600nm at 477 rpm, ~40 hp. But it weighs 660 kg. When I build engines, I concentrate on power, and not much on vibration. This seems to be the other way around. This has so little vibration I could probably sleep on top of it at full throttle if I wanted to

Also, your RPM gauge is the weirdest thing I've seen by far . Try using a more circular shape, and it will be easier to understand!

Hehe, this sure is powerful then! And I made the tachometer based off of those early 80's square tachos, and it is accurate on the 4 and 8, sence those mean 40Rad/s and 80Rad/s. And yeah it takes alot of practice to get little vibration! Thanks xD

I don't wanna sound harsh, but how exactly do you build your engines? I mean, I am the suck at collide tech, but my collide engines usually get between 0.4-0.7 hp / kg, but this is about 0.06, and you've been building collide engines longer than I've been building engines period. Not saying that to say I am better, but maybe I could help you out!

It's near impossible to explain without a video tutorial but, no offence but I don't really need any help on these.. I like to learn this stuff mainly on my own but, thanks for the offer
