meeker mount is rated for a max weight ( can't remember what it is) this should make getting approval for any load a bit easier. Not sure if you could mount anything of any size further fwd on the 120 and still stay in CG limits .

mjb: we have a faa approved mount available for the ec-120. the mount is installed on the left hand side of the airframe onto existing hardpoints.
1) certified for payloads to 125lbs
2) qualified payloads include all popular models of cameras including ultramedia
3) compatible with cargo swing
4) easily removed and installed on mutliple airframes
5) intial install approx 6 hrs, field removal / install in about 5 minutes
6) currently in service on 20+ airframes

you can see a good series of pictures of the mount on our website www.meekeraviation.com
thanks

Thanks!

Is it out of the question to put 45 kilos on the nose in a EC120?
Vacant front passenger seat do it?
Would a weight like the big spacecam brackets have help balance things out?


Hang the director from the boom is often an attractive option:)

mjb: no you could put a camera on the nose, however you would have to bend the tube upwards to retain ground clearance, 120's are known to rub there noses in the dirt now and again. also you would need to relocate the pitot static as the gimbal would shadow the existing location. an aft counterbalance would probably be required. all that said and the very limited market for that type of install would just say go with side mount and narrow the focus down, not the best camera location for your style of work but proven certified alternative

Have you seen : http://www.cineflex.com/ ??

There's also the possibility of mounting it beneath the rear cargo door:

Hi RotorDompteur,

that mount looks pretty need, I like it. Any problems with that mount being installed in the rear as far as a "blurred image" is concerned due to the exhaust gases???

Greetings,

Frank

at my last job the boss man ( chopperdr knows who i mean) wanted to develop a deployable camera mount where after take off the camera would descend below skid height to give an uninterupted 360 deg view , the technical problems and failure modes made it a non starter .

chopperdr 8th October 2004 14:49

widgeon: easy on the boss man, he may be reading this. besides without him we would not have left hand drive in the astar.
sold another 120 side mount, now have 22 in service. not sure how the bp's aircraft are to be configured, but will do our best to help if we can.

Spunk;

I have only heard about it as a concern - but have not experienced it myself. Not even at fairly slow forward speeds...
But I cannot say that it won't ever happen.

Camera operators tends to like the mount as it gives almost unobstructed 360 degrees view.

Spare door for an EC120
 
We are considering a project which requires that we have an extra LH front door for our EC120.

But how on earth do you get hold of such...?!? :confused:
Have considered to track partially crached machines, but have found it to be difficult.

If you ask Eurocopter, they come up with approximately the same price as they charge for a whole new helicopter...

Any ideas would be appreciated...! :ok:

how is your chinese ?. If this is part of the Harbin workshare you could probably get one from them that fell off the back of a lorry nudge nudge . They are asembling them in OZ too maybe try there . Probably be cheaper to take a splash of the door and reverse engineer a carbon fibre one. The hinges and latches are not that expensive,

spotter or dollly for an ec120
 
just seeing what is available.

input into maintaining an EC120

thanks

Eagle 31:

Nice ship!! Now I understand your empty weight!

Back to our T&B: Never happened, when we did the T&B runs it turned out to be right where it is supposed to be! Nr is slightly on the upper edge, but it runs really smooth now!

What I don't understand is the W&B issues here! I never have a problem, though I use the rather short lap belt in the frontseat to confine really heavy pax to rear-center with the excuse, that they HAVE to wear the seat belt.........;)


RotorDomteur,
what's this project for the 2nd frontdoor ? :=
Curiousity hits the cat!

Do you have to stay 100% legal or is there some leeway for "special" jobs where you fly?
(E.g. ther is no kit to put a Tylor-camara mount into a EC120, but we still made it fit, without doing any permanent modifications and it worked the charm - as it was not permanently mounted it was "special cargo" :O :O )
..but of course that depends how much the local authorities will "help" by "translating" the rules into "understandable terms"

The VEMD never lies
 
After shut down the other day, saw the dreaded "OVER LIMIT DETECTED".
The VEMD says the NR was 460. This certainly did not happen. It is also not the first time this has happend. Have had this message come up a few times, all showing high NR.
Has anyone else had a similar occurence?

Alfa Hotel 2nd November 2004 09:43

This Nr overlimit sometimes occurs when you fly over or near very strong radiotransmitters.
Try and think where you flew the time that you had an overlimit and next time you fly the same route keep an eye on the Nr/Nf gauge and you will notice that it will respond erratically without the actual Nr changing physically.:ok:

helitubby 2nd November 2004 15:09

NR Overlimit
 
Thanks for that. Will keep a lookout.
Cant say there are any big transmitters around.
We fly pretty much the same route all the time (scenic flights) and it only happens occasionally, but I will try to look for the trend or to see the gauge fluctuate.

Sounds like a great question for the forthcoming meet-and-greets with the Eurocopter guys from France in SA.

Check posting on rolling EC120 in African Aviation for number to call to book yourself a ring side seat.

What I did forget to mention is that the weather can have some effect on it as well.

In the past I found out that it was a radio transmitter caussing the Nr overlimit and ended up flying in an arc some distance away from it. However on some occassions due to a weather change the Nr overlimit would still occur on this diversion as well.

How long have you been flying the ec 120?
