RE: SYSSA 30CC GAS MADE IN USA
I do have some of the turbo hose but haven't used any yet. I have been using some 7/8 regular silicon hose and surprisingly it has held up so far in my testing. I'll use it till it blows and hopefully I will be comfortable with a pipe length by then. Thanks to all for the great thread and all the help. It is so good to have everyone share their info!

We're in for a bit of crappy weather so I think I'll install the turbo hose just to get a definitive answer as to whether it will work for us.

Bob,
Regular white from McMaster Carr. It is holding up so far but I'm sure it will blow the 1st round of the 1st contest.
I wonder if some screen over it would help it to hold up. The turbo hose is really heavy and thick.

Going to install the turbo hose anyway, and when I remove the current coupler later this evening I will know what's going on with the spacer and the FG/Teflon tape beneath the silicone hose. And of course I'll be running it thereafer with the turbo hose alone - a much simpler arrangement, if it works.

Bob,
I have to ask this question. Is it worth all the hassel you are going thru in terms of added performance or is it something you are trying to overcome? Guess I'm asking what added RPM you are getting from the pipe?
Good luck with your quest!

For others reading this, a new quite pipe and header assembly as well as the associated parts from MAC's is pretty well going to do away with $300.
So to spend that much extra you need the performance for a reason?

I've discussed the available boost in performance much earlier in this thread. It is quite a boost. I started a different thread in the Pattern Forum where many other details pertaining specifically to piped matters are being discussed.
I'm not sure whether sport fellas understand (or care) why Pattern people would spend
400$+ on an engine and another 250$ on the exhaust system. But we do!!
The ability to turn much more prop is one such reason; Reducing the noise footprint to a whisper is another. This same engine will turn 18 and 19x10 props all day long on the pipe at very useful rpm. It will not do that on muffler

RE: SYSSA 30CC GAS MADE IN USA
I have a handful of flights with this motor on a hangar 9 150 size mustang. First flight dead sticked. I think the fuel line kinked with the added heat of actually flying with the cowl on. I knew it bent pretty sharp before hand anyway. Oh well didn't seem to hurt engine as far as I can tell. I am having trouble getting it to draw enough fuel on choke but I think this is again because of my setup. The mustang doesn't allow the use of the outer normal hole of the choke plate. I will fix it somehow. I didn't realize untill close inspection that the choke plate wont go closed the whole way the way I have it set up.
18X6 zinger pro was not nearly enough prop for my aplication. The motor can handle more prop it seems with ease. Zinger pro 18x10 made a huge difference. With the 18x10 the plane flies just fine and actually winds up having a cool sound on a dive to buzz the runway as it unloads a little more where the 18x6 was turning fast regardless of how you were flying.
To fit a Zinger pro 18x6 with a tru turn spinner was no big deal. To fit a 18x10 was! It's thicker and the crank isn't any extra long so I bored a forstner bit down into the face of the prop a little so that basically the nut went on the crank as far as it did with the 18x6. You only get maybe 2 threads engaging on the jam nut which is needed to accept the spinner bolt, without modifing the prop. I know a top flight 18x12 Needed bored even more than the 18x10 but I don't know that I will run it.
Engine runs great right now, Hopefully I am right about the choking situation and that once it closes off completely it fires up much faster. The rear carb rear exhaust is wonderfull for my setup. Good power, good speed, easy neat installation.

I went ahead and installed the turbo hose. Will fly sometime mid-week and will find out how it works!
Also installed a DB 3" FAI-style spinner, and had to enlarge the slots a lot for the APC prop. Was astonished to discover that a simple Dremel sanding drum works much better than a grinding wheel. Go figure.

Much flying this weekend, another 15 flights or so on the stick. Engine is running great, 102 mph (Radar gun aircraft speed) with the stick and an 18 X 6 video attached..

RE: SYSSA 30CC GAS MADE IN USA
MsgtRob,
Only 102 mph? I guess you need to upgrade to a tuned pipe!
I like the bomb, do you have it set up to mark like a BDU-33? I need to put some on my Sportster.
Glad you and the engine are doing well.
P.S. Looks like you have not had any rain for a while.

Lou,
I think my Giant Super Sportster is heavier than that and it will climb straight up out of sight so you should have no problem with your plane. I am using an 18x6 Zinger right now. Will pick up an 18x8 today, not to get more thrust, don't need it on the "cruiser" airplane, just want to reduce the noise a little.

I don't think you would have any troubles at all. Nice slim profile with plenty of power. [sm=thumbs_up.gif]

No offense, but the math doesn't add up there. 102mph prop speed would be ~18000rpm.

Thanks, good fun. THe airplane itself was radar clocked at 102 mph (Not the prop speed!) The nerf drop is done with a standard servo, piece of carbon rod, some spare hardware and 3 old plastic glow motor mounts (with nose wheel steering) as bushings for a sliding rod. The nerf has an eye hook screwed through a ziptie and a piece of ply. We dropped it about 25 times ad the zip tie/hook never failed. The nerf on the other hand starting to split on the seam, but stopped at the ziptie. MUCH FUN!

Back on topic I'll return to drooling over an incredible piece of engineering and trying to figure out how to justify getting one and an airframe to go with it.

RE: SYSSA 30CC GAS MADE IN USA
What do you mean "Prop Speed"?? I don't think you want to say prop speed per se....prop speed is rpm. Prop tangential speed varies from zero at the hub to well over 400 mph at the tips.
I think you mean air speed that the prop throws back through it's disc area. This will also vary depending on where the plane is (ground or air).
If the plane is at SNL flight for example, air speed through the prop disc is only about 10 mph faster than the plane.

RE: SYSSA 30CC GAS MADE IN USA
No tuned pipe, just the stock muffler. Rpms were in the 7k's with that zinger pro 18x10. Im on the rich side I am pretty sure, trying to break it in the way I always have done airplane engines. I tune my gassers in untill they just barely run right and then leave them there and don't lean them any more. I know the low is rich still thats for sure. That prop flew my mustang very well were the 18x6 just wasnt enough prop for the plane regardless of how easy the engine spooled it up.
