Seaducer Question

[Sean Bowf]

Dull prop would cause that kind of prop walk...but again, I had the EXACT problem you are having, on my .45 mono...and swapping the rudder servo fixed it. The faster the boat went the more it pulled right. So the more "in tune" I got the boat, the worse the problem was. Swapped out the servo and it fixed it. The servo I put in is a little weaker than the one you have, but it is only a .45. Also, I weak battery pack will cause a servo to not have the power it should. If your battery pack is old, this might be the problem.

Someone earlier said to move your rudder control rod end all the way in on the servo arm. Did you try this? Takes less torque from the servo to do what it needs to do when the control rod end is moved in... If it is all the way out now, and you push it all the way in, no cost...and if the problem goes away, or gets better, you know it was a weak servo, and it cost you nothing to find out.

If you have a lot of prop walk, and the rudder is too small (too narrow, or too short), that might also cause your problem.

I have a .67 Seaducer set up per instructions. All Seaducer hardware with offset Strut. Rudder depth and placement per instructions. Boat runs strong and turns nice. However I need to hold a lot of left rudder in the straights to make it track straight. Is this normal? Any ideas of what to do to correct this?

Robert also consider the slop in the radio box mounting hole. I shim (G10) or wood will work) the Radio box to fit very snug into the square. A sloppy fitting radio box will allow the boat not to track straight too.... Just another thing to check.... P.S I have replaced many MG645 servo`s in seaducer 60 boats. Not the best servo choice for that paticular boat. I may run them for throttle But not for a turn servo. Also make sure the strut dept it correct to seaducer specs. A extremely wet Hull will plow to the right. can you send a pic of the transom hardware from the rear of the boat. I have built many of the 42 seaducer that work perfectly & run 64-65 mph all day long. the inst sheets that are provided with the boat will get you extremely close to a great running boat.

JR DS8711 403 oz-in It's a little pricey but have submerged more times than I can count. It is rock solid,water proof and heat sink alu case.

Re centers and holds strait. My Cal craft runs like it,s on rails with it.

This is one place you need to get the best. Have a box full of junk servos This is the only one that did not end up in the box.

Robert,

Take a look at my strut setup on my .67 Seaducer if you make it up to my place. My prop shaft and strut are offset slightly on the transom and the strut is at a slight angle with the prop turned to the left slightly when looking at the back of the boat. It wants to steer to the right slightly during mill time but when at full speed it steers straighter. This is with my steering trim set at the center point on my transmitter.
