Paul,

        Air doesn't bend very easily.  Blanton proved this over and over
while leaving steam trails after only minutes in flight, with a rad moiunted
much like your example.  One solution was to put in 2 rads (one on each side
of the engine)  each at 90 degress which simply generated twice as much
steam.

        Heat and plumbing installion people will tell you (rule of thumb)
each 90 degree bend in a given pipe diameter is equal to 11 feet of straight
pipe.

That's funny Neil I never heard that story about Blanton. I'll have to 
remember that and bring it up next time I want to bad mouth Blanton :-)

Everett's rad was in there 90 degrees and Allan made it from CA to Sun &
Fun 
a couple of times so it must have been something else Blanton was doing
wrong. 
Course Everett never got it to cool on the ground as I recall. Allan had 
a little trouble at the last Sun & Fun 100 mile race waiting to take
off.

90 degrees is real far from  the best but it can be made to work. As I
understand 
it sealing is *EXTREMELY IMPORTANT *!!! If you look closely at some of
that 
German stuff I faxed they had a few 90 degree examples that worked
pretty good.
