MT 03

[Bazza]

Hi all,

Does anyone know much about these MT 03's.
I'm considering having a test fly in one at Willies , maybe even buy one.

They would have to be reeel good cos theyre so bloody exy.
Does anyone know someone who's got one ?

I'm not being much help bazza but here's a link to a couple of photos (http://www.rotorcraft.com.au/smf/cpg/thumbnails.php?album=73) in the Gallery.

And here's a link to their SITE (http://www.gyro-copter.de/)

I'm no help either but the MT3, the Spanish ELA and the Magni seem to be copies of each other and from what I have read, they all are fairly safe, fly well but they are very expensive. I personally don't think much of the bob sled seating arrangement but I think it helps them keep the gyro reasonably stable so its one way around the stability thing.

The alternatives at the moment are the D7 of the skies, the Sparrow Hawk,then there is the RAF, the Firebird is coming.......coming ....you can save a lot of money and buy a Rosco 2 seater, least its Ozz made and you get 24 /7 service and all parts have many thousands of hours proven flying. not too many gyro makers can offer that !!if any. :yes:

This is a link to the origanal desiner of the Magni, and the other off shoots.
He will sell you a set of planes for around $150.00 if you send him an e-mail.

The MT-03 is just a Spanish ELA with a few plastic modes and certified in Germany.
The biggest difference between the Magni and ELA/MT-03 is the Magni is made of 4130, were as the ELA & MT-03 is made of Stainless steel. As fare as I know, S/S is not a certified metal for use in aircraft construction.

Sam,

Team America ... fk yeah!

Agree with you wildly on this after having some s/s components fail, it is a brittle material and would warn against its use.

Cheers,

Nick.

The MT-03 is certified to section T in the UK, one of very few gyros to meet section T as it is the toughest standard in the world. I can't see the UK CAA certifing anything that was not OK.

I have never believed in SS myself BUT there are apparently a lot of grades of SS,. the same as with alloys and steel.

Sam, I think that what we heard that day about SS may be just one persons views. I would really like to know the truth about SS.

Aussie Paul. :wave:

[Bazza]

I thank you all for your input and views, I myself being a welding inspector know a little bit about different matterials but I don't know of any malliable ss.

I will be looking into this further but I guess these blokes have done their homework.

Paul I have enquired about the S/S ELA and below was a quote I received back from a Magni agent.
"I am told that the airframe is manufactured from 304 stainless steel. I don't know of any other aircraft that has an airframe manufactured from 304.
The properties look fine on paper, the problems arise from the cold drawing process as consistency in material thickness cannot be guarenteed. Further welding the joints can result in extensive weakening of the material at the weld."
Regardless of the above, I do like the look and finish of the ELA, even more than the Magni, but as to the truth of using S/S in such a machine, well "time will only tell"

Sam............ :paper:

[Brian]

Thanks Sam, its interesting why anyone would want to use SS why alloy has done the job pretty well. There cant have been any SS failures as we would have heard about it by now and the ELA and MT's would have a a few hours up now.

I would like to see someone justify why you need to spend so much money on these bob sleds??

After looking at some of my welds, :redface: I'm not keen on welded airframes, particularly in gyro's where there can be a bit of vibration.

[SamL]

Brian, here is a pic of some of the welding on the s/s mast of a MT-03.

Sam..........

[russ]

There's alloys and there's alloys........each has it's own charactoristics......same goes for ALL metals.........ie....stainless steel

These machines wouldn't be flying 2 up here in Oz if asra deemed them to be suspect.

just my 2 bobs worth.... :blowme:

Can anyone advise me as to whether having a self latching throttle is a good idea or not?

In the case of emergency one may need to turn the tap down in a hurry and its one more thing which can cause some pilot pressure.

[Brian]

Thanks Sam for the photo, looks like quality welding and workmanship!
A question, is that vertical shaft the pre rotator ??

I'm not saying SS is suspect, I'm curious why they chose SS over alloy.

Cant say I would ask or want a 'self latching throttle', a friction lock is better IMHO as you can set it too a tension that is easily overridden.

That would be the brakes Drifter. It is on the Magni I have flown. :yes:

[Bazza]

Gee, I thought the welding looked a bit agricultural. :blink:

[Brian]

Gee, I thought the welding looked a bit agricultural. :blink:


I was comparing it with my welding! :(

[Sky Gazer]

Gee, I thought the welding looked a bit agricultural. :blink:


I'd have to agree with you on that one Bazza the Tabs for the pivot section and the seem weld for the main shaft were obviously not done by the same "robot" that did the ends for the rose joints.

[Drifter]

Are you sure Aussie? The site where I got the pic from seems to indicate its a throttle setup?

[Aussie_Paul]

The throttle and brake are on the same lever. I believe the one with the rachet is the brake. :yes:

Aussie Paul. :yes:

[Aussie_Paul]

Part names.

Aussie Paul. :wave:

[Drifter]

I understand this is from the Magni, but I believe that we are discussing the MT-03 here.

Fair enough. I doubt that anyone would design a locking throttle when you can have a friction throttle arrangement!!!!

To your original question. NO, NOT A GOOD IDEA TO HAVE A LOCKING THROTTLE. :shrug_no:

Well thought I might do a translation on the photo description from their site:

additional hand gas expensive lever for rear seat, particularly for the school enterprise

So doesn't really tell us much other than it's not necessarily for the student and is more for the instructor.

[Brian]

I though instructors only needed a bit of 3/4 pipe about 2 foot long !! Perhaps those bob sled things need a bit of linger pipe. :Bat1: :Bat1:

[rotor]

I think echo suggested a bit of 4x2 .. still same result :yes:

[MechFx]

My understanding is the smaller of the two levers is definately the brake. The rack and pawl is to lock it as a handbrake. in the above pics you can just see the top of the small hydraulic (master) cylinder that is operated by this lever.
cheers

You may well be right. The pic as posted may have been in the wrong part on the web site.
