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

mini rc helicopter with built in camera image

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?

how can you build a RC helicopter ?

Q. My friend an i want to build a powerful rc helicopter with a wireless cam that has a good range but we have no plan on how to build it and where to buy the stuff for it

Answer
RC Crafting was once a exciting hobby enjoyed by all ages, but nowadays with smaller and cheaper electronics, it has long died as an art form. The sheer joy of detailing a minature craft and watching it take off was the Nintendo of yester-years.

The fact that you specified a wireless cam as an attachment leads me to think its not RC'ing you two are interested in, but rather sight-seeing or dare I say, spying, is what you are exactly looking for. In that case they already make something like that as a toy. It has limited range and either a b/w camera or a colour one. Some have mini monitors built into the controller, and others require pc or TV hookup for the receiver.

why wont my mini rc helicopter fly outside?

mini rc helicopter how to fly image

Neil J

no its not the wind. im talking about the copter doesnt react to the remote like it does inside. outside theres more of a delayed reaction. tell me why is that?

Answer
It is because your helicopter most likely uses infrared technology.
So when flying outside...
It does work, but the signal is just shortened. The range of an IR signal is usually limited to around 30 feet or less. Infrared, also called optical control or opti-control, requires line-of-sight, that is, the LED on the IR transmitter must be pointing at the IR receiver in order to work. It doesn't see through walls. Depending on the strength of the IR signal and interference from sunlight or other infrared-transmitting devices, the range may be shortened. These limitations make IR unsuitable for RC vehicles intended for long-range flight, outdoor racing, and other activities where it may be difficult to stay in range and within line-of-sight.
So... now you know... Let me explain what you might see when you go outside and try. When you go out, you will try to fly your helicopter. It will work, but after a while, itll start flying by itself, and youll lose contorl. It will work, its just that your range is incredibly shortened.

Now, if your helicopter had an antenna on it, and it isnt using infrared technology, then it is most likely due to interference. but I doubt it.
Does your remote look like this:

something like that with a red thing on top? If yes, I answered your question properly.

What kind of rc helicopter should I be getting?

Chance

My dad is going to be getting me something for Christmas, $85 limit. I want a rc helicopter. Ive only had cheap walmart ones before, so i need some expertise. Im wanting a namebrand fairly decent sized helicopter that will be able take some minor crashes. I did a little research and it seems that the Align T-Rex 250 is decent. Any ideas? Remember I have $85 to spend, including taxes and shipping.

Answer
I wouldn't recommend the Align T-Rex 250, and it's over the budget anyways? The smaller the helicopter, the more crashes it can resist, and the cheaper the replacement parts are. Just the battery looks like it's 3 times more expensive than a mini helicopter, and you will need extra batteries if you would like to fly for more than 10 minutes.

Do you have a radio/controller already? If you do, you could buy the BNF version of the helicopter and it will be cheaper. If you don't, then look for the RTF version that comes with a radio/controller.

The Blade MCX RTF is $80 at Horizon Hobby

It's a coaxil heli, so you will have to fly it indoors and outdoors only when it's not too windy. It can take a good beating, better than the t-rex, and the parts are pretty cheap.

These 3 are some I have looked at while I was doing research about rc helicopters when I wanted to purchase one. These are fun, you won't be able to do 3D tricks with them though. It depends how many channels was the one you had, these are 3 channels and good practice.

The Syma S107 is $27 at amazon. It's a beginner helicopter, but it's small and reviews say it does good in taking crashes (4 out of 5 stars).

The Helizone Combat fighter 3.5 Channels looks fun. It's $36.99 on amazon, and you can look up videos on youtube.

The Syma S107C has a built in camera, and it's $39 on amazon.


I purchased the Nano CP X BNF, and a DX6i receiver, and depending your age and experience, this is not a beginner one. But it's just something to look for in the future if you want to get into the hobby. The heli cost me $160 online, and the reciever/controller (DX6i) cost me $70 USED.


You could also suggest to him to look on craigslist for used ones, don't be uptight about it and demand a new one if your father can't afford ones over $85. I bought the DX6i for my boyfriend from craigslist, and it came in original box and everything, for less than half the price, and he loves it anyways. You could find a used Blade MCX or MCX2 for a really good price, and if it's from a person that looks like it's their hobby, it will probably be very well taken care of.


you or your father should check out this forum's for sale threads:
http://www.helifreak.com/forumdisplay.php?f=6

you can also feel free to ask questions on there, or check out the "newbie" section for advice, there has been many people also asking for a beginner heli, so you can read the responses.

Don't try to get a "professional" type helicopter because for those you need to make a bigger investment than just the helicopter. For an advanced heli you need an advanced radio, not the ones it comes with, and you will need to purchase a simulator to practice on because crashing the helicopter will cost you a lot of money!

Goodluck and have fun :)
