missing panels and added other details. 

'Finally, I replaced the attachment ring and made new balance weights for the ailerons. I painted it using Mr. Aqueous Hobby H314 Blue FS35622 (wings and tail surfaces) and AK RC303 Amber Grey (fuselage and metal parts) as advised in the Ohka Colours file. Decals and stencils were cannibalized from the Brengun Ohka 11. I did very light washes with Tamiya panel line accent color grey and AK paneliner black to improve its realism. The new dolly is from Brengun too, with some modifications.

'In the end I'm simply in love with the results (me too, Ed), it was worth all the effort to modify and correct an already built tiny model. Thank you so much Nick for AoJ blog, which gives me so much information and inspiration!'
