rc helicopter servo?




T C


What is servo for? what does it do ?


Answer
A servo is a small motor that is hooked up to the reciver. When the reciever gets a signal from the remote, it tells the servo to move. When the servo moves, it is connected to a linkage that controls either the elevator, aileron, pitch, collective, rudder, or engine power. It does this by either pushing or pulling a ball link which pushes or pulls other links to cause movement of the main blades, tail blades, or throttle. If you are thinking about getting into the hobby, I would say go for it. Before you try to fly anything though, you should go to a flying field to talk to other pilots and get the required permits and license. Good luck, and happy flying.

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.

Good camera that streams live video for rc helicopter?

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.

A question on how to make an RC Airplane controled by a PC?

DELETED


Okay so I always wanted to do this, what do I need to make a RC airplane controlled by a computer and has like a camera attached for feedback? Is it possible to get mini jet engines? Is it possible for me to make a RC plane hover? If so how?


Answer
These things are all possible with enough $$. For example, check out http://www.cloudcaptech.com. The stuff is expensive, but it does what you want.

There are mini jet engines in the world, but they are extremely expensive, heavy and complicated for an RC aircraft, and they fly much too fast. I think what you really want is something that *looks* like a jet engine but is really a propeller. Those are called ducted fans, and they are small, cheap and easy to get from any RC model shop.

Any RC plane can hover if it has enough power--just point the plane straight up and give it throttle. If thrust>weight, it can hover. Hovering with the nose level (like a Harrier) is harder--it would require a dedicated lift fan, which I've never seen on an RC plane. In principle it could be done, though. But why not just build a helicopter?
