Quadcopter FPV Simulator - FPVFreerider Free Demo

Nice little simulator, still it's not realistic enough... but it's only $5 (or free if you use the demo version), i can't really complain! Works well with my Taranis, I strongly recommend it to beginners :)
I have only tried the free version. After a few flights, here are what i think.
- delay with stick control
- too much drag, but that makes it a lot easier to control than real life
- even with high rate, it's still not high enough, can't do any crazy flips and rolls
- camera angle not adjustable
- simulation quadcopter not powerful enough
- we need wide angle camera view! :)
- multiple player? online and local?
- compete with your previous flights (shadow quadcopter, like that in Mario Cart hehe :D )
- PID tuning to change flight characteristics?
update:
some of the above point is available now in the paid version:
- drag, and angular drag
- gravity
- rate for roll/pitch and yaw
- camera angle
- camera FOV
