Hello,
Thought we needed something to discuss. It seems to me that all they have to do is bolt a DA150 topend on to a slghtly enlarged case and shaft. It souldn't take so long to debug it, as most of the parts are already perfected. Could it be they are doing a new engine from scrath? Does anyone know what the price will be?

All speculation on my part, but I'm sure after all the troubles with the DA50, they're going to do everything possible to get it right the first time on the 75.

FYI, 3w is coming out with a 78 single very soon, its half of the new bad ***** 157, should be a perfect fit for those 33% planes.

WOW! I wonder were they will put the carb. Most likly in the rear.

While we discuss engines that don't yet exist...where's the ZDZ-105 single? Half the 210 twin.

i imagine it will be in the rear, I bet it will be one strong motor, if its anything like their 157.

The 3W78 would have the power of a Sach 5.8 with the smoothness of a smaller displacement.

I bet it is as strong if not stronger than the zdz 80, which would be great to have another engine in that category.

After what happened with the 50, I'm sure they want to do a little more testing before release.

More competition in that cc range would be good.

How about a DA25, DA75, DA100 single, DA100 4cylinder, DA200 twin, DA200 4 cylinder, DA150 6 cylinder, DA300 4 cylinder etc........Maybe a 5 cylinder 4 stroke radial ?
Might as well make the rumors cover more sizes
You can guess all day long, NOTHING is coming out until DA makes an official announcement...
There is no SANE reason for all these different sizes...Why not concentrate on making what IS being sold the absolute best ?
Ever looked at all the different sizes sold by 3W ? Why so many ? Maybe they should concentrate on better QUALITY control instead of using their customers for testing new models...

Hi Ralph,
3W is like me, they build engines based on what ever parts and blocks are available at the time. This should get a response

Quality control? reliability issues with 3w? dont even go there, even DA has had this with their new 50s. At least 3w is coming out with new motors. Their 157 is the cream of the crop for 150s, see one run and you will believe. I do want DA to come out with some new stuff though, curious to see what comes out in the 75cc area and 150cc area.

Quality control STARTS at the machining level and continues until delivery...The QC I'm talking about is at the machining level, and things that should not have gotten out of the factory...
In defense of 3W, the new castings are gorgeous, its about time......Now if they will hire some inspectors

.....for a nice "bench fee" of course.

Does anyone have pictures of the insides of DA engines? It seems like everyone sends them back to DA, so we never get to see the guts. Maybe this is by design.

I have never had a warranty issue with 3w, so wont go there. I do hope that DA comes out with more motors, if they come out with a better performing engine, I will switch back to DA. I flew DA before 3W, and would switch back in a heart beat if they made a better performing engine. Rumors have been from DA, an 164, 82, 75, etc. I wish they would at least say, we are not committing to a date, but we have plans for motor X in the future.

I bought a used 3W-106 with a transferable warranty. It had a porous crankcase and ran a little funny because of it. Cactus Aviation replaced the crankcase with a new one. No charge, no bench fee, nada. As it should be. I've received excellent warranty service from ZDZ and DA too.

Flip and Fly

Well ZDZ just came out with a new improved Black ZDZ 80, lookup, look way up!

If ZDZ has a new 80 and 3W a hot-rodded new 78. DA will have to do better than a 75 if they want to steal the show. Nothing like rolling out a new engine that will be "one upped" before it even gets out of the doors. Maybe DA will now need to design a 80 or 85cc cylinder for a 160-170cc twin and single cylinder engines to satisfy the power hungry flyers out there. From surfing RCU, I can see there are many pilots who would buy these more powerful engines just to stay ahead of the other guy on the flightline.

Quality control?? Throwing a motor together with spare parts??

Well lets see, DA probably doesn't have the time to R&D and bring a new engine to market...they are too busy performing warranty work on the endless stream of 50's that are being sent back in for the latest and greatest "updates" and bearing replacements etc etc...

The same ones that send their motors in over and over will be the first to stand behind the pulpit and preach the "good news" on their dependable DA...and at the same time UPS is trucking their little motor down the interstate for the second or third time I wonder if that's why they needed to raise the price tag on the DA-50?? Ya know with all those free man hours and parts and all...

I won't disagree that they have the best service in the industry...they had better as much as ya'll need it!! LOL


I REALLY bet this gets a responce hehe ...I love the brand loyalty war threads, they are so fun to read, I just figured I'd participate for once...It was fun

A 75 makes sense -the cost of doing a completely new engine is daunting.
The new ZDZ80J is completely new - bore /stroke/rod / porting system completely different
That means a complete re design of every piece in the engine.
That means if the the power increases (and it really did) the price must increase .
No free lunch ----
Here is a funny one for you -- the new Fords-
The 500 is really a reworked Volvo chassis-nicely done
The model which will docompetition with the Toyota and Honda (good luck)-has parts which interchange with ---Mazda.
If you can be competitive with off the shelf parts - more power to you.

Seriously, it does look like DA has gotten the bugs worked out of their 50 and should be able to focus on something else.

It looks like they need to step it up a little if they're gonna compete with these two new motors from ZDZ and maby 3W. I've seen the pics of the ZDZ (and it looks sharp), but this is the first time I've heard about the 3W. It wouldn't suprise me though, they are always coming out with something new.

I hope to see DA do something, competition is a really good thing. One thing I know for sure. Wether it's the most dependable engine ever made or if it takes a dozen updates to fix problems they won't be able to make them fast enough.....and we all know it will be the prettiest
