Perfesser

You can make the Spit more docile on the ground(or rather make the rudder seem more effective) by dragging the brakes all the time. Set your brakes up on a slider or trim wheel (an axis) so you can have them on a certain amount all the time. Near 4 on the brakes indicator is about right. It will taxi and especially land much easier.

I find the high sink rate you get when landing with flaps deployed is the major contributor to that landing bounce. Try to come in with no flaps, about 120 and then kill power over the threshold and just hold the plane a foot or two off the runway as long as you can with increasing elevator pressure.

Your airspeed is too low on takeoff. You should set your cruise control for a slightly higher speed. But airplanes have no cruise control you say.... of course they do.... elevator trim. Elevator trim determines the speed at which the plane wants to fly without control input. If you're dropping a wing on takeoff add in a bit of nose down trim.

I started with an X52 and CH pedals. The pedals crapped out pretty fast. I've had Saitek pedals for at least 8 years now but they're showing their age. I kept convincing myself the X52 stick was still OK for a few years but finally got fed up with the POS and got a CH Fighterstick that I'm still pretty happy with. It's solid and still precise after a lot of hard use. Still using the X52 throttle. A couple of buttons need extra pressure and the throttle is jittery sometimes but it's still reliable.
