I had the same problem with the oliptical holes in the Aka so I finished up doing the following: viewtopic.php?f=75&t=13167&hilit=crossbar Best mod I have done to date. It was like replacing the shocks on your car. I didn't realise how much noise and vibration the AI had until the insert were put in. Hope it's of some help. |

I had a look at the various mods on the joints a while back. I am going with the bronze inserts as it should be (hopefully) a long term fix and I enjoy doing modifications. It seems to me packing out the joint with a spacer, will sort the problem short term, but if it has enough tension in it to stop the arms moving about on the pin, the pin will probably start to oval against the spacer. I am in the lucky position where I have complete workshop facilities (my 4x4 business) at my disposal which allows me to indulge myself with these sorts of projects. It is probably over the top, but should be very satisfying when completed. I am also making up an alternative rudder handle. I am going to make a slightly longer, taller one and will fit a pintle on top, (as used for the strut on the akas and the spring loaded socket), together with a carbon fibre tiller extension offcut that I have kicking about to make a tiller extension for when I sort out my 1/2 tramps. Alternatively, I am also considering using a couple of aka struts with a joiner in the middle to make it long enough.That would then give me spare parts if I have a breakage. Still thinking about this. I have noticed that the current hole in the plastic for the rudder handle pintle looks to be distorting and twisting in the plastic, so am considering making a stronger plate with a bush for the handle / spindle. If it is not too much hassle, I may also incorporate some sort of detent system that will allow me to lock the rudder off in various positions to hold a course. I have been checking out some of the Moth sails . I am wondering whether one of those with a boom to give it a good shape would be worth a go? We have several foilers at the club and they are constantly upgrading as each new design comes along, I could probably pick up an old rig for a try out for not too much dosh. Now it is cold and wet here, I am in no rush to get this finished, so can indulge myself over the winter. |

I bought mine in February and we have just been through winter down here where all the AI's were in garages being modified. The weather is now spot on so it's time to test out all the winter mods. I also thought about the bush idea for the connection which I must admit would be a better option but quick, simple, resourses available etc I had to go the pov version. I do think though that the pin should be sacrificial or the connection have removable bushes. There is talk about a different design for the next model so we will have to wait and see. |
