small rc helicopter engine image
Andre Fost
I want to be able to stream live video from my rc helicopter. I don't want to spend anymore than $50-70 dollars on it. I would prefer being able to stream live video from my andriod phone to my computer so I can see it while it records.

This is the best i could find, going any cheaper you will either get bad signal or not-so-good quality video. This will not stream to your phone, but can stream to a tv, i used to do the same with my rc truck. I simply got a small tv and put it on the porch, turned the camera on, started the engine on my rc truck, and sat down and drove. It brings a new level of control to radio control.
Remember though, the camera may only weigh a few grams, but is powered by a 9v battery, so make sure your helicopter can lift it,otherwise you may have to get a larger helicopter.

What does determines the weight that can be lifted by a helicopter?

I am trying to find a RC helicopter able to lift objects, what determines the weight that can be lifted by the RC helicopter? The RPM of the blades? the blades' size?
Thanks
Answer
in real helicopters, a lot of factors.
for the most part, those can be reduced to engine power and main rotor efficiency being the critical point.
engine power AND altitude/temperature are the most limiting factors for slingload operations, where you HAVE to hover with your load.
for internally transported payload, you can use rolling takeoff/landing, which enables you to lift more.
the MTOW and mass and ballance and other factors come into play, too.
for your application- be sure your payload is placed as close to rotor axis /center of gravity as practical.
anyways, for practical reasons all the "decorations" common RC helicopter has, they can be all removed and replaced with payload.
in small RC helicopters, the RPM of the rotor influences the lift. in real life, we use collective pitch.
yet increasing RPM is not a cure for everything. you have to observe blade loading from centripetal forces etc.
