Fired up my DA 50 yesterday. First impressions
Well, I have read about these engines for a long time. Thursday I got a chance to see for my self. First I really hate the rear carb and the pain of using another servo for the choke. But I really dislike the standoffs. When I started it you could tell that it was torquing something fierce. You could see it twisting against the firewall. I was using a Mejslic 23/10 at the time. Power was superb! -- Swinging that beast at 6300 RPM! Needles were good right out of the box and let me just say this engine is a work of art. How does it stack up to the rest of the engines I have owned over the years-- I have owned a few.
It gets the edge over my Taurus 3.2 and Brison 3.2 in power. I believe the rear induction is the reason for that. The DA is lighter by a bit. There is a lot less mass with the DA. The transition from idle to full power is exceptional. However the Taurus is MUCH, MUCH smoother at idle and does not try to twist the firewall off of the plane. I think this has a lot to do with the rear bearing in the Taurus that the Brison and DA do not have. It also may have to do with the large bell mount of the Taurus as opposed to the long standoffs on the DA. Price of the Taurus and DA are close with the Brison being a bit less. I had to wait 5 weeks for the DA--but hey- I had to wait 6 weeks for my Taurus-- you can get a Brison anytime. Bottom line is that it is all a matter of choice and preferances. At this point if I had to do it all over again, I think I would have gotten one of Ralphs Cunningham's G62s--Still (in my mind at least) the best bang for the buck. My first impression??? I don't think I will be selling the DA anytime soon.

RE: Fired up my DA 50 yesterday. First impressions
I have the same impression of mine, I haven't started mine yet because it is not even on the plane but I sit it on the fireplace mantle and make noises.. I love mine, even if I have to just stare at it right now.

RE: Fired up my DA 50 yesterday. First impressions
IF THOSE ARE YOUR FIRST IMPRESSIONS Then (stupid caps lock, sorry) your going to be amazed when the DA~50 FULLY breaks in. In a couple of gallons richen up your bottom end a wee bit (1/8 to start) and you'll notice your idle smooth out, and at 5 gallons when you go to 100 to one Amsoil again, it will get seem like a different engine. Did you balance your prop?
I have seen the DA 50 smooooth as silk on idle when broken in, and My Brison (5 gallons) 3.2 runs better than my DA right now....not for long mind you, but much better throttle response.
This I attribute to more time needed to break in the DA.....obviously.

I'm lovin mine and got into the 2nd gallon of break in gas today. now that I mounted one I can easily do it again. The power is incredible and if it gets better than all I can say is wow. I found that I need to ballance my prop.

To stop your plane from rolling away try little pieces of silicone fuel tubing on the axles to apply pressure to the wheel hub.
Or when you say walking do you mean rocking at idle?

Engine continues to get better with each run-It is getting smoother and continues to impress- With the 22/10 the walking is not nearly as bad. Thanks for the suggestion, but the wheel pants are a pain to get off. I think I will live with it for a while and may try it in the future.

If I pay 40-50 dollars for a Mejlik22x10 prop I hope it is balanced. I haven't even checked the one I've got.[8D]

The big bell mount of the Taurus is relatively heavy and makes the engine difficult to mount on a smaller firewall. The side mount carbs really need a velocity stack to work properly in my opinion. Vibration is often a function of mixture in a new engine. You should not make a final opinion of overall smoothness until the engine is run in and leaned. Most threads about the DA do not complain of vibration.

Isn't that the entire purpose of a Carbon Fiber prop? It is supposed to be hollow for light weight and they just inject some epoxy in the light side to balance it. Look closely you will see the filled in hole on back side of the prop. $80.00 for a prop - I better be paying for something!!!

Amen RickP, I got curious last night and put the Mejlik on my robart balancer and it was perfect, now whether I got lucky or not I would think paying 45-60 for a prop the company could at least balance it for me, so anyway it was ok..

RE: Fired up my DA 50 yesterday. First impressions
I checked both my Mezjliks on the balancer when I got them...both were spot on.
I probrably won't in the future tho, unless I have nothing better to do.
Heck, that would cut into my online time...

I'll bet ya a hot dog and a Coke at the next IMAC that it is not balanced[8D]. If you put that in a good balancer you'll be surprised. I have YET to find a prebalanced prop that is actually "prebalanced". I've checked Mejzelik, 3W, Menz, Fuchs, Bambula. Not one was balanced.
It's also a good idea to balance the hub also on larger props.

RE: Fired up my DA 50 yesterday. First impressions
In defense of the Taurus I have to say The bell mount was designed to distrubute the load over a greater area. The fact they still use the rear bearing will alow a wide variety of thick heavy props without tearing up the ineards. And I don't have to bore out a firewall.
I have also seen and run the NEW design of the 52 for 05.No increase in weight but more power. This I understand is incorporated in all their new engines.
I'll keep my Taurus's. Very user friendly and now have most in stock.
