RE: Where can I buy/download plans for the PAU Edge 540 36%?
Some of your price valuations are pretty high, $100 in paint?, even your prices added up is much less than $1100 + shipping
Cowl, pants, canopy and covering are your bigger ticket items, but things like gear, wingtubes etc can be bought second hand for much less too, no need to plunk down full hobby shop retail on everything. Planes I've scratch built typically cost half what a kit built plane would have cost due to recycling hardware etc.
I think one could be built for more like $5-600
There was a guy on F-G that was giving away his designs of large scale plans until he got sick of the trolls and ARF fansboys bashing him there,, Could try and look him up and see if he'll email you a set of something you like. His user name is "Mode 1" and the thread is "Another free plan"
Good luck
