Wayne,
This is a realy easy machine to make, If you like, your more than welcom to a copy of the plan.
It's only little at 635mm span, I'm streching the wings a bit out to 720mm In an attempt to ease the extra drag when pulling tight turns. Your more than welcome to a set of cores for the wings as well.
This airfoil should be very fast in a straight line but, on paper at least, it falls back to about par, as far as drag goes, when it's asked to produce enough lift to corner hard.
I'm hoping the extra aspect ratio will help a bit there. If my wing is not great It should be easy enough to make another to try, they just unbolt.
By all accounts the original design was a hit with the S400 class fliers in the UK back in the 90s.
It is very easy to make and depending on how it's powered it shouldn't be an ogre to fly.
It could have a much lighter drive system in it too. I reckon it would fly wickedly well with a 35 Amp esc, a 1000 4S and an $8 RareBear replacement motor. Should be faster than a RareBear with that set up because it's a much, much slipperier airframe. In that configuration It would be substantually lighter than the original Dyna-mite as well.
