A breakthrough in piston engines (at least for me). Now a factor or 2 and 3 piston speeds can be accomplished with resulting water speeds of over 50 mph and in some cases 70 mph +.
See load-testing link:
The break through is in both that the standard rotator seems to have a max rpm, and vibration becomes a factor at high speeds.
Evidence suggests that each rotator will rotate or x rpm on piston speed set to 1. Anything above piston speed of one results in massive failure. So by adding a second rotator for any part that moves past 360 degrees seems to overcome this barrier. However, vibration then becomes another challenge to overcome.
Bench speeds of times 2 and 3 have been achieved already and for real world application, they are down rated by 20%.
Feel free to use, modify, further develop.

I'll take em all
Via a universal joint...@Starbound
How do you transfer the power through a bent shaft like that?
@SpiritusRaptor I'll get around to you later in the day, thanks.
Happy to have a look at it. The oscillation is a pain and there are a couple of things to check. Speed, exact lengths/radius and that its mounted on springs.

Hey SR, it's been awhile.
I have a project coming up that requires me to develop something like this, although I want to make something that fits in a very small space (smaller than the smallest engine here!). After repeated experiments, the major issue seems to be that the pistons won't rotate the shaft in a single direction, but instead in an oscillating back-and-forth motion. Mind if you can guide me on how you fixed that issue here?
@SpiritusRaptor
Here it is https://www.simpleplanes.com/a/uYD9g4/Marine-development
Later today when im on wifi@SpiritusRaptor
Are you able to upload what you and I’ll have a look.
@Genterprizes
Hey guys, im trying to apply one of the two stagers, but i cant counteract the torque, please help
Welcome
@Genterprizes
Thank you these even work on mobile
I've got three on the go, another marine/sub sea one, and aerial one and some other messing around kinda things
@LancasterAce
@AerialFighterSnakes I do have an inverted V4 for aircraft use
This rivals the work of Leonardo. You are a true genius.
Oh ok. That makes sense lol. XD@SpiritusRaptor
They are not for aircraft, they are for submarines in fact. Using 2 engine deals with the rotational torque.
@AerialFighterSnakes
They don’t work. I tried to make a plane out of one of the engines but it wouldn’t go forward. It just span around because of the torque. Even when I balanced out the torque, it still wouldn’t move. Can someone please tell me what I’m doing wrong?
cool!
Very noice. You should make a piston powered plane with these kinds of engines.
Ah dope thx @SpiritusRaptor
feel free to use
@Kitten777
Very inventive!
Hey do you mind if use some of those props to see if I can Improve my magnet turbine?
YAY!!
