The R73-OPS is the same heli as the Syma S109G, it's just re-branded. You can get it prized at $39 us dollars or $30 us dollars.
It's very hard but not impossible to get it at $25 us dollars.
So, if you are interested, go to the first step.(description).
Step 1: Description!!!
For it's size, it has great detail.
It's 3.86 inches in height, 1.5 inches in width , and is 8.66 inch in length.
The main rotors are 7.48 inches each, and are counter-rotating.
The tail rotor is 1.18 inches.
The heli has two led lights.
You can't fly it outside because it uses a inferred emitter for the controller.
It's a three Chanel heli.
Even though it has a giro, it sometimes needs trimming.
One thing that I did not like is that it takes 40-50 min. to charge. And 5-6 min. of non-stop flight time.
Step 2: EXTRA PARTS!! :D
NOT ALL COME WITH THE SAME EXTRA PARTS!!!
Please read step #4 for why it is done. It might also be where you get it from.
This one came with extra blade parts.
Rear and main rotors.
Step 3: Flying!!! Flying!!!
Well, what can I say. It is super easy to fly it.
It's very responsive to the controls, and it can hover good enough. It drifts a little during the hover but not enough to make it move a lot.
Well, here is a video. I hope you like it.

Step 4: Charging.
Charging is very important if you want a working heli for a long time.
you can charge the heli by plunging it into the controller or to a computer.
The one for it to connect to the computer is sold separately.
If you don't charge it before storing it it will no longer work 9/10 times (most of the time).
But before you can charge it, you must weight 15 min. after the last flight.
For the USB charger, it is about $2.91at the most (used).
although mine did not come with it, I did hear that in some places soled the heli with the USB charger. But came with less spare parts.
Step 5: HAVE FUN!!!!!!!!
I hope you learned something in this instructable, and will enjoy the time you use the heli.
Well. That is it, for the R73-OPS indoor heli.
And remember to have fun and enjoy the rest of your day.
