I just have a quick question about running dual engine hydros ( or small riggers) are the props turning the same direction? if not how do I get counter roatation? Thanks

Twins use counterrotating props. Never had one (and never will - cant afford 'em!)

You will have to modify one engine to run reverce rotation , what engines do you have ? Is this a rigger hull?

Yes a small rigger, I have seen this setup on a couple of rides but never up close , I didn't know if they share a central line, or if they each had there own prop!!

The riggers I have seen at the races running twin macs or cmbs turned the same way each with its own prop, and wicked fast too !!!!
