RE: why is is that?
Have you ever flown a CP (collective pitch) heli before?
If not i suggest you take the 200 you gonna spend on the SR and buy a flight sim. or at the least buy a cheap sim and the SR. I strongly suggest if you have never flown a cp before to get some experince before you jump into a CP and crash it your 1st flight. When i first started and I am still new only been doing this since last christmas i bought a cheap 20 dollar sim it tought me how to hover some what but then went out and bought Phoenix flight sim and that was well worth it imo. I would not be able to fly my helis if i did not have phoenix flight to teach me.
Another option for you is to wait for the New Blade 120 SR comming out in August made by Eflite. The Blade 120 Sr is just a bigger version of the mSR and can handle more wind then the mSR for outdoor flight.
