Hi Aaronw ,
I've had mixed results with my to previous Mach 2 builds .
My HH-43 build stalled a while back , although most of the hard work is probably done and would only require a little more effort on my part to finish her off .
The biggest issue is the fit of the front canopy , lot's of filing and putty required
I decided to cut open the cockpit and cabin doors and remove the clamshell doors from the rear . I also changed the cockpit seats and added a couple of pilots .
I had better results with the Mach 2 , RC-3 Seabee .
The Seabee was a much easier build and I'm more than happy with the finish model .
