I'm putting the link for the Jumper X73S here just so you can look at the specs, or if you still want to buy one. GearBest still has 'em: .
I will be keeping this one as my acro practice flyer as it is pretty durable (when the props stay on that is). There are a few things I had to do to shore up all the weak design points, but once I did its an ok performer. I just never know when the props will fly off.
These props work a whole lot better and performance is retained: .
