or

depending on the weight
My problems are the weights like the weight at the front and back should it be balanced to be able to fly or could it be heavier at the back with the engline.
My other problem is what i should make it out of and how i shape it and attatch parts e.g. wings etc
Thankyou

Louis,
I'm working with Rotary Engine (single) and even if the design is nice, they can be pain. Very short life time (In extreme cases less then 150FH) - and overhaul is not cheap.
But they have some advantages, definitely. I personally would re command a turbine. (e.g. http://www.jakadofsky.com/index1.php?bereichID=4&lang=en)
