RE: SYSSA 30CC GAS MADE IN USA
Texas...I know it gets hot where you are (100 plus)...but even in 93 degrees F with high humidity, 87 is fine...even under severe loading conditions with marginal cooling. I really took great care in designing the hemi combustion chamber, compression ratio, cooling fins, etc to balance power and reliability for long life. We have had zero detonation problems so far. Remember, higher quality fuels are not available everywhere...and I wanted to make sure that our engine will run well with no problems on 87.
93 octance was tested some time ago and we lost 100 rpm off the top.
Todd,

RE: SYSSA 30CC GAS MADE IN USA
This thread is about Todd Syssa's new engine design and it's application to model airplanes
There are a couple of you who insist on trying to argue international marketing strategies, race, economics, politics, quality of other products, and carry this thread away from the original topic and most of these have been removed.
Some of you same people have made some good pertinent posts that were left in place.

A follow-up post to my last one, here are the standard specs on the SIG Sun Dancer 50CC Bipe.
Wing span - 71.5 inches
Wing area - 1668 sq inches
Length - 66 inches
Flying weight 17-18 pounds
wing loading 23 ounces/sq foot.
Engine: 3.2 (50CC) to 4.2 (70CC)
Those are the specs. Knock a pound or two off, or maybe three, and it might change things. Obviously it won't have the B^lls to the walls power of a 50 or 70CC, but it has a ton of wing, so I'm weighing it out this way and that way. If it equals or can exceed the power of a 42CC then it appears it would do a fine job of flying the Sun Dancer around. It would certainly reduce the wing loading, which would in turn reduce the actual requirements due to reduced overall weight.
It sure has me scratching my head and thinking about it..... This might be what I've been looking for.
But just like when I sit around with my flying buddies, I'm interested in other opinions on this combination. Heck, that's half the reason we're in this hobby. Doing it alone would be boring!
Thanks

I am thinking this engine would be a perfect match for the new Aeroworks Cessna 195 that will be coming out. I believe it is designed for the 26~34cc class.

I realize that this post is slightly off topic..but...but...but...I am looking at this plane from a "hmmm...maybe it would be a good fit for Todd's new engine" standpoint. I appreciate your patience with my questions.
Thank you for the info!

This is off topic, but the Cessna was showcased at Toledo this year. I am not sure when the production version will be released. Here is a link to an earlier discussion on it.
Specs are as follows:
Wing span - 90"
Wing area - 1350 sq in.
Fuse length - 69.25" (rudder to cowl)
Weight - 15 - 17 lbs.
Engine - 1.6 - 2.2 glow or 30 - 35cc gas
Price - TBA

This engine won't be enough for the Sundancer. ...... I friend had a DZY48cc twin in one and it did not have unlimited vertical....... When taking off he could go vertical for about 80 feet and then have to level off.
ORIGINAL: TexasSkyPilot
Keep in mind, 3D is NOT my style, standard aerobatics with limited vertical and hammerhead stalls are my type of flying.

I think this strong 30cc would do what he wants, the Sig is very a docile flier.

The ignition is an RCEXL...they are very, very reliable...and work very well...just ask anyone in the know. RCEXL is the ignition to use for singles and twins.

The AW Cessena is alive and well... being tested right now with a Saito, but will be using a Gas 30cc as well.
Another plane that is not out yet that will be good for this wil be the ExtremeFlight 78" Extra when it arrives. It's suppose to be lighter than the Yak which will put it sub 12 pounds.

RE: SYSSA 30CC GAS MADE IN USA
Thank you all for the info on both the AW plane and the Extreme Flight plane. I guess I need to decide whether I want to dabble in all out 3D with the Extra or in trainer/aerobatics with the Cessna.
Either way, these are good problems to work through
Have fun, and thanks again...

RE: SYSSA 30CC GAS MADE IN USA
daveruminski,
I never used anything other than a solid mount...the engine does not vibrate anymore than a glow engine...it actually runs smooth for a single cylinder.
...never had any vibration issues any airplanes it was in...even the stock Funtana, which is pretty lightly built...it is a 10 pound or less plane.
I guess you could use one...maybe it would reduce noise slightly...but I think you should really try without it...
When I originally designed the crankshaft and went by the formulas and present practices, I got it close as possible but redid the forging dies a few times to refine it.
As many know, balancing a single cylinder engine is a balancing act. Its not as simple as some might think.

This engine won't be enough for the Sundancer. I don't think you would be happy. I friend had a DZY48cc twin in one and it did not have unlimited vertical. It was spinning a 20x8 Xoar. When taking off he could go vertical for about 80 feet and then have to level off. When powering a bipe, you just can't look at the all up weight. You have to remember that there is alot of drag to overcome with the extra wing, cabanes, and interplane struts. Looking at the RPM numbers provided for this engine, I would not put it in a bipe weighing over 14 pounds. Keep it in a bipe around 11 to 12 and you'll have a nice hotrod. 13 to 14 would be scale like.

Understand also that I already have a new 3MM TOC 53CC gasser with a canister if the numbers and results on this don't pan out. I'm set either way.

Hi Todd, looking forward to receiving my engine and looking forward to purchasing one of your future twins.
Hi Todd, looking forward to receiving my engine and looking forward to purchasing one of your future twins.
I too have one or possibly two of these beauties coming my way.
I,ve been waiting for them to be released since last August.
What kind of exhaust are you planning on using? I,m seriously thinking about an ES Composites carbon pipe setup.
It should get this puppy breathing really well, possibly even getting the thrust #,s up into the low 20lb range.
The new EF 78" Extra due in a couple of months should be an awesome combo just as Jake pointed out earlier.
This engine put in this airframe with a tuned pipe setup is going to be awesome!

Todd,
I'll take one too. I'd like to talk to you about what kind of muffler you think would be best for the SunDancer Bipe, and if smoke is a possibility. I'm not married to the idea, just thinking about it.
I'll work with whatever timetable you have.
Feel free to PM me for more information whenever you need it.
