If anyone would like to give me some mental assist on the engine
mount/rad layout(Lord knows I need it....LOL), here is an ancient image
of the aft bulkhead of my ship uponst which I must install the pusher
engine/psru/prop and essentials. The bulkhead is approx 31" across at
each of the farthest points and is 3/4" birch ply strengthened now by a
T6 aluminum plate. The psru, a custom 3:1 belt-reduction is bolted
directly to the bell housing pattern of my NA 13B PPort, but naturally

I'd like to have it supported directly by the engine mount also. As soon
as I have the engine/psru put together, I'll post more pics of it
hanging in relation to the bulkhead, thereby giving a better image of
the layout and need for particular rad positioning. Basically, the psru
diameter is only slightly larger than the engine profile with it's depth
being about 9" farther aft than of the engine & the prop directly off
the psru with no extension. I would have loved to install some kind of
radding on the flat aft deck, but that's where I now have the ships' 62'
ballistic parachute mounted in it's 'flat-pack', so I'll have to mount
the rads in the aft cowl(still to be configured.)

PS: I like that 'folded core' rad layout. Mayhaps a set top and bottom
of the engine? Thanks, ya'll!

Where do you live Tim? I want to see this with my own eyes.
