RE: 3W 80 Xi
Dick, no panic, this motor pulls well and I am happy. I have a good feeling it will out pull my old ZDZ 80 RV. The wrap around header you mention, they can be had already from 3W, the Aluminum Double Bend Header made for 3W. was looking at those.
Also Razorback I agree if I am going to put a can on it I want some power back because of the extra weight incurred. The BMB look good but its to bad they don't take credit cards. Also, what about the 3W tuned cans for their motors. Do you know if they add power, or do they just make it quiet. Price would be better!
If I went with a tuned setup I would use the 3W Double bend with the KS 1090 or maybe the 1080. I like the tuning thing, but I also have a budget to keep[]
But it would be cool to be able to turn a 26-10 at 7000 RPM

RE: 3W 80 Xi
If were to use this motor on an in-cowl in a CHP extra would I be ok in the sportsman class and still have power for 3D fun? I would probably put a can on later. My buddy is going to do the same airplane with a da 100. Is his going to be dramatically more powerful?

The CHP Extra is very close to the size of the plane I am putting together now. If they are 22-24 lbs with the in-cowl muffler it will be fine for the sportsman class, or 3D. What are they weighing in at? Also at this weight the 3W would have an advantage over the DA, lighter is better, and the power would be just fine, perhaps almost as good as a DA. I have not flown mine yet so can't say for sure.
The 3W tuned canister looks good! Not much more money than a in-cowl muffler, you will gain some power, how much I am not sure. 200 rpm or more would be worth it I think. I am thinking of going this way if I can sell the Super Sonic. If the all up weight of the plane is getting closer to 24+ pounds I would go this way for sure.
If you put on a tuned pipe it would be as good as a DA 100 for sure, and still lighter, but the cost would also go up, still not as much as a DA 100 all set up.
What to do!

RE: 3W 80 Xi
Well something else to remember when comparing the 3W 80Xi to the older ZDZ 80RV. The 80Xi has a long stroke, compared to the ZDZ. This would make it less efficient at turning higher RPMs like the ZDZ, and it does keep up, however it would be able to turn bigger props because of the increased torque of a long stroke motor.
This is why this motor can turn a 28-10. It would be interesting to try a 28-10 on the 3W 80Xi and then on the ZDZ 80 RV. It would be my guess that the 3W will out pull it!
I have both motors, set up the same way, and will try it as soon as I get my hands on a 28-10
Also the new ZDZ 80 RVJ has even a longer stroke than the 3W, should be interesting to see how it runs.

RE: 3W 80 Xi
Well they are both wide blade props, the Biela is actually a 25.5-10 and the Bolly wood is a true 26-10. The Biela is a little wider, not much. I would guess about the same load.
I would try the Biela on the 3W however it is drilled out for ZDZ 4mm prop bolts, the 3W uses 5mm. Still want to use the Biela prop on my ZDZ. I would try the Bolly on the ZDZ but its in for service at this time.

RE: 3W 80 Xi
Recieved my ZDZ 80 RV from service and put the Bolly wood 26-10 on it, it turns it at 6100 rpm. Put the same prop on the 3W 80i, it turned it at 6300. Both motors running on pitts type mufflers. The 3W is not fully run in yet, only 1 hour run time, the ZDZ has over 200 flights on it but now a new crank, cases, and bearings, was flown for 1 hour easy, both motors run on the same day. A very cool day at that[&:]

RE: 3W 80 Xi
I find that vibration levels in the ZDZ and 3W are about the same, both very smooth for big singles.
The midrange in the 3W was crisper, it would spool up very fast!
The tilotson carb on the 3W is a lot more sensitive to low end needle tuning. If it is just a little to rich the motor would not keep a consistant idle and the rpms would always pick up a little. Set right it was very good, like the ZDZ. The ZDZ was not so touchy, but it was a little harder to start in that it would flood easy. The 3W was very consistent at all times, very easy to start.
Both very good motors, the 3W is stronger by a few 100 rpms, 1/2 lbs heaver, but I like the 3W setup more.

RE: 3W 80 Xi
Just talked to Bobby, he says the new 3W 80 turns a 27-10 at 6100 right out of the box..Don't know what muffler or prop..And the price will probably be going up..A word to the wise

RE: 3W 80 Xi
Yes, as stated, I was turning 6300 RPM with a 26-10 Bolly Wood, not bad considering it was a new motor, Supersonic muffler, and very cold out.
I have heard that you can gain a few 100 RPMS with the 3W Tuned can. On a nice warm day I could see it turning 6100 on a 27-10 prop
I just hope it will be as reliable as my trusty good old G62

RE: 3W 80 Xi
I am complaining the other way
ZDZ is too expensive.
It's the same euro so I don't know why one would be almost 20% more expensive...

Because the ZDZ 80 RVJ is super
Don't complain or they may raise the price on the 3W 80

RE: 3W 80 Xi
Would anyone please post some pictures of how your 3w-80s are mounted, I have a Wildhare Extra 260 and will be mounting my 3W-80 during the Christmas holidays and need some ideas.

RE: 3W 80 Xi
rcairflr - I have the same combo but don't have it mounted yet. Wanted to let you know though that I talked to Bobby at Cactus Aviation and asked if the motor is supposed to come with a mounting ring. He said, no, but that he is having some made up. I believe they should be ready by about now. He also said if using stand-offs to make sure not use anything longer than 1" because of vibration. In the info I received with the motor it talked about building a motor box but the pic shows just a flat piece of ply and then stand-offs attached to the ply. Bobby also to make sure the carb in an enclosed area; so if it is in the fuse past the firewall it should be fine. He said the reason is because of varying/changing pressures in the cowl. I asked him about using an air cleaner and he said to just use a single thickness of pantyhose and a rubberband over the velocity stack. I know this doesn't address your request, but thought the info might be of use. Good luck on the plane/motor. It should be a nice setup.
