Caught between 2 engines here for my CMP Katana 140 S.
Looking at the DLE 30cc and the DLA 32 CC. Anyone had any experience with either of these engines. Are they a reliable, decent engine? Thank you for your input.

There is no doubt about the good reliability of the DLE-30

Ok what is the difference, which is stronger, better longer lasting? cat or milled.

The last thing I want to do is spend 300 on one of these and hover and have the bearings spin and cease up on me or lose the cylinder. and ultimately my airplane.

Virginia Model Builders pretty much sums it up.

The current DLE 30 is a well proven product, the current DLA 32 is also proving itself.
The DLE is most likely supported by more repair agencies than the DLA.

As for Cast vs CNC Crankcases?

MVVS, 3W, ZDZ, Zenoah - Cast Crankcases and winners of many many high level competitions. All are engines of choice for many top level fliers in many categories.
DA, Mintor, BME - CNC Crankcases and winners of many high level competitions. Also engines of choice for many top level fliers in many categories.


I purposely left out any Chinese engines when I mentioned the crankcases as ther is another category amongst those - Cast then polished or plated to look like they have been CNC'd.

I thought DLA and DLE were Chinese engines?
Are parts for these very hard to get meaning shipping wise. I am mechanically inclined but if I lose a bearing or crank, how hard and long does it take to get parts like this. Basically are they readily available and does it take 6 months to get the parts?

DLE parts are easy to get

I can't believe this kind of discussion is still taking place. Admit it's all about paying the cheapest price and make the call.

Most of the Chinese engines with a so called CNC machined crankcase have a cast crankcase that has been CNC machined on the exterior to appear that they are CNC machined from a billet.

The Aluminum-Zinc die castings are not nearly as strong as the aluminum billet stock that are 6061 T6 or 2024 etc.

I take I have heard of people talking about Ignition interference with 2.4 ghz on the electronic ignitions. has anyone had any problems with that regarding these engines?

I want to be able to perform flat spins, harriers, hovers with this plane and it can be done. but I want a decent engine to do it with. and one that has the power to do it.

DLE 30 has the power but the dla 32has a hair more. If the dla 32 is just as reliable, than ill go with the dla 32 for the little more power it has. if its not as reliable and parts take forver to get(in case of failure or crash), than im going with dle 30.

that why I appreciate your opinions.

What kind of material are these dle and dla engines made of?

How do you know it has more power, beware of any manufacturers HP claims.

They are all made of aluminum with cast rings on a chrome plated bore.

I wonder where people get some of their information regarding engine performance. Hopefully they aren't thinking that because an engine has 2 more cc's it has more power, might be more reliable, or have greater longevity. Some of us can provide a number of engines with a lower cc count that provide more power than larger engines in the class.

As for doing aerobatics, I think there's been more than enough historical evidence to prove that gas engines of any size can do everything that a slimer can, and do it longer using less fuel. As for ignition interference with 2.4. If a person fails to follow directions or shortcut an installation they can expect to have ignition interference with any frequency type. I've never been "blessed" with having that problem with 72 in any flavor or 2.4 but me, and many others like me, take the time and expend the effort to do things right the first time.

Scotty, you are nowhere the first to fly a gas engine. Many thousands have gone before you. The smart ones go with engines that have an established preformance history that also have a solid support structure. If you are scared of doing something different you should not be doing it. However, if you take the time to read instruction manuals and follow directions, flying gas is really no different from flying glow. The propeller goes round and round until it runs out of gas.

Scott if you are just looking for someone to tell which engine to get then get the DLE 30. Tower Hobby sells them if that tells you anything.

I want the dle 30 to start with anyways but I happened to step on one of these DLA 32's and I got interested and wanted opinions. I will take the advice and stay with DLE 30

This is my first gasser, and thats why I am asking so many questions.

To Tired old man. I am not afraid per say, im just confused with everything there is out there and hearing this is reliable and that is reliable, i just dont want to put something in there thats going to fry and screw up my plane. I agree with the doing right the first time. I am thankful for all your inputs and opinions.

To everyone, thank you so much for your help. Im going to stick with DLE 30.

I believe you are making the right choice with the DLE. A lot of time, effort, and expense has gone into making this brand one of the bset, if not the best, performing and more reliable engines coming from Chinese manufacturers.

I needed a new 30cc size engine. I considered the DLA 32, but in the end, I went with the DLE 30, precisely for the reasons these other gentlemen have stated.

The new DLA Engines, manufactured after ~June 2013, are CNCed from 7075 Billet Stock Aluminum to a precision of plus or minus 0.01 mm (`0.0004"). The prior billet material was 6061. The 7075 material allows for precise locational positioning of the German "FAG" bearings, thus less vibration. I believe this is the same material and bearings used in Desert Aircraft (C) engines. Our experience with DLA is excellent for both power and reliability and service. There were about ten significant design, material and manufacturing upgrades made in the June 2013 time frame. The DLA engines come with a three (3) year limited warranty and parts are stocked by the USA Distributor: Golden Skies R/C Aircraft, Inc. http://www.goldenskiesrc.com

REF: Aluminum alloy 7075 is an aluminum alloy with zinc as the primary alloying element. It is strong, with a strength comparable most steels, and has good fatigue strength and acceptable machining. Its relatively high cost limits its use to applications where cheaper alloys are not suitable such as 6061 alloy.

The 7075 alloy is often used in transport applications, including marine, automotive and aviation, due to their high strength-to-density ratio. Their strength and light weight is quite desirable in engine crankcases.
