Just wanted to give an update in case anyone reading this was interested in reading another opinion on the plane. Well, the tape didn't work too well to keep the wing flaps in place so I broke off a peice of wire from a paperclip and I placed it under the airfoil and then I taped the paperclip down. It flew relatively well like this, although it still has a tendency to go to the right sometimes, it's not nearly as bad. I only adjusted one of them because I was trying to avoid putting unnecessary weight on the plane, so I'll play around and see if I can get better results.

As micro said, going full throttle all the time isn't very good as it stalls and then spirals down, and turning the rudder too far for too long is also bad as it'll make the plane dive down. All in all, it isn't too bad for 20 dollars, but I can't get more than 3 minutes of flight out of this and it ends up in the ground more than I'd like. I've never flown a plane before, but I felt like you had to get to know the plane a bit to keep in the sky (which I still can't do for too long), giving it too much or too little throttle will make you end up on the ground, and if the plane starts turning because of wind, I have to compensate with the right stick to make sure it doesn't make too wide of a turn or it'll end up in the ground, and then again the throttle needs to be adjusted as it starts turning because too much throttle and it'll spiral down, too little and it'll just fly down.

So far I've had more fun with the picco z as getting it to fly and stay in the air is much easier. Maybe if there was an easier way to adjust the airfoils I might be inclined to give a higher recommendation for silverlits single winged plane. The instructions tell you what to do to correct for abnormal flying, but they don't tell you how to do it, hence my crude paper clip in the airfoil.
