Someone has kindly given me some RC gear for my first boat.  A hitec Ranger11 transmitter 27MHz,  4 x receivers, a bag of assorted crystals and 6 x servos. I realize that 27 MHz is a bit old fashioned but it should do me for now. So I have two questions, there are two types of receivers, 2 x Super narrow band HAS-2MB and 2 x HP-2RNB, which one is the better receiver or what is the difference.  There is about one meter of antenna wire on these receivers, can it be wound round and round the opening where the batteries are or does it have to go up into the superstructure

I can't tell you which receiver is best, but I will say that whenever possible I leave the aerial inside a scale model. I usually stick it around the inside of the hull just under the deck using bluetack.

Same here, keep the antenna inside. I know that technically it should be vertical, but do you know of anyone who holds their TX bolt upright? The lab figures in some of the technical papers would suggest that 90 degree cross polarisation would result in a huge loss of signal, but in practice, the loss doesn't seem that great, especially at the reasonable distances most of us need to operate at.

27Mhz is 'traditional' not 'old fashioned'  but does seem to suffer from interference more than 40 but with most other people on 40 (at least in my club) you can have the band to yourself at the pond 

I don't know which RX is the better one so I suggest you do some range checking on dry land and see which you think is best.

Just a guess, but the "super narrow band" may be less prone to interference.  Of course, it might just have been a sales ploy label.

Thanks for the help lads, done a range check with both receivers and there does not seem to be any difference, so I am going to use the super narrow band one, as malcolmfrary suggests there could be less interference with this one.
