Best way to stabilize washers in Infernal Robotics?

[Mmmmyum]

I've been trying to build a helicopter with Infernal Robotics, but the helicopter blades start jittering around before the entire thing that's doing a magical dance. It's more an autogyro with propelled blades.

It goes straight up alright, but once I try and move it spins apart

Wow! I tried making that same exact design some time ago, but was not successful. I think the problem lies in slinging around the engines, moving all that mass, with the thrust vectors changing drastically. Ultimately, I could never get the blades to spin fast enough, and the very small amount of lift I did get, was due to the engines being angled toward the ground. If you don't mind a shameless plug, I made a functioning helicopter using the powered washers instead.
