OK,

I'm considering a Mazda 13B for my RV9A

Where do I start?

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.
