    Vintage IOM

    I know very little about this model as I bought it as a lockdown project in pieces. The hull is fibreglass the deck, keel and rudder wood and the ballast is lead. The A rig has Hood logos on with a 12.6mm alloy mast. The original Sail Winch was a Futaba S9401 modified by Tony Abel Yachts & Winches with a multi turn potentiometer to make it into a drum winch. While this worked it never returned back to the same position so was replaced with a Hi-Tec 725BB. The rudder Servo is a Futaba FPS148. Sorry the picture is upside down but try as I may it will not go back up the other way! I have remade all the through deck fittings and added a fairlead to the mainsheet to stop it tangling. One shroud bottle screw was unserviceable so a new one was made. The shrouds have been replaced with ones that are the same length! The mast was a bit of a mystery as the shroud holes were not in line with the gooseneck! The mast had been sleeved (badly) at some point in time and possibly reassembled incorrectly at which point the perpetrator may have given up on the whole project! The ballast was about to fall off so that has been bolted back on. The radio tub fell apart in my hands so that is new. It sails very well in light airs and was only half a lap behind the fleet at 3RRYC in Rickmansworth where it can be viewed/tried using my radio which is not included. Unregistered and unmeasured. I have my eye on another project so this one can go. £120 Cheers, Trevor
  2. Have you tried e-Magnets UK | Online Magnet Manufacturer and Supplier (e-magnetsuk.com) ?
  3. I don't quite follow what you are saying. The ESC must be plugged into the Throttle slot on the RX or it wont receive a signal. Nothing is plugged into the RX battery slot unless you have a separate battery for the TX in which case the Red lead from the ESC must be disconnected. This is from the Spektrum manual.
  4. Either you have something plugged into the Receiver wrong or the Transmitter is set up wrong. Has this setup ever worked? Is it all new to you? Perhaps you could pull all the servos out of the RX and plug the throttle servo/ESC into each position until it works. The TX can do some clever stuff with channel mapping so you may need to do a reset and start from scratch. If you don't have them the manuals are available to download. Cheers Trevor

    Sheeting Out System

    Oh well it was a good idea while it lasted. My ISIS goes from 10th in the fleet to 3rd in light airs so I can’t complain! Now perhaps if I oil the gooseneck .......

    Sheeting Out System

    Following a very light air day it occurred to me that a system to fully sheet out the main sail would be jolly useful but I wonder if the rules allow such a thing. Rule C.5.4 (c) States:- Except where achieved by mechanical systems, automated control of rig and/or sails and automated steering and/or navigation are prohibited. Would a shock cord system that kept the main sheet under tension be allowed I wonder? Cheers Trevor
  7. Thanks for that. I found a you tube vid with a step through. I had been in the right place but hadn't changed the values by enough to make the servo move! I am building an RC yacht rescue boat that needs three channels for the "jet drive", two for the electric ducted fan (backup propulsion and artificial wind) and the sixth for the hand that grabs the shroud! Cheers Trevor
  8. When I plug the servo into AUX (Channel 6) on the RX it moves a little so I know it is active but I can't figure out how to control it from the TX! Nothing in the manual that I can see. Cheers Trevor
  9. Hi Darin. That's where it is at the moment so the long aerial can go down the aerial tube that's just under the deck.
  10. Hi FRA Not sure the drain hole is a good idea, at least not on mine as the pot is only just off the keel! I did contemplate not having a pot, velcroing the (sealed) battery to the keel (makes it adjustable ballast) and mounting the RX (waterproof anyway) on top. Cheers Trevor
  11. Hi Crashard Yes the DX6i does have a comprehensive throttle curve function but only if you are using the Helicopter programs! One of the first programming steps is to choose which Model Type, ACRO or HELI. That does beg the question as to whether Helicopter mode will work for sailing. If I get desperate for more subtle control I might try that! Cheers Trevor
  12. OK now I've got Exponential set up on the Rudder and I've also discovered the dual rate/expo switch so I have 30% set on position 0 and 60% on 1 so I can experiment. Sadly the sheets are on the Throttle channel which has no exponential facility!
  13. Thanks Ian Yes that makes sense. Thinking in aircraft logic Ailerons might want to move the same up as down as they work in opposite directions but Elevators might want to go down less than up. I can see why the default is 100%. If you needed to go more than 125% you perhaps need a different servo arm? I had thought of using the exponential feature on the rudder so might experiment with both later on. Cheers Trevor
  14. I am familiar with radio control from having built and used analog systems but now I'm puzzled. I've recently acquired a DX6i and while the sizeable manual is full of stuff it is not at all clear on some topics. I am slowly getting to grips with this digital system but still don't get why some channels can be adjusted from 0% to 125% but have a default setting of 100%. Is this to do with their use on aircraft? Has anyone written a book that explains more about RC and in particular the Spektrum as applied to sailing? Cheers Trevor
  15. Hi. I'm new to RC sailing and I've recently acquired an ISIS dating from about 2006 and wondered if there was any documentation on setup or any drawings with dimensions etc. I am getting lots of advice from club members but some of it is contradictory or not logical. Cheers Trevor
  16. Thanks Eric that's the name I couldn't remember! Cheers Trevor
  17. Saw some very nice cradles in use this morning but can't remember where any of them came from! Would rather spend my time sailing rather than making one but have so far drawn a blank finding a supplier. Any suggestions? Cheers Trevor
  18. My idea of cable entry from the bottom was a non starter as the pot rests on the keel! A 9mm strain relief grommet will just take a lubricated servo plug. With the neck inside the pot I could just squeeze the assembly with three cables, through the deck recess. The grommet neck is filled with blu tak. Pot sealed to deck with silicone without sanding as it will have to come out if I need to change a servo. May put a screw in if it turns too much although the aerial tube is glassed into the hull and protrudes into the pot so may act as a key. Can't see it leaking much even if the silicone doesn't stick. Cheers Trevor
  19. Thanks for that Frayz. Part of my problem was that the holes had blu tac but it was so dried up that most of it had fallen out!
  20. I'm replacing my pot as it has gone brittle. The one that came out had a number of holes in the sides for the various leads but I'm thinking one in the bottom with grommet and sealant would be better. Slightly off centre to allow for the battery to rest on the bottom. There will be one small hole near the top as that's where the aerial tube is glassed in. Is this the right way to do it or do you have any better ideas. Cheers Trevor
  21. So far so good. Due to the difficulty of accessing the top of the tube under the deck I made a small collar to stop the tube pulling through the deck and added epoxy during assembly. Having drilled the bottom the bottom of the tube I put a long pin through that was then glassed to the keel area in the same way other fittings are fixed. Don't think that's coming out anytime soon! Thanks for your help. Cheers Trevor
  22. Richard Sailsetc headsail swivel tube product code TUBEJ under Hull Parts shows the parts and the description that you gave earlier and useful pictures. All ready to go now! Just need to take the plunge with the glue. Cheers Trevor
  23. Richard I see those last few boats have the same system. On closer inspection of my tube I find a ball with a hole located by three dimples a half inch from the bottom. The line was knotted below the ball. I'm wondering if I should install pin instead and loop the line back up to deck level to provide adjustability? Cheers Trevor
  24. Thanks Richard. I will have a go at that in the morning. It seems as though it has been done before as I have a bit of cleaning up to do first! I have looked through a lot of Sailsetc documents but can't find the bit about the line in the tube. Cheers Trevor
  25. I'm a complete beginner to this hobby and on my recently acquired ISIS the tube that takes the headsail boom pivot has pulled out of the hull! Before I glue it back in are there any recommendations as to the best way to set this up? Also any links to web pages regarding the fittings and adjustments of an ISIS would be gratefully received as although my fellow club members are exceedingly knowledgeable and helpful I don't want to be a pain. Cheers Trevor
