nmking09 -> Let's try again DL-50 (3/9/2007 3:01:08 AM)

I wanted to re-start the recently blocked DL-50 thread. Please, can we keep this on track and stick to the topic of the engine, its quality, and performance.



PlaneKrazee -> RE: Let's try again DL-50 (3/9/2007 3:06:42 AM)

Is this engine still offered on Ebay? Or is asking where to purchase it off topic?[;)]



nmking09 -> RE: Let's try again DL-50 (3/9/2007 3:15:42 AM)

I killed my zenoah yesterday, so I have been searching e-bay and haven't found one in a while. Peak says it'll be 10days. Just keep your eyes pealed.

Note to self: engines don't run well on carb screws, no matter how good they are, and even if you start them on gasoline. Also, in the piston vs. carb screw battle, the piston ALWAYS looses!!!

No it's not.

Off topic in this case is more towards the political, economic and otherwise member flaming and bashing that went on in the other thread.. It's not uncommon for thread to wander now and then but as long as it remains RC related and everyone remains calm cool and collected, the mods will stay out if it and most likely the thread strart will end up with a great thread.

There is a long running thread in the 3D forum on the GP Ultimate. it has strayed came back strayed again and came back and not one time have I ever had to ask anyone to settle down. The very large EF Yak thread was the same way. I think that thread became the largest one ever on RCU but I can remember only one time having to clean it up as again everyone basically kept to the subject and were very nice to each other



fay -> RE: Let's try again DL-50 (3/9/2007 3:37:11 AM)

wow.. so many unrelated post on prev thread. In one day I can see few pages but yet not the full review.

does anyone still on the engine and please let us know what the result and as now we still don't know how the longlivity.

About the last thread I saw blood.. and I can guest the mounting was broken.. does it's hurting someone?



nmking09 -> RE: Let's try again DL-50 (3/9/2007 3:41:56 AM)

Bad mounting job, these are not toys. It really looked like a harmonic oscillation break, induced by an extremely rigid mount. It has convinced me to purchase some stand offs instead of using the supplied mounts.

Xoar 22x8, lawn boy oil 32:1, 40deg F, 300ft ASL, and 7200 rpm.



PlaneKrazee -> RE: Let's try again DL-50 (3/9/2007 3:53:02 AM)

Bubba,

I was only kidding.

I could not find a listing for the DL on ebay or Peak. If you click on the 10 day thing it says item not found. I hope I get the one I ordered last week.



bubbagates -> RE: Let's try again DL-50 (3/9/2007 3:59:36 AM)

Sorry, I thought you were serious. I'm still a little punchy I guess

Anyway, I seem to remember a few posts in the other thread saying that the ebay sale threads were gone and peak had removed them but 2 days ago peak was 10 days away from getting more

RCIGN1 says he is getting one and I am waiting on his and Boss's results before I decide. Boss did post the pics of the damged one in the locked thread, you can still view them, you just can't add a new post in there

Never solid mount any engine to a bench! That was crazy.

PlaneKrazee -> RE: Let's try again DL-50 (3/9/2007 5:27:49 AM)

How are you supposed to mount it?



nmking09 -> RE: Let's try again DL-50 (3/9/2007 2:57:30 PM)

I used wood or something that isn't as rigid as 0.5 inch steel.



Cryhavoc -> RE: Let's try again DL-50 (3/9/2007 4:22:51 PM)

I just did a search under Toys and Hobbies in e-bay and found 2 people that had sold the DL50 and only one that was doing it as a business, (sylvian1975). They were out of Hong Kong and also selling combo's of the EXTRA 330L ( CMP ) with the DL50 for $640.00 + $150.00 shipping. The plane looks just like the one offered by Nitro Planes. It appears also that he sold 5 of them (for $329.99 + $35.00 shipping) on March 3rd. He also hasn't any feedback, (their total was only 76 - all positive) for any of these purchases probably due to the fact that none of them have had time to arrive as of yet to be tested. What I find more curious is that he isn't offering them for sale at this time.

I'll watch his account for feedback from the people who purchased these engines and I'll contact them directly to get their opinions.

That's about all I could dig up. No reports regarding hands on running of this engine from anyone yet?

UPDATE: I missed another individual, (red_noir) that tried to sell 2 of these from Canada. Neither sold and he has only 11 feedbacks, all positive.



PlaneKrazee -> RE: Let's try again DL-50 (3/9/2007 5:07:20 PM)

Cryhavoc,

There is a report above in this thread and several in the closed thread.

I emailed Steve last night, the guy from ebay and he said he will have more stock in ten days. I also have asked about spare parts this morning but probably won't get an answer until evening do to the time difference.

It is better to wait and sell a properly manufactured engine rather then sell a crappy engine, have customers beotch about it and get a bad name. It could be they are making sure the new production run meets the required quality and specs. The run coming out now is following the Chinese new year. I guess the whole country takes a vacation, Kind of like Christmas vacation here.

My engine is from the other batch and should arrive sometime next week.



PlaneKrazee -> RE: Let's try again DL-50 (3/9/2007 5:08:38 PM)

It appears demand is outstripping supply.



nmking09 -> RE: Let's try again DL-50 (3/9/2007 5:32:44 PM)

I left positive feed back with Steven (sylvian1975) on my DL purchase, and I have conversed with him sence then. He is a very reliable and trust worthy person. Don't hesitate to deal with him!!!

SkyPilot, before I bought mine I asked him the same question and he said that he could get any replacement parts I needed.



frieshoo -> RE: Let's try again DL-50 (3/9/2007 6:38:33 PM)

I can't believe someone used the mounts. DL is making a big mistake including them with the engine. I used my DA standoffs.

I have over gallon thru the DL50. It is a little rough at idle. I still think I have an air leak, because I removed the carb, and flipped it 180degrees.... I could have under tighten, or over tighten the carb/intake manifold.

I'm still getting 7000 rpms on a NX 22x8. It's pulling like a mule.



hamman -> RE: Let's try again DL-50 (3/9/2007 7:31:26 PM)

I think Ralph has the best idea using flat aluminum then mounting stand offs to that, much like my plan I mentioned in the other thread of using square tubing. The DA type mounts are far better then the extrusions but the problem is that there is too much leverage with the long standoffs and in the event of a crash they will break off the cast tabs on the engine. That guy made a big mistake not to have wood in between the mounts and the stand, also did you notice that he had only 2 bolts in the prop? You have to wonder if the mounting bolts were tight although it appears that the bolts in the broken pieces are tight. I have run about 3 quarts of gas through mine on the stand and 3 flights on my extrusion mounts but they are being replaced soon. Hamman



frieshoo -> RE: Let's try again DL-50 (3/9/2007 7:44:38 PM)

Hamman,

Good point about the 'leverage' on the standoffs during a crash. If, and when I crash (and I will crash at some point) [8|].... I hope my screws pull through the firewall... LOL!!!! I don't think the mounts ears will take much leverage before they break....

One thing about the accident Boss is reporting.... We don't know several things about the setup... Was the prop balanced? Was the engine properly tuned... etc... I feel bad for the guy that got injuried. I have had 3 trips to the ER, and every time it was my fault entirely. Over 100 stitches over a 3 year period...



Herby 1 -> RE: Let's try again DL-50 (3/9/2007 7:59:34 PM)

2 bolts through the prop on the test stand is no problem, I run 3W 150s on my test stand with 2 bolts through the prop..The bolt are metric grade 12.9, same as US grade 8...Gotta be TIGHT...They don't break from being in tension, they shear if loose....That's why I like a single 3/8 grade bolt in the middle, no shear, will not break from tension..If it gets loose the prop just spins but won't come off....[:D]



Bosshossv8 -> RE: Let's try again DL-50 (3/9/2007 8:15:23 PM)

I do not know all the parameters of the accident. Ecxept that the motor vibration got very bad and it flipped up when the mount was breaking.

They said the motor ran OK, their mistake was the hard mointing....I bet if you used that mount on a plane, and watched it closely...it would be alright...for a while. Any incorrect bolt angle or loose bolt and it would accelerate the failure time. JMHO.

I will use standoffs on mine this weekend. With a balanced prop.

It has been suggested to me that the phots are fake and a setup...accusations from a few people I have a lot of respect for and are friends with.

They are not fake. Two people noticed the different floors in the motor and blood photos...yes ,the bloody photo was taken in a different place...as were others that are not posted.

The motor runs fine, the mounting method and the mount are the problem. No one I know is trying to disseminate false tripe about the motor. I asked If I could post the pictures from the parties involved, to give everyone a heads up.....I am glad they gave me permission, because if I didn't , and someone got hurt, I would feel like dirt.

Now..................................

Next thing on the list ......mouning this to a plane and running it. I am on it........

ANd if this thread gets shut down, it is because someone called names.......save that for the playground boys.............I am interested in one thing....a cheap motor that can be disrespected with impunity.

I am using a DA-50r muffler instead of the DL...why??? Larger diameter output pipe. Iwill ry both....but, I bet the DA's larger diameter will give a better RPM reading after break-in.



frieshoo -> RE: Let's try again DL-50 (3/9/2007 8:21:44 PM)

The stock DL muffler is very loud. I might get a DA pitts muffler, if the engine keeps running well.



Bosshossv8 -> RE: Let's try again DL-50 (3/9/2007 8:23:56 PM)

is it loude rthan the DA?? I cant see how...it has a smaller pipe.



frieshoo -> RE: Let's try again DL-50 (3/9/2007 8:36:40 PM)

I've never used a side dump muffler on my DA's, but It's definitly louder than the DA wrap around pitts.



PlaneKrazee -> RE: Let's try again DL-50 (3/9/2007 8:38:31 PM)

nmking09,

When I asked about parts I wasn't clear and said he'd be getting engines. I replied again and was much more specific. Waiting on his answer. Below is the corrospondence so far.

Are you going to be getting any more DL50 engines and if so when?

Regards,

Brian


Hi Brian , I will have 10pcs coming and be relist on next week , now just waiting for MFG confirm delivery schedule with me . please take notices my offer . regards Steven


Very good,

What about spare parts and their prices?

Oh, Do you know if they will be making different stand-offs? I heard the Extrusions could break and or have broken.

Regards,

Brian


Hello , the price should be same as before . I sold many this item but didn't heard the stand-offs have problem from buyer . may be I can ask the MFG will they making different stand-offs , thank you for your info and suggestion. regards Steven
Steven,

I am asking about spare part prices and availability. Spare piston, piston ring, cylinder, crankshaft, gaskets, etc. Do you have spare parts, and how much do they cost?

On a website called RCU they show what happened when a mount broke. This is the website that let us in the USA all know about the engine,

Regards,

Brian


My only question is if I need a ring, (maybe Frank Bowman if I send the cylinder), Piston, cylinder, crank, rear case, etc. will there be someone in the US that has or will have parts parts?

I doubt anyone is supporting these engines, not at least until a U.S. distrubutor picks them up as a line of product, then watch the price raise. And this IS all about the price.....isn't it?

I think we are getitng what we paid for.....and nothing more. There are motor companies that provide the support, with appropriate increases in price.

Buy two....one for spare. I wonder if anyone is going Compete in IMAC with one of these?.......I would use a motor with domestic overnite support if I was in it for the points standings,,,,not something that parts had to gotten from overseas.

----------------------------------------------------------------

waiting for 30 min epoxy to set up on a thrott servo mount.....[&:]

This will be flown in an 87" Yak-54 at about 16lbs 9oz. An old KMP/Ebay Yak.

First prop will be my trusty breakin prop...a Mezjlik 22 x8.
