MW44 Status?

[DDragon]

It's a slow day and I thought I'd ask if anyone knows the status of the MW44 Helicopter turbine from Wren. I'm sure Sara will pop her head in... but I thought I read the someone on the forum actually got one recently? But I could be wrong.

Interested in one of these this year I think.

I have plans to install one in my Stratus and have allready drawn the part to replace the front "a" bracket to allow the engine to fit. Craig

I'm kicking around the idea of using it for a scale helicopter. I'd buy the turbine first and go from there.

I guess the people who know me well realise that there hasn't been any good news to give, because I've been quiet. If I've got any good news I'd be straight in!

I'm not going into great detail, but we have been very badly let down by a company who were working with us, making some of the most critical parts. The engine should have been ready before Christmas but they have given us "expected dates" then gone back on their word time and time again. The latest date was given us at the beginning of January "17th February" - yes folks, today! But last week they came up with ANOTHER change of date "Some time in April, perhaps". At that point, we'd had enough and cancelled the order.

However, as of an hour ago, there is better news. We have managed to re-source this work and providing the new company can do it right, the parts should be here within a reasonably short time. There are still a few "ifs" and "buts" but there's a glimmer of light on the horizon - and believe me, it was DARK out there last week. That's why I've been quiet ...

well sara if you need some one to test it, that way you know that if i cant break it no one else can

[Rainmaster]

will this do for now

[metalmagus]

Nice set up Rainmaster.

Thanks MM
I'm away for a few days but will post some more pics and a bit on the build when i get back.

that looks a lot like the TM conversion, very nice and very well built, its a shame some tried to spread unfounded rumours about its ability to not shake.
keep up the good work

[simon109]

Rainmaster, is that the 44 or 54 ?

I still can't decide if I should hang on for the 44 or just go with the tried and tested 54.

i think you will find it is Mw54, done by a skilled Wren turbine builder,

there was rumours it never got off the ground and shook itself to bits with vibrations, but after PBMdazza post it seems they were false..

Would love to have seen it, the Xcell spektra G was a nice machine... unsure if they still make it..

Sorry Mat, no it is'nt
This is a brand new airframe and turbine built since christmas.
Its only just been finished and is awaiting test flying, it was planed for next week but due to problems with my Gasser crashing on 35meg i am changing everything to 2.4.
The design was taken from the one you mentioned as its realy the only way to do a spectra.
The spec is.
New Spectra with tempest head
Wren 54
Conversion parts made by Ian Oddie
Remove before flight saddle tanks 2x 11oz, 14oz main tank, and air trap
9255s on cyclic
8700G tail
CSM 720 gyro
2x flight power EON 28 3750mah packs
Fromeco Sahara reg
710 SAB blades (but i have a minair 36" extended boom kit and 800blades to fit later)
and one of Chris's georgeous canopies (hope he does'nt mind)
I am new to Turbines and i have had a lot of advice and help from a very good turbine flyer who will hopefully be test flying it soon which should be cool.
I just hope it does'nt shake!!!

Sorry mat.
I missed the last bit of your post.
The spectra G is still going strong Its a very good air frame and will 3D easily as a gasser.
I have 2 as gassers the only problem i have is failures do to vibration I have had crystal fail, reciever fail, tail pushrod fail, tail bell crank fail all ending up on terra ferma!! I brick it every time it takes off but I am starting to sus it now if you balance and dial in everything engine related spot on and get the mixture right they dont vibrate any more than a nitro.
Now i know people will think its expensive flying X-cell but as a gasser for every 3 gallons i have about a £70 start on the nitro boys for crash parts so its not too bad, but if this 54 fly's ok i'll pup a 44 in the next one.

that looks a beast, and a really nice machine, i flew my xcell with a tempest FAi head, i loved the tempest head as you could make adjustments on it depending on what your flying style was.

The turbine will be very smooth, look forward to reading more about it, please keep posting if you get time, as it is nice to see another Wren conversion in the air..

Hi Mat
Yes i will.
At the moment i am trying to get my head round this bloody DSX9 thingy, i dont like it yet.
I have always used futaba, 9C super at the moment (i think like you) and to be honest i think it does more than the JR, little things like warning if you switch on in idle up,being able to assign most of the switches to anything.i run goveners on the gassers which on the 9C you can have on a switch on or off, i think you have to use the idle ups on the DXS9, and to top it off the switches are all in the wrong places i mean we all know throttle hold is top right front and idle up top left front thats just how it is.
On the JR they are on opposite sides.
I sure "someone" who fly's a DSX 12 will slate me for this He He.

[Matt Jenner]

i tried flying the Jr tx, the throttle hold is oposite to Futaba, and i could not assign a throttle cut, which was annoying, and to change a model i had to turn off the tx and hold the mode button and switch on where with futaba you can select model using the rotary dial, so i remained with my FF9 super, i also found with futaba if you had alock out it would come back quicker than a JR handset, thus giving you vital seconds to save your model, and we did a test to prove it...

I like the simplicity of a JR when using 4 servo CCPm, you have a diagram showing you where to plug int he servos, my fingers could also fit between the idles ups where as on FF9 it doesnt, but i have kept to my futaba, as i prefer it...

Good luck in your project, i love the big canopy of the bergen,

Matt

[WillJames]

If that DSX9 is like an X9303, you can assign the hold switch. I think you might also be able to have gyro on off on the gear switch if you slave your gyro gain to the Idle-up switch. Not 100% sure about the gain, but I know for sure you can assign the front switch on the upper right to be hold. It is in the system menu that you get to when you hold the menu button and turn on the TX. My TX is at a friends, but I think it is FNC menu it is definitely in the system menu on some screen.

I have had 3 Spektra G machines and they are a good airframe very capable of some hard 3D. Good choice.

[Rainmaster]

I think you're right Will but when assigned to the other side, the hold switch is a small one and i like a BIG hold switch, i tend to need it a lot LOL. Glad you like your Spectra's I just love my X-cells.
Matt
You're right switching off to change model "how bad's that", I though i would be able to assign the top right rear to throttle cut same as the 9C I'll be a bit pi***ed off if you cant.
Cant agree on the lockouts though on my Gassers if the 9C locks me out "which it does", it allways ends up in a crater!! Thats why i'm changing to 2.4.
The thing that gets me is i am so maticulous with my machines yet down at the field people are flying raptors etc with bits hanging off, batt packs held on with a rubber band, and wiring all over the place
And they never take their helis home in a carrier bag. "Its not fair"

Hey John,

You can your very own sticker now matey ;-)

In all honesty you will be able to setup your DSX9 to match everything that your 9C did, the only exception is the switch assignability is a little less than on the Futaba but you can switch the hold from the back left or back right toggle switch all ok.
Also there is a throttle cut on the 9XII/DSX9 but it has to be invoked through the power on menu from memory.

Once you get into the set you will find it a much more intuitive system than your previous trannys.
