I am looking for an engine for my Chip Hyde double vision wich I have flown with a DA-50r but I flet that it need just a little more power. Do you think the MT 57 will give a bit more power? I figure the dl is about on par with the DA.

Time will tell there should be some flight reports soon.

I have both, the MT57 is more powerful, it's on par with my Brillelli 60cc 366GT. I did a test you can find here on RCU with the engine having less than an hour on it and my limited tuning skills. The test reports 30 pounds of thrust is probably low, it was sitting a little uphill, facing into a 20mph wind, on grass, it was really bad out, otherwise there would have been a flight report. Next time I test it, it will be calmer and on flat asphalt, I think I will get another 3~4 pounds of thrust.

I'm thinking of getting another one to put in my 94" Extra which is a 80cc size plane, if it preforms well in my 21 1/2 pound 87" Yak. It 's $390 until the end of the month, then it goes to $430, I think LS Pro Larry said he had four left in this shipment. I got the Yak from a friend that had a DA in it, it just hovered with no pull out, with 33 pounds of thrust it should have pullout with a 21 pound plane. Put this in a 16 pound plane you're going to have 2:1 power to weight. This engine should be compared to the DA and Brillelli for quality, not the DL, it's in a totally different class.

How the heck do you get an 87" Yak up to 21.5 pounds [X(] The DA doesnt have 33 pounds of thrust closer to 26-28 depending on prop.

I don't care what 57-65cc motor it is.. you aren't 3Ding a 22 pound plane.. with a pipe you might have ok pull out.. you would also be adding weight so its hard to say.

As far as the original question.. the 57 looks nicer than the DL and appears to have more power. Hard to say at this point. Personally I don't see all the hype of the DL, played with 2 now and seen several run. the 57 looks to be a good engine, won't know till someone actually puts some time on one. Need someone to go abuse it for 25-40 gallons and see how it holds up

It's really a stoutly built Yak, it's the Lanier 87", I just got two 94" Lanier's that should be 20 1/2 pounds. I also put really big battries in it, two 2400 6v nicads, and it's a 4 servo wing,. It's the same size as my Sukhoi with the Brillelli 60cc, just 5 pounds heavier. Hey I was new to 3D, what did I knw. I just put the MT57 in it to get the MT57 in the air, and I didn't want to pull the Brillelli, but I thought about it!.

you and i are thinking alike.that is where the MT 57 is going when the next batch arrives.
my DV needs more ump also. the DA is ok but no where near 2-1 thrust ratio.

Take this for what you may.......... I've known Larry for 35 years he's a friend, just so you know.

I just ordered my second MT57cn from LS Pro. He's got a shipment due the beginning of the month, it's almost all sold out, there might be 5 unspoken for, so if you want one soon don't wait. This engine will make LS Pro.

From LS Pro I've got:
1 100cc twin....power of a good 80cc, weight of a 100cc, a fine scale engine, not what you want for 3D, but I'm putting one in a 94" Edge 80cc.

2 50cc twins.....Great motor, not a 3 D'er but one of my favorite motors, one in my G-BRIT, ones going in a 120 inch Zlin 120 scale ship I'm going to make.

2 50cc GR Pro the first one I bought, ran fine, just didn't make much power, I put a canister on it an broke the mounting lugs, Larry @ LS Pro gave me a new engine, I broke those lugs, so I gave it back to him, Alfonso Wang gave me a replacement engine free, it blew up on the second or third flight. Larry stopped importing those engines.

6 MtT62 I need one, but got the importers price, because Larry didn't know if he wanted to import them. What can I say a G-62 with electronic ignition, good power, lightweight, the most bang for the buck. I have a few spares, you want one $300 it's yours.

1 MT50 A sweet engine, not DA or DL power, but a beautiful well made motor, swings a 20 or 21x8 prop, quality motor good price.

1 and 1 on order MT57 a kick-ass motor, more power than the DA, DL, TOC, without a doubt in my mind better than those. Larry doesn't have to make any excuses for this motor, it will hold it's own against DA, 3W, and Brillelli 3666GT. The Brillelli is the closest competition to it. I have both the Brillelli 366GT(60cc) and the MT57, I think both are great engines, the Brillelli 366GT has a proven track record, Brillelli is acknowledged as the BEST customer service in the industry, and is American made. The MT57 is the new kid on the block, Larry has got Ralph Cunninham to sign on for any warranty work, the price is great, the engine puts out lots of power, and is quality built.

Well I jumped on board. Sent Larry some Paypal bucks. I am going to install this in a Lanier 94" Edge. I know the boys are installing 80cc ZDZ's that will hover it 3 clicks off idle but I'm strictly a Sunday flyer. Seems like the slower the plane flys the better my basic aerobatics look. I hope this motor will have just enough power. I'm sure I'll need some propeller advice too. The ad says "choice of 2 mufflers" do you get 2 mufflers with it??

Yea, I got the 94" Edge, I said $349, they can't get any cheaper, then they put the 94" Extra up for $299 I jumped on it. If they give away the 94" Yak I'll have to pass, no room!

I was thinking of putting the MT57 in one also, I ran test yesterday and got 30 1/2 pounds of thrust, results in another thread here on RCU. I think it was high than that, the plane was on grass, facing uphill, into a 20mph wind, they all hold the measured thrust down, I do more test in the future. I'll run a pipe on it, I bet I get close to 38 pounds of thrust. 30 Pounds of thrust will defiantly fly a 94" plane.

The muffler is an either or deal, you might ask him to throw the other kind in cheap, Larry will work with you, he wants these engines out there.[sm=thumbup.gif]

Thanks Rich for the info. I have watched your video, the Aussie's, and I think Tommy's run ups. Looks to be the next gen motor from Asia. Price, displacement and power combined with the Lanier closeouts makes it too irresistible to pass up. Can't wait to fire it up. From what I could tell one muffler is a slightly larger stamped metal and the other is slimmer cast aluminum? I don't have any info on them..

I have both, the round one is the same as the MT50's muffler, the flattish on is the one that comes with the MT62. I would have tested them to see which makes more power, but when I went to put the flatish one on the 5mm bolts that came with the engine's round muffler were about 5mm too long. Both are well made with tubes to put the bolts in rather than have real long bolts going through the muffler. I like the finish of the flatish one best, but I think you'll fine the roundish one may make more power. Larry said the outlet area is the same so he doesn't think one has the advantage over the other, the flatish one will work in a flat engine cowl better I think, in a round cowl it doest matter.

I put money down on my MT-57 today. I love the idea of a purpose built engine instead of a bunch of parts from differnet engines thrown together. With Ralph behind it, you just know it's going to be a killer.

How does the MT 62 compare to the MT 57 in power running characteristics weight, prop size etc.

I've got the MT 50, MT 57, and MT 62. Each is a little different:

The MT 50 is a sweet engine runs great doesn't have as much power as the others or the DA or DL, it may have the power of the 3M TOC 53. The 53 is probably the closest in power, smoothness, handling, but with a nice CNC crankcase and Ralph does Larry's warranty work, so you couldn't be in better hands.

The MT 57 MAY be the next "King of the hill", it has the beautiful CNC crankcase, huge gas passages in a purpose made cylinder, I did a prop test it's here on RCU check that out. I'm going to put a pipe on it, I got 7350 with the stock muffler, I expect 8500 with the pipe, what 7.5hp? But as of now I know it puts out more than a DA, DL, 3M, ZDZ, I got the same readings as I got with my Brillelli 60 366GT, which was/is my favorite engine, I really like the rear carb on the MT 57 though, it may be my new favorite.

MT 62 Probably the most bang for the buck, Ralph loves the G-62 and this motor, it needs Ralph's G10 carb rotating block, the stock block is too soft, usable but you have to be careful tightening the carb down, get the G10 block it's cheap. This engine has a case crankcase, better looking than the DL's, soup it up with a pipe it would probably make the same power as a MT57, it's actually a proven engine that has been made to make 7.5 hp. Stock I think the MT 57 makes a little more power.

Anyone of the engines are great, but so are DA, Brillelli, ZDZ, and I think the DL and 3M close.

All 3 weigh about the same, the MT 50 is better off with a 20 or 21 inch prop, the MT 57 and MT 62 swing 22 or 23 inch props.

Soarrich what kind of prop size and brand did you use because I did not get the kind of RPM you are describing. With a 22 X 8 (xoar) I got 1300~6800 RPM and 25 lbs of static thrust. On a 23 X 8 I got about 27 lbs of static thrust (could not measure RPM at the time).

soarrich

My Feedback: (98)

Prop idle max thrust in pounds and ounces.
Vess 23A 1800 7000 28 14
Vess 23B 1830 6570 18 13
Vess 22A 1950 7350 30 6
JXF 22x8 1900 7150 23 0
TBM 22x8 1700 6600 20 8
BME Lam 22 3D A 1740 6450 26 0
BME 22x10 Lam 1900 7150 22 4
Zinger Pro 22x6 2000 8000 24 8

In the video you'll see I was getting 7410 rpm that was with the Vess 22A. When I took the readings I tried to let the engine stabilize at a Max rpm, I didn't want to overstate rpms, that would just confuse people, I have no interest in selling the engines myself. After watching the video I realized that I have to be very careful to make sure the plane is lined up with the scale, and that the scale is taking the full load, even though the engine was turning 60 more rpm than I listed for the Vess 22a, I think the max thrust reading was max 29 pounds, it should have been higher than 30 6, and I think I remember it being a little off center, but I really wasn't taking readings or doing the test then, I just thought I would show how I did the test so others could repeat it if they wanted to.

I'm surprised that the Xoar 22x8 and the JXF 22x8are so different, I thought they where the same prop, and in test you got more thrust, I got more rpm. Another surprise was the Zinger, they are universally bad mouthed and yet it was middle of the pack in thrust, top in rpm, and I think it really spooled up quickly, I expected the last two , but not the good thrust readings.

On prop construction, the props where about the same in quality except for the Zinger, it's leading edge was 1/16 squared off, and so was the trailing edge, how it made the thrust it did is beyond me. The other props where pretty much what you would expect, except for the TBM, it is really a hunk of lumber almost twice as thick as the others at about four inches out from the hub.

Here's a video of me doing a test. http://www.youtube.com/v/KNSBJRF6Mus

Hmm, interesting results. You are right I got less RPM from you but more thrust. It could be that it was night and the tachometer was not reading well under the low light. I am going to have to try this again during the day to make sure. It seems thought that the Vess props tend to perform better. I am going to have to try one to see the difference. I wonder what would this engine do with a Mejlik prop? I think that I will try a 23 A Vess to see how it does.

I saw your video so I do not doubt you. What kind of prop was that? I noticed that you had some intermitted popping here and there. I had those too until I advanced the timing and then it went away.
