Hey Virginny: Naw, don't quit. If you flew your Telemaster inverted over the cornifield you must be pretty good and just maybe you've got some folks a little jealous of your flying ability.
The suggestion to build models to sell in order to raise money is a good one. Electric would require a larger investment.
Suggest you stick with what you have but I get the impression that you are not taking care of the little details. Sucessful flying is 90% details right from building to first flight. The other 10% is actual flying.
So take care of the details and don't get in such a rush to get something in the air.
May I suggest you look at a Funtana .40 or 90. These are great airplanes and fly like a feather.
