I am putting together a plan for this fall/winter project. Going with the basic retail barring sales and such Brison is at $449, BME is at $499 and DA is $549. Now I have seen all of these run and those who own them have no complaints. From my chaiir its an apples/oranges thing and go with the cheapest which if I did will still not sacrifice quality. Opinions

YES!!

Pick one, be happy.

I'm not a big fan of the Brison's. Especially if they have the timing ring. BME, DA, or 3W are my preference.

I have the BME44 and the DA50 and really like them both. My friend has the brison and it seems really good. Good luck in your venture into gasoline flying. I love it and really can't seem to get interested in glow engines at all. What plane are you going to build? BTW, everybody loves cheezypoofs!!!

Joe!~)

The Brisons are fine engines, all will fly your plane fine

Going to put it in the Pacific Gee Bee Y.

All of the engines listed are fine... And there is nothing wrong with the mechanical advance on Brison engines. I have a four year old 3.2 that runs great! It's not hi tech, but it is pretty simple and very reliable... Hopefully I'll get an airframe for my DA-50 this year, and I hope it becomes as predicable and reliable as my Brison...

Greetings,
I have both the Brison 3.2 and the DA~50....the Brison is so strong and dead steady reliable, that when the DA~50 breaks in I'm expecting a better engine. Hard to imagine, that.
Both right now start on the 3rd flip after 4 choke flips, every single time, regardless of weather or temp.
The Brison at 5 gallons has remarkable throttle response and transition. The DA is improving with every tank, 1 gallon thus far.
As you can tell I love them both.
However without a doubt, if I were to spend the money tomorrow I would get another DA. Lighter (proven) and more power promised.
Hunnert bucks?
Break it down into months....how long am I keeping the engine? 10 months? It's easily worth 10 dollars a month more to own a DA.
2 years? 4 dollars a month to own the DA~50...no brainer. Resale?
Check the history of engines sold here on RCU...how many Brison's....How many DA's?
DA's hold their value like a Mercedes Benz...
How about service?
DA hands down.
I don't know a soul who regretted buying a DA~50, do you?
Anyone ever hear of someone wishing they had bought ANY other engine over the DA~50 they had bought?
Nope.
Kinda simplifies it doesn't it?

I have a Brison 3.2 that runs like a sewing machine at idle (super smooth) and has very good power too. For your application take your pick and have fun!

I have aBME50.3 flips choke 3 flips start.Great motor.Brison ,ZDZ,and DA I think they are all pretty much the same.

Well. . Backafter30. . .to answer your question. .

" I don't know a soul who regretted buying a DA~50, do you?" Regret, no, Prefer NOT to. . yes.

I am replacing all my 150's, including my DA150 (Already sold off), with the BME110. . .. .And I am MUCH happier with this engine than ANY 150. . .I'd do the same in a 50cc powered plane, and would buy the BME50 first and always.

Please note my first post was "to buy any one you want", but since you want to make this a "Sales Rep" contest, there ya go. The BME is the BEST 50 out there. . .makes the same power, if not more, than a DA50, weighs a couple of ounces less, and costs less, AND it uses a beam-style mount instead of those silly standoffs (remember the weight quoted for the DA is WITHOUT the standoffs. . ). It also uses a single-bolt hub versus the tedious multi-bolt hub of the DA (where the bolts can break or shear), and the side-mounted carburetor is a lot easier to access and adjust.

So what if it's a "weedie conversion" It's step by step as good a motor as the DA50. . .for the extra money and "Development time" the DA should be light-years better than anything out there. .Sadly, it's barely equivalent to the "weedies" From BME.

I have/had owned all 3 -- All are great. FLIP A COIN! I personally do not see where the DA is much superior to any--ESPECIALLY FOR A HUNDRET BUCKS MORE. Actually, my personal favorite is the Taurus, but you may have a problem getting one.

It's the customer service that the company provides, starting with the very first phone call that sets DA ahead of the competition. Parts availibility. Service turn around time. Bench charges.
Ask these questions to all 3 companys.
Service during and after the sale are just as important as reliability and preformance, to me and many many others.
Even Kris will admit that DA's service is second to none. (For John Q. Modeler with no connections)
A HUNDRED BUCKS MORE?
Worth every dime.

UH. . "If it don't Break, it don't need fixin." Backafter30. $100 to have the privilege of being told "send it in and we'll fix it" is a bit steep in my book. For the extra money, you expect a LOT more performance too. You just don;t get it, sorry.

I have to agree with Kris^ and AJF--2 on this one. I just can't justify spending the extra $100 on the DA when my Brison 3.2 starts right up, NEVER skips a beat and makes great power. I have a BME 50 that I have yet to run but the others at my field run reliably and are very strong. I'm sure the DA is a fine engine, but so are the Brison and BME.

I have had a Brison, seen a BME and Taurus, the Taurus was impressive power! More than the BME and Brison, probably the closest competitor to the DA, which I would easily spend $100 more to get. My .03

That's funnyKris that you mention "weedies".I bought the BME because my echo weedeater.trimmers,blower and chainsaw.Never miss a beat!!!I belive if my info was right that the BME uses the sameengine as Echo.Only dif is the prop hub ,carb and exaust!Am I wrong?

It's kinda pointless to argue the merits of all these small gas engines. I worked in that industry for ten years (Homelite) and then I tested Chain saws for the Gov't for another 5 years. That's 15 years worth of looking at a hell of a lot of small gas engines. Some are better than others but typically not by much. Weight is important but only to a point. Power is important .. again only to a point. Customer service is very important. If your happy with what you buy then you made the right choice. If your engine does not run well some thing is wrong because it should. There is no one "Greatest" engine out there folks.. be it BME, ZDZ, DA, Brison, Taurus.. all are good engines. That's just the way it is...

I think it is worth mentioning that the one big difference with the Taurus is the rear bearing that the DA, BME, and Brison do not have in their design. You pick up a tad in weight but the exchange for smoothness at idle is a biggie. FWIW

AJF--2,

I believe the BME 50 has a rear bearing.

I Like DA's service, if something ever happens to any of these engines you will be better off with DA's customer service... 2cents

Come to think of it, I believe you are correct. It is the rear induction cantlever models that do not have the rear bearing-- except for the Brison, which does not have a rear bearing either.

The only thing I could ad would be this....if it's going into a Gee Bee of any kind, go light on the front end, they love to nose over. I am getting a BME fo my project, only cause a buddy is selling it and I know the history. If I got a new engine, it would be a DA, only because the designed and built it from the ground up for airplanes. Others are modified from the lawn world. Nothing wrong with that, just that thay have a little extra weight. All are good reliable engines.

a rear bearing has no effect on idle smoothness, or lack of..A good cantilever crank is actually stiffer than the other type...

I always liked the hyperbola about the double cheek smoothness.
A cantilever crank actually has an excellent bearing layout for prop hub rigidity.
But the discussions were fun.
