    hi there Colin,

    just to put another spanner in the works - when I built an MTB, I made a Carley raft and in the interior of the floating chambers I wound a coil of aerial wire for the receiver - this sits on the deck. I know it goes against all rules for radio control - but - this model has a pretty good range - The length of the lake - how long the lake is I cant remember. However I know anything now more than 100 yards away it goes to a blurr. The other model is HMS Ajax and what I did there I measured the length of the aerial - cut it so that from the receiver to the deck was about 3 inches. The rest of the aerial is made up of brass railing around the side of the boat to the equivalent length of the original aerial.

    This again works well so my theory is, if its worth anything, we are not flying aeroplanes where they are hundreds of yards away - the majority of the time, we sail models pretty close to ourselves.

    John

    Hi, my experience is that assuming you wish to keep your model boat in visual sight then the aerial length is not critical.

    Make sure there is some of the wire going along the length of the boat and that here is at least 6 inches of vertical aerial. I often have a fixed vertical scale aerial with a trailing wire and socket and plug the end of the aerial into it.

    This means I can remove the superstructure and just unplug the aerial.

    Sorry this is not a technical answer but I have a background of electronics and up to 200 or 300 feet range it is not a problem.

    I have seen many model boats where the aerial has never been undone from new, they seem to work!

    Let us not find extra things to worry about! We have enough on our collective plates already!

    Best regards

    Roy

    "That's why I still have and maintain my old Graupner MC-10 40Meg set for my subs.
    Never seen a 75Meg set, they ain't allowed over here.
    Thought they were for hairyplanes with you guys?
    Maybe they changed the frequency allocations when 2.4 Gigs came in."
    Nope, 75 has always been a surface or sub surface as the case may be, freq over here. 72 is aircraft only. I love my Robbe F-14 just for that reason. We may be cousins, but we are definitely different, in case no one has noticed yet.....😁

    "the wire length is 61.0 cm. From the case."
    Sounds good to me Colin πŸ‘
    Same as my little Nano RX.
    Should work a treat, does for me in my U25.
    My eyes fail before the control does πŸ€“
    Look forward to your Sea trial report Admiral.
