Why does my RC helicopter spin in circles?

Jessica

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.

The tail rotor on my Mini RC helicopter broke and I have a replacement but I need help.?

I have the replacement, but when I put it on, it spirals out of control. If I look at the original and the replacement, they look identical!

What is wrong and how can I fix it?

Answer
You need to make sure you have the tail rotor oriented correctly. It is possible to install a tail rotor backwards in some cases, which would just make your heli spin like crazy.

I could give you a better answer if I could see/knew exactly what type of tail rotor you have. However, generally the tail rotor must blow air to counter the rotation of your main rotor blades.

E.g.:
- if your main blades rotate clockwise
- tail rotor pushes the tail clockwise also

This stops the tail's tendancy to rotate counter to the direction of the main rotor blades.

Alternatively, depending on the type of heli, you may have issues with your tail gyro adjustment, tail gyro direction setting, or tail servo linkage adjustment.

Hope that helps

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.

What is the Titan 450 V2 RC Helicopter like?

Jasper Han

Hey, I am reasonably new to the hobby, and i am also cash strapped :) is this heli any good? will it cost more in the long run than a blade 450? i know the blades are gonna be better quality and everything. But will the Titan give me a few years? also can you get parts from them or do the Trex parts suit?

or maybe you have another suggestion for a cheaper collective pitch 450ish?
Thanks

Answer
Have you ever flown? Do you have a good simulator like Realflight ( www.realflight.com ) or Phoenix? Have you ever flown Collective Pitch? Fixed Pitch? What is your background.

The mini titan and the blade 450 are both good 450 sized heli's. I would however suggest an Align T-Rex 450 SPORT (not pro!). Belt driven heli's are easier to fix and until you get good I would not suggest a torque tube helicopter like the T-Rex 450 Pro.

If you want to go a little bigger, Try a Compass Atom 500 or a T-Rex 500E (the belt driven version!).

One more thing: If you're cash strapped, this hobby isn't for you. A great first collective pitch helicopter is infact the Blade MCPX...don't overlook this little bird. If you're strapped for cash right now, that's the way to go and chances are your local hobby shop stocks parts for it. (check it out at www.bladehelis.com) Hope this helps and enjoy this great fun, hard and rewarding hobby my friend!
