Trying to answer my own question I found this in Flying Giants forum right after I posted my question.

MLD-28S or MLD28S or MLD28 comes as side mount muffler version. It is now available. The "R" or MLD-28R or MLD28R will be available in July. The R version is the rear muffler mount version.

Additional information:
MLD-28S is not a SPE-28. In fact there is no SPE-28. As of today;
MLD => MLD-28S
SPE => SPE-26, SPE-43 and SPE-40 has been discontinued, but still serviced as of May 2008. SPE-43 is the official replacement (parts are not fully interchangeable) for SPE-40.


Peace,
Steven Chao,

BCMA was selling SPE 26CC engines and have now stopped selling them and others and changed there inventory.. But the SPE that is spoke of inthis thread is the same engine that Cermark is selling..

I do not know who Cermark is or who Adam is except as I have learned by reading. You are obvioulsy paranoid Flyer.

I found info from a forum that is not RCU but folks who fly big (Giant) planes and was hoping to find out what is really going on in the small gas arena. RCU edited my post automatically to exclude the name of the forum but I was not offended though I thought it was petty.

I was particularly interested in the 26 and 40 SPE engines as well as the Brillelli 26 and 36. Weight was one of my main criteria. I have several pages of notes from my reading of RCU, MFG sites and others. I always thought that the low end of gas would be 50cc ( I have an 80cc YAK).

After many hours of reading RCU I am now convinced that a quater scale plane with a 26-40 cc engine could be a real good 3D and extreme aerobatics performer. Thanks to all of you who have talked about small gas engines. And thanks to RCU for advertisements that have led me to more information.

So Flyer, I will continue my research on small gas engines to use in quarter scale planes (I have now done quite a bit of it) and ignore your foolish nonsense. This will be my final post in this forum and certainly my final communication with you.

We will be offering the BCMA-28 Pro very soon. This engine is in fact the Cermark MLD28S but we will be selling it with our ignition system and possibly with a larger venturi carb offering a slight edge in performance over the stock engine. Our ignition unit alone will make this engine! I have the website built for this engine, I just don't want to post it until I have them available. So far it's the shipment that never seems to ever get here so until I actually have some, I am not offering them. It is close and it may happen this month but don't hold me to that. I really don't know much more than any of you at this time.

The MT-42 is exclusively distributed through BCMAEngines therefore we were given the permission to sell it under our brand name. It will still have the MT name engraved on the back of the crankcase. We have made some improvments to the fit and finish of the engine but its a real performer and will rival many 45-50cc engines. This engine is well designed and well made and will work well in 3-D planes under 14 pounds.

No need to be defensive. Above is your closing signature. A person will surmise from this that you are with Cermark. No harm intended.

Good luck with your search! You are more than welcome here!

Hey Guy's! I Googled Steven Chao, Cermark and found my suspicions to be true. I think he put Cermark after his name in the second post out of habit. He is with Cermark, and actively promoting sales of engines from Cermark. He is not a harmless individual that I have offended.

RR24

Flyer,
I think the only reason it showed up as Steven Chao, is because he copy and pasted it from another forum here on RCU about the MLD 28 that was wrote by Steven Chao

If I can borrow something from Heritage Rider: He has at the bottom of his post:

I am just getting into Gas engines and am confused on how to size an engine for a plane. How do you determine the CC's that are right for a plane. For example, I was talking to some of the old timers at my club about the Goldberg Extra kit that has a wingspan of 68 inches and is rated as a 60 - 90 size plane. Some say this is a good candidate for a 26 cc. Others say it should have a 20cc. Then I was looking at a 70 inch Extra and that was a 40cc candidate. What is the formula? if it is a 60 2 stroke / 90 4 stroke - go with a 20 to 26 cc? If it is a 90 / 120 - a 36 to 40? and a 1.80 use a 46 to 50 cc? It doesn't seem to be specific to wing span. Is it wieght and wingspan? This is confusing.

You said it. it is confusing.. I still havent figured it out. i had the spe 26 CC gas engine in my Twist 150 and it barely would fly it. Put a gms 120 in it. nitro engine and now it screams through the air. the GMS is 19 CC and lighter. But now i have a 26CC gas engine for something else i guess.
But will go with something smaller to put it in like a 60~90 size plane.. Still very confusing. But best thing to do is research a plane you want to put an engine in. and go with the recomended size engine for it. or find forums were others have experimented with larger engine like the twist 40 and an OS 61 FX is the best combo it rock that little plane.

But i have a P-51 60~90 that i'm currently building and its big enough for the 26CC engine to fit on. But i'm going with an OS .61 FX For weight and it will fly more scale i'm thinking.. But i seen another Twist 150 with the SPE 26 CC in it and it flew ok. about like mine did. and have seen the engine one other planes in the 120 size.. But usually the manufactiure of alot of gas engine will sometime have a list of recomened plane that the engine will work good with.

But the best thing to do is research the plane, and if you want to overpower it find others who have done it. I found out the hard way that experimenting can get expensive..

Funny thing is i have a 28% Extra 330L with a 45CC engine in it and it screams has major power turning a 20X10 prop wing span is 81 Inches. others that have the same plane are powering it with a 50CC engine. So its weird how engine matching works i still dont understand it fully..

OK2Fly

I just look at the overall weight and what prop the gasser will turn, and compare it to the nitro engine that the plane manufacturer recommends. If the specs are similar, then I'll go for it. Asking on the forums helps a lot too.

karolh

For gassers in the 23 - 26cc range I use 900 sq. ins. of wing area and an AUW of 11.5 lbs. as my min. and max. criteria for good aerobatic performance.

My 68" span Goldberg Extra flies great with a Ralph (RC Ignitions) converted to EI G23 at exactly 10 lbs.

Hi, fwiw just maindend my Multiplex Big Lift and thought I should sheer the video with you, ws 8ft, engine BCMA SPE26 and MAS 16*8.
It will need a bit of tweaking but pulls the Big Lift with authority.

Thanks Paul, It is Multiplex in Germany (I think). Saw somewhere that it is no longer in oproductin.

Hi I just ordered the 42MT. from Adam at BCMA I'm going to be puttting it on the Seagull extra 260 (1.80) size what do youall think of this combo?

linkadrip

Eastkurt thank you for the link to the plane i like that plane wish i had one for my SPE 26.

Sorry for any inconvience, the video has been edited and I did not know that the link was changed.

This should be a nice combo. Seagull makes a slightly heavier, more solid bird, so the 42 is ideal by weight. Post pics if the install, if you can.
