Take a few pictures of the rest of the boat, will ya? :) | | | There are 101 different types of people: those who understand binary, those who don't, and those who just can't count... | |

only one way to find out
I've used that arrangement myself for several ships & it works just fine. A couple of comments: - Reverse the orientation of the servo & you won't have as long a loop of chain. That will help keep your tension consistent & less likely to slip off (like when somebody shoots it). - You're going to have serious over-throw of the rudder, with such a small sprocket on the rudder vs. what's on the servo. I can't count teeth 100% reliably from the photo, but it looks like about 18 teeth on the servo & 9 on the rudder (2:1)? Assuming that the servo turns about 90 degrees, that means your rudder will turn 180, which is way too much. For some perspective, 1:1 scale ships' rudders only turn about 30 degrees hard-over. Any more than that & it quits acting like a rudder & starts acting like a brake. JM | | | |

| | 07 Apr 2007 09:17 PM | | I can’t turn it around do to the wire and i do have a 9 sprocket couldn’t figure the right ratio so I should use the 1:1 instead of the 2:1 that is the $100 question the check is in the mail thank you. | | IRCWCC Fast Guns New England Task Force, http://netfrc.com USS Massachusetts BB 59 South Dakota Class Battleship Awards

| | 08 Apr 2007 04:22 PM | | Here is the rudder assembly for the NJ: Seems like we are all making similar decisions. (Funny how well the camera captures all the scratches!) I actually used a belt & the (large) pulley from a traxxas & the two smaller pulley from a HPI Super Nitro. The traxxas pulley fit perfectly over one of those round servo arms, which you can see in the photo. So I glued them together & perfect! The whole thing took about 2 days. The material is stainless steel, which I have tested not to rust. Most stainless steel should not rust; but I have submersed it now for 2 weeks solid... Other than getting quite dirty (The water's quite yucky), it is not rusting. YEAH! I plan on continuing the test for several more months just to be sure.  | | Cheers,
jks
