Wow Dent, quite a selection! I thought that was a T-Rex on the wall, also see the little yellow bird that I first started out with, the E-flight forget what name. It was the first electric helicopter I bought. Then of course upgraded to the T-Rex series.
Have not flown in it years. Ohh the memories of hard landings, having to re-adjust all the linkages, making sure nothing was bent. You are right about expensive. Running the to hobby store and having to get more part due to rough landings, charging the lipos off portable battery packs.
Wish I had the time to spend on it again.
Here is a pic of the last one I bought back about 7 years ago.
