I've slowly been working my way up the glider food chain (foamie, built up,
composite, etc..) and now have a couple of planes which I need
help/suggestions setting up. One is an electric Graupner Cumulus 2000,
which has ailerons/v-tail, the other is a Flamingo HLG which has full
ailerons/spoilerons and a v-tail.
I've got the basics down and can fly the models as they are setup now
without any trouble (in fact, both are really nice planes for where and how
I fly), but I'm looking to learn more about the performance gains that can
be had by making minor adjustments to the control surfaces.
I often read here about folks adjusting the camber/reflex on their planes
while flying to achieve various results. I haven't been able to find a
source for information on how/why and how much these settings can affect a
plane's performance.
For example, on both these planes, I have a trim knob on my Futaba Tx which
allows me to change the aileron trim up and down to provide reflex or
camber, but I have no idea what the appropriate control throws should be..
is 1/8" (just picking a random amount) a little or a lot when you are
changing the profile of a wing? What guidelines should I use to set the
appropriate range of motion, and when should I use each?
Another question specific to v-tail/aileron models.. how many of you fly
with rudder/aileron coupling? Right now I have both of my planes set up so
that I can switch between coupled and uncoupled modes, but was wondering
what most people did? Do you like to 'fly' the tail 100% of the time, or
prefer the simplicity of 'setting it and forgetting it'?
Thanks for any help..
