BME 55 REANNOUNCED!
Looks like BME has reannouned the 55!!!
2.1 lbs without ignition and with rar mount.... Looking good and supposedly April release.... I'd look for more like summer... :) http://www.bmeengine.com/html/sneek55.htm http://www.bmeengine.com/gfx/55/55pic2.jpg |
RE: BME 55 REANNOUNCED!
'Bout time. When it hits the skys there will finally be another engine for the DA and 3W 50cc class engines to follow around.

RE: BME 55 REANNOUNCED!
i wanted one of these a few years ago now i am content with my current stuff. should be nice on a 1/4 scale bird, get rid of those gas guzzling glow jobs if someone has that deal. I don't own any more 1/4 scale. well my ear will be here to hear about the deals....

RE: BME 55 REANNOUNCED!
For all those who think a single bolt prop hub is not enough, LOOK at all those neat tapped holes ;)
Just think, you can put at least SEVEN bolts through your prop !!!!! :eek: Even more if you make a new top washer...:D |
RE: BME 55 REANNOUNCED!
Cute. In fact much of what you say I find amusing RCIGN1.
But I suppose you KNOW that it features a couple different patterns so you can repurpose props already drilled for other engines... And of course you are not forced to use any but the single center bolt. Or maybe the center bolt and two opposing bolts. I guess a fella has options... I like that. And if the stated RPMS are true... 24x8 Bolly at 7200 and 24x8 Menz at 6500... it'll be a real powerhouse... How much do those converted G-62 weigh? And they spin a what how much? Nevermind... it's not even worth considering. :) ORIGINAL: RCIGN1 For all those who think a single bolt prop hub is not enough, LOOK at all those neat tapped holes ;) Just think, you can put at least SEVEN bolts through your prop !!!!! :eek: Even more if you make a new top washer...:D |
RE: BME 55 REANNOUNCED!
wow i did not look at the RPM data[8D]
It will be nice when they hit the streets because the streets know the truth! |
RE: BME 55 REANNOUNCED!
Ain't that the truth!
I love my DA50's and they are great engines from a great company, but I am not so narrow minded that I won't consider and try new offerings that offer substantial benefits. 1 lb less is the obvious benefit and if it spins the same prop at even the same rpm as the DA, then I'm all for it. There are several airframes out there (and more coming) that will benefit from this puppy... All the new Performance Series from Great Planes: Ultimate, CAP 232, Yak54 and Edge, Giant UCanDo3D (with rear carb model), Aerotech Yak, H9 Extra 260... are just some that come to mind. These planes just don't make for a good G-62 home. Converted or not...

RE: BME 55 REANNOUNCED!
I'd like to know where it saved the weight compared to other engines of this displacement. Sure looks as heavy as everything else when staring at the outside....:D
Maybe a few photos of the internals would help solve the mystery? How bout some rpm#s with a Menz-S 22x8? |
RE: BME 55 REANNOUNCED!
My guess is that it will spin the Mens 22x8... around 7200... but only time will tell.
I wanna see an NX 23x8 on it... or the MSC 22x8... My two favorite props... The head's cooling fins are lightened a great deal. Just like the 110 Extreme. The "nose" of the engine is also fairly minimal, as is the prob hub and washer. The connecting rods, crankshaft, might also be a n ounce or two lighter... it all adds up. |
RE: BME 55 REANNOUNCED!
i figure if they could do it with a 110 compared to the products out there, this was a easy move looks to have the cylinder of the light weight 110.

Hey Maudib. it was in jest..I guess you just don't know what smileys are for :eek:

RE: BME 55 REANNOUNCED!
ORIGINAL: Diablo-RCU I'd like to know where it saved the weight compared to other engines of this displacement. Sure looks as heavy as everything else when staring at the outside....:D Just a few of my observations as to weight saving. The snout on the larger engine is shorter/smaller than others on the market The carb/reed block is lighter and not metal integrated as part of the case The machining in non critical areas seems to be more extensive The jugs are more compact The engine is generally more compact A little hear and there, I guess all adds up |
RE: BME 55 REANNOUNCED!
If I read the other thread on this engine correctly, the Bolly 24x8 was on a cannister & the Menz 24x8 was with a standard muffler.
This engine " changes the rules" for the 50cc class of planes out there. I can't wait to get mine. Just imagine, all those 50cc planes out there being 1 lb lighter! ORIGINAL: Maudib Cute.

RE: BME 55 REANNOUNCED!
There are a lot of 50cc airframes that will be difficult to balance with 1 lb less in the nose... all the WildHare, Lanier and others will be challenges... as they sometimes are with "standard weight" 50's.
Still where there is a will... there is a way. Can you imagine an Extreme Flight 87" Yak at 14.5 lbs? A Precision Aerobatics 28% Edge at 13.25 lbs? A GP Ultimate at 13.5 lbs? It's promising, but I'll reserve judgment when they actually ship and are being installed.

RE: BME 55 REANNOUNCED!
I agree J. David, I'll make a judgement when I know an independent flyer gets 50 gallons through one without a hitch. I'm concerned with durability at this weight. I can think of many ways to accomodate a lighter 50cc on the common airframes out there. 24" props? Seems a heavy load for a 50cc class engine. I'm sure there will be many people here with the engine when it comes out. Looks like an industrial head on a widdled down aluminum case, cool! When I see it on the deck day in and day out on hot days etc that will be interesting.
The way BME handles this engine in customer service will be very interesting and once in the public sector these normal events will become transparent to some extent. I hope for the best, but I am a die hard DA fan of their engines, service and personalities. They know how I fly, and have equipment and service to suit my needs, I have doubts any other company can equal of match their level of quality. BTW I can imagine what a 50cc size plane would be like at 12 pounds! haha! I'd like to see 11lbs 1400sq in.(dreamin) Joe Kelley |
RE: BME 55 REANNOUNCED!
This could get me into Gas motors.[8D]
|
RE: BME 55 REANNOUNCED!
I bet this motor on an OMP Yak or Edge would get you right around 12lbs or so with 1632" for the Edge and 1580" for the Yak. This motor should rock.

RE: BME 55 REANNOUNCED!
Now Joe, you know it's not possible to build a 50cc plane with an all up weight less than 12 lb...right !!;) |
RE: BME 55 REANNOUNCED!
Yes Ron, but, you are quite exceptional! :D

RE: BME 55 REANNOUNCED!
i am good at coming in 1-2 lbs heavier than everyone else :D

RE: BME 55 REANNOUNCED!
Hey Keith, this is the engine I originally wanted to get for my Wild Hare. I have the Ultimate and i'm thinking this could be a good match for it. The airframe likes a light engine and this fits the bill. I'm at 5000 ft., what do you think would be a good prop for this engine at this altitude? Does the bolt pattern match a ZDZ or is it more like a 3W? That carb also almost looks like the one I have on my Evolution 58, know the model name and number?

RE: BME 55 REANNOUNCED!
It looks like all of that styrofoam cylinder head research has finally paid off. 2.1#'s I hope the ups guy notices it floating against the ceiling.

RE: BME 55 REANNOUNCED!
I personally jumped onto the list. I have had a 110 running on JMB canisters for 2 years. It spins a Mejlick 28x10 6800rpm and pulls 54lbs according to a fish scale. So far the thing has held up great. From what I can see comparing it to a DA 100, the light weight comes from many things.
The overall length of the motor is shorter. The stroke is shorter, this makes the jugs shorter, the connecting rods shorter and the counterweights smaller. The machining of the case is much more detailed with metal removed from every crack and crevis The cooling fins are thinner (overheating has not been a problem) If the 55 is anything like the 110, it will be great. My father is a die hard DA fan with 2 50's (one of which seized up), but after seeing my 110 had to order one. To date he loves it. A guy I fly with has a DA150 (which also seized up), and was originally a nay sayer, but is now changing his mind as well. He says when BME makes the 8lb four cylinder 220, he is going to ditch the 150. He may be waiting a while for that one though.:D |
RE: BME 55 REANNOUNCED!
I'd be a 100% BME guy if they had more to choose from, but it looks like they're going that route. Like I said above, I originally wanted to get the 55 extreme for my WH Edge, but I'll be needing an engine for the Ultimate and I wouldn't have to re-engineer anything. The only downside is that I'd have to get another fuel can since the 55 takes different gas than what I put in the Evolution.

RE: BME 55 REANNOUNCED!
Ben,
Keith at BME is not a mass production kind of guy. From what I've seen, he'd rather take the time necessary to make sure it runs the way it's supposed to before releasing a design. I know that he's "hands on" with every engine that gets shipped, so that would limit production capability some. As for your Ultimate, using a light engine like the 55 would eliminate the need to move batteries under the canopy floor. You would have to install them more forward, and that's a good thing. The power available would be awesome! Pat |
