For some reason after seeing this post I literally went to go microwave a bag of popcorn. |

Hi Madmax, Nice to see a SAAF Sabre in 1/48. I am also in the process of doing a MK-6 and have found some interesting facts about the MK6. I am sure you know most of these but I will list them anyway. The Mk-6 Cockpit was light Gray inside as opposed to the earlier Black.(According to the internet this changed in 1954). The wheel wells and airbrakes were painted dark green as opposed to the earlier Zink Chromate. The Hasegawa kit is basically a F-86 and to do a Mk-6 two vents need to be added to the fuselage side as well as two new panels on each side and a filler cap panel on the right hand side. The sugar scoop intakes in the lower fuselage was also fitted to the Canadian manufactured Sabres. The wing of the Revell/Monogram kit is a small wing so the slats need to be grafted onto the Hasegawa wing. Unfortunately it is not just a simple wing swap.(Or you can cut and extend the Revell wing but then the piece below the fuselage needs to be swapped as well.) Interestingly the sweep angle on the trailing edge of the two kits are different. I have not found out which is correct. I see on the decals there are two sizes of castles. I was under the impression that the Sabre only carried 24-inch castles. Looking forward to this build. Regards Joker |

That F-86D kit is way too nice to chop up. I think you should scratch build the slats and cast resin pieces!! And then sell the masters to John at Scaleworx..... . Anyway, looking forward to this one. I've never really had the desire to build a Sabre so hopefully you'll pique my interest ! |

Thanks for your show of interest gents! Most amusing MARS, we really do need a popcorn-man please Dean. Joker, I concur with all your points of research. You do know a lot of stuff. I'm willing to bet your Sabre will have a blue fuselage band . Malcolm, it does seem a waste. I justify it with the potential use of the tractor. Want the fuselage? |

No popcorn man, but I do have this one on page 4 of the Smilie list |

So, how to get slats onto the wing? Initially it seemed as if a resin leading edge and slat replacement was the way to go. Unfortunately these are no longer readily available - as with many old models, they go out of fashion. For the uninitiated, I must mention that Sabres had many different wings. Much like Spitfires. You can look this up yourself. The Sabre in question is the one the SAAF bought from Canadair, a CL-13B Mk.6. This Sabre has a broad chord 6-3 wing with slats. Hasegawa were having none of it, and went for a 6-3 "hard wing" on their Mk 5 kit - simple moulding. When they offered the Mk.6 they went for a North American wing, the F-86F-40, and had to include a different wingtip and instructions how to cut out a piece and glue, and ugh! Still no slats, not good. Then I saw that the Revell F-86D had slats. Eureka! Some builders have grafted this complete wing onto the Hasegawa fuselage, but it has some problems. Here is a comparison of wings They are quite different, and I salute the guys who got it right to mate them. The sweep angle and chord of the "Dog" wing are wrong for the SAAF Sabre. Here is a scientific study of the problem... http://www.clubhyper.com/reference/sabrewingsjh_1.htm (by the way the F-86F-30 wing is probably the same as the 6-3 wing). Any takers? |

For those that are curious about the different wings, here is a lovely post "demystifying" the subject: http://www.arcforums.com/forums/air/ind ... ystified/& Back to the question of how to get the slats onto the Sabre. In the above mentioned article you will see a mod which uses the entire leading edge from the "donor" kit, which is also how many of the resin mods are done. This requires a very neat cut to graft onto, and a lot of sanding and filling and stuff. I stared long and hard at the parts involved, and came up with the following solution. Since the Dog's slat is very close to the perfect length for the Mk.6's wing, why not just cut out the recessed slat leading edge with the roller-arms (made up name), then cut an opening in the Hasegawa 6-3 wing that exactly matches the now sliced up leading edge of the F-86D's wing, and simply mate the two. That way the basic wing shape stays correct for a Mk.6, it fits the fuselage perfectly since it's from the same kit (duh), and will hopefully require minimum filling and sanding and stuff. Like this... There is a very prominent hinged looking panel line on top of the wing. Notice the difference in distance to the leading edge, the Mk.6 having a broader wing. Then I had to pay attention to the lower half of the wing. On the right hand side it was slightly warped due a flaw in the plastic. and needed some metal to straighten it out - hence the brass rod. Once that was done, I promptly overdid the sanding to get a flat section like the original Dog's lower section. Styrene strip to the rescue. And here are the completed halves ready for joining. I messed up the left join a bit, hence the styrene filler. The lower half needs little openings to match the roller- arms positions. A fiddly job. |

Phew wee! A very elegant solution. |

Very nicely done . Is that Monogram D the same as the Revell D ? The Revell D was done by their A-team. Back to topic.... |

Hi Madmax An excellent solution to the slats. I would have gone the silly way to cut the front part of the wing and splice it. I forgot to mention the bump at the front of the fin fillet needs to be flush on the Mk-6 and there is no step at the slats. Most models have this wrong for all slatted aircraft. Regards your query on the F-30 wing. The F-30 and F-35(fighter bomber) originally came with the small slatted wing. With the Migs out-turning the Sabre at high altitude, 6-3 extensions were rushed to Korea. On the production line the 6-3 extensions were standardized from the 177th and 200th aircraft. The F-40 wing was fitted to aircraft for Japan but when the advantage of the larger slatted wing became apparent, most USAF F-30's were retro fitted with the f-40 wing, so it boils down to which aircraft at what time. So far as I can make out the Mk-6 was the only Sabre to have the 6-3 extension with slats but without the extended span. From pilot reports it was the ultimate Sabre to fly. Hope it clears it up.
