      Hi guys, I’ve just got the bug for Rc model boats. My late father really got the bug for the hobby and with me already racing 1/10 cars and building plastic kits, I thought I’d I’d make the move to water myself and male the most of his boats and equipment. I’ve started an aeronaut diva kit, and I have a couple of “work in progress” models I bought off a popular auction website.. So.. Coming from cars to boats, feels a little intimidating.. Propeller sizes, motor sizes, rudder size, which esc, how quick/slow will a certain setup be (I’m going for just over scale speed).. I guess what im Asking for is help/advice with everything! I have the kit to build which I am enjoying very much, but working full time, It’ll take a while to get finished. I have a graupner sea commander, without any electrics which I plan to go to town on the finish.. I could really do with knowing what a good setup is going to be for it.. My dad’s MTB and Tug are ready to go and the yacht is all rigged up, but I have his Hms Coventry which, while it is mostly complete, it still needs an esc or two?? Umm, if you guys could help me out with these small issues, I’d be very grateful.

          One thing at a time, m'duck. Your note reads like a stream of consciousness. Concentrate on one of the models and let's take it from there.

            I guess you’re right there, but I’m just throwing out what I’m planning ahead. But I think first “port of call” would be the frigate. It’s a twin prop and has been a runner. My dad bought it from his friend last year, but acquired it without any electrics. Am I ok to assume I can use any of my car transmitters and recievers for boats?

              Yes, Stewart,

              surface R/C frequencies for boats, so you're OK. Many boat people use car ESCs too. I think it's just a case of getting the Amps right, but I don't use em, so ask here. The gent above knows his electronic onions and is worth listening to in my experience. Picking one and getting that right is very good advice until you have the confidence to have half a dozen on the go at once…like me <G>

                Thanks Martin, fancy seeing you here! I’ve got a few brushless and brushed setups for cars, so I could try one of those out in the diva. I don’t really understand how a twin motor setup works though.. My dad’s has two escs and brushless motors. Can I use one esc? Or should I splash out on a powerful setup for the frigate? It might just be easier if you guys could tell me how you would set the boats up and I could start looking for equipment from there?

                    (Samuel Beckett, actually. I was afraid of Virginia Woolf……..)

                    We will need more infomation on the size of the frigate, and please don't just say "it's 1/96 scale" or whatever. As I've pointed out to several customers, it means nothing to a non-warship person like me. A 1/96 Titanic would barely fit in my workshop whereas a 1/96 coracle would fit happily in an egg cup. Its length and beam would greatly help, together with the size/no of blades of any propellers already fitted.

                    And no – you can't run two brushless motors from one ESC. If you want more information on twins then have a read of this article **LINK**

                        Thanks for the link Dave, exactly the information I’m looking for. The boat is 51″ in length and beam is 9″.

                          And after looking closely, it appears it has one esc fitted but with two motors? There’s a service in there too. I’ve got a couple of jobs to do about the house, but I think if I connect a receiver to it and battery, it may be good to go..

                            Ok, I plugged my car reciever in to the boat, set it up and everything works. The props counter rotate too. It’s been in the bath (only just fits) and seems to be working very well. One question have though guys, what type of oil/grease should I put down the tubes to the props? I have white grease, should I syringe that down each one? Sorry for the million questions, I was getting ahead of myself and I thought my dad had bought this as a project shell, not realising it was pretty much ready to go!..

                              Stewart, Oh dear, you are asking the question that we all agree to disagree on.

                              .​Personally I would say a drop of oil on each bearing before sailing is enough, water will get in and lube the bottom bearing and likely the top bearing, if not then the drop of oil is enough: Others have a tube fixed to the prop-tube by which they can fill the tube up with oil, causing emulsification and massive pond pollution, others swear by grease.

                              Take your pick. THERE IS NO RIGHT ANSWER!

                                Thanks Ashley, I certainly don’t want to add pollutants, but a drop of oil might be the way. Would a 3in1 type oil suffice? My main concern was wearing parts or damaging anything through not being lubed.

                                  Surely the answer would to use a sealed shaft you wouldn't whittle your own prop would you a little expense but surly worth it ..mark

                                    Sounds like a plan to me, I’ll check them out. I’ve got a lot to learn about boats

                                      Check out " cornwellmodelboats.co.uk" good selection of shafts also westborne models do proper sealed jobs and they will prolong the life of your motor so a small investment now will save you money ..mark

                                        ….but check the spellings first. Search engines are particular about things like that.

                                        There are those who would advocate not ordering goods from the latter website because of their poor recent history. I couldn't possibly comment.

                                        I buy my shafts from Model Boat Bits and don't bother stuffing them with anything, but I do lubricate the bearings with light machine oil before every sailing session. You will get a thousand different suggestions about this subject.

                                        Suit yourself.
