I can back up Larry's comments too. I have seen widely different designs, side by side, sailing upwind, and there is virtually no difference in boat speed. There is no design that will "walk away" from the others. If the sails are trimmed "correctly", and being off a turn on the vang, or a few mm on the jib trim, or a few mm on the outhaul, WILL make a difference, the boat will be competitive. Get a start at the favored end, on time, with boat speed. Then hit the first shift, and you will be near the top of the pack!

That being said, I like to build boats! So I will be building my third and maybe fourth too, this winter. I have Brad Gibson's plans for a Reggae, so I may start on it soon.

Mike --- I blame you .

You said a while back I should get out there. I met a guy who was buying one of my boats to race. Invited me to sail at his club which sounded good. Over 20 IOMs racing every Saturday morning plus Solings or allsorts alternate weekends in the afternoon. I had to build myself an IOM and that was the hard part. Now after 2 months I finally have a boat that behaves.
First time out boat hull was porous. Second time had experimental rigging with elastic tensioner. Failure. Now have new servos fitted (bought in WA ) but 10 days to deliver here to Sydney.

I am also just starting my second IOM build. Already have a Hitec drum winch for this boat ($45 or RMG for $260).

Mike --- do you have sheeting details for a Hitec drum winch? Want to mount thru deck in cockpit. Not sure if this can be done with a Hitec drum winch. I have an RMG 380EH mounted thru the deck in my AU Class boat. RMGs have a longer spindle. Also Hitec drum turns ??? with a Spektrum DX5e. Instructions say maybe 4 or 6 . Haven't tested yet as I just started glassing new boat today.

And does anyone have photos of a Maximuss IOM sailing? Yes Trakka that means you . I have the free plans but want more info before building.

Larry,
I will try to take some photos of my hitec winch setup, but mine is mounted infront of the mast.

Mike -- that would be great . Also details of where you mounted your pulley blocks. Pics . Worried about my Spektrum DX5e and Hitec drum having too much travel in lines. Hard to test distance with no boat. Mounting in front of mast would be much easier I suppose.

Hew 565 --- I seem to recall you had some great photos of one of your IOMs sheeting details. Is there a link or repost?

Tanx

Larry.

Telltales

Can anyone give me some advise where telltales are attached to your sails. I have a A and B suit of sails I am rigging. In looking at IOM pictures and regattas, the telltale locations vary from boat to boat. Some boats sailed by the top skippers have no telltales.

Thank youhttp://static.rcgroups.com/forums/images/smilies/smile.gif

The elastic runs like it does so that it never really pulls on the servo arm, but loosens as the arm moves. It could be a solid line if everything was positioned perfectly!
Really, its an adaption of the tension link in a continuous loop as would be used on a drum, but applied to an arm to keep the running rigging tidy in light airs.

I use a Hitec HS7950TH servo and the arm is 3" from center of rotation to center of the block.

A friend's year-long blog about his Vektor build:

http://iombuild.blogspot.com/

He has never built anything, and for a while was banned from using power tools anywhere near a model boat, but he has progressed nicely!

Hew 565,

Yes those are the photos I remember -- thanks .
One point not too clear. The solid line going thru the bulkhead to the stern block. Is that just tied to the end of the sail arm? I'd have thought that line would go through a double block on the end of the arm to a tie off point somewhere on the hull. Can't tell from photo.
Plus -- I count six pulley blocks. At my prices (between $17 and $22 per block) that would cost me more than I spent on the whole boat build .

Cheers
Larry L.

Larry,
Attached is a photo of the set up I have, there are only 2 blocks, even though there are 3 in the photo the 3rd one which is for the jib rope can be replaced with a loop. The winch is mounted sideways just behind the bulkhead.
Hope this helps

Larry, yes there is a double block on the sailarm. The maisheet gos around the block and back to a dead end at the bulkhead near the fairlead.

You could do without some of the pulleys that I run the elastic through, and maybe the block at the shroud for the jib sheet.
