As stated above, the costs can vary considerably depending on the parts decided upon, and the construction methods used.
Brass frameworks will generally cost more than resin / carbon fibre, but will be that bit stronger. The build will take longer though as there's a lot of cutting and soldering to do.
The landing gear can be built from less sturdy materials, and resin rather than aluminium footpads used. I decided to go strong with the best and most accurate landing gear available from Chris Trice - but there are cheaper options.
One thing you really can't compromise on with a build in this scale is aluminium engine bells, and there are two people in this business that I am aware of - Mike Reader and Paul Gray.
Be aware that the build will need to be very sturdy as there is a lot of weight cantilevered off the front & back ends which will tend to pull them downwards over time. This is not just another model kit and there are a lot of forces at work in the finished model which will need catering for with structural strength. The prongs from the landing gear pods in to the corridors also take a lot of stress so need to be as strong as you can make them.
Good luck with your build ! :yes:
