Thanks for the input. The turn fins can be moved up no problem, should they be at an angle equal to the V or vertical, mounting bracket at the hull joint line. The trim tab location OK or is it preferred farther in or out on the transom?

I noticed that the rudder will be inside the rotating prop. Is the bracket too short? where should the rudder be in relation to the prop?

The balance of the parts were ordered yesterday from Steve, along with a pair of Dynogy Packs 3S, 65C, 5000 MAH.

Thanks

Your turn fin angle is correct, look at some of the pic. It is 90* in relationship to the V just as you have them.
The inside distance of your trim tabs should not be shorter than the diameter of your prop.
The leading edge of your rudder should be about where your prop drive dog is. Little bit of either way is ok. mine is just a bit further but if you look from the side, the leading edge is still inside of the prop.

So move trim tabs out and up 3mm from bottom of hull and turn fins up to hull joint line and slightly out on same current angle.
The outside edge of rudder will be inside the prop. sound correct?
Thanks

Yes and yes.
When you said outside edge of rudder, you are refering to the leading edge( front ) or the back (trailing edge) of the rudder? I view mine from the side. How long is your bracket? You have SpeedMaster stinger right? The rudder bracket ( assuming also SpeedMaster) should be 4" version.

By no means wanting to show off, but I got some extremely helpful tips from some great builders and your questions about rudder bracket length and placements of hardware can be found with some from Properchopper.http://forums.offshoreelectrics.com/...gestions/page2

The back of the prop will be behind the trailing edge. The rudder is Speedmaster 21 5.25" inch long, "rudder style" 2.125" setback"
in several pictures it looked like the prop should be to the inside of the leading edge. Am i confused, hope I'm not confusing everyone on this tread.

**tlandauer** · 09-03-2012, 01:07 PM

I am not knowledgeable enough to answer your last question, ( meaning if it really is too short), seems to me it is a bit too short, I ordered the 3/16" Speed Master stinger and with that I ordered the rudder with 4" extended bracke ( set back), the one below the Speed Master21 rudder on the Products page @ OSE.http://www.offshoreelectrics.com/pro...d=ros-spdr-010
The length of the rudder is 6.25", seems long, I know, but people shorten them to where the water pick up holes are, I thought mine was too big, but the SpeedMaster 21 doesn't have the extendsion far enough. I could be wrong though. Hopefully someone else can chime in.
p.s. I re-read your post, now I understand what you are saying, yes, most of the builds I have seen, the bracket is at least long enough so the prop drive dog lines up with the leading edge of the rudder, as i memtioned, it may be a bit longer, also camera angle can give you different pespectives. But at 2.125" inch, I think you would be happier to exchange for a longer one.

Here is a picture of the rudder and stinger.rudder& stinger length.jpg

That is too short as far as my understanding goes, can you exchange it for a longer one? leading edge of rudder should be further than the end of your stinger.

**KartRacer** · 09-03-2012, 07:48 PM

Thanks,
I am sure Steve will exchange it. He is shipping more items to me tomorrow. I'll email him and have him look at the pictures.

Ok some more building today and here are some new pictures. Everything is temporarily bolted in place. No real problems unless of course something looks goofy. Hope not!.
Will post one more picture of the side view showing the rudder in relationship to the stinger. Not sure but it appears that I have the wrong length rudder mount.
Should receive the CF/Kevlar and west epoxy later next week to get started re-enforcing the hull.
Comments and opinions welcomed and encouraged.
BTW any record of how many times a new 1st time builder measures before drilling the first hole:)

Also note the radio picture, the question is : is there any reason not to use this radio and the 5 channel digital receiver with the build?

Sorry last picture, still learning how to post all of this.
This Picture shows the issue with the rudder.
Thanks

Nice build coming along here!! I would suggest to send the whole rudder back and get a twin water pickup model, one for the ESC and one for the motor, that is unless its easier to just by the correct standoff mount. I still prefer the seperate cooling for each though. The big Speedmaster rudder would be nice.

This one is made with six different setbacks, you probably need the 4"............. http://www.offshoreelectrics.com/pro...s-rud-dual-tap

Have you considered a 4092 for 6s?? The 1480kv would be sweet! http://www.offshoreelectrics.com/pro...o-4092&cat=148

**lenny** · 09-03-2012, 09:52 PM

Yep,

That is going to be a nice boat for first one,
This would be a good motor and should get it up on plane real fast. http://forums.offshoreelectrics.com/...or-with-jacket

**KartRacer** · 09-03-2012, 09:52 PM

I sent Steven an email on the rudder and can certainly send it back for a better selection. Steven is out of the 1600kv motors and I was afraid that the 4092 on 6 s was pushing the ESC and or Batteries.
Steve maybe you can chime in here before you ship tomorrow?
