How long should I keep my aircraft control throws set at minimum??

My rudder and elevator are both set up to give minimum deflection, my ailerons are at the middle. I was tweaking things last night, and almost decided to put the ailerons at max, (the only hole left at the servo horn moving out) but chickend out till I ask the experts.

She rolls fairly smartly, but not really fast. (Takes a good 3+ full seconds to roll completely around) While in flight the elevator seems quite responsive to me. Rudder, well Im probably gonna leave that alone for now since I am just learning to use it..

Takeoffs seem a bit sluggish, I get her up to a GOOD ground speed and slowly pull back; but it takes a second or three to rotate, and when it does it JUMPS into the air with a good 30 degree climb out. I've actually waited till she was nearly all the way down the runway moving with full throttle to rotate, and she still does this. I managed a good aproximation of a scale takeoff, gentle rotate and climb out ONCE last weekend. But she still wanted to jump up, I just reduced elevator throw as it began rotating up.

I ask, because I know when I get my second plane it will be more to handle than a trainer, and I want to start getting ready for it. (whether it be the 4* 60 kit I want, or a SPAD till I can afford the kit)
