With the winds that you have electrics are going to be "dicey" at best (as you have most likely already found out with the Aerobird ) because of their light weight.

With winds averaging 10 mph, I feel you would be better served with a glow trainer. Because they are heavier they can handle/penetrate the wind much better.

Unfortunately, I have to STRONGLY suggest the instructor, club thing because glow planes not only fly faster (and respond MUCH faster ) than electrics, they also require a larger space to fly in. If you go this route, again because of the wind, I would suggest the Hobbico Avistar for a trainer with a ball bearing 46 engine. This plane has a semi symetrical airfoil so it will handle the wind much better than the traditional flat bottom airfoil.

On a personal note, I ALMOST lost a twin electric CL-415 (Scale Water Bomber used for fire fighting in Canada ) because of the wind the other day (about 12 mph ). I am a reasonably experienced flier and this plane weighs in at about 64 ounces RTF. I took off and the wind got it and took it about 1/2 mile from the field in about 40 seconds. I finally got it back to the field, but the landing was "less than perfect" I also flew my Bingo that day (40 size 4* clone ) and had no problems. Of course the Bingo weighs in at 5 lbs 12 oz dry - a little over 6lbs with a full tank of fuel.
