[NSRCA-discussion] Park flyers for pattern practice?

[george w. kennie]

Tom,
I don't want to throw a little cold water, buuuut........, I've built a ton 
of these 36"-40" flat foamies and it's been my experience that if you want 
something to practice schedules with OUTDOORS you're never going to be quite 
happy with anything in this size range. The reasons are multiple. Most are 
designed to yield dual performance capabilities, i.e., 3D & Sport. Therefore 
they all seem to have an abundance of area. With an abundance of area and an 
AUW of 16-20 oz. there's no way they can provide the tracking you want in 
the wind because the wing loading is way too low. Great for hovering and 
torque rolling indoors, but bouncy enough outside to keep you fighting for 
any continuity of line.
What's needed is something a little larger with proportionally less wing 
area and enough weight to get the aerodynamic stability that the correct 
wing loading will provide.
I've built a couple of flat birds in the 48" range running 2&1/2 pounds that 
fly with the feel of a 40 size glow ship. They do however require larger 
motors than the 36" stuff and really like 4 cell paks, but the rewards are 
there.
Of course the Vanquish seems to combine all of these requirements and though 
I haven't flown one I've seen one flown in a contest in Advanced that 
impressed me.
The Silvestri Katana appears to track very well also and with a 32 size 
motor will vertical like a homesick angel.
There doesn't seem to really be a "best of both worlds" in the really small 
stuff.
G.
