    Hi Paul,
    I can't put the rad under the cockpit. I think I have to reserve
    this space for a big muffler. I suppose noise regulations are quite
    stricter here as in the US. With a RV-4 the benchmark in Germany is
    around 63 db(A).

    If I plan to make a custom cowling, do you still need the length of
    the cowling? I thought the dimensions of the cowling will be defined
    by the design of the mount?

    Kind regards
    Thomas


    Ah yes. They will probably make you run a three blade prop
    too. OK back under the cowl with the rad. It is going to look
    more like a P40 than an Me109 :) (Bf109 ?)

I changed a few things on my aircraft- made the firewall 1 inch taller,
and placed the prop flange 44 inches in front of the firewall, instead
of the stock 39 inches. Also used .025 thick elevator skins and the
extruded trailing edges for the h stab. We'll see how the weight and
balance comes out- I can always change the battery position.

I don't know what provisions are made for engine mounting on the
renesis, but I imagine that it is similar to the generation 3, in which
case you can use a shertz beam type mount.

Brian Trubee

Yes that is what I did. Use a Schertz Beam. Here is a 3D Thomas.
P-port. Exhaust pipes not shown yet.
