I ordered my DL this evening for an Aero-Works Extra 260. I have a DA 50 and will be interested to see how they compare. I will post my experiences. Nex weekend after I get a few flights on it.

Is anybody using their motor mount or just stand offs?

I thought they provided some psycho angled aluminum thing for mounting.

That's a good price it seems.

looks like the new version based on the real standoff towers not the gutter mount
317 plus 27 or 36 shipping depends so not a huge savings let alone getting any parts support

Another alternative in the US that *does* provide parts, service, phone consultation, etc. is www.DLUSA.net in Irving, TX. Bob Kramer runs it, and is first class in taking care of customer needs.

Yes - newest version now has machined standoffs, very nice parts, great carb, and the Rc Excell v.2.0 ignition which is hard to beat.

DLUSA is proud to announce yet another improvement to the DL50 engine; the crank case mounting “ears” have been increased in size by roughly 160%. With the increase in size comes a similar increase in strength and resistance to damage.

Please keep in mind though, we still don't recommend crashing your airplane to test their new strength


Guess they fixed the weak rabbit ears too

The one nice thing is this engine doesn't need to go to a shop for a rebuild since there's no 3 piece crank to deal with it as easy to rebuild as a nitro motor
which is big plus on a engine with no warrenty except at the time of sale it will be free of defects I guess once you bought it it yours

I don't unsderstand the whole "why don't you read the 2600 post thread, the answer is in there" thing. If your gonna bother typing something then it might as well be helpful and productive, or at least funny. Many of us come here to save time, not spend 40 hours sifting through a thread to find something.

Still not too much about performance or longevity in the responses. Got 2 gallons through mine. Pulls about as strong as my DA, maybe a hair shy, but my DA is fully broken in. I was getting 7000 on a BME 22x8 second tank. Got a Zoar 23x8 on it now and pulls very strong. Compression is still very low. It really increased on the first 2-3 tanks but not much difference in compression since. It is easy to start but takes 4-5 more flips than my DA. I like it and so far is well worth the money.

I am not being negative, but I hear from guys that own both.... the comression is down.

How about "compression is DIFFERENT" ?
Particularly as that is a variable measurement, probably not done with a gauge under controlled repeatable conditions, hence, rendering only subjective opinions of the individual. That's not a "bad" thing, it just renders the information less useful to many.

I can tell by flipping the prop through any of my three DL's whether or not they have a "prime" in the cylinder, whether they are cold or hot, and, without looking, probably could tell which was the newer. Because they exhibit different compression "feel" because of all these conditions.

The compression of these seems to change quite a lot based on all these variables.

What I *like* the most, is that they are not "over-compressed", and thus don't detonate on reg. unleaded, and are a little more docile for the timing provided.

I should have put, that the compression is less than my 3 DA-50's and one of my friend who has my gauge and checked all of them. I am not saying it is better or worse. Just fact. More compression does not mean more power.

Not doubting it at all; no beef. Just wanted to mention my thoughts on the issue.
I wish I had a DA so I could compare the two in my own shop....

I am a pro DA guy, but I will say I am eager to try their 100 when it comes out. They should be out by summer? Some of you know more than I. I honestly hear only good things about this DL. Many people claim it stronger than their DA....

I own 3 DL 50's and 1 DA 50. I am running two on the original mounts and one on stand offs (DL). I have 30 gallons on one engine with original mount and zero problems. Only a couple gallons thru the others. I switched to my DA 50 on the 30 gallon plane and flew for 5 gallons then switched back to my DL and am much happier with the DL performance. Back downs are more controlable and the DL doesn't burble in the mid-range like the DA and doesn't lean out when inverted like the DA. This engine is the best running, lowest cost, easiest to to use, 50cc on the market. I will be selling the DA and ordering another DL. I will say the DA muffler is more substantial and a bit quieter. By the way I am a big DA fan and have DA100 and DA150. Flawless engines. I just think the 50 could be better like the DL.

Wow, that's a LOT of run time. A DA 100 burns 2.5 oz a minute at wide open throttle. That would mean that at a DA 100 burn rate, you put 25.6 hours at wide open throttle. IN other words, the amount of fuel you burned (30 gallons) would run a DA 100 at 25.6 hours... That's a lot of hours. Did you have it in the same plane for that many hours? I would have to guess that it gets near twice the mpg that the 100 gets.... thats 50 hours roughly..... Sure you put 30 through it? I keep a very anal log book on all of my planes and motors and to put 20 hours on a plane takes a lot of flying!

Well some of us do fly a lot. Most at our field come out for an hour or two and get in three to six flights but when I go to the field I don't sit around and talk. I go to the field and get at least four flights an hour and fly for min. four hours at least four days a week and more (7 days, 8hours) if I can find the time. I bought my DL from peak when they first came out. I have crashed the plane and rebuilt/replaced three full airframes. Not every body can fly that much or fly that long but that doesn't mean it is not possible. I have only been flying for three years but can back down and tailtouch repeatedly because I fly a lot. We have pilots at our field five days a week or better so there is always someone to fly with. I don't drink, and go to bed early to be well rested so that I can have the attention span required to fly for long intervals. I mix my gas five gallons at a time and use electric fuel pumps so my pit time is low. I fly in the wind when all other pilots can't or won't. I buy props in bulk and keep plenty of spare parts on hand. I bring adhesives to the field and will do onsite repairs if necessary. I also always have a plane in stock waiting for the next mishap so that I can repair or replace overnight. Being self-employed makes all this possible. Bet more pilots on RCU wish they had that kind of time and dedication of financial resources. I know I am thankful for the ability to be able to do this but I also prioritize and work odd hours in a high risk, high pay occupation. And if I did not have a great Wife it probably would not work out.[:@]

That's me... when I go to my field.... I go to fly. I mean I am social and all, but I fly a lot when I am there. It gives the old timers something to watch, after all, thats 50% why they are there anyway. Now that I moved to my new place, I have my own full scale grass field... so this summer, no excuses! I have a brand new inertia dyno that I built and I am eager to start dynoing these motors and testing pipes, cans, etc.

I have been trying to run this particular motor to pieces but it just keep on running. I do fly my 40% and 35% often but these 50cc have been my mainstay. They fit in the truck next to the big ones nicely. With the cost of these DL 50's i can have three planes out fitted for the cost of one composite 35%'er. Maybe I should sell the 3.3m Yak, 2.5m Edge 540, 3.1m Extra and take the money and build a bunch of 50cc planes.

Have all of the old style motors with the thin mount ears been sold and out of inventory?

Default RE: DL-50 gas engine

Probably, or maybe you can ask for the old version and get for $370. My high timer has the thin ears and 1st version mount but no probs if you don't crash it into the runway. Did this already ( 1st flight, radio module on transmitter went out ) Bob at DLUSA.NET provided parts (Cylinder, backplate, gaskets,and mounts) at what I thought was a reasonable price. It took about 30 minutes to strip and reasemble engine and it is my high timer now. My #2 has the thin ears and the second version mount and no probs at all. Probably 3 gallons on that one. #3 has the thick ears and stand offs. Very nice. 2 gallons on that one. It is nice to see that the manufacturer is listening to the customer and distributors and making changes to an already great design.
