They have been there all the time, but all the advetising hype by those that could afford it, and all the talk about "great service" by the other guy eclipsed that fact. Nobody's ever exclaiming the virtues of great service if they never have to send an engine back.
RTK and I were having a conversation about engines the other night and he brought up a good point. It may be perhaps better for newbies to obtain their first gassers from companies with "great service", or all the others that are on the low priced side with the "copy cat" engines. The reasons you ask? Here ya go.
A newbie can do about anything they want that's wrong to do and send the ruined engine back to the "great service" company for a full, free rebuild. That's a pretty nice financial cushion for the new guys that don't know what they are doing or fail to read directions. A little hard on the company perhaps, but the customers will always have a back stop to protect them. Then again, eventually the "great service" company will have to raise the price of their products to offset a large percentage of those returns. That won't matter because they will already have the market convinced that their engine is the only way to go. As for the "copy cat, borrowed design" engines, they are low enough in cost that when a newbie burns them up or stuffs them into the ground they aren't out nearly as much as they would be for a higher performing, higher cost, engine.
Once those newbies gain a little experience in what they are doing then they could move on to bigger and better things, having gained all that experience at relatively low risk levels. As their experience levels go up there is much lesser need for factory service for two reasons. Number one is that the engine quality of what they stepped up to is superior to what they had in the beginning and don't break nearly as often, and number two is that their understanding of engine operations, thrust, rpm, prop selection, and the useless hp values provided by some manufacturers will have increased to the point they are no longer doing all the things that always wreck an engine. By that time they will have also finally figured out how to install a switch in an ignition system!
Awww, never mind, that was all just speculative and sarcastic thinking

you got your point across,i don't let little things bother me like spelling,were not in school and were not getting graded on it,the idea here is to get the info out there,all people do not speak and read english.
ENJOY!

Balsa Steel:
I'm where your at. I'm about ready to start the Yak now. Winter is coming. No BME55 -- it is the perfect engine for my project and its not here...and yes, I've been one that has been complaining. sorry.[
]
So, I'm not convinced about the DA50. DA50 advertises 14-18 lbs. I expect my plane to come out 17-17.5Lbs....thats the ragged end of the DA. I'm not really convinced on the Taurus...I don't see folks getting that much better numbers out of it then the DA, and when you price it out with them they actually want more than the DA--So thats not gonna work for me. I fly 3D not warbirds....so I don't think a G-62 is the right engine either.
I have heard that I should go with a MVVS58. I'm sure the MVVS58 is gonna have more power than the DA. My question is will my Yak fly ok at ~18lbs, 1380sq feet wing loading? How do I calculate wing loading or what do I compare it to know if its right? [&:]
PS...Balsa, did you get your DA50 from gixxer01? [:@]

Yellow Aircraft P-47. Not a small or light plane. Taurus 3.2 (52) swings a Zinger 4 blade prop at 7,200 rpm to drag it around in Utah. The reason I mentioned the state is becuse not much of Utah has seen sea level since the day of the dinosaurs. Agreed I don't know the specific size, and Zinger is not the best prop around, but it's the one flying that P-47.
7,200 rpm with a 2 blade prop would be pretty reasonable numbers for most 50cc engines.

Yeah, I bought gix's DA 50. I'm used to a heavy Funtana gasser, so I'm no where near spoiled to a light 3D plane with ballistic power. And I haven't seen any complaints from any DA50 powered KMP Yak owners. I'm not a numbers man, so I'm not going to beat myself up over wingloading and power loading, but let's face it, these KMP's are heavier than they were designed to be to begin with, and adding more power to overcome the weight is just going to add even more weight, and flight performance is going to suffer directly. Like the saying goes, you can't polish a turd LOL. I wanted a BME 55 because of the lighter weight, but I'm sure this plane with a DA 50 will be more than adequate for me. If it were me, and it was within my budget I'd hold out for one of Extreme Flight's new 50cc birds. That way you're not starting out with a weight penalty right off the bat, and you're closer to the ballistic power to weight ratio you want without loading the wing with an oversized engine.

1380 in/sq divided by 12 twice = 9.58
18lbs times 16oz = 288oz total
288 divided by 9.58 = 30.06 oz per sq/in
Not bad, I think anything at about 30 oz per sq/in is not bad for 3D.
I would not go any higher than 31 oz per sq/in if possible.

RE: Last call BME 55
I just haven't been that impressed with the DA50's that I actually see on planes flying as opposed to reading. I see folks hovering at 50-60% throttle....and I'm not sure I would brag about that. Plus I kinda want a motor that I potentiall could grow into a 30% if possible.

RE: Last call BME 55
I fly alone out in the country, so I don't know any more than what I read, so you're probably more right about the DA 50 than me. 60% is a LOT of hover throttle for a 3D plane. My Funtana is probably 40-50% with the 26GT, but since that's what I'm used to, the DA-50 on the Yak should be OK for me. You may want to scope out that Brillelli 60cc for yours. It's supposed to be decent for a 30% plane too. Just a thought.

I figured I better ask about the 55 again. Any new news? Will they be out by spring, again?
I figured I better ask about the 55 again. Any new news? Will they be out by spring, again?
And, honestly, at this point, I'm glad I did because I did some research and what you need to buy is the Brillelli 366, 60cc. You can buy one of those today---right now! Thats 5 more cc than the BME 55, 10 more cc's than a DA50, and it RTF weight is ONLY about 2 ounces more than the DA50 RTF weight is with a SlimLine pitts muffler (the muffler many DA owners use). http://www.rcaerobats.net/GAS_ENGINE_WTS.htm. All for probably $100 less than the DA50.
And whats the BME55 really going to weight RTF anyways....no one but the manufacturer can weigh it?

RE: Last call BME 55
I would look at the 55 as something that's not going to happen. There's nothing at all wrong with either the design or the performance, but the developer feels that there are probably enough 50cc class engines already vailable and therefore can't justify another engine in the same calss, regardless of any differences in weight or power.
It's pretty hard to argue the point. Just how many people would jump on a new design for just a couple of ounces of weight difference while tossing in the never ending power debates? If you can't sell a thousand or more in the first production run it's not worth the cost and effort in the long run.
