Joshua,
Depends on what you mean by "low ceiling". Cat 1 gliders are always launched
straight (no spiral climb). Gliders for a 50 ft ceiling are launched like an
outdoor glider, in a right bank so that they turn right/roll left on the way
up. These usually have larger stabs than cat 1 flappers.
For Cat 1 most guys just use left rudder for transition and glide turn. Stab
tilt doesn't work too well on Cat 1 gliders because the stabs are so small
and CGs far forward.
Basic aerodynamics: large stabs increase stability but make transition
tougher. Smalls stabs are good for transition, bad for stability. Knife-edge
stability is okay for indoor gliders because they don't have turbulence to
upset them. Rudder adjustments are very effective at high speed so small
amounts can be very effective.

While ya'll are explaining that, could you also give some advice on trimming
low-ceiling gliders? I built one recently and the trimming process caught me
by surprise to say the least.
Good flying,
Joshua Finn
