ORIGINAL: KitBuilder
Just as a point of refrence..
Scratch building is starting with nothing... but a pencil, various drawing tools and calculator (or computer
)
Plans building is staring with the plans already drawn up or purchased
kit building is starting with... well a kit...
What your doing is well... neat... between plans and kit buliding...
So, if you take the existing plans and use them as starting point to draw your own, adding main gear retract attachment points, wheel wells, flaps, retracting tailwheel. Modify the whole fuselage to allow for access hatches in the tail, battery hatch in the front. Changing how the wing attaches to the fuselage. Etc, etc ...
Are we then still talking "between plans and kit building"?
I used the plans as if these were 3-views, using their outlines to build my own. Redesigning formers from the outline of the existing ones on the plan (as if these were cross-sections).
Now if you still believe this to be "from plans" then to each their opinion, which I'm not going to argue with.
Whatever it's called I did, I had fun doing so ... and had some less fun moments as well.
