I am currently looking to upgrade from my CX2 coaxial heli to either a Blade 400 or E-Sky Belt CP.

What I would like some feedback on, is exactly how LOUD are these Helis (the Two stated above? - dB?).
There are lots of reviews and specs all over the internet, but no where do they discuss how loud these craft are.

I ask this as over here in the UK our rear gardens are not as large as your Football (SOCCER) pitch sized gardens over there in the States!
And i dont want to upset the neighbourhood with my R/C Helicopter flying!

If anyone can provide further feedback it would be greatly appreciated,

Cheers,
Heli.

If nobody else comes up with some specific info by this weekend, I have a decibel meter at work and I'll get a reading for you.

What might be quiet for me might be loud for you. It sounds like Wolfpackin's meter would be the best way to go for how loud it is.

If you use an electric powered mower, that's pretty close to the sound level. The sound is probably similar to a household vacuum cleaner - far louder indoors than outdoors. The frequency pitch of the heli is fairly neutral, neither high pitched and irritating nor low and menacing.
Does that help?

Oh yes, please note that there may be considerable racket in the event of a collision with metal trash cans and vehicles, or wind chimes and such.

Status: offline 		Hi guys, i really do appreciate your feedback, it has been interesting reading.
I understand my question isn't your usual Blade 400 question, and I wasn't sure if there would be much feedback.

Well it's looking very positive, Wolfpackin, if you "could" come up with a realistic dB reading it would be greatly appreciated!
I should just think - stuff the neighbours, its my garden, I can do in it what I want !

evdreamer - a little louder than a CX2 sounds very promising - as i wouldnt call that Heli loud at all.
How does the Blade 400 compare to a Belt CP - which is quieter, have you flown both?

Thankyou also Soloboss for your feedback - we have an electric mower - used it just the other week!
The other thing, the Heli isnt going to be going out there for hours at a time, more or less, 30 minutes on a couple of batteries LOL.

I think im decided - I wont be worrying about making a racket, as the Heli isnt as loud as i might have imagined.
My final question would be - which to choose - Blade 400 or Belt CP - I love them both - but thats probably for me to do a little more research, and SEARCH these Boards

Thankyou all for your quick feedback - Im decided on the noise thing, just which to go for is next.............
Wolfpackin, if you do come back with a noise reading i look forward to hearing about it.

Over and out (for now), Heli. THIS IS SUCH A GREAT FORUM!!!!!

Status: offline 		I haven't flown the B400, but I would love to get my hands on one and test it out and a few other helicopters out there. But I don't think my LHS would like that idea too much. By Belt CP doesn't have many stock parts left on it, but it does have a B400 tail pitch slider. I fly my CX inside so it is quite a bit louder than if you fly it outside. The Belt CP and B400 are about the same size. The major difference is the stock head and transmitter.

I would say the 400 is not as loud as a vacuum, you can still talk to someone with it hovering. Little louder then the CX2. Start doing 3D with the 400 and the blades do make some noise, but again no louder then a car or vacuum.

I just checked my night job schedule.
If I can get it done, it looks like Monday night for the dB reading.
I'll see what I can do for you.

Status: offline 		If your back garden isnt overly large then you wont be doing much flying with the 400 sized heli anyway. I have a reasonably large yard (almost 1/4 acre block - thats bout 1000 square metres) with a not so large house, and I am not too keen on doing anything more than hovering within a 15 foot square for fear of loosing control and hitting the fence or a tree in the back yard.

I am heading off to the local flying field tomorrow to test it out in 'real world' and see what I can do. Hopefully it will come back n less pieces than it usually does...

Indoors seems much louder than out

Just a case of how sound your neigbours are really

Status: offline 		So the data is in.
I'm not sure how accurate it is but here's what I got flying inside large maintenance shop.

Ambient=44-48dB
B400=78-82dB

The readings were taken from about 10-15 ft away, while the heli was on the ground at 80% throttle and zero pitch.
It get slightly louder as the pitch comes in.
Sorry, I was not able to fly and use the meter.

i wonder how loud it would read if you had the decibel meter hooked up to the B400 while it was flying....hmm
