Ricky2000..... As for the Mustang.... Make a new kit off the old/new parts and build the the ...stang with the new parts you've just created. Might take note on the the original parts is to compare the size(s) to the plans. Granted plans can shrink/expand through time, but, if your going to make a kit, might as well make the parts accurate. Yes, it would be LABOR intensive, but the goal would be still having an original kit etc.
I am glad you like the thread, I am the original "poster" of the thread. I scratch and build from kits, and have assembled a ARF or two, but that's my limit though I am currently finishing up a .15 size Mustang for racing, it is an ARF... but being safety concious and wanting the plane to fly straight and true for the rigors of racing, I "bashed" it to my standards within all the rules listed in our club. I wish now I would have "scratched" one as it would have been exactly what I wanted as for the build and flying characteristic's, I've put in to much "time" in this one in making it "right".
I've heard that the Nosen kits tend to be "weak" in certain areas, first of all, I've seen one or two Nosen Mustangs years ago that flew. That's my expeirence with this particular "kit". If you do decide to "make a kit", a suggestion is to review what the plan reflects for design, the type of wood being used for that particular area and how that area would affect the safety/build/flying on a whole.
Just my two cents worth !
