RE: DL-50 engine
My DL-50 spins a JXF 22X8 at 7650rpm. And it runs perfect all day. Buy a DL-50.:D:D:D:D

RE: DL-50 engine
All these people and nothing to say?;)

RE: DL-50 engine
Paul, are you serious with the 7650 on a 22x8? Mine turned "only" 7200 withthe same prop. And with a 22x10 it dropped to 6700. Now those numbers where measured from aTBM wooden prop.
|
RE: DL-50 engine
7900 on a Vess 22A and MTW RE2 for break-in, currently 7200 Vess 23B...
|
RE: DL-50 engine
My motor has about 5 gallons threw it and you will get those numbers on a JXF, MENZ our ZOAR. That TBM prop you have is a very high load prop.

RE: DL-50 engine
I'm one that typically goes for the higher dollar engines simply because they will last near forever if taken care of. That makes them less expensive in the long run because I only have to buy it once. Power and reliability is waay up top with the "name" 50cc engines, especially with the BE 58. I don't use rpm numbers with any engine because I've had too many propellers turning a lot lower rpm outperform the high rpm spinning props by substantial margins. How an engine and prop performs in actual flight conditions means more to me than rpm or thrust counts.
The most consistent reports coming from the budget engines of late seems to be the DL 50. DL also has the longest history of all the new engines at the moment. Somewhere around 2 years now I believe. RCGF is getting up there in both peformance and quality. The XYZ 50 is doing well but it was never alledged to be the most powerful of the lot. There seem to be balance and case issues here and there with the MT 57 but the 50 is doing well. The Area 51 is doing very well. TMM (previously 3mm) has a very reliable engine with their 52. Parts and service availability is an important factor with any of them. I have DL and RCGF engines and like them. I tested two original 3mm 52's and thought it was a good engine that would last a very long time. So you have a few choices but I won't suggest one over another. Some might say I'm an elitist but I believe that if you can't afford to by the best in this hobby you should hold back from that part until you can. It's cheaper in the long run. There's no hurry to move to the next level. It's a hobby not a career. |
RE: DL-50 engine
I started out at 6900rpm on the same prop. And after break in 7650rpm is what I ended up with. RPMs is a good measure of power. That's how we compare on this and other forums. I have a DA-100 and love it. But I got it in a trade. If I had to buy a 100 it would be a DL-100. The DL is a "budget" motor but it is one heck of a good one.

RE: DL-50 engine
Paul,
Would you please keep that darn MN weather to yourselves. Here in Florida they are covering up plants and turning off fountain pumps because it's heading to the low 30's. Been too windy to fly, might be able to get out tomorrow. A friend from Stacy was here for two weeks and went back Tuesday to your lovely weather. He's still crying. Don't ask me if I miss MN in the winter, you know the answer. Any, back to DL50's. I had a problem with dirt in the carb causing a dead stick last week. Had to clean the carb twice to get it to run right, dirt in on the high speed needle side. While in the process of fine tuning the engine by flight performance, the engine died again. Two flips on the ground and it was running again. I think the low end was a little rich because it died after running a little while at idle (while in the air). I did lean it a little afterwards and didn't have any problem after that, but only got in one more flight. Is it possible for the engine to die in the air as I described? I runs like a champ as it did before the carb problem. BTW, I've got some filters coming for the line between the carb and fuel tank, as well as for the vent line. Chuck |
RE: DL-50 engine
ORIGINAL: Tired Old Man In all the DL 50's out there that's the first time someone has said his DA had twice the power.... Good to see they have one like that. That means my Taurus must have at least 2.5 times the power;) Yea, I know, but I didn't start it....I promise to sit back and watch the fur fly with no additional input from me:) I guess it's time for someone to break out the ruler. <G> Ed Cregger |

There's no hurry to move to the next level. It's a hobby not a career. You are entitled to your opinion, T.O.M., and it sounds very reasonable and well thought out. My way of looking at it works for me. If my less expensive engine only lasts half as long, but only costs half as much, then I'm happy. Why? Because every once in a while I dumb thumb a model into the ground. Yes, that is happening more and more the older I get. It's not so bad that everyone runs for their cars when I throttle up to takeoff, at least not yet, but this old dog does make a bad decision once in a great while. I'm not willing to bust up $700 worth of engine when I can get a perfectly good running engine that will do the same job for $360 (what my DL-50 was when I bought it). Ed Cregger |
RE: DL-50 engine
The other thing that I always differ with T.O.M. on (and nothing personal of course Pat) is that my DA-50 never ran to my satisfaction, the dreaded inverted dead sticks no matter what I did to try and fix it. So it's a moot point. If it won't even run right how can it last longer? So for me that wasn't even in the equation when I bought the DL, not price either. I wanted a DA-50 that ran to my satisfaction. It's called a DL-50. Same weight, same power if not more. Heck if it only lasts two seasons it will have done better than my DA-50.
So the DA and even ZDZ doesn't last longer for me. I just didn't like the way they ran. The DL is awesome. And to give it away at $370 shipped, how did I get so lucky? |
RE: DL-50 engine
Stop using phrases like "giving it away at $370 shipped". They might see that and raise the prices before I buy mine for my ME109. Then I'll have to drive to your house and take yours, and I hate road trips.
|
RE: DL-50 engine
Joe,
You know I've never been in agreement with those that thought the DA 50 was the end all and be all of 50cc engines. Always on the other side of that fence for that matter. They were the best advertised though....There were, and still are, better 50's. The DL is one of them when it comes to tuning ability, and the power is very good. Now all we need to know is how long it will last and so far it's not doing bad. Ed, I understand, I really understand. I'm not getting any younger either and I find a little more altitude today than I used yesterday is my friend;) |
RE: DL-50 engine
you guy's are funny I like listening or should I say reading all the fun so to speak you guys have answered a lot of my questions but there is still one I think that has not been anwsered yet what kind of oil to run in the DL-50 i'm sure you guys are not just grabbing the first thing you see off the shelf I mean what brand is a good one in your guys eyes and why ????
Jim |
RE: DL-50 engine
Most people use Lawnboy at 32:1 for break in, then a good quality 2 cycle engine oil like Bel-Ray or similar usually available from your local motorcycle dealer. Always follow the ratio recommended by your engine manufacturer. Also keep in mind that you can run them at a thinner ratio for a little more performance with possible shorter engine life as a result.
|
RE: DL-50 engine
Do not use Lawnboy for the break in. Most people do not use it. Generally those that buy DA use it because that's what DA suggests. The stuff loads an engine and muffler up with crud faster than a landslide fills a swimming pool. Yes, it seats rings quickly but why do you ever want to initiate a fast wear pattern in metals? You can never go back and replace what you previously removed.
You want to thermal cycle the engine for a period of hours during the break in. Never cold, never hot, but temperature cycles that take the engine through reasonably normal operating temps without tagging the upper end of the temperature range. That means no long verticals or hovering during the first gallon or two. No rich running at idle or low rpm for long periods either. That does not do anything for the engine. It's not just about seating the ring and burnishing the piston skirt. The best engines I see are those that have piston skirts that are almost without wear and they happen with a gradual break in with excellent lubrication. Better to use a good mineral oil, or even a good synthetic for the first 3 to 5 hours at 32-1. There's really no reason to change ratios later but if you do hold the mineral oils to ratios no leaner than 40-1 and the synthetics no leaner than 50-1. Engines run cooler and cleaner that way. Last longer too. More oil typically equates with more performance, not the other way around. This has been proven far to many times for further debate. |
RE: DL-50 engine
You want a good bit of reading on what oil to run? I broke in on lawnboy ashless 32to1 and it is icky black stuff but it worked, and now I run Bell-Ray MC-1 50to1.

RE: DL-50 engine
Oh!! Chuck nobody likes a quitter. I was in Stacy 2 weeks a go drinking with a buddy. -10 when I left to come home. It does suck the big one. But I've got a little bit of happiness on the way. I ordered a 100cc aeroworks extra 300 on Monday.:D:D:D:D YIPPEEEEE!!! I CAN'T WAIT!!!:):):):)

RE: DL-50 engine
Paul,
Congratulations on the new plane. There are a lot of the big ones here at our field. I love to watch them, and would be tempted to jump into one, but two things stand in the way, actually just one -money. Besides the step increase in cost of the large size, they won't fit in our SUV. The car is maxed out with a WH 50cc Sukhoi. We will be due for a new SUV in two years, so maybe then I can move up to the 100cc size. 34 degrees at 7:30am Chuck |
RE: DL-50 engine
It's Trailer Time,
|
RE: DL-50 engine
The ability to transport has always been the limiting factor with plane sizes. You might be able to handle the cost of the plane but buying a new vehicle to carry it doesn't make a lot of sense unless you were already in the market for a larger vehicle.
