If she is the 34" model then she's the Sea Commander, 46" is the Sea Queen. I have got both, picked them up from boot fairs, at least 4+ years ago, and sadly still awaiting refurb. I also have a 46" Crash Tender still waiting the same. As well as a 34" crash Tender I bought back in 1994 as a 50 years anniversary kit and a 46" I got at wings and wheels about 3 years ago both in boxes waiting a full build from new. I have also still got my early 1970's Sea Hornet that also needs a refurb. Amongst other new and second hand models to get sorted out. I always say one day I will get round to it.
Just renovated this one not been used of several years, I need to get back into sailing, was running on a 400 size motor now on a outrunner Mystery D2632-100 and it seems to go very well, will post it on the water later.
How does the coupling work, as it looks to be a flexi coupling. There also looks like you have a wooden support under the motor? With the torque on brushless motors will it not wave about? I look forward to seeing her on the water, hope you do a bit of video of her.
Hi BOATSHED, The wooden block is screwed and araldited ti the keel and supports an Aluminium bracket designed for holding a Brushless motor in an Aeroplane, use what’s available I always say. The coupling is Silicon tube fitted to brass universal coupling fittings and because the way brushless run is very quiet compared to a normal Unversal Joint assembly. Will post it running shortly. Thanks for you interest. Graham
I first started to build this boat with my father when I was about 15 . Then at about 45 I decided to compleat the build. It originally was built to have a Ed diesele engine,but was to costly to run so I changed to electric power. This proved to be the right decision. The boat runs wel, but when I turn on the full power it tends to lean to starboard and cavatat so I have learned not to put on full power. The sea Commander is a pleasure to drive.
😆Hello everyone. I’m a relative novice with 3 projects on the go at the moment. Project 1 is a Riva Aquarama, which stalled at the stringer stage. Project 2 is a smaller Riva Aquarama which stalled at the planking stage. Project 3 is an Aerokits Sea Commander, photos to follow. Kit delivered Tues last week and spent about 4 hours on it so far. Keen to hear of any motor/shaft mods anyone recommends. Thanks

Fast Patrol Launch - Posted: 1 year ago by wunwinglo
This Fast Patrol Launch was originally built by me and my father in'62/3 It was my entry into marine modelling. Initially free-running with a tiny old school blue-cased Mabuchi, it was never 'fast' -as a result it was recomisioned several times over the years but remained dull. In 2013, it was refitted yet again but this time she got a nice potent brushless and a full array of lights. Now she goes very well here at the Oxford lake.
It looks like an Aeronaut Classic, I am half way through building one and am not happy with it as I have built it as per instructions and the bottom skins are a good eight of an in too short. It seems tome that a lot of the parts like the side stringers are way too thin. I saw a picture of one that was being built that some one was doing a couple of years back and now the parts have been dramatically skimped now. I am very dissapointed with the model generally.
Now has name and "port of origin" plus flag and is performing well. Still has a leak and I think the engine tends to run hot. I'm considering changing the original 3-bladed prop for 2-bladed one as I'm told that will cause the engine to draw less power from the battery. Does anyone have any experience with this sort of mod?
I have changed the prop to a 2-bladed one without loss of performance but still had to reduce it's size to stop the motor overheating - to do this I simply ran the motor out of the water and held a file against the rotating prop! - crude but did the job!
Hi Dave, The original prop was about 42mm as was the 2-bladed replacement before I filed it down to approx. 38mm. The battery is a Ni-mh 7.2v 3700mAh 6-cell VP racing battery. As you can see from the photos I am getting a semi-planeing speed which is what I wanted as I think it looks "right" for this model. It is true that the boat is rather heavy but that is because I have left my father's old 1960's transistorised receiver in situ, partly out of sentimentality and partly because it seems to balance the boat nicely.
Hi Ian Looking at the pics it would appear to sit correctly and certainly planes well. If your ballast is forrard it will mean it has to be lifted to plane, at the cost of increased power. If you are still using the Mtronics 600 motor the prop is about right. The specs say 6-12v so running at 7.2 v will probably account for the heating problem. A higher voltage will allow the motor to run at its optimum design speed and cooler. The stall current is 48 amps! I am assuming you have a good a free running prop shaft and tube and the motor and coupling are aligned? Can you post a pic of your prop? Dave
Hi Dave I've attached a photo of the prop as you asked. You can just see where I've shaved it down. This seems to have eased the overheating considerably. You can also see the water inlet for the cooling system that was used with the original diesel engine. This is now piped directly to the outlet on the port side (you can see it working in some of the action photos). The other photo is a fore/aft view of the central bay which contains the motor, ESC and battery.
Hi Ian It's a racing prop and will use lots of power hence the heat. As you have a cabin cruiser it does not need such a coarse pitch prop and changing to a prop with a lesser pitch will improve your running time and produce less heat. Performance will depend on the chosen prop but should not be much different from what you already experience. As you already have a water cooler inlet and outlet you could just wrap some copper tube round the motor and connect with silicon tubing to keep the heat down Dave
This Aerokits "Sea Commander" was built C.1961 by my father with ED Mk4 diesel engine and his own scratch designed and built radio/receiver ( I have all his design documents). He raced it successfully in the early '60s but hadn't used it in years when I inherited it. Have now replaced the IC motor (mothballed carefully) with MFA Torpedo 500 but it runs a bit slowly ("river cruising" scale speed). Looking to obtain semi-planing but not racing speed.
Thanks Johnlikessailing. However, I have now replaced MFA 500 with Mtroniks 600 and got much better performance, although I'm not sure how much of this was due to the change of motor and how much was due to rectifying the slippage due to a loose grub-screw on the connection between the motor drive shaft and the universal joint that I found when I removed it! (Lesson - beware of alternative causes of problems!) Now I just need to sort out a leak - hardly a surprise on a 50 yr old model! Hey-ho!
Kit German port boat. The drive motor 500, LIPO 4000 mA. Hilarious kit from Crick. Combination of ABS and timber. Everything needed for the position of the boat is the content of the kit. Still under construction. Painted hull and superstructure, glazed windows, left mast and lighting.
Bought as a wreck off ebay . stripped down,repaired hull and top sides. re positioned the propshaft. Re painted. New Brushless motor/ Lipos etc. Goes quite well for an old girl, Believed originally built in the 60's. Ill try to upload a video of her strutting her stuff on Wibsey Park lake in Bradford. Edit: I've managed to upload a video of her in action on u tube ,see link below https://www.youtube.com/watch?v=Fn7LxmND-8g
Thats a very nice boat, enjoyed the video, thank you for posting it,Im just getting started with boats and enjoy seeing vids of them in action. Would like to have a go at building one when I have more time, thanks again 😀 😀
Hello, I have just joined the Webb site, and am relative new to boats. I have just finished and got in the water a boat which looks similar to yours, started by my now deceased father in the 70's... But the point of my questions how have you made your hatch's, especially the one on the rear of your boat water tight? mine are not and leak in when out on the pond. Thank you for you time, hope you can help.😊
Hi Ned, Welcome aboard 👍 On my Sea Scout (little brother of the Sea Queen) I used silicon sealant (a la bathroom!) and a small brass screw in each corner. It had to be good cos I had the RX, RX battery and rudder servo tucked in there! My boat was also started by Dad in the sixties. He had it free running with a Taycol Target and wet (very!) 6V lead acid cells. I upgraded to RC and Decaperm motor about 25 years ago and am currently restoring and converting to brushless 😲 Happy boating, Cheers Doug 😎
