CS 3-W are they worth it????

[T. Bob]

OK
Here’s the scoop, I don’t know the answer, because I’m an Idiot.
Are the CS 3-Ws really worth the extra money?
I have a QQ (i.e. CS) 106 and it’s a monster, but are they all worth it?
Or are we just paying for some red cylinders that don’t dissipate heat very well?

Thank You

For all of you DA guys just go back to your ****.
Oh wait, you can’t read anyway.

Anything 3W is worth it.

CS series are definitely worth the extra money.

[ShortBus]

It costs more....

...must be better!

[stommerd27]

You get what you pay for.?

[Stu_D]

Those of us who have a CS its worth the extra coin

and for the rest of us who prefer to see the proof of

extra performance ,more revs ,more torque and a smoother

engine its hard to pass up the Classic because so far I havent

seen a thing . But thats just my opinion .


As you may of guessed I have A Classic , its only a single spark

and I am very impressed with what it can do . I fly with a mate

who has the CS and I would pay good money to anyone who

could tell which one of us is using what engine .

They are the 170cc engines .


The CS TS does seem to have some merit though .

I recently took a DA-50 out of my bipe and put a 3W 55i-CS in its place. I;ve only had about 4 flights with it so far, so I really haven't seen the engine come into its own, but...

It definately idles and runs smoother

It definately runs HOTTER.. I hope this settles down soon. I added baffles under the cowl that were never needed on the DA-50

I'm using a 22x10 on this motor, had a 22x8 on the old one... max rpm's are about equal on the ground.. 6800 (the CS should get better as it breaks in, still running rich)

The 3W will vertical lift the 19 pound bipe with no problem. The DA-50 would eventually stall (that's why I decided to try the 3W).

Was it worth the extra money... hard to say. I got what I was looking for in pull-out power, so from that standpoint, I'm happy.

T. Bob,

Don't do it man. Dale and I built two extras a few years ago and slapped in the QQ 85 twin. They were like buying duds from the firework store. It was a tuff year getting them to run correctly and the support from who we bought them from was below average. You are correct they also ran hot and needed baffling that the originals did not need. We quickly sold both planes and chalked it up as a sick loss. Just ask Fick, He bought one of the planes and sold it about a year later. I said the same thing about getting what you paid for and went all out to have the cool looking red cylinders blinging from the cowl. IMO, it just wasn't worth it.

OK Craky
lets hear it.

I don't really like to advocate 3W here in the US - the service and support are infuriating (although I should give Gerhat and Aircraft International credit for trying, I think they are just too small an outfit to help all 3W users in the US - they will need to eventually).

However, the engines themselves are not matched, as far as I;ve seen, by any other available in the same class (I can't wait to see a new DA 100 run next to a 3W 106, or the DA and 3W 170's compared). I have had 4 3W twins, the first a Classic 150, the second a CS 150, the third a CS 157 TS, and a CS 170. I still have the 157 and 170, and I can tell you for certain the CS upgrade makes a difference. Bottom line, it's a little lighter, a little smoother, a little more powerful, a little hotter, and a lot more expensive.

Seems if you want a little better you have to open your wallet. All 3W's need to be baffled and tuned well; the CS engines have an even smaller margin for error, but perform like one would expect a hot-rod engine to.

When I ordered my 3W212b4 from Gerhard he kept me from spending the extra money on a CS. I was told the stock 212 would be fine and he was right, runs like a dream, gobs of power. A 212 is just 2 106's bolted together! I am sure there are other differances but stock runs fine for me.

[sweetpea]

I've got the CS 157 and its a beast. I have 2 stock 106's and they run great also.

I was told that if you are going CS don't waste your money on the single cylinder engines as the most important thing is the matching. There is nothing to match on a single.

[smokin]

the cs difference is in the hand selection of the parts and their fit to the other parts. if i understand it correctly, the cs is like a "blue printed" engine. the ports are polished and the tolerances are tighter. now, i wish that the cs heads weren't painted red due to the heat holding. but, i have been flying 3w's for some time now and i know how to properly baffle a cowling to keep them cool enough.

Painted cylinders cool just as efficiently as regular cylinders. Just because they read hotter on laser temp guns, that doesn't mean they are actually running at higher temps..

[smokin]

i realize that they aren't running any hotter.... paint holds heat though! the fins take that much longer to cool when they are painted,,,, thus everything inside the cowl, i.e. ign... gets hotter right along with the fins.
