I have the Tower 60 Trainer and I love it. I'm sure it will not withstand too many hard landings. A friend of mine is learning on a Sturdy Birdy and that plane is almost indestructible.

Here is a link to the Sturdy Birdy if you would like to take a look at it. I am pretty sure it is a 40 size plane and that will save a bit.

My first radio was a JR 5 Channel and it should last me quite a while and it came with the complete flightpack. I have since purchased a 6 channel JR because I'm an addict.

With all the support equipment you need I don't think you will get flying for much under $500.00. Unless you can borow stuff from a friend. My estimate may be a tad high but buying a plane, engine, radio, some fuel, and a few flight line tools, I think $500.00 is a safe figure.

Good luck and keep us posted. This is one fine hobby.
