thanks, pretty much what we are doing.
I am going to put him on my esteem and psyko while we await an agea
mantis...
The dihedral sounds good too..
He seems energized about getting a new glider... so maybe he can make
the first few mistakes on the old stuff while we await a new ship...

First of all, the Spirit is not a particularly good-handling r/e glider.
It's wobbly in yaw, and prone to tip stalling because of the saggy
unsheeted tip panels. An AVA-type glider is much easier to fly well
I think, and of course it would be a huge step up in performance
for him. I'd avoid the full-house->RES converted gliders like
the Victory. They're heavy by comparison.
But if he really wants to go all the way to a full-house glider,
I'd go with something light and forgiving. The Aegea/Mantis is
an obvious choice at a reasonable cost. A DLG would be even better,
unless of course he's set on TD.
If you do get an Aegea, I suggest bending the rods for more dihedral.
This really helps in thermalling, especially for an aileron newbie.
There is no real downside to it. My Supra has 2.5 deg on the inner panels,
and 7.5 deg on the tip panels, and it can almost fly hands off as a result.
For the Aegea, I'd shoot for around 8-9 degrees on each tip panel.
