See what you guys and all of your talk have done to me. My funds are officially depleted.

I have a 3W-170 CS on the way though, with a set of K&S 95 cans to go with it to make up for my lack of money in the bank.

Sometimes it is OK to be broke; this looks like one of them. I'm sure the wife will love it. I got my wife a table saw for Christmas once; she seemed pleased.

LOL that's funny. Kind of like one of the guys at work that bought his wife an ice auger for Christmas.

Congrats...You will enjoy it!! had the 157CS for 3 years trouble free and the new owner has flown it for 2 or 3 yrs. trouble free. Once broke in they are very smooth and of course very tough to beat in the midrange.

Just bought a 3W-56CS myself a week ago and I see they have new numbers on the ignition. I believe it said 3W 3.1-1...Perhaps another upgrade from the 4.4 version..

I plan on running an A123 on my ignition seeing as they are rated to use 6.0 to 7.4 volt batteries. I really like the fast charge capabilities of the A123 cells.

Should have sent me a PM. Could have saved you a couple of dollars. The CS is a little over rated so you pay more for it. The difference between a CS and a base engine is how they check the parts coming out of the parts bins. Those colored heads are pretty though

Congratulations on the purchase of an excellent engine!!

Excellent news Doug.
I am sure you will be very pleased with it.

What airframe is it planned for and what prop do you have planned?
Those of us that have "seen the light" here ran ours in on either the 29/12 3blade or 32/12 2 blade Mejliks and I have recently changed mine to a 30/13 3bl Evo after seeing another guy here with that same combo on his. That change has happened after the engine is run in and the plane it is in is a Composite Sukhoi.

You realise now that you will not be able to look back down the ladder without a wide grin on your face.

Thanks for the info guys. I was a little undecided about the CS but ended up going for it. Kind of liked the picked out peseta and yes those cylinders do look nice. For a prop I have a mix to try of Mejzlik, Xoar, and Falcon. Sizes 30x12 and 13, 31x12, and some 32x10's. Engine is going into a Pilot 42% Edge 540 in the Matthais Dolderer GSHOCK scheme from the Red Bull races. They charge a tidy sum for these engines, but in the long run I think it will be worth it.

Now you make it hurt....[:@] The Pilot Edge holds the #1 spot on my play list. There just isn't a better flying plane than a big edge and Pilot did it right. Jody has a few of the Compy 2.6 versions but I just don't have the time and money to do another CompArf.

Mate, it is fine sitting and fondling something like this while you realise you can't afford to eat anymore
Good for you Doug!!! You will really like this engine

Grats!!!!!!! AI or Cactus? 32x10 is a good overall prop.... any smaller and you'll be ripping at over 1/2 throttle.... my bro had a 30x12 bolly wood, and the tips were slightly eaten away from so much prop rip

Thanks all, I'm getting really hyped. It is from AI, Cactus is gone. Gerhard had it all shipped out within a few hours of me placing the order.

Pat I still remember the loss of your Edge. She was a beauty. I have been flying a 100 cc AW Edge and it is a blast. Nothing will do a KE spin like an Edge.

i didnt know cactus was over with..... just curious, what oil and ratio will you break her in with?

I run Redline in everything including break in. I do richen it up to a 32 to 1 mix though. Takes a little longer to seat the ring but I am in no rush. My other engines that have been broke in this way run like a top and the inside of the cylinders look like mirrors.

3w's brreak in just fine with a synthetic. A little extra is a good thing.

Doug,

Which Edge do you remember? There were two, and both wnet to a wing loss. One the wing folded around the tube and the other had the tube break inside the middle of the fuselage. I was REALLY partial to the first white prototype. BTW, nothing tumbles like an Edge either. You can do pinwheels when you have everything right.

The one you lost last year or is it two already? It was a Wild Hare with red and yellow on it and a white base. Like the picture below. If I remember didn't you do a build thread on it or was that the prototype?


I am at home for a few minutes so I can post a photo of the scheme I got. Been out camping and haven't been able to with my phone.
Here is a photo of a couple that I found on the web that the same scheme.

The prototype was more than two years ago. Tom sent me the second one (Red Bull) to function as occupational therapy after beginning to recover from paralysis picked up from overseas work.

You are going to like that 170 VERY much. Just don't try to wind it up looking for max RPM. 3w's don't work that way. MVVS as well. They can develop more RPM but they do that well after they pass the peak of the torque curve. That peak is where you want to operate because it provides the best power and efficiency Think comparative to a diesel. They make their best torque at a lower RPM when they are carryng a load. When kept in the lower gears they PUUULL! If you prop larger to remain within the upper limits of the torque curve you'll find your plane will keep pulling a vertical for a very long time after the other guy's 170 fell out of the sky.

That is some of the very best advice you can follow - these engines are real stump pullers and they don't need to scream to make thrust.

Every single example I have seen where people are "unhappy with the power" (once they have them tuned right) on these has the engine under propped because they think maximum RPM is all that matters - it definitely isn't for the majority of our purposes (Racing excluded).

Yup I am being told this by some online friends as well. They are saying to go with a 32x12 to a 33x12. Dang looks like I need to buy another prop.

It showed up in the mail yesterday. I must say with the CS the painted cylinders are some sharp looking. I am going to set it up on a test stand so I can get the needles set before mounting it in the Edge which has yet to be shipped from China. Probably will not fly until next spring.
