Depending which LHS you purchase from, it is definietely one of the more well priced gas engine around. There are several authorized service centers in United States. If you are having issues that may be beyond that of your and your LHS expertise, please let us know. We'll put you in contact with your preferred authorized service center. One of rumor regarding 3MM is that the mfg name is a playing off of the 3W engine. So sorry to dispell some of the conspiracy theories, but it does make interesting topic. Again, visit www.3mmusa.com or www.3mmusa.com, and let us know how we can better serve you. Peace, Steven Chao, CERMARKNice to see my favorite electrical component manufacturer is handling them.Peace, Steven Chao, CERMARKWebsite link is dead. It is an excellent engine. The carb was a Walbro, so the carb kit is readily available online. Peace, Steven Chao, CERMARKI've got high expectations for this engine, I hope I'm not disappointedShame, for they are a good engine. CheersOk well forget that, I've learned the ignition module retards the timing somehow automatically for start up, so I guess I'm messing with something i shouldn't, guess thats just for the old magneto type ignition, or non automatic spark advancing box.Yea sounds crazy and dangerous but be super careful and have someone put the RPM Meter on it as you move it. But the movement will be just a tiny bit to get max rpms, Set mine that way because the peak RPMs don't lie. Oh and there not obsolete just not as plentiful but 3W Top end parts are the same Specs.

Forum questions or problems Test Posting Forum I was there when my flying buddy purchased this engine from Wild H. Hobbies. Hey, the engine ran very good back in the day.http://www.deloge-nt.fr/media/photo/4-speed-manual-transmission-ford.xml It became tired because in my opinion it was ran too lean a few times and it was overheated too many times due to using too big of a propeller and inadequately cooled. So, last year my friend sold this engine to me and now I have it. I would like to rebuild this engine. I see that the front and rear bearings are still available from Cermark along with a few gaskets. No seals-do I take out the old ones and measure them and see if my local bearing shop can match them up. Shouldn't someone out there in this big world still be servicing this engine. Does Bowman make a compression ring for this one. I am considering using this engine in a professionally built Walt Moucha Models PJ-295 that weighs 17 Lbs. If used I am planning to use a 22 x 8 or 21 X 10 propeller on it. If I do use this engine it will be completely rebuilt and restored to new condition and if not, I will just purchase a new engine such as the DLE 55, or a ZDZ or something that flies scale birds well. One would think that since there were so many of these made that there should be parts available. Is this a throw-away engine. Like a bic lighter? disposable? WHO HAS THESE PARTS!If they can't help try Scott Sorenson. I worked with him at DawghouseRC. We were the first to bring that motor over here to the US. Scott went out of business but might still have some parts.They used to have parts for that engine. They also used to have a metal reed valve block to rplace the plactic original part.I haven't stated it yet, but it has very good compression and looks to be in great shape. I also have the 3M TMM-106 twin that is brand new still in the box that I plan on installing in my Meister FW-190A swinging a 25X12 threebladed prop. I've seen several youtube videos of these engines in action on 3D aerobatic planes and although videos can be deceiving, I was quite impressed with the power and performance.PM with details of what engine you have and parts required.http://www.drupalitalia.org/node/67586 Bear in mind I'm in Australia, so shipping will be high. Cheers Grossy I was there when my flying buddy purchased this engine from Wild H. Hobbies. Hey, the engine ran very good back in the day. Like a bic lighter? disposable? WHO HAS THESE PARTS! It's a great motor, 3W knock off basically. I have not needed parts for mine and have run them several years now.He gets his motors and supplies from a guy in China who distributes the TMM motors and parts.They are no longer 3mm but are now called TMM. I talked to Tom over there and he confirmed it, yes they can get the parts for these motors!Use of this site indicates your consent to the Terms of Use. Use of this site indicates your consent to the Terms of Use. To say the least it was a task of some duration, but one that gave me special insight and understanding of not only gas engines but also propeller selection.I ran 87 octane (blended with ethanol) as that is what is available in this area. Each engine had one gallon of fuel run through it with the designated break-in prop. For the first three quarters of the gallon the engines were run no more than 10 minutes and then allowed to fully cool. During each 10-minute cycle the throttle was manipulated to make sure a variable RPM was achieved. Cylinder head temps were taken with an infrared temp sensor during the runs to make sure nothing was overheating. All starts were by hand. With the exception of the SPE-43cc engine I never touched the needle valves, but it was just too rich in the 100 degree air and 60 humidity to run well so I leaned that engine back very slightly to improve the run. All the engines were run with a 6 volt NiMH battery with a capacity of 1200 or greater mAh: the 3mm 50cc TOC was run with a 4.8 volt battery. The throttle was varied within each ten minute run multiple times. Starting was easy, and once I established a routine for choking, the process became very predictable. I found it necessary to choke all the engines before each start.http://apartments-ivica.com/images/3n71b-manual-valve-body.pdf I also found they started better if I cracked open the throttle just a bit to allow some air. After starting, I moved immediately to idle to allow for warm up. It is easier and safer if your flip is away from the engine and down. Periodically I would re-torque the prop to the hub. Early runs typically were full of vibration that settled out after a gallon or so and after I backed off the oil and adjusted the carburetor. Started in 1977 by Fred Jamieson, the Master Airscrew brand is well known among flyers worldwide. The fine people from Master Airscrew provided me some information I want to share with you regarding their line of propellers. The nine professionals working at Master Airscrew ensure, through their combined total of almost 100 years of service, that each and every prop leaving the shop is perfect, and I can confirm that claim. Their wooden props are imported from Italy. They offer a high quality prop at a good price and great customer service. Be on the lookout for their new line of Formula One Series propellers: they are sure to be a wonderful addition to an already excellent lineup. I used a drill press and set up a jig so I could make sure I centered the hub bolt. The prop washer helped me align the two secondary bolts. The props were then checked for balance. If needed, I sprayed clear acrylic paint to the light tip in layers to add weight. The Master Airscrew line of props was exceptional throughout the testing process. Wooden props require re-tightening after each run until the prop settles into the hub.This is important to make sure the stand does not rattle, vibrate or come apart. The fiberglass also keeps the fuel from softening the lite-ply. Surprisingly, you get very little fuel on the firewall with gassers. I mounted the stand to a large picnic table so that there was no chance of any movement. The stand was tall so a cable was connected to the stand and the picnic table with a fish scale in the middle. A second cable was attached to the stand to make sure nothing could move forward beyond the movement of the scale which proved very effective. The rich mixture and higher oil content just do not make the comparisons worth much. The break-in process is a necessity though.Both engines share the same firewall bolt pattern and the SPE 26, SPE 43 and MLD-28 share the same three-bolt prop hub pattern.I found no problems with any of the plugs. At press time the MLD-28 is being sold with a different CDI ignition and velocity stack as the MLD-28S. The SPE-46 was upgraded from the SPE-40. The SPE-43 is being shipped with a different timing setup and some slight internal modifications from the engine I tested. It is a blend of rough edged power and polished beauty. From the minute you open the box you can see this big brute is all about hauling a plane around wherever it wants to go. I enjoyed this one as much as the MLD-28. Of the four engines this is the first to pull fuel up through the crankcase and into the cylinder. The hub mount is also significantly different with no center bolt and six propeller bolts. The center of the prop shaft is drilled and tapped for a spinner. It required moving the throttle linkage, and there are no standoffs provided with this engine. You will need to provide either an engine box or standoffs to allow for air circulation. When I did the bench tests I did not stand off the engine but never got over 170 degrees of head temp with crankcase temperatures right at 100 degrees. The smaller NGK CM-6 spark plug is very different from the Champion plugs. Unlike the others, this engines runs on a 4.8 battery pack (the voltage range is 4.8 volts to 6 volts). It may be possible to use a 6 volt battery, but I did not. It is a thumper with a nice low idle exhaust note that transitions to a smooth powerful purr. Starting was easy even on the first start of the day. I flipped it though a few times with the choke and then removed the choke and turned on the ignition, and it would start the first flip. One might err on the side of caution and use zip-ties to secure the module. You can haphazardly do this by feel, but the correct method is to use a torque gauge. I used PB Swiss?s Torque handle to make sure I got the exact torque on all six bolts. This is especially important since there is no center 10mm bolt to tighten.It was easy to start and required no carburetor adjustments for most of the break-in and through the prop testing. It is powerful, and I cannot wait to get it into a plane. It is well built and engineered, and with a third bearing, it is smooth at all RPMs. I found no problems that would keep me from using this engine. I wish they included the standoffs; that would provide some consistency.Product support from Cermark for my testing has been excellent; whatever I needed I was provided and they responded quickly to my needs with a phone call. I tried to get dimensions from a couple of these new on the market gasser sellers (I think the SPE) but never got a reply--forgot the distributor here in RCG. That made up my mind on a purchase.Plenty of 3D birds flying the 3mmVia a vintage ARF. Is that number a bit low. Great review BTW. You've got a neat setup.I did struggle with the tach as I was getting reflections outdoors off the props. I retook readings often, but finally settled here. The RPM range is to 7800.I did struggle with the tach as I was getting reflections outdoors off the props. The RPM range is to 7800. I tached the 22x10 at 5800RPM on the ground, which is not enough RPMs to get the thrust the Yak needed, and from reading other posts on the Internet was lower than others with the same engine. I switched out the prop for a Vess 23A which is a good match to other 50cc class engines. I also removed the spinner.The Yak would now hover but not really pull out of one. I switched to a Vess 22A, and the 3MM turned it at 6800RPM which is closer to where it should be. I have also read that Wildhare sells a Hop Up kit for these engines that is supposed to increase RPMs by a couple hundred, but I have not tried one. My Yak is a little over 18 pounds and its not enough power to pull out of a hover very well and thats with 6800 rpm on the 22A. Your RPM on the 22x10 is close to what I got with that same prop as well though.So the numbers can not be absolute. It was my method and those numbers might differ. Each and every method is going to differ.I noticed the difference when I had a deadstick and pancaked the gear, and yeah.The small muffler will choke up the engine a bit. If Ya'll want more power from that engine, give Tom (WH) a call and get the hop up kit- once you have it in your hands, it will become quite apparent why it makes more power.

I am sure that somebody will have some comments. Anything I would say would be seen as sales hype, so let the others comment. TFExcellent motor. No problems what so ever. Running Klotz at 50:1 ratio. Starts easily, transitions great, low idle, low vibration and pulls my plane out of a hover with authority with unlimited vertical.I like both for different purposes.I like the additional crank bearing over the DL and the actual Walbro carb over the factory carb the DL uses. Early runs of the DL had high needle blockage issues, that I believe have since been resolved. My 3MM has been mistaken for its brand-name counter part both in appearence as well as performance. It's got just about 2 gallons of 32:1 Pennzoil break-in through it, and I'll be switching over to 50:1 Bel-Ray MC-1 pretty soon. I am very pleased with torque throughout the throttle range, transition from low to high -even though it's still a little rich for break-in. I have mine in a 15.5 lb Extra 300 that rivals my bud's same plane powered by a DA 50 - definately gives a run for the money. I would advocate the engine, as well as buying it from Tom at Wild Hare for the service and guidance.No reason to run a 32:1 ratio for break in. After a couple heat cycles the ring should be seated. You dont have to run gallons and gallons of fuel thru two stroke gas motors to break them in. Fast idle for a half hour on the kart stand and then go race at 18,000 RPM at almost constant full throttle for up to 45 minutes straight. These guys that run 5 to 10 gallons of 32:1 on these motors don't know what they are doing.I am pretty careful in the first full throttle run up to be sure it's not too lean, after that I just fly it. After 1 tank at 32-1 I will use anything that's about. Ideally I would do 1 tank at 32 to 1, with the first minute or so on the ground to be sure it's not too lean. Fly out the rest of that tank and go to 50-1. I do not think synthetic oil is good for the first few tanks, I feel the rings seat better with mineral oil. Afetr that use what makes you feel good. TFMan this engine pulls like no other. Within 10 flips it's already starting. And I only have maybe 2 tanks through it. It flies like it's on rails for the speed record. I can understand where someone might think that this engine is too good to be true. It is worth every penny and more. I think the sellers are getting cheaped out. But hey I'm not complaining.Close to factory settings. And my fuel mixture is Lawnboy ashless at 40:1 I think.Seems to me like you may be comparing apples to light bulbs. Just visit the website for DA, 3W, BME, ZDZ, Fox, Zenoah, Brilleli, etc - the break-in durations are all a tad different (I'm betting due to differing ring hardness) but all begin with 32:1. Tom is surely diplomatic by offering to agree with you, Tim, but then describes the break-in to begin with 32:1. You can download the manual for 3MM if you Google it and it will suggest to begin with a natural 2 stroke oil at 32:1. Lawnboy is often advocated, but I find Pennzoil 2 stroke outdoor aircooled will leave less carbon - even though the first tank of Bel-Ray MC-1 at 50:1 will burn it all off. This is like hearing people say they don't understand why anyone would jump from a perfectly good airplane: Only those who never have will make the statement. Tim, I can tell by your assessment you've never enjoyed the pleasure of breaking in a 3W competition series twin. I'm on my fifth gallon of 32:1 and it still gets smoother and more powerful with each flight. I have known guys to start with 50:1 synthetic, and after five gtallons still have not bed the rings. A few tanks of 32:1 natural.I won't argue with you that I don't know how to properly develope an engine or its break-in process, but by God, I do know how to read the instructions and I'd bet anything that all those Porsche engineers who work for 3W know a little something.
