Would anyone like to share their experiences with this engine. I'm trying to decide between the O.S. 1.40 RX and 3m 140. Comment would be appreciated.

I have both and they are both great engines, I think the OS has just a little more power, but don't have maybe 15 flights on the 3M I would say first how heavy a plane you useing these on, mine are both on right at 11 Lb planes, you can't go wrong with either, the OS cost a little more, so if your plane is 10 1/2 lbs. don't think you will see any difference.

The Mintor is lighter then the O.S. so power to weight ratio is better. THe Mintor comes with a header so price goes to the Mintor. The 1.70 weights the same as the O.S. 1.40 and has 17% more c.c.'s but cost a little more, again includes a header. Put a Mintor head on an O.S. and you have similar engines.
Not enough of these out there with much fuel through them so time will tell. I have yet to get my 3M 1.70 in an airplane. My O.S. is running so good. But when I do... the nice thing about the two Mintors is they will bolt right in where the O.S was.

go here to see the engine and my mount I made to clear the header

Hi,

At this time I am looking to buy a new 2 stroke engine.( I actually use a OS160FX with a cline regulator. on an evolis XXL)

Does the 3M mintor 140 have the same ball-bearing problem has the OS 140RX?

Does the 3M mintor 140 can run with less nitro ( between 0 and 5 %)?

What do you think about this engine?

thanks for your help.

I am running 10% Magnum blend in my 1.70. turns a 17x13 APC at 8250. A very healthy engine. The 1.70 has dual bearings and I am not sure about the 1.40 version. You can ask Lance at
www.aeroslave.com he is a distributor and warranty agent in the states here.

Hello everyone,

Thanks,

the 3M 170 is $40 more is it worth it?.........does it run like a OS?
i also would like to know the fule consumtion of the 170.......i know a guy that changed back to os (for what reson do you think) i am going to buy a wide body plane and build it over the winter......do you think that the wide body needs the 170?

Its like they say... "There aint no substitute for cubic inchs(cc's in our case)"

Why not? If the 1.70 is the same retro fit as an OS 1.40 try it. Unlimited vertical. and on windy days it will pull like a draft horse.
Always seems to be wind at a contest, at least the ones I go to.

Hi Julien,

I was lucky to be in touch with the makers of the 3M model engines for a while, and even got the possibility to visit their facility near Bergamo, Italy.

From what they told me, the "ball-bearing" problem known to OS should not be an issue with the Mintor since the complete engine is carved from full aluminium and not fused in a mold. The computer-driven machine carves the aluminium with incredible precision (1/100 mm). Both slots where the ball-bearings are installed are carved out at the same time using the same reference - they are thus perfectly central.

Yet, for a definitive judgement I'd wait until someone reports us about their experience with the engine.


As far as I know: No. Mintor reccomends at least 15% nitro in the fuel, altough friends of mine report that 10% ought to be enough.

Edit: one thing the owners of Mintor told me is that they guarantee excellent power and long life of the engine ONLY with their equipment. They had a lot of customers complaining the engine is not behaving well just to see them use it with worn-out spark plugs, wrong mufflers, or way too small props. Follow their advice, and the engine will behave perfectly, that's what they told me. I guess they should know about that... (edit end)

Hi Neo02,

Maybe you know the fuel consumption for the 3M mintor 1.70.
And do you know about there service (warranty).
For example if the engine need a maintenance , you can sent it
to an distributor for the maintenance . (for example like the YS
services).

Thanks,

Hi Thomas,

I'm unaware of service plans outside the main factory in Bergamo, Italy (which is about 100km from where I live). I know of a buddy modeller who had some minor problems with his engine and was able to arrange a meeting with the owners at their production facility.

Of course, while this might be practical for us living near the factory, it is of no use to most of you guys.

If I were you I'd send an e-mail to them, their internet site has all the contact information you need: http://www.mintor3m.it/. E-Mail is [email protected] .

As for the fuel consumption of the 170, I know nothing but my guess is that it will need ca. 15-20% more fuel than the 140 due to the increased size and higher power.

Hi raptor,

what they told me is that the engine runs great instantly with their pipe (both alu and carbon are great and designed specifically for the Mintor). If you want to use another pipe, they cannot guarantee that you won't run into trouble setting the whole power plant up. They say it will eventually work, but if not it's not the engine's fault.

I personally plan to install a Greve pipe due to long-time acquaintance with Mr Greve (both father and son), their OS pipe works alright with the 140 but - reportedly - has some problems with the 170.

Hi Neo02,

If I could send it to the main factory in Italy, no problem; because I live
In Aruba (an island in front of the coast of Venezuela) and either in the US
or Italy I have to ship it out.
So that would not bother me, because if they can do the service (warranty)
for people out side Italy will be great.



As for the fuel consumption of the 170, I know nothing but my guess is that it will need ca. 15-20% more fuel than the 140 due to the increased size and higher power.



And how is the fuel consumption 3M mintor 1.40 ??
Or if you don’t know that can you compare it to the YS 1.40 DZ
How les or more ???

Thanks,

Hi,
Has anyone tried to use another carb. (such as os 1.40 or 1.60 fx carb) in mintor 1.40 in order to use lower nitro?
