Okay, I know I'm going to get bashed for this, but I'd rather you try the following before you hang it up. In this order!

1) If you can't find an 'instructor', see if you can hook up with someone from the club that has a good deal of experience and you can use a buddy box. Let them teach you to fly.

2) Try another club in your area, if possible, difficult I know.

3) GET HIGH and gain some altitude! Slowly and meticulously find your planes stall speed, meaning where the stick is when you can’t climb out and it drops. REMEMBER that position!

4) OK, you state you've had 3 decent flights with possibly some 'rough' landings. If you MUST go it alone, fly on the calmest day possible, make sure batteries are FULLY charged, and practice taxing the plane at this large field.
•Now PRACTICE, PRACTICE, PRACTICE, making approach landings at about 200 ft altitude.
•First go downwind, make your upwind turn, then your final leg, keeping altitude, and pretend you’re going to land. Get a good feel for your planes tendencies. Are you comfortable with it, if not try again.
•OK, once comfortable, we want to execute a fake landing. Meaning you are going to pretend the deck is at 50 feet. Set up as previously stated, and ‘land’ the plane at that 50 foot imaginary runway. Now come around again, but this time, I want you to keep the speed up (less than ½ throttle or whatever is just above stall, remember the decent is going to give you some speed)
•Just before you touch down, or if you’re not comfortable with the approach, give her about ¼ throttle, and pull up gently. Make another attempt.
•As long as you keep a decent enough speed and there is minimal enough wind, you should be able to set up for a good landing.

NOW keep in mind I have NEVER seen you plane, checked for balance, range check, linkage check, etc., etc., etc.,….are you getting my drift?

Good luck, and hang in there. This is an AWESOME sport! Not a hobby, as I feel hobbies are something you do to pass the time…HEY are we passing the time or having FUN!?!?!
