Spoon feed us a little. What about a link to where it describes the engine?

aussiesteve

Lighter than what?
More powerful than what?
What is it's torque curve like?
What are the REAL power figures like (not made up numbers for the advert - actual figures, especially in the RPM range where you fly).

From the information I have been given, they are not a bad engine. Typically chinese Manufacture (being made frmo a lot of off the shelf parts - which helps down the track should you wish to repair it). Mostly good out of the box.
Are they the most powerful in the 55 - 60cc class? - Nope
Are they the lightest in the class? - Nope
Are the power and weight numbers for it acceptable? - Most likely depending on what you wish to use it in and how you wish to fly it.

Buy one, try it and report back. there is very little actual true experience posted on the threads about it so far - someone needs to impart that info for the next person that asks

Geez, you're starting to sound like me

aussiesteve

You have no idea how much of a compliment that is to me.
I guess I have learnt well master

Isn't it funny how the world goes around.

Some time ago, I saw a post from a person that I look up to on engine knowledge. He was thanking another very experienced engine man for getting him involved in these engines all those years ago.

You are one of the people that I look up to in engine knowledge. (hey - don't get to big headed - you ain't the only one).

Yah - Well I look up to all thre of you as I'm many others do to. Thanks for the continuing education guys.

I've received two RL58 to repair , both with serious damage caused by the small bearing used on crankshaft.
When the rear crakshft bearing fails, and take too much play, the big end needle bearing breaks, and broken parts of needles causes serious damage to the engine.
I think manufacturer must change this small bearing.
The engine is much lighter than DLE55 because all main parts are ligther. Crankshaft, rear bearing, crankcase .....

That sounded like some serious advice to the manufacturer. Bearings only fail for about 4 reasons, one of them being grade quality.

Steve,

Thank you, and yes, when the process works the way it's supposed to it always does come full circle.

Two out of how many?
Some years ago Bryson had a few front bearing failures. But alot of it was due to poor breakin.

I don't know how many RL58 have been sold in my country because there are no oficial dealer. But i think a few units.
Maybe both engines have failures by a poor break-in, but i'm sure small bearings on a big bore engine is not a good idea.

Brison lost the majprity of their bearing failures due to impact damage. The evidence was clear when they were returned for "warranty repairs". Almost all the cranks had sustained some form of damage that could be seen during the tear downs. Unfortunately the engine owners elected to lie about what had happened with the engines. I had on of those that failed a bearing but it had experienced a few prop strikes when mounted on a GP 1/3 Pitts.

Off topic here a bit, but will prop strikes sometimes/maybe/always cause bearing failure? I've had a couple broken wooden props on my DLE55 from rough landings/flexy gear causing the tips to hit while still running, and yesterday did a bone head move in the pits where the prop hit while running and the nose went down, resulting in a 22" prop becoming a 12" prop [&o]

I can't speak for all other engine makes but you should have nothing to worry about with the DLE, there has been no history of prop strikes leading to con-rod bearing failures that I've seen. Impacts with Terra firma though have caused many main bearing failures, you can feel the effects in your hand while turning the engine over with the plug out.

Thanks, Jody. You saw first hand a real impact my DLE55 had last year, and replaced the bearings for me, as well as a few other necessary parts. I've got 3+ gallons thru it since then, and all is fine, but have had the above-mentioned "prop strikes". Thanks for the info.

kerwin50

Yeah those prop strikes can play on these big gas engines not like some of our little 40 an 60 nitro motors

Needle bearing failure, where have I seen this before.

I had talked to the manufacture about this engine and was sent information about how much stronger and better it was than the other popular China made engine and that it had been tested for over two years in China.

Looks like I was being feed a lot of propaganda. LOL

Translation for propaganda == Bull Crap

Has anyone else had bearing problems with this motor?

BadAzzMaxx

Needle bearing failures has been the most common problem in China made engines, Some have tried to correct it other do not care.

If they have only been a few of them sold and are already having them to fail, what does the future hold for them.

They just will not spend a extra $4.00 for good needle bearings. ???


Try one out and see if they hold up for you.
