Trimmers during flight

Perhaps this is a stupid question folks, but I have been wondering about something for a while, and I figure it's better to ask first before trying it out in real life.

I've been flying since 1994, but I have never had a glider with trimmers. How will a speedglider react if using the trimmers in flight? Pulling them evenly on both sides is surely not a problem, but what reaction will be provoced if pulling the trimmers asymmetricly? Will it turne more radical than when using the brakes? Will it become difficult to stabilice it?

This is a security question, not a "acro" question:)

I fly a Nano 14 by the way...

I am no expert and not 100% sure what you mean, but...

Trimmers should be adjusted as pairs as they adjust the angle of attack or pitch of the wing. IMO should never be adjusted asymmetricaly to turn the wing as you cant reposition them quick enough to re-correct. Also you will have to release the brake to do the adjustment - Not really the thing to do when trying to turn in the same direction.

Pull on the brake to turn, which should also put pressure on the riser which will help turn the wing quicker, as does weight shifting into a turn. Another key factor is flying speed - slow speed flight will give slow unpowered turns.

Trimmers control the amount of glide and speed you have.

Copy of text from the manual -
The front and back risers of the NANO are fitted with trimmers that enable the pilot to adapt the
glider’s behaviour according to his level and the chosen slope. Trimming the back risers makes
the glider smoother, more forgiving and slower, suitable for beginner pilots, or pilots who have
little experience. Trimming the front risers enables expert pilots to enjoy a more reactive glider,
with greater speed and lower flight angle, to follow steeper slopes.

Thank you! My question is

Thank you! My question is just out of interest in knowing how the glider will react in case of using the trimmers in flight. I do not want to try this out my self, and I do not see that I will ever need to either. Anyway - thanks for for your respons:)
