Scottish Aviation Twin Pioneer - Modified Halam 1/72nd scale vacuforned

 

The second Scottish Twin Pioneer is ready to take off. The step-by-step building article can be consulted here:

Using the vintage Hallam vac this time around demanded more work –and resulted in a more protracted build- than the Valom kit build that can be seen here:

Still, it’s always good to exercise those modeling muscles with a challenge. This vac -which is rather simple- needed quite a bit of additions and improvements to elevate its standards, being a vintage kit. But hey, I love vacs as much as I love injected kits. And building them you learn a number of tricks that spill over to your “normal” builds. In this case a good one was to create the missing corrugations on all control surfaces with Archer “panel lines” transfers painted over. 

A full interior was provided, restroom included, as well as home-made decals and some small details, as the vac kit was very basic: 

This is not (and can not be) a comparison build with the injected Valom kit, as it’s not apples-to-apples, but it’s interesting to see the two different approaches to the same subject. Still, honestly, you are better off with the Valom kit unless you love the challenge, or have this vac kit in the stash and don’t mind the extra work and time.

Note: If for some reason you like the livery used in this build, beware that Valom's boxing of this very plane, G-APRS for the “Air Atlantique” livery has some decal and painting guide inaccuracies: The font for the wing registration letters is different than the ones on the fuselage sides of the real plane. Valom erroneously used the fuselage font for both. Valom also missed a black cheat line that borders the green areas on the fuselage sides and vertical tails, and erroneously states in the instructions that the Air Atlantique plane had green wing struts (they were grey as the rest of the undersurfaces). Valom made the wrong call again indicating green for the stab top, which is actually white like the top of the wing. The green fuselage bands do join where the tailwheel is, they don't end just on the sides. The surface under the wings (minus slats) and half the engine nacelles is light grey, as are the struts, lower fuselage half, stub wings and under-surface of the stab. The links below to photos online show that clearly. Not to mention the array of antennas and beacons that are not included in the Valom kit and are different for the two schemes offered. Valom even got the colors reversed (white and red) in the little square decal that goes close to the exhausts.

Regarding the previous build of this plane, I appreciate the effort Valom makes releasing civil kits and do buy them, even if they make me work more than other manufacturers, and need to be approached with more than a pinch of skepticism regarding accuracy.

As for this vac kit, for those of us who from time to time enjoy vacs or vintage kits in general, it’s always pleasant to take a walk down memory lane.
