Yeah I got one. At the beginning of the summer. The t-rex 500 just rocks. I should put up some pictures, but I've been too busy flying it.
The website, the electronics stuff etc have all been on hold while I get some good outdoor flying this summer. I have to say I'm getting a lot better.
This heli is just amazing, the power to weight ratio is awesome. It is also a lot more stable than the 450. The size difference is marginal. Though it is bigger the additional stability from the 450 to the 500 is much greater than you would expect. It has given me much more confidence, and I'm realy solind in forward flight now. It is definitely the most badass heli I have flown.
After flying this heli I rebuilt my 450, it was pretty smacked up after many a crash, so I went through the whole thing, the head, and checked all the bearings. I replaced a few bearings, upgraded the ESC firmware, and set it up all over again. It is really smooth now as well.
I think I will just maintain these two helis, they both fly great, and if one goes down for repairs, I have another. They are both great quality.
