Default CS 061, I give up...

I usually like to tinker with engines but I'm now giving up on the CS 061. I have actually flown it quite a bit but never gotten any really reliable performance. Today I actually saw bubbles coming out of one of the mounting lugs, so that's it I have had enough of this engine now. I have attached a photo to show the problem, the casting is porous and it connects to the inside.... [:'(]

Now that I know it I can actually hear a hissing sound as I turn the engine over...

OMG!

Isn't that like "drop-fordge" type casing, maybe it's just a lemon?


What's it look on the inside of that, anything?

Come on Man!!

You give up too easy!!
Just have the case powder coated, or maybe chrome plated and you'll be right back in business.
The biggest casting flaw I've seen since looking at an iron skillet made in Bangladesh, is the hole in the side of a CS piston. Evidently they're put together by folks getting paid per unit instead of being paid by the hour?

I guess when you have bubbles coming from a mounting lug, it's time to "pull the plug".

Ok, here is picture of the inside, sure looks like a bad casting to me, guess I'm lucky to only have one hole to the outside.
Guess it is a lemon, or rather a "rotten" lemon since they only make lemons anyway...

I know it doesn't alter the fact that it is a lemon... but can you not fill the holes? Impregnate the holes with say ,, JB Weld?

Well, I don't know anything about casting aluminum or iron. Back in the old days the technology was crude and cracks were common. The Ford engines were ground smooth to alleviate the problem somewhat. Imagine paying guys to stand there all day detailing blocks and heads to that degree nowadays.
Anyway, how does a quality manufacturer see to it that the castings have good density and no air pockets? Is there always a certain amount of rejects?

If only all "rejects" were rejected, though...

Cant you drill and tap it and grind it down to fit? Just the hole I mean?...Rog
the CS engines arent much on power anyway, I know I have one,,pretty but for shelf only....

Well I guess it is possible to seal with some JB weld, wouldn't take long to do, and then maybe it could match the power of a Queen Bee...

You could put the case in a jar full of solvent, tape it to a vibrating sander and "sonic clean" it. Change the cleaning fluid a few times. Methanol, alcohol, MEK, all seem to break down the oil pretty well.
General Electric has a paint called Glyptol that is a favorite of high performance engine builders to paint the inside of engine blocks. It's primarially used in electric motor shops.

Aluminum solder is supposed to be able to do the job, but I haven't tested it out yet.

I have used aluminium solder on other parts and I find it a little tricky too use. There is not flux that removes the oxidelayer (as there is for welding), instead one has to scratch inside the melt with a sharp object. Once through the oxide layer they it does seam to fuse together but it is rather unpredictable and I only get rather lumpy results. The few parts that I have soldered all needed JB weld for sealing...

Okey, no one wants to be called a quitter so I thought I would take it a part to clean it and see what I could do.
Turns out that in an effort to save weight the case is actually made from aluminium foam? [X(]

The crank also has some hardened swarf on the inside, never seen it that bad before...
So it appears to be a lemon crank, in a lemon case, all packed in a fairly nice red box.

Well at least they still make the best bird's nest soup. It always goes good with a side order of Black Fungus [that's what they really call it] !

All I can say is: OMG!

Thank you posting the pictures and relating your experience Mr. Cox. I certainly feel for you in your wasting your money on this POS and then investing a substantial amount effort in trying to get it to run right - and then to discover just what it was that you were trying to work with.

You can take solace in the fact that your post will likely be a big "heads up" for any poor soul that happens upon this thread in their search for information on the CS 061 engine.

I had seen the earlier post (from CP I think?) regarding the major void in the piston, and I thought it was most likely an isolated example.

I cannot imagine that the importer/vendor of the CS 061 is not also very well aware of the quality issues with this engine. How he would continue to offer them for sale I do not know. I would think that his credibility as an importer/vendor will be significantly damaged because of his continued sale of this engine.

A little update, I used a dremel to clear and clean the cavity and then filled it with JB weld. Deburred the crank and put some JB weld in the front there too while I had it all ready mixed anyway. Gave it a another run today, seems it has picked up about 1800 rpm or so at the top end...

It now spinns an APC 5.7x3 at about 18000 rpm [X(]
(3 head shims, OS#8 plug, "mousse can" muffler, 10% Nitro)

Low and midrange are really rich tough, they are best at 1/2 turn on the needle while full throttle needs 1 turn. It has always been like that no matter what I do.
There is a Viking funeral at the field tomorrow, could have tossed it in there but it looks like I might give the engine another chance (tenth or so).

Give it another chance or give it to me . Never give up until I obtain some acceptable performance of almost anything.

Seriously now, there must be some alternative to fix the bad casting.
