Heck, not even close to your highest figure. An average engine for me starts at $800.00 and goes up from there. My newest plane just cost me $2700.00 and that is just the airframe, then I'll need a minimum of 13 servos at roughly $100.00 a piece, an engine that is around $1200.00, smoke system, etc...

But here are my 3 favorites. The first one is an Aeroworks Yak. Total invested is roughly $2200.00, then my Ulitmate for around $1300.00 and finally my Cap232 at around $1200.00
I'm still getting together a 33% Wildhare Edge 540 that will be close to $2300.00 when finished.
Now you may ask how I can afford all of this. I'm lucky, I'm single, have a great job that pays and my company is very supportive of my habit (most of the upper management are full scale pilots) plus my current G/F loves my toys, plus she make a very good living as well so we both have our "play money". I'm working on getting her son and daughter involved. He's not too interested but she is.
