Ace Bogie,
The cost is only $20 each if you make numerous errors and waste materials. $4 to $7 each airframe is about average.

The mistakes you made could have easily been avoided by simply posting your questions/problems on any of the various FREE forums, or by e-mailing Kraut or Tattoo directly.

The plans are FREE. The information that you needed to avoid the problems you had is/was FREE and readily available.

The people that put SPAD plans together do so on their OWN TIME and posted it at their OWN EXPENSE for the benefit of others.

You had problems because you didn't consult with the designers or take advantage of the readily available information on the various forums.

Please, stop bashing the good people that put the SPAD information out just because you failed at it your first time out with one of the more complicated SPAD designs.

Still have some Coro left over from your previous attempt? Give it another shot and be sure to share any problems on the SPAD forum so they can be solved.

Good luck,
D
