Hello Anyone,
    I am currently thinking about starting a new project.. it's Going to be a
twin Racing Bipe made from 2 scat cat type airframes and wings.. what I would
like to do is set the spacing between the motors as close as I can possibly 
get
them.. so if one engine quits it won't be so bad to land it. I would like to
space it so the tips from each 8x6 just clear but I do not know if there 
ould
be any negative implications from that.. if anyone out there has any
suggestions on this it would be greatly appreciated.. aside from the odd 
oise
it would make which might sound neat.. I don't know if the props spinning 
hat
close would affect each others perfoamance. I'm almost certain there must be
some sort of ring or turbulance that should not be disturbed.. but I am not 
n
engineer. I would like to know if there is some sort of guideline or 
uggested
spacing for optimal performance.. As is it my hope to make a really neat hell
raising Pylon bipe.. what i plan to do is join the to airframes in the center
with some light ply and then make the tail simular to a P-38 as to how it is
joined in the back.. the basic design is a low wing plane so what I wanted to
do is build a little cabane on each fuse simular to an Ultimate and then bolt
the top wing on.. I know the top wing will be much further from the thrust 
line
than the bottom wing so I also wanted to know if there is any predictions as 
to
the performance of this plane.. I plan to have one aileron servo in each fuse
and 4 ailerons all together.. there will also be just under 900 Sq in. of 
ing
area. the power will be provided by either 2 OS 25's with tuned pipes or 
Nelson
mufflers or 2 OS 32's with pipes. If I run the 32's I will most likely run 
x6
apc's. If anyone has any information or suggestion on any part of this 
roject
that would be great.. After I fly this and everything goes well I will have
some plans drawn up and share them with anyone who would like it.. 
Thanks much
Neil Scavelli
Happy landings!
