It's a genuine Trex 700 nitro, don't think HK do a copy....yet ;)

The main reason I've not got further with this project is I've probably spent 2.5k on helis in the last 18 months to the exclusion of everything else!

They cost £15 + the dreaded and P&P so I think approx £25 in total...still got about 130 left :)
