Karol...read post #639 on page 26. It was very touchy, but after at least 70-75 Heat cycles and some fine tunning, its good to go! It has very good compression and has a good bouncy feel now also. Capt,n P.S. Some full throttle short blasts are good too after warm-up.

My DL30 also has same tilt sindrome reported here.
at 2200 rpm hold ok in vertical, gentle tilt to horizontal the rpm will drop until engine quit.
boughted on e-shop in China, I have 2L ground break in on it and was very happy with it.

normaly i fly the engine at this stage, I may do that with this keeping the idle high.
look to me it is a carb problem, my DL50 don't do this!

I am looking to buy a dle 30. Is this a problem from a supplier with a certain batch or all the engines in general?

Doh!

So should I be worried? Does this mean break it in on the ground with a few gallons or is it ok to fly? I want a reliable engine. I had a RCGF 26cc in my extra, but it didn't have enough power and now I'm looking at the DLE 30.

I Can guarentee my problem was not the carb, I tryed 2 different carbs with no help. The problem is within the engine.

Craig,

Maybe you should buy a Syssa 180!

They are said to idle great.

I looked at them when i was at Joe Nall flying this year, but I've had such good service from my DL 50 that I wanted to give them a try. After all the reports here and elsewhere i decided to go with the Dl 30 and it fits my application better. I cannot use the syssa in my large profile because of the top center standoff. I think Ralph is getting close to figuring out what is going on.

You may be right, only time will tell. I should have worked on getting my DLE30 installed on my airplane. Instead I went to a swap meet and some items sold, but not too many. Lots of RC items of all kinds...just did not sell much. Looks like a lot of folks are stuck with a wealth of RC goodies! Capt,n[X(]

On another forum Ralph says he has it figured out, but is being pretty secretive about it. Typical Ralph, but if anyone could get it figured out it would be him.

The fix is in fine tuning, and try to prevent pooling...making it too easy to flood out on Idle speed. I got mine running good just by fine tunning. Capt,n Edit..UPDATE mounting the engine on a slight ange really did wonders for my engine. Capt,n

Some of us are having issues that tuning cannot fix. I hope your engine gives you good service from here on out, but the fix from what i understand is not pop off or tuning, I checked and adjusted both. Have you mounted and flown the plane that its mounted on yet? Or is it still on the test stand?

I will be recieving my engine back from Ralph soon and will report back when it gets mounted.

The engine is off the stand and I am in the process of installing it on my airplane. I did while on test stand, change the fuel line to a meium size neopreme Hays fuel line. Wish me a good flight, but I plan to fly fast and greese it in on landing. No fancy stuff on maiden flight! Capt,n

Looks like I'll be sending my engine back to Ralph C. as well. I tweaked on this engine to many times to know that it's not a tunning issue.

If you guys find out let me know. I am on my 4th gallon and it still quits so I don't think more fuel is the answer. I have tried lean, normal, and rich using a tach with no luck. I'm not a gas engine expert like some on the board, but it should not be that hard to tune an engine. I also tapped the float diaphragm which helped airborne. It has lots of power on the top end. It's the idle and quitting that's the issue. I'm going to try mine again this week and if it's still acting up I will get with Jody as I bought mine from Valleyview with my plane. It may just be an issue to a few engines that are defective. I don't think it's a design issue because we would of heard more complaints about it by now.

I am thinking that most of people are dealing with the issue and just not complaining about it. I could have flown the plane and just used a very high idle when flying and then brought the idle down on approach, but I should not have to do that and that is why I sent mine in.

qspilotcmh, what is the serial # on your DLE30 ?
Thanks

When I get a chance I am going to remove carb & reed box and look what the inside casting looks like. Good to find out this stuff. I cannot & will not send it back to where I got my Dle30 in Arizona. I was totaly banned from that site where I placed a lot of photos & data trying to help out. Life goes on...I had to solve and fix engines and worked on hundreds of them in my life! Capt,n

Craig,

you could be right. I did not notice it until I tried to get the idle low enough to land around 1809-1900. My SU26 had light wing loading so you have to get the idle back to land.

Cat power,

John,

anything you find out be helpful. I hope yours run well in the plane. It sounds like yours is running well.

That's funny...You HAD the first DL I sent out until you balked about the price and it was intercepted and got back...And then you misrpresented the circumstances on here...You're on your own, you'll probably find the fix..good luck...

Antique (RCIGN) for you the only thing that stands between you being a very good engine man and being a super person that people could admire you is yourself. I can see better now in realilizing the way you replied about Scott Brillie and his engines & Bob and a few others on RCU. I will not argue with you. But you know & a few others know I told you not to sell your DLE30 engines for such a low price that you first quoated. By the way..I had to pay the shipping to another guy who you sent my engine too. Hey I am not going say anything more...just turn my cheek. Tell you wife I wish her to get better....she is more important than any engine. Capt,n

craigteffe, I too have tried everything I could come up with including days that turned into weeks, of searching the internet for the fix. The issue is not any better, and now after damaging my plane 2 times from dead sticks, I am just wandering if all the money and time I have put into what seems to be a KNOWN defect in this engine was worth it????

There is reports all over the net of buyers who have bought these engines have the same running problem and no one has the fix yet.

Forgive me for seeming upset but after having bought a dle-30 that was JUNK when I took it out of the box, buying the parts and paying for them out of my own pocket, rebuilding the engine myself, then spending weeks pouring over supposed to be fixes and NONE of them even coming close to taking care of the problem, I have lost any faith I had for these little motors and the people who make them.

The sad part is, it looks like the buyers and users of these engines are being used as test dummies. ( with the buyer getting burned ). After 30 years of working on gas engines I can not believe that the people who make these engines did not know there was a problem. How many planes will be damaged, and how much money will the rc buyer loose before there is a recall or the manufacturer of the engine is forced to do a recall ????????

Antique, RCIGN, Ralph,

If you know whats wrong with the engines you sold why not share the information?

I was going to take the reed block out and look around in there. Capt,n EDIT....UPDATE... I mounted the engine on my Giles 202 on about a 20 degree angle...now no engine quiting...I even tried to make it quit...she just kept on Purring. Capt,n

Since there are so many problems with this engine, what is another choice for a reliable gas engine to power a 12lb plane if not the dle 30? Also some sellers are talking about the second generation of dle 30 now in stock. Are the problems solved or not with this batch?
