Dwarf gyrocopter revisited.

I'm currently undertaking my third (and hopefully final) attempt at assembling the GW Dwarf gyrocopter. My previous two attempts, using two different types of superglue, were to no avail, the complete assembly falling apart on me. The kit was therefore put aside for quite some time (well, over 12 months actually) and I've finally decided to take it out and try again.

So.. a little research on the web first, and I find comment that this may well be rated as the most difficult assembly in the entire GW range.. fantastic!!

The consensus was however pretty clear: you need to pin the model, especially the rotor assembly. So pin it I did. The holes were drilled with a long unused motorised drill of French manufacture, and pins were inserted down the length of each blade, and throiugh the hub itself. It was glued with two part epoxy. I also picked up another very cool tip: glue the rotor hub to a washer - inspired!!

So here is a photo of the rotor assembly from the underside at that stage.


I then went on to strengthen the hub further with a band of green stuff, creating what now looks like an elegantly enlarged hub, perfectly in keeping with the concept of dwarf engineering.

The landing skids also required pinning, and the assembly is now being painted - photos to follow.
I haven't been this challenged with any model since I used to scratch build models of ships and aircraft as a teenager - those were the days!

  1. I've seen a couple of practical solutions for this model (I have 2 of them self)

    Make your own propeller blades using plasticard (haven't tried it)

    Its possible to build the model w/o pinning - you need to build a support using paper clips, bracing the loose blade off the main piece while the green stuff and super glue dry.

    BUT, when I get back to repairing mine for the 3rd time...I'm gonna look for a small washer!
