noise complaints

[themagician]

seems like we have a glut of noise complaints in the staffordshire area of flying clubs,strange as for the last 20yrs at our club nothing at all,
could it be a disgruntled member from one of our clubs or could it be the local authoritys just flexing there muscles to keep us on our toes????
checking to see if we have anything better to do.
have any other areas seen an increase in complaints lately.

nope not heared of any down our way mate sorry to hear of your problems liam

[glen_j]

nothing down my way but we fly in the middle on nowhere

The fact that several clubs have all received noise complaints at a similar time implies there is something organised about it. How sad it would be if it comes from someone inside the model flying community.

When will people realise that freedom requires tolerance. If you are not tolerant of other peoples activities then in the end nobody will have any freedom.

Okay here's a good way to nip this in the Bud just incase the local authoritys
get a bit shirty...

Get a book or paper clip folder

A page for Every Club member

Name - Model - Engine - Prop size - front - rear - left - right


what you do is then take noise readings for every model in the Club following the BMFA Guidelines you'll find it in the handbook.

But at 7 Meters you take 4 noise readings for planes - Helicopters hover at 7 meters and its 3 sides. Planes have to rev engine full throttle and be held well.
Helicopters just have to hover. Jets/Turbines do not follow this rule.

Any council member who complains you get the book out and show them the noise readings in the book and it helps back you up

Note no reading is to be over 82db!!!! Anyone over 82db would need to change there prop and pipe to get the model in.

If you've done this, what sort of figures are you getting on heli's and what setup are the heli's. It would be helpful to know what exhausts match with particular engines to meet the noise regs. Maybe someone with equipment could produce a database so we could protect the more noise sensative sites.

Get one of these..

Digital Sound Level Meter > Maplin

I do beleive there might be noise measuring equipment available to borrow from the BMFA?

Heli's are generally quieter than planes

But off the top of my head a 600n with hyper/MP5/Hatori turning radix 600's

79db ish at 7 meters - remember you just hover anyway

Predator Gasser 26cc turning 710 rotortecs is 82db basic muffler as well

Not seen a heli fail yet, planes fail all the time and need tweeking....

spent alot of time sunday doing all of this we even purchased our own sound level meter,then followed the bmfa guide lines for operation,every heli passed except one.!----------- rappy 50 with a zimmerman pipe measured at 84db we dont know why it was louder than a 90 size but looking into that as we speak,prob is at hovering level at our field like possibly most others surrounded by hedge rows /trees etc the noise would not carry unlike a heli flying 3d at say 150 ft high,so that needs to be considered.we even tested all helis in idle up at hovering level.

What headspeed was it running? if it is just a hovering measurement can you not lower the headspeed to make the engine rev lower and hopefully produce less "noise".

you need to do it with the wind side on. to the meter not have the meter down wind. Also make sure the heli is skids at eye level but you probably already know all this

what was the raptors head speed ? and the engine was it and blades ?

Our club in very rural Warwickshire has had a problem resulting in IC flying being restricted to Fridays and Saturdays only. The club has operated from this site for many years but thanks to one individual home owner with lots of money to spend on baristers we had to agree or risk facing a total ban when our planning permission comes up for renewal shortly. Electric models are now becomming far more popular in this locality!

I'm suprised to hear that a zimmerman muffler was too loud - they are usually very quiet!
I'm lucky in that we don't have noise issues at my club and can fly anytime we want.
Sorry for your hassles!
Cheers,
Rob

south staff club,,,,,
i have attended the club which is in the middle of no where,,but i was once down there(the south staffs heli club that is) and i could hear someone flying a plane(a magnum actually)from the plane club at penkridge a few mile away.i think maybe that the noise is from there not yourselves,even tho the finger is pointing at you..if i heard them at the heli club then maybe the local can also
