Default Huh?

Andy,
What does this mean?

"If only MT would support their Fixed Pitch propellers with engines equipped with dual EI we would all be home free!

I believe Jim Ayres is looking into the problem with Bart at AeroSport power so a solution may be on the horizon."

I just reviewed all of the paperwork that came with my wood/composite MT fixed pitch and the only operating limitation I see is overspeed. Please clarify.

Default MT Fixed Pitch Propellers and Dual EI?

Hi Brian,
Whilst getting my plans for engine and Propeller packages sorted out for my -4 I was informed by MT that they would no longer sell their FP propellers to users of dual ignition, apparently due to warranty issues!
I spoke to Jim Ayres who kindly took up the problem as an interface with MT.

These are the two responses from MT :-

" in general we sold for the standard engine our 2 bladed wooden fixed pitch prop with diameter of 170cm, type: MT 170 R 185-3E.
As you have dual electonic ignition we will not use the fixed pitch prop as we had some trouble with a customer in the past.
If you like to go with electric constant speed propeller we would be able to offer you a prop, our MTV-18-C/180-57.

Sorry for the negative answer and we hope on your understanding.
Any further question please let us know."




"we sold so far only to the standard engines without dual electronic
ignition, at least that is what we got as information.
We had one customer who clear told us that he has such installation and we
tried the prop. Result was that we returned money and he bought Sensenich
prop. We tried it but it has not worked out.

If it was a problem only with his installation I can't say but we simply do
not want to upset you or others and therefore engineering decided not to
sell to dual electronic ignition.

I will copy engineeering again and we will see if they have different idea
but for now I must clear say not possible.

The electric constant speed prop will give you best performance from take
off till cruise and in case you do some acrobatics you could switch control
unit to manual mode and have a kind of fixed pitch with certain pitch.

Keep you informed

Eric Greindl"

With the advances in recent years of EI I cannot believe that I would be the only 0-320 user looking to use Dual EI (Pmag) AND an MT natural composite FP propeller. For me it would be the ideal partnership!

I hope this throws some light on question.Perhaps Jim will chime in with an update.

I have done it successfully. They will reward you with excellent fuel distribution and lower fuel burn but it took quite an effort in engineering and experimentation to get it to work.

I also have one on a O-360, I also had to make some changes with thanks to rocketbob for the help. My previous threads:

https://vansairforce.net/community/s...d.php?t=163055

Once I had it set up it has run great. Smooth, can lean till the engine stops without ever being significantly rough. Also works just fine upside down, which is what I got it for.

Default TBI

I have both an Ellison and a Rotec TBI. I may sell the Ellison or trade some parts. I havenít attempted the install yet but have installed one on a smaller continental engine. Not terribly difficult but if you need Paul C. For anything, expect delays.
I believe both are excellent units.

Are these units a fairly straight drop-in replacement for a carb or would airbox and cowl modifications typically be required?

bifft & rocketbob thanks for the short feedback and above all the links!
Plentiful info in those, thanks for all the experimenting you did Bob

Had been wondering for sometime as to why those TBI were not more popular. Some good answers found in the threads...

PS
My initial use of the search engine was not good enough...

Question ELLISON TBI

To Flyboyedwards

''I have both an Ellison''

Which model do you have or will it fit an 0-320 Lycoming 160hp.

If you decide to sell it or parts of it, I will be interested as a spare....

Thanks

Still wondering in this. I may need to change carbs and for the price the rotec is an attractive option.
