RE: SYSSA 30CC GAS MADE IN USA
Mine is mounted in a Hanger 9 Twist 1.50. Turning an APC 18x6w prop. No torque problems throughout the rpm range, on stock exhaust. Some people need to to fully read others post's and not turn them into a "general" practice sort of thing.MTK is working on pattern use his his tuned pipe and prop mods. He obviously seems to know what he's doing, and has done so safely. He has not blindly posted his process for others to attempt. A certain individual has also questioned whether he has ran the "other" 30cc engine. As far as I can tell you haven't ran either but jump thread to thread to stir the pot.

I'm glad to hear the syssa will transition good with a 6 pitch and stock muffler on a lightweight airframe Actually the apc 18/6w is a good prop But gas motors do not turn as high rpm's as glow If the Syssa will turn a xoar 18/8 at ~7500 with stock muffler and decent transition then it is doable for 1/4 scale 3D imo I'd really like to see that If it doesn't perform this well then change it Todd lol You need a minimum for gas powered 1/4 scale 3D... jmho I think the 18/8 is it The 19/8 kicks boo-twah:D\ Honestly if the Syssa 30 is just a little less power than the DLE 30 it may be very good for 1/4 scale aerobatics.... i.e it may have less vertical but if it accelerates a little slower during rolling circles etc. may be better The DLE has power to spare Of course it depends on the airframe a bit |

The APC 18X6 is the same load as a Vess 18X6 and is the best overall prop excluding warbird props. The Syssa likes the higher rpm range, ask Todd. He said it runs best above 8000. What I was saying is, The Syssa is not timed to spin loads that will run in the 7000 rpm range, ie 19X8 without a tuned pipe. Relax already. |
RE: SYSSA 30CC GAS MADE IN USA
It sounds like it turns an 18/6 WITH a tuned pipe so a 19/8 is completely out of the question anyway imo
I guess an 18/8 is out of the question too.. too bad try a 17/8 on stock mufflers or pipe;) |
RE: SYSSA 30CC GAS MADE IN USA
When broken in...an 18x6 Vess will turn 8700-8850 rpm on stock muffler.
We'll have to test an 18x8 on the stock muffler to see...should be around 8000 or so. About 1/2 gallon through an engine here with ES pipe and 18x6 is now 9600 rpm. I'll have to test the 19A, but I think the pitch of the 19A is more than 6. |

"We'll have to test an 18x8 on the stock muffler to see...should be around 8000 or so." See, now that sounds fine especially if it has decent midrange strength I haven't heard hp numbers and have only heard about 18/6 props on a pipe Hate to see fellow modelers disappointed[8D] |

RE: SYSSA 30CC GAS MADE IN USA
I don't care about a fixed HP # do to the fact no engine produces the same power in the same range. One engine might be a speed demon, the other could be a stump puller, or another might be a good combination of both, but not be the best of either.

RE: SYSSA 30CC GAS MADE IN USA
I was at an electrical surplus store and I was thinking that it would not be that hard to make a dyno. They had lots of DC motors in the 5-10 HP range and with the proper reduction drive to get it in the correct RPM range and you could measure HP directly from the electrical output, since 745 watts= 1HP. You would have to calibrate it for the conversion efficiency/losses of the motor, but that is not that hard to do.

RE: SYSSA 30CC GAS MADE IN USA
Has anyone heard any news about when the Extreme Flight 78" Extra 300 gasoline version will be shipping? I ordered my second engine from Todd (I'm not pushing until the rest of you get your first), and I did pick up the carbon pipe Todd said they will be using with the EF Extra. The Extra is supposed to have a tunnel for the pipe, I'm really excited about flying this setup. My Funtana weights just over 9 lbs all up which is considerably lighter that the Extra at 12 lbs, but if the pipe boosts the thrust close to 50%, then this should be a rocket! I rode a Honda CR-125 when I was a kid, that bike had an explosive transition when it reached a particular rpm. We always said the bike was peaky, but the usable power band seemed to span a large rpm range. It will be really interesting to see how this affects 3D flight, particularly hovering.
My Syssa Funtana is sitting in the basement waiting for a reasonable day for a maiden. I'll hoping to fly something this weekend, but with highs in the mid 20's and winds averaging 14mph, it still doesn't look good for the maiden. If I get ambitious, I'll fire up the Syssa and send you all some video, otherwise you'll have to settle for pics of weekend progress on my Stinson build. |

I haven't flown the Syssa/ES Pipe combo yet, but I wouldn't worry about the pipe being peaky. I have run the ES50G and ES55G and they are great. CR-125's are known for being peaky. They are set-up for top-end power. You can get different types of pipes for different kind of power. We used to do a fair amount of work on 2-cycleQuads. Lets just use a 250R for Example. You could get a Pro-Circuit and a FMF Fatty and the two would make the power come on different. The Fatty was designed to producetorque and the Pro-Circuit high end. So the Fatty was a good choice on a extended swingarm hill climber and the Pro-Circuit was a good choice on a race Quad. Sorrytoget off subject, but my point was that pipes can beset upfor different purposes.The ES pipes are purpose built forRC Aircraft. There is a lot of tuning that is involved, but luckily forusthework is alreadydone for us. Ed and Toddhave been working on the right combo.Guys keep in mindthese are not GLOW motors. Gas motors have beenproven torespond verywellto pipes for3D Flying. |

RE: SYSSA 30CC GAS MADE IN USA
Guys ,
It would be good to see how the motor performs with the stock muffler. I want to use it in a warbird and the larger the usable prop witb a high pitch the better . It is all very well trying to get more out of it using a pipe , but that is not much help when a lot of us want to be able to use it just as it comes . |
RE: SYSSA 30CC GAS MADE IN USA
I'm sorry but that was starting to get kinda funny! [sm=tongue_smile.gif]I have the stock muffler on mine and I would love to give you some numbers but its to wet and cold to run it at the moment. Todds first post was intended to give us an idea what she will do with and with out a pipe. [sm=biggrin.gif]

RE: SYSSA 30CC GAS MADE IN USA
Stock is what I am interested in also, unless installing in a 3D airframe that can hold a pipe? Are there any - I thought they were only designed for canister mufflers - maybe much shorter than the pipe?

RE: SYSSA 30CC GAS MADE IN USA
Nice, can't wait to see what a Vess 19A does on the stock muffler. Not sure about longevity at the 9600 + rpms -
|
RE: SYSSA 30CC GAS MADE IN USA
In the lower rpm range, you will get slightly faster spool up with the stock muffler over a pipe....but after about 5500 r's, it is lightning quick.
GSK, you can run an 18x10 or 18x8 in a warbird....that will get you the speed. The higher pitches unload a bit on the more slippery airframes like WWII fighters and other racer types. As the rpm comes up, the power comes up as well. Cant wait to fly the H9 Mustang with the SAP-180HP in it. Should be a really good performer with the 18x10. The only problem is...we have crappy and cold weather right now. |
RE: SYSSA 30CC GAS MADE IN USA

I look forward to the results of the Hanger 9 trial as that what i plan to fit it into . |

RE: SYSSA 30CC GAS MADE IN USA
I just hooked my fish scale up to my Syssa and got about 16.8 pounds of pull on about 8700 rpm with a Vess 18x6. the motor is new and not yet tuned for optimum performance; but a pretty good indicator of why it will hover my 15.4 pound plane.
|
RE: SYSSA 30CC GAS MADE IN USA
You might ask PlaneKrazee how to get 26 lbs thrust with that prop turning only 700 more rpm
|
RE: SYSSA 30CC GAS MADE IN USA
I could do that, the air is not as dry over this way. It might be more like cutting pudding with the prop. I'll not need anything bigger than an 18-6 on mine. :D

Monday looks like a fly day here in East Tenn. I am going to try and burn 1 gal of dino oil @ 40:1 then switch my Syssa to Synthetic. Next time I go out I will try and fish scale mine, not that I really care as she is a bute!!:)

Not sure if i posted these pictures yet or not but here is my plane that i built over the winter and she weighs just shy of 12 pounds by maybe an ounce or two. The engine is running good, and it will pull the plane straight up with no problems.
The adjustment on the carb is a little touchy, I can back the High end needle all the way out and she only looses about 400 RPM. Not a bad thing just different from what I'm use to. I had a slight failure with the center mount that i made in the fuse, and i called Todd up and he is going to make me a new back plate with 4 standoffs. Guys I am going to tell you now that Todd is a great guy to deal with, Thanks for all your help Todd!! |
RE: SYSSA 30CC GAS MADE IN USA
Can someone who has both tell me which has more power, more pull. The syssa 30 , or the DLE 30. I'm about to start a project and am trying to decide on the powerplant. I'm more concerned about stock performance , I have no plan of spending $300 more dollars on a composite pipe and header. also i'm not interested in what it SHOULD do. I really would like to know what it WILL do. Thanks

Was sunny 51F with a light breeze yesterday. No flying video as no one showed up at the field. All white and snowing today. After the wind picked I took some pics. Not as purty an install as others here so I almost didn't post these. Hanger 9 twist 1.50, weighs 9 1/2 lbs.

RE: SYSSA 30CC GAS MADE IN USA
Still a bit too rich on the low speed needle so it loads up a little after idling awhile. No bogging or hesitation on throttle up though. Just drops off the smooth aspect and causes a little vibration when restrained in the startup stand. http://www.youtube.com/watch?v=1yf0RkN_v1k

RE: SYSSA 30CC GAS MADE IN USA
There has never been a side by side for power so no one can honestly answer that question.
Outlaw, What size prop you running ? |
RE: SYSSA 30CC GAS MADE IN USA
I'm running an APC 18x6w. Burp the throttle and it jumps off the ground now.
