when i was playing with my RC Helicopter it fell and it couldn't rise anymore it just spins in circles... the module type is Vision SO10 mini 3... pls help!


Answer
In a coaxial copter like yours, the tail rotor serves to pitch the copter to go forwards or backwards. The coaxial blades spin in opposite directions to counter act the spin force that a tail rotor would otherwise handle.

What this means for you is that one set of blades is spinning faster than the other, causing the bird to spin around. If you have a trim adjustment on the throttle stick, you can use it to make one motor spin faster than the other. Or, to balance them out rather.

How do I Make a RC Remote?

I lost the remote for a Brookstone Silver Bullet helicopter. I know that it's not a big deal, but I don't just want to throw it away. If you don't know the answer, can you think of some creative ways I could use the parts of the helicopter? By the way, this helicopter still works perfectly and the romote uses an infrared senser. Thanks!


Answer
You could try contacting Brookstone and see if you could by an extra remote. Or, since they seem cheap ($29.99) just buy a whole new helicopter/control, and then you'd have an "extra" helicopter for parts. http://www.brookstone.com/mini-remote-control-rc-helicopters

Trying to build your own remote would be next to impossible (unless you're an electronics engineer, in which case why are you asking?)

Another possibility is to try a different brand of helicopter, such as the Blade series helicopters from Eflite. They are quite a bit more expensive, but they use what is called "Bind N Fly" technology which allows you to use better transmitters for the helicopter if you wish. As well as the Blade helicopters are fully repairable down to the last little screw or bit of plastic. I have the predecessor to the mSR X, and I love it. Tough as can be, challenging to fly (if you've never flown a heli before) but once I learned how to do it, it is tons of fun.

the Blade mCX coaxial helicopter (similar to your Brookstone in that it is coaxial)

or
the Blade mSR X which is a single main rotor with a working tail rotor. Harder to fly, but much more realistic looking.
