Thanks a bunch

RV9A Empennage

Planning is EXTREMELY important. Make cheap foam full scale mockups of every major 
part you intend to use. Arrange them in the cowling to test for fit and practicality.
Make a decision on what type and location of cooling radiators, air ducts and scoops you intend
to use. Get a digital camera and take pictures of your mock up and send them
to us for constructive criticism. Many mistakes have been made by others that
you should be able to avoid. If you do this well you could save years of work
and many false starts with many useless parts bought or made over and over.

If you have drawing skills get a copy of a good 3D program like Rhino or Solid Works
and learn to use it. Probaly less work than making a mock up. I can also 
send you some Rhino 3D drawings you can use as a starting point. If all else
fails send me a sketch of the RV9A firewall and nose gear and I will
do the 3D for you. No charge.
