Good to hear please keep us updated. I should be ready to run the engine once I get it installed on the airplane. I will have some pictures to post tonight on my new throttle and choke arms from Kunkel. I am also going to be using a APS external fuel pump. I don't know if it is really needed but I already have it so why not. Steady .3 bar of pressure and with my tank location in the Yak should help out with the starts. More to follow. Take care.

Jason

What would be the best and safest way to attach cables for the throttle and choke. Is it advisable to use a servo for both or would there be a risk of the choke opening up when priming. Can you post some pics of your setup.

Sharman,

I am planning on running a choke servo (JR DS821) and a JR DS8231 on the throttle. I am using carbon push-rods and titanium rod ends from Central hobbies with 4-40 hiem joints, I have used this in the past and like using the carbon pushrods. I have not decided on the throttle and choke arms yet. I have a set from PSP MFG and a set from Kunkel. I like the Kunkel arms but the PSP arms fit better in this application so I will probable use them. The PSP arms are the tear dropped shaped ones that require you to drill and tap your own linkage holes. I am starting to work on the throttle and choke setup now and will post progress over on my FG thread. I will also post final pictures of the set-up here to help others who are not following the other thread. Here are the pictures of the different arm set-ups along with the fuel pump I am going to be using. Talk to you later.

Status: offline 		I got a nice surprise today! The exhaust ring showed up and it is beautiful. Great work Diego and crew! I also got the refund for the Software and USB cable just as Diego said he would do. Excellent!
Please check out the thread on FG "Hempel 170CC Yak 55m with SL150 Radial Assembly thread" for a updates as the airplane is built up. Not too much longer and I should start running it, just waiting on a Spark Switch from Powerbox for my ignition and fuel pump. I am planning on putting the smoke tap near the top of the exhaust ring to make sure the oil gets heated up. Talk to you guys later.

Status: offline 		I temp installed the ring and it fits great. A very small amount of prying with a small screwdriver to a couple of bolts holes to line up but not bad considering 21 total cap screws need to be in alignment. My biggest worry was stripping the aluminum threads in the head but I only had one screw that was a little difficult but with a little work to align it using that small screwdriver took care of it. My camera ran out of battery life so the only pictures I have at this time, is with the cowl on. This engine and exhaust ring fit great on this airplane, almost like the engine was made for it. Total weight of the engine, exhaust ring, and ignition is 13.55 pounds.


I took the ring back off so I can install the smoke tap. A question on location. I understand that the tap should be at the top of the ring to make sure the oil get heated up but is it better to mount it on the aft or forward portion of the ring or for that matter on the ID or OD? Sorry for the noob question but this is the first time I am running smoke and want to make sure that I get it right the first time. The ring is expensive and I don't want to screw it up. Take it easy.

Status: offline 		Will got the first couple of runs in on the motor and it is a good runner, super easy starter and good transition. A few issues to work out but nothing that we can't figure out. The max RPM we could get was about 4,800 then as we ran the motor, the RPM was dropping to max of 4,200 rpm, little concerned about the drop. I only made minor changes to the needles, max of a blade width from the factory and they stated that they were able to get 5,280 rpm. I have tried to duplicate the factory set-up. The only change is the weather, electric fuel pump, I am using 100LL AVGAS. Needle setting from the factory were high 1.75 and low 1.25. I will post more as I get it sorted out. First impression are very good and if this motor continues to be produced, I can recommend it once they get all the business items worked out. Great job on this engine! Link to the video.



Additionally, here is what the plugs looked like after the engine run. Temps during the engine run average 170-190 F on all cylinders with #5 being the hottest. Take care guys and sorry for the long delay in the first engine runs.

Status: offline 		Hello All. I am interested in possibly using this engine on a 1/3 scale Waco, but I have some questions. It sounds like the engine has oil inside the sump, rather than having a total loss lubrication system where the fuel mix is run through the crankcase like the Moki engines. Is this true? If so, why is it required to still mix oil with the fuel? Thanks in advance.

Charlie,

The oil was used for the front distribution gears instead of the grease that the Moki uses, to the best of my knowledge. You still need to mix oil and fuel. I hope this helps.

In respect to the engine, I do not know when it will ever be available. I can not recommend it to anybody right now. I sent my motor back to PRM Italy for repairs on January 26, 2011 and I still have not got it back. The cylinder heads leaked oil and fuel were they screwed onto the cylinders. Six months have passed with spotty communication and nothing in return. Then on July 11, 2011, I received this message from Diego.....

diego to me

show details Jul 11

Hi Jason,

I sold the design of engines, the buyer has all your names to continue to provide assistance.
I am out of my company 20 days a month, I can not continue to manage the engine department.
You will be contacted by the new owners. Perhaps they will keep the brand because it's all ready for marketing.


Diego Lazzarini

That was the last time I heard anything from Diego and PRM. Three E-mail have been sent out asking for contact information of these "new" owners, were my engine is or refund if not going to return my motor, and nothing from Diego or the company that bought the design. With all the mechanical issues the motor was having I asked for a refund numerous time and the answer I got was "go ask Luigi for the money since you paid him and I (Diego) never got the money from him(Luigi)" So as it stand right now I have been ripped off for approximately $3,250.00. I am not sure if I will ever get a working motor or the refund of any sort I am owed from either Diego, the new company, or Luigi. None of these guys want to stand up and do the right thing, so I will advise you guys to stay away. I have all the e-mail traffic if you guys would ever like to read it.

Please read my thread on F$%ing G%^nts (Hempel 170cc Yak 55m with SL 150 Radial engine) in the build thread sub-forums. My username there is Spookyeng. It spells out everything that happen.

My recommendation would be to buy the Moki and never look back. That is what I did for my Yak and I should have my new Moki 250 today.

Don't get me wrong though, the SL/PRM150 is a nice motor in theory and it did start every time, idled well, and ran fairly well factoring in the problems with the cylinder heads leaking. It still required tweaking before coming to market to work out all the bugs. I believed in the motor, Luigi and then Diego and was let down by all three with nothing to show for it except for frustration, lost time and money!!

I wish I had better news but these are the facts and who know the fate of the engine. I wish you guys all the best and if you guys ever want to talk about it off line, drop me a PM or give me a call. Take care.

Jason

Status: offline 		Thanks for the heads up, Jason. That stinks, it looked like a good engine. I was hoping to find something that didn't require mixed fuel and oil because I wanted the plane to smell scale running on 100LL rather than smelling like a chain saw. I originally was interested in the 3W 256 radial but that never materialized, either.

Charlie,

No problem. I do not want you guys to make the same mistake I did. It would be cool to have some sort of dry sump or wet sump gas radial. Take care and all the best.

I hope you have finally realized the truth and please tell everyone why they need not fear to have lost money. I'm waiting for the Italian judiciary to do its job but I will help you solve your problem with my. Do not disclose my news but communicates to others that I am always here and I follow everything from afar until I have my truth.

Now there are very intense investigation against this company that was hired to make the engines for the SL engines.

At this moment we are working to design engines for ULM radial 2500cc 110 Hp and models of aircraft 150cc 400cc Gas.

Put on line the new brand with the new site.

But this will take time.

No, I understand very well your English, but I answer this .... it is easy for you because you're just talking merchants. But if the DL were chudere feresti you what? you would have more engines sotituire and what would you do with clients who have problems?

I am a designer who designs and creates only prototypes and then relies on the companies that produce should be honest and just to me but not so.

I tried 2 times and 2 times I was screwed. People do anything for money.

I love modeling and I do most of this work for pure passion.

However, I will refund you money engine and my clients quendo me my economic conditions permit.

I think you're what you have pleasant voice in the matter since they do not know the details so we strongly ask you to refrain from commenting without knowing the details.

Jeson and I know well what we mean.

No offense you are a trader and a dealer, I am a producer and there is a big difference.

This is not to offend anyone let alone one of my colleagues. But I reiterate that it's easy to talk without knowing the facts well.

thanks

A greeting.
