I have had 3 open class TD gliders with the 7037 airfoil. 1 Genesis, 1 Victory
(obechi) and 1 Victory C (C/F). The Genesis was
definitely the fastest of the 3. It has less area and weighs more than the Victories.
It would perform well with ALOT of camber dialed
in once it was in a thermal. The Victory was quite a bit slower. It has larger flaps
than the Genesis, and would slow waaay down
(comparitively). It too, would do well with camber, but just not as much. If too
much was dialed in, the handling became sluggish and it
would want to fall into a turn. The Victory C came in about 4-1/2 ounces less than
the wood skin version. (lighter tail, CF pushrods,
gear farther forward) It flies very noticably slower than the other two planes. It
also seems to perform better with less camber. It
will circle slower than it's predecessors without dropping a wing or the nose. ( I
added trilerons to it, and now it will really hang a
wing tip.) I haven't yet ballasted it up, as it still penetrates in our mild SoCal
winds. I have a hollow steel wing rod that I have
been planning to fill with lead, so I will try it soon (yeah, right).
So, what airfoil do you want? How fast do you need to go?
