Mac,
It sounds like you have it figured out correctly. Build on and have fun. If
you still have doubts drop an email to Van's.

Most of the builders in our group use one long bolt going all the way acros
s each peddle instead of the two short ones Vans recommends.If the brake cy
linder rod is depressed at all brake fluid will not pass through it. (will
not be released) All the brake cylinders must freely return to the non appl
ied position.

| Subject: | Initial biuld decisions |
First of all, I thank all who provided me with input in making the decision
between a 9A and 7A. I have decided to build the 7A. It has not been an
easy decision. Basically the balance tilted towards the 7 after considering
the Vne and the added performance with the 360 engine.
Now I would like help with a couple of other decisions. First, IO-360 vs
O-360. I was leaning heavily towards the injected engine, carburetor heat
being the issue. However, after attending an EAA meeting this morning and
talking to an RV-8 builder with a beautiful 8A with an O-360, I'm no longer
sure. What advantages does the fuel injection have? Performance?
Reliability? Ease of installation? Maintenance? Any other? I believe cost
and weight penalty are close for either engine.
The other decision is between Constant Speed and Fixed Pitch prop. It is my
understanding that the CS will provided better takeoff and climb figures and
marginally better cruise performance. I'm wondering if this performance is
worth the extra $6500 or so for the CS. I'm leaning towards the FP
implementation, but I would like to hear comments.
Thanks and best regards to all,
Rafael
