As an unsolicited endorsement I would like to compliment Adam on a great product. He built up a Homelite 49.5 for me and I am extremely pleased with the engine, It is a real powerhouse! I was hoping to get it airborne but some health problems have delayed that for a while. (Getting old is a real drag!!) I did get to run it and was amazed at the brute power available! Didn't get a chance to tach it as my nurse (read "wife") chased me back to bed, but hopefully I will be up and around by the time the weather turns flyable.

I hope you get feeling better soon, Phil. I'd like to read about how that engine flies your model.

SPE40 gas enging are able to fly Giant GeeBee Y plane like this one . 97'wingspen, takeoff weigh are over 20lb , use 22-8 bolly CF prop turn over 7000RPM on the ground . the satastic thrust are about the same weigh as the plane has. you can find this plane at thiefaircraft.com or winnerrc.com

Can the spe 26 mount the prop with single bolt or have to go with 6 bolts?

You can do either. The main prop bolt is very substantial in size at 10mm but If you wish you can drill your prop for a 6 bolt mount set up. For those of you who may have a hard time beliving how small and light this engine is check out the photos below. The photos are my BCMA 26 and a brand new Saito 125 four cycle glow engine. They are pretty close to each other in physical size. My engine on the left weighs 38 oz. (with ignition) and the Saito 125 weighs (32 oz). My engine has a built in engine mount but you would need a mount for the Saito 125 so that would add another 4 ounces at least so in reality there is only 2 ounces or less difference between the two engines. Plus you will have a torque advantage of the larger displacement gasoline engine all the benifits of running gas. This engine is amazing!

Hi Ed,
Thanks for the well wishes, they are appreciated.
My G-Shark had about 200 flights with a US41 that I had installed a Walbro carb from a Quadra 52 and a Bennett muffler. Very impressive performance but not a 3D candidate.
I tried a Quadra 52 with EI and was not much better. I hope the BCMA 49.5 will stir things up a bit! Just a matter of fitting it in.

Keep posting! I enjoy your comments.

Hi Adam

That looks impressive. Is that 38oz of SPE26 include muffler? What is the Saito 125 weight with muffler. I believe you are refering to Saito 120 right because 125 is listed at about 25-26oz at Horizon site. At any rate, I'm torn between the SPE26 and Brilleli 25GT.

Can you give us more picture of the 6mm prop mount vs the 6 bolt mount? Judging from the picture, you mean I can use a single 6mm bolt or couple with other 6 smaller bolt? Wouldn't the single 6mm bolt a bit too small?

Sorry, I'm a noob in gasser. The Roto or G26 etc are all using 8mm bolt for the prop.

Read BB post again. He said that the main prop bolt was a " substantial 10 mm."

It was when we were in Toledo that Adam took the picture of the 26 next to the Saito 125. We weighed both engines there with my postal scale, so the weights he is giving are correct. Both engines were weighed RTF with mufflers and all. It is hard to beat the SPE 26 for weight.

These engines have a 10mm prop bolt, not a 6mm. The BCMA 26 and BCMA40 share the same size prop bolt as what Fuji uses for the 64cc engine. The reason for this is to make it much more resistant to modlers stripping out the prop hub threads. The prop hub is designed and provisioned for the ability to use 6 small metric cab bolts to be used to eliminate any possiblity for prop slippage. I think doing this is way over kill for this size of engine. The main prop bolt is more than adequate for securing the hub. One of the next changes will be drilling this main bolt and tapping it for 10-32 threads for easy Aluminum spinner installation.

Comparing installation weight between my BCMA26 and a Saito 125, there is hardly any difference with the Saito being about 2 ounces lighter which is negligible, but the BCMA26 will have a substantial power advantage over the glow 4 cycle engine.

Do not discount the Brillelli 26cc engine. This is a fine engine as well and an extrordinary value. I have helped build these engines with Scott and there is a lot of fine detail work that he does to squeeze more power out of these engines. He spends a lot of time on each engine and they are meticulously inspected and tested before they are shipped out.

I am glad to see you got those pictures of the SPE-26 and the Saito 125. I could hard;y believe the small size of SPE-26 and when you put it alongside the Saito that really made it for me. I have e-mail you a couple of time and I was wondering if you received them? I am really looking forward to putting that SPE-26 on the Super Chipmunk I got at the Toledo RC show with you. I bet you are as busy as Scott right now so get back with me when you can

Thanks

As far as prop mount bolts, I have decided for my application (in my extreme flight yak), to use the main 10mm bolt and only two of the smaller bolts in the 12 O'clock and 6 O'clock positions. That way, I am getting extra rotational strength without using all the bolts.

Anyone running their SPE26 yet? I am having trouble getting mine to run correctly.

The walbro that came with it had both needles turned out 3.5 turns and the manual states they should be turned out around 1.5. I tried running the engine with both settings (and settings in between) and can't get it to run right. I can't get it to start up or "pop" by hand either. I need to use the starter on it. It definately is primed with fuel and after about 30 seconds on the starter it will fire up. It seems to idle somewhat high and rough, and when I attempt to move the throttle past 1/2-3/4 , the engine dies right away.

My carb as I mentioned is a walbro and its the one with no choke. The carb has "1814" stamped on it. There is a picture a few pages back with the engine mounted on my Yak if that would help.

Basically I am looking for some starting settings and advice as to why I can't get it to run right and why it won't hand start.

Thanks.

What is your low speed needle set at now ? I do not know what it should be but I can help you get it there. If it dies imediatly when going from idle and advancing the throttle, it is lean on the low. Go a little richer and try it again. A good place to start is about 2 turns out. Every carb and engine is a little different, but it should get it going. A correct low setting will also make hand starting easier. Also some break in will do wonders. but back to tuning, richen it up a little at a time on the low until you get a good responce. Too rich and it will load up. It takes a little time. The high is more like a glow. Peak it and richen it up a tad. But one thing to remember on gas is the low needle effects the high quite a bit. If you change the low, the high may need a little adjusting again.

SIREX

If you go to BCMA engines website they have a owners manual that has all the info you are looking for. Adam has done a real nice job with it. It is in PDF format.

Hope this helps.

Scott;
I ordered my Brillelli 46cc EI engine today. I hope you can figure out all the instructions I put down. I'm sure I will be getting an email about it(LOL). Can you give me the mounting width so I can go ahead and install the Dubro 120 motor mount or should I wait.

sirex, thanks for the advice about the manual, but if you read my post you will notice that I tried the settings recommended from the manual and the engine won't run.

Set your needles to the factory settings and use an electric starter. Some of my engines will hand start right out of the box while others need the persuasion of an electric starter. After you get the engine going and needles set and run the first tank of gas, it will hand start from there. I have not encountered one yet that won't start by hand after doing this. Poco is right, that a little break-in does wonders.

Feel free to give me call and I will assist you in any way I can.

Adam,


I hope all is going well with shipping out my new SPE 26. I'm looking forward to getting my hands on it to see how it all looks and feels. I plan on puttin it on a P-26 Peashooter as I think it will be an excellent substitute for a 1.20 that the kit recommends. I'll keep you posted on the progress once I get it going.

Thanks,
Scott

well, i got back from vacation and tried out your suggestions today for starting the SPE26 engine. I started at the suggested settings from the manual of around 2 turns out on both needles. The engine would hesitate mometarily and then die when I tried to throttle up. I gradually backed out the low needle until I got a smooth transition from idle to full throttle.

It seems to be running fair right now. The only problem is, I have the low and high speed needles backed out 5 full turns! It doesn't feel like it is excessively rich either at this setting. Any suggestions as to what is going on, or should i plan on running the engine at this setting? It just seems that I had to back those needles out an aweful lot. Its not running great right now, but it is manageable. I am using medium diameter fuel tubing with a three line setup to the tank if that helps. Also, I am using the same fuel/oil blend that I am running in my DA50, which is premium gas with ashless oil at a 40:1 ratio.

Any other input would be appreciated. Thanks.
