Good idea Chrissi. Dress the engine first and then figure out where

to put

the mounts.

Paul, we totally agree. This should be true for anyone on any plane. We

are accumulating the essential and non-configurable parts first, then
prioritize what will go where. After the non-configurable parts I'd say a
sound mounting structure would be a high priority. It seems that you
could mock up and explore to your heart's content with foam blocks and
wooden dowels

  When doing this dont neglect things like radiator, oil cooler,
intercooler, etc... And also include necessary ducting to/from those items.
Finally, give some thought to the cowl line. I thought I had this all
worked out on my RV4 installation but in hindsight could have done better.
On the very narrow RV4 the cowl line dictated the positioning of the lower
motor mount points which in turn dictated positioning of the rad and oil
cooler. Of course this was all based on what I thought the cowl line was
going to be because I didnt have the cowl at the time I made the motor mount.
  Turns out that now that its all built I see that I could have spread the
lower mount points a bit and fit my oil cooler down there beside the rad.
Would have greatly simplified the oil cooler ducting and would likely have
worked better than the compromised oil cooler placement I have now.
