RE: EME new engines, 35,60 & 120 twin
 

i hear you on the prop bolt pattern.i wish all engines had the same set up,the 60 has the same pattern as DLE,DA so that works for me.
also glad to hear that the engine is a true 60,thanks for the info.
i just half to say how much i like the Falcon 24-9 despite the lower rpm's,the engine is smoother the prop has a lot less noise.i think the plane is faster and has a fast vertical climb,pullouts are strong,good throttle response.
this is the first prop that i tried that gave me a lower rpm that i like better.

RE: EME new engines, 35,60 & 120 twin
 

cheers for the info bananaman thats good to hear. I will be watching this one as others try different props. If the 60 can swing a 24 prop at the same rpm as a 55 can swing a 23 I may also end up being a eme test pilot.<br type="_moz" />

RE: EME new engines, 35,60 & 120 twin
 

we got in one of every engine to try as we are setting up



to sell them. the 120 i have has the same boltnpatten as a da 100. dle 111

RE: EME new engines, 35,60 & 120 twin
 

Falcon props are the bomb !!

RE: EME new engines, 35,60 & 120 twin
 

Some weights for the EME120. Bare motor (no ign) plus plugs = 83.3oz (2363g), mufflers (pair) 5.8oz (164g). Plugs are EME brand, ign is Rcxl.

RE: EME new engines, 35,60 & 120 twin
 

Taildragger21 - Your EME 120 has the same bolt pattern as a DA 100? My EME 120 is NOT the same as my DA 100, the holes are spread further apart. I believe the EME 120 holes are the same as the DA 150. I recommend you double check this so you can be sure the information on your engines are correct.

Ramoooo - Three days of rain and wind here.. :( No flying

RE: EME new engines, 35,60 & 120 twin
 

I can confirm mine does NOT have the DA/DLE 100/120/111 prop bolt pattern, which is a bummer as I drilled a new prop as another spare for my DA120 just recently.
Didn't get to set up the EME and run yesterday but might find time today.

RE: EME new engines, 35,60 & 120 twin
 

Steve. Iwill double check again and confirm but I am pretty sure mine has the da100 pattern.
I just got 3 last week to evaluate direct from EME,, We are setting up as a dealer in the USA. I will make mention of this issue to the owner and let you guys know.

RE: EME new engines, 35,60 & 120 twin
 

Ok guys.. I stand corrected. The 120 has a 150/170 bolt pattern.. I have spoke with EME tonight about changing this. It may take time but we shall get it done

RE: EME new engines, 35,60 & 120 twin
 

Great, I was hoping to get 2 of those for my self if they turn out to be good. at least now you can cycle between proprs if you have DLE or DA.
I hope they get it done.

Taildragger I sent you a regular e-mail about the EME and wires when ever you have time.
thanks for the support

RE: EME new engines, 35,60 & 120 twin
 

ramoooo,
Sorry I havent responded yet.. Getting ready too.. I have been BUSY for a sunday night.
Just had a 2 hour call conversation with the EME factory about the engines and about the 120 bolt pattern..
Guy these engines are proving to be china's finest. I will release some data from a friend that dyno'd and quality tested/ran the 60 and 120.
I will also say no more as I cant but there is a LARGE future with Taildragger RC and EME on producing an even better product that will be untouchable to compete with..
Thanks!

RE: EME new engines, 35,60 & 120 twin
 

As quoted from Aussie steve per my PM..

"Overall I think the EME's are a good choice. The engines themself are good performers and they are as well built as anything coming form China. The cranks come from the exact same supplier as the DLE cranks . (The major parts are not interchangeable though)

The other thing they have got right is where most Chinese engines fail. They have learnt from their mistakes on earlier offerings and have rectified them. They also seem to be following up with good support for their distributors.


I have been bench testing the EME 60 and 120 (I haven't got my hands on a 35 yet but will do shortly) that I purchased through a dealer here. He didn't realise it was me getting them and he nearly died when he found out. In his words "If I knew that, I would have gone right through the engine first" - Exactly what I didn't want to happen.

I didn't find any major problems. The inside of the crankcase was clean, the bolts were adequately torqued. The timing was a little more advanced than I like to see (it was 35 degrees) but not terribly so. The carb needles were a little lean (about 1 1/4 turn open) than I like to see from a factory but were probably at about the right spot.

I now have about 2 gallons through the 60 and about 3 through the 120 and they keep getting stronger.

I have also flown a 60 and an MVVS 58 powering identical airframes. (The seller here was also a Flight Models dealer who got some EG MXSR's in) The airframe was the EG MSXR. Both engines were choked by the exhaust as both were using the MT CS65 Canister / flex header in them and neither is optimised for power. However the EME 60 keeps up with the MVVS 58 with ease. Perhaps with optimised exhausts the MVVS would be a little higher in power but not a lot.


I think you are on a winner with this brand.

Steve"



From another thread..........

I have been doing some testing of the current version EME 60 and the EME 120 for a couple of people. This testing is being done on my Dyno (not by XXX prop at YYY RPM but a real dyno that plots torque produced). The EME's do NOT produce more power than the DA's (and no - I am not a DA fanboy by any stretch of the imagination) but they are not far behind.

The EME are currently one of the better value for money products out there (In the size range, DLE remains the current best among the budget choices).
The EME 60 power band is close to a DA 60 (slightly less), the mid range torque curve is only a little behind the 3W 55 and on par with the DA 60 and the general construction is as good as anything seen from China to date.

The EME 120 way overpowers the JC 120 right through the torque curve, it sits close to the DLE 111 in the mid range (slightly higher in the upper end of the mid range) and is slightly less than the DA 120 in the top range.

Would I buy an EME for myself? - no - because I buy no engines from China nowadays.
Would I place them as a reasonable choice for a budget engine? - yes.


KEEP IN MIND. Steve is not affliated with hyping the engines for us. This last paragreaph he posted here before he even knew we weere involved. SO his evaluations are totally unbiased.

<p class="MsoNormal" style="margin: 0in 0in 10pt"><span style="line-height: 115%; font-family: "><font size="2">That pretty cool Taildragger. Hopefully <span style="mso-spacerun: yes"></span>they listen to you and change the bolt pattern cause it makes no sense to have it similar to the 150-170cc.

Maybe DA will have a challenger after all.
I really don&rsquo;t care for any brand as long as they are reliable and save me money.

By the way , Arizona flyer just got an EME 120 and I'm really anxious to hear from him (once the weather clears out) I live in the bay area and its been bad weather here for the past 2 weeks and looks like this coming week too, so no flying for me either

I'm looking forward to getting 2x EME120 in a couple of month if they turn out to be good. thats 2 for the price of 1 DA with mufflers. </font></span>

RE: EME new engines, 35,60 & 120 twin
 

Yup for sure.. I am building my new 36% sbach and mounting my eme 120..So I should have data soon.
We also sent a 60 to one of our sponsored pilots and he will definatly be wringing it out as he flys 3 times a week. plus he is in florida so he will be running and flying it by next weekend!

RE: EME new engines, 35,60 & 120 twin
 

Ok guys.
Got the eme 120 mounted. Just gotta finish the sbach up..
There is plenty of room in the cowl as the width is no larger than the 100's and 111's..
I can say this engine is lighter. Not in the 120 range lighter but more so than the 100's and 111's

RE: EME new engines, 35,60 & 120 twin
 

man that was fast.
you couldnt resist could you  ? lol.

nice looking plane Taildragger. all the best on the maiden. and looking forward to the report

RE: EME new engines, 35,60 & 120 twin
 

hanks ramooo!
This is sbach #3.. I love them

RE: EME new engines, 35,60 & 120 twin
 

Got a chance to run a tank through the EME 120 this evening. I intended to fly but I couldn't get a consistent idle so I opted to run a few more tanks. It seems like the timing is a little advanced because it likes to pop before you get all the way through TDC when starting and sometimes misfires through the carb. Also it dropped a cylinder when idling around 2000 RPM so I am not sure what is going on just yet. I am at 4700' elevation so keep this in mind, however I was getting 5600 RPM from a Menz 28x12. I would have liked to see 5800 to 6000 but I am not expecting much from the first tank. I can say it pulls like a truck and I can't wait to get her in the air to see how much. It's too early to give a good review yet so just consider this an update for now. I am at 1 and 1/2 turns for both H and L now.

RE: EME new engines, 35,60 & 120 twin
 

you have to time the engine,they are set at 35* from factory.mine had a small mark on the case where the edge of the sensor bracket lined up.i have not ever bought a china engine that was set at 28*,they seem to like them around 35*for some reason.

RE: EME new engines, 35,60 & 120 twin
 

That is great feedback. How do you find the total degrees? With a regular degree wheel?

RE: EME new engines, 35,60 & 120 twin
 

With a set of calipers.

RE: EME new engines, 35,60 & 120 twin
 

Thanks Milton! I will check the timing tonight and report what I find.

RE: EME new engines, 35,60 & 120 twin
 

Milton is the man!:D

RE: EME new engines, 35,60 & 120 twin
 

just goes to show ya what a good old southern boy can do...thanks Milton gonna do it to my 60. Had planned on it all along but just have not taken the time. The engine runs very well but backfires and misfires when trying to start it, even after its warm form the first run...;)
