Whats the deal with these engines? Are they really any good? That is a @#$% load of money for them. Is is really worth the wait? I think BME is much better.

UH-OH,
Look behind you, Bill & Mike may be ready to pounce.

Good call jemo.

Hi finnz,

>>I think BME is much better.

Why?

Bill

I thought I saw you in the shadows.

I think it is cooler looking and it is lighter and it has the best power to weight I have seen. It is the smoothest running engine I have seen to date as well. How bout them apples.

Here we go again. Agree with jemo, already suscribed to the thread and ordering pizza. I want to know how a cooler looking engine flys better? The party is at my house. Pete

Hi finnz,

Well first, let me know which model specifically you are talking about. From your previous posts I didn't think you owned one, but that you were talking about getting a 50. Have you owned one?

>>I think it is cooler looking

That's pretty subjective, but you're certainly entitled to feel that way. I happen to think they both look great, but looks, except for quality, doesn't really enter into my engine buying decision.

>> and it is lighter

You are correct. Are you talking about the 44 or 50? The 44 is about 4oz lighter than the Taurus 2.6. The "new" 50 is about 1.5 oz lighter. The "old" 50 was 1.5 oz heavier. I believe Taurus put the extra couple of ounces to good use. It's in their bottom end design. Have you seen one?

>>and it has the best power to weight I have seen.

That is definitely open for debate. The numbers my new Taurus turns are significantly better than the data I've seen posted on the 44(including the numbers from the two I have owned) and mglavin's broken in one(s) are about on par with the best BME 50 numbers I've seen posted. The Taurus 3.2 turns about 400-500RPM more than the 2.6 on equivilent props.

>>It is the smoothest running engine I have seen to date as well.

Again, which one are you talking about, and is it one you owned or saw run. I have owned two BME44s(they are excellent motors) and they are not what I would consider smooth, not even close to the Taurus. I have heard the 50 is smoother, but I have not seen one run in person so I can't compare it to the Taurus.

Bill

My Best Friend in the world just got his yesterday. It ROCKS!!!!!!!!!!!!!!!!!!!!!!!!!!! I am so darn impressed I might go and buy TWO!!!!!!!!!! Put them on a P-38. 27lbs Can you believe it. WOW!!!!!!! BME 50 by the way BILL, I have made a lot of calls to some top guys. They are all for the BME's in the smaller classes. Best Power to weight Yet. I am not a spokesperson for BME. Thay just Rock.

So does that mean that they have a good beat & are good to dance to? :spinnyeye

finnz,

I'm with EJB on this one. I've got nowhere to go with this.

What I will tell you is the BME 50 is a good motor, and when you get the two for your P-38, I'm sure you'll be happy with them.

Bill

I have a BME 44 Swinging a APC 20-10 @ 7600 on the ground and only have 1.5 gals. in it,

Would it be a good Ideal to try a 21-8 ? My PW WM Extra 300 Weighs 15.8 Lbs.

I would like to slow it down a bit but add more thrust

I did try a Master Air screw 22-8 But was only able to turn 6000 on the ground.
Any Help from you BME 44 Guys would be Great.

What brand is the best too.

Hey FINNZ,

I have had both the BME 50 and the TAURUS 52. The have the exact same size prop shaft (7/16) and because of this, I was able to do some side by side testing. My results were that both engines would turn the same prop WITHIN 100 rpm of each other. This testing was done from BRAND NEW all the way up to each engine having about 4 gallons through them.

What does this say?......
They are pretty much the same. The BME is a tad lighter and LESS EXPENSIVE while the TAURUS is a smoother running engine which is friendlier to the airframe.

I am a big fan of BME, in fact I am within the first ten to get the NEW 55 EXTREME when they come out (I ordered 2), but I also wouldn't hesitate to get another TAURUS!!!

I don't have mine anymore. I sold it with the H9 Edge. I still have my Fox 2.4 and love it. I also just got a ZDZ 40. When it warms up I will see how it performs. I was very happy with the power of the BME. The only reason I went overboard on this thread was because Bill always goes on and on about the Taurus. That post was a year ago. Wow..

and the winner is?





lol

Taurus -- of course---somebody has to replace Bill :>)=

We need someone to do the 50cc shootout with DA-50, BME-50, Taurus 3.2, Brison 3.2, Fox 3.2, ZDZ-50.

Same props, open exhaust, and same muffler.

How bout one of you high-$ flyers out there in the golden state?

For a true comparison the engines that were mentioned will have to be classified, for example
cast crankcase vs machined crankcase
cantilever crank vs fully supported crankshaft
And that is just to mention a few things not including fuel, oil and ratio of mix. Time on the engines or new out of the box. and of course the props.
But the final straw would be a true dyno test under controlled conditions.
Good luck to whoever has the time and $$$$$$$$ to do it.
