My bad. 180 degree opposite.

I like the idea of AAC - uniform materials expansion and all that.
Apparently the aircraft boys swear by it.
My AAC Sirio look very promising, about 3 litre fuel through it, it still feel tight on TDC when it cold and hot.

Like I mentioned earlier, you need to cut an extra slot / groove for the STS piston sleeve to fit onto a Nova based crankcase.

I believe the Sirio sleeve will have different timings as the rod length on the Sirio is slightly longer than a Nova based engine.
The slot that keys in with the pin in the case is 180 degrees off. This can be fixed with 5 minutes of measuring and 5 seconds of dremel work(cutoff wheel)

Yeah, we had a night meeting last night - got home and I wasn't tired.
Since it is Fathers Day today, I figured I could get away with it.

Errrm . . . I thought the "top_gun" was the "777" and that it was a moded 3-port Sirio?

I'm confused, now.

Yes Top_gun is 777. He has mod the 3port also true, but it because today is a outlaw type of race that's why we use 5 port. Top_gun moded 5 port is used by kitracer today.

The Novas engine piston size is 13.76 mm and Sirio is 14.00 mm. It wont fit, it is totaly different engines.

As I sad before I can speed up and have them available in two weeks, but it will costs some xtra and I don;'t see any reason to go for it, unless somebody badly need it. The scheduled time is mid of November.

today only this one:

STS RS3
ok, this is for those who can't tell between old and new STS engines (or whoever cares :-) ha ha )

The one on ebay (above link) is the "OLD VERSION".

One easy way to tell is :

crankcase old : black (dark), new : gun metal (light)
rubber piece on slide carb old : blue, new : black

OS?.....Team ORION?...Team Fantom?.....the new STS motors?....

lets hear it....
I would sugest to say Sirio and after that OS. Actualy OS is pretty smart engine from my point of view and I am sure there is some potential.
Hey Harri do you want to run OS done by me in Las Vegas?
What size are running-.12; .15 or .21? rear exhaust or side exhaust? What chasis?
