problems with stalls
Im not sure if this is the right section to be asking this but I do need help regarding power off dirty/clean configurations.
I seem to hold the heading correctly yet my aircraft wants to roll left or right on the recovery. I also find that I normally need to mash the left rudder on recovery to keep the aircraft from spinning out of control.
I would really appreciate any feedback or tips. I need to perfect these for the upcoming pre-solo check ride! thanks guys

That will make a difference on the responses.
During the recovery, keep the ailerons neutral.
The aircraft breaking to the left or right during the stall indicates an uncoordinated stall, so check your slip/skid indicator during the maneuver.

In addition don't "mash"anything in an airplane !!!!! smooth responses in all events should be the norm.

I'd bet a nickle right before the break you start yawing in one direction. You can't hold constant rudder pressure, you have to adjust it based on what you see. The dynamics change as you get slower and then stall.
Practice climbing straight ahead and using enough right rudder to keep that mountain/cloud straight. Look at the wingtips and make sure they are the same distance above the horizon for bank, keep the side of the glareshield from sliding left (yaw). Don't use the ball for right rudder during a climb. Use it only to verify what you have already done is correct.
Most important, get the AOA down. Even if the wing drops, do not try to roll back, it's very tempting, but getting the AOA down you get the ailerons effective again and then on the way back up you can get back on heading, although I've found even when a wing drops, if you get the AOA back down immediately, your heading doesn't really change.

Two things may be occurring; you're trying to use rudder the same way during a power-off stall as power on (and that's wrong), or you're carrying power into the stall, instead of approaching it at idle. The additional possibility is that you're rapidly applying power on the recovery from the stall and trying to make a rapid correction with the rudder.
Don't do any of those things.
Some instructors scare students with stalls, floating them in their seats, rapidly pushing forward on the controls, and making it seem as though there's a dire emergency in progress. There isn't. It's a stall. Reduce the angle of attack by 1/4 degree (let off an ounce or two of pressure on the controls) and you're flying out of the stall. It's not dramatic and doesn't have to happen hard and fast. Relax the back pressure on the yoke a bit, and you're flying, regardless of whether you apply power or not.
Practice recovering from a power off stall with, and without power. That is, approach the stall at idle, but after you break the stall by releasing a bit of back pressure, fly out of the stall without applying power. This shows that the airplane still flies and is still fully controllable without any need of power. Or rudder, or wild maneuvering or rapid pitch changes or anything else. Just a degree (or less) will do.
Try recovering from the power off stall with partial power, or by feeding full power in, but slowly. Note the way you feed rudder in, to compensate for the increasing power. Feed the power in a bit quicker; note the way you feed rudder to keep the airplane coordinated. Dont' be too fast with the rudder, don't jam the input in there, just feed the engine throttle, feed the rudder. The airplane isn't going anywhere.
Relax.
Flaps vs. no-flaps makes no difference. Just a different speed, but everything else works the same; reduce angle of attack just a bit, and you're flying again.
--on that note, you never stopped flying, but it only takes a very slight change in angle of attack to change the way the airflow over the wing occurs; in a stall there's a significant drag rise, airflow separation from the wing, and attendant loss of lift. Reduce a degree from the stalling angle of attack, and you have a rapid increase in lift, decrease in drag, and the airflow returns to normal over the wing.

You might want to get a few lessons in a tailwheel aircraft. You'll learn gobs about rudder control.
First, fly coordinated to start with. Then your job to recover from a stall with a minimum amount of altitude lost would be to first unload the wing - that is, release the back pressure. If it rolls, use top (opposite the rotation or the roll) rudder. Only after the wings are generating lift should you use aileron.
I learned gliding first and you can perform some pretty stunning stalls. Learned the correct method of stall and spin recovery from actually getting into fully developed stalls and spins. Also recovery from incipient spins and stalls. Then when I started power training, I was expecting some big hairy scary stall. Meh. Pretty tame. Easy to recover. Yes, if you are chasing the ball as it were, some planes will drop a wing pretty good. If you're really off, some planes will go right over the top. If they scare you at all... do more of them.

Far, far too much emphasis has been put on altitude loss in stall recovery. Forget altitude loss. Decrease angle of attack, get the aircraft flying, then look at altitude loss. Far more important to prevent exceeding critical angle of attack in the first place, but once its exceeded, minimal altitude loss is not the immediate concern; reattaching airflow to the wing with reduced AoA is, and often that's going to require altitude loss in the process.
Conventional gear aircraft teach about taxiing conventional gear aircraft. They're a bit less forgiving on alignment during landing, but beyond that, there's little magic in having the third wheel at the correct end.
