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?
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 😀 😀
Looking good, to what scale are they? only ask as those props would look great on my 1/32 Perkasa torps, did you buy them or are you one of those talented people who make there own, envious as hell me, I couldn't make custard Ha Ha.

HI this was my winter project the hull was given to me by my son who got It at a car boot sale It had been on fire as It was driven by a petrol engine In now has twin brushless motors with 45mm props but going to put 50mm props on when they come as It needs a little bit more speed Built from a set of plans this my first go at this as I build from kits In the past cabins made out of 3mm/1.5m ply and some 1.5mm balsa wood . Hull was sprayed and the deck and cabins brushed with enamel paint.
What ESC's are you using? Battery capacity? Do you know the max current your Thumbrun and ESC's can take? If possible I suggest you use a Wattmeter (a fellow club member may have one) to see what the position Is at the waters edge, this will be a worst case as the model will be stationary and drawing max amps. Brushless motors are power hungry and for max performance work best with LiPo's. Ideally the ESC should have a max rating greater (50%) than the max motor current. Unlike brushed ESC's lowering the throttle setting does not reduce the current flow but does Increase the heat generated. My experience Is brushed motors work best on smaller props. I suggest you check the heat of your setup after a short one circle run when you fit the new props. Look forward to hearing how you fare. Good luck 😀
I have to disagree when you say that brushless motors are power hungry I have one more boat on a brushless and get a longer run than with brush motors a lot of members In our club use brushless with good results
I agree brushless give excellent results and will outperform brushed motors any day, provided they are set up correctly. Power hungry was possibly a poor use of words. My point was that brushless electronics can and do draw very heavy currents which LiPo's are able to supply, and are very light weight. We use brushless on many model at my club and for performance and endurance they can't be beaten. 👍 😀
Just nearly finished my sea queen and had one outing and It did all I wanted. Scale speed and very plesed with It. Standard motor and 12 volt battery. It was last winters project but only just finished. My 1st motor boat as my others are sail.
Looking good. Glad to hear your early sail went well. I am In the process of restoring a Sea Queen and have just about managed to remove all the old coats of paint. As I am using a brushless motor and Lipo battery there Is ample space and I Intend to complete the cockpit detail. I see yours Is quite open, did you resource a particular style? I can't seem to find much In the way of detail, certainly not from the plan.
HI dave I am currently looking to finish the cockpit but the bits that came with the kit were a bit naff. I have put a shelf In and created a door frame to the cabin. I am looking to put steering wheel , morse control and Instruments ,maybe a seat. I will post some more pics when complete.
HI Roger Noticed the door and believe the captain probably stood but not sure If seats were fitted. Maybe I'll look at some full size cruisers for more detail. I have looked at other Sea Queens for Inspiration but this detail Is mainly lacking. I have seen a control type panel on one model placed to the right of the cockpit looking forward but at this scale quite a bit of detail should be shown. I will ask Malcolm Reade of Reade plastics If he has any Ideas as his dad was providing fittings during the Aeorkits period and he may have more details. I will keep you posted 😀
Will be pretty similar In both types as controls are fairly standard. Probably a compass and chart table If sea going. Malcolm Reade Is sending me some fittings so will advise further when received Cheers dave
Yes you right, I built one many moons ago It was my first model boat, cost me something like 30 to 35 shillings (£1.50 to £1.75), from the now long gone Ashton Model Shop back In the late '50s, not radio control, could only afford to run on a 4.5 volt cycle, but my pride and joy all the same. Looks like It had a slight conversion, or hatch Is missing behind pilots seats.
Yes, those models look to be reasonably original. Interestingly, there was only one hatch - the one at the stern. When I complete my long-mothballed Sea Hornet, I'll probably make up a second hatch to cover the engine compartment. How's your progress? Tim.
Yes you'd be right to put a hatch behind first row of seats, that's where motor access hatch was originally, not second row seats as In your model. It original only had two set of bench seats, each behind their own window screens.
Cannot remember what happened to my "Hornet", maybe It went the same way as my CorgI and Dingy toy car, kindly given away by my Mother In my teens, whilst I was In the RAF, thought I finished with them, women they don't understand us fellows :-)
I've just launched my latest model a RAF Fire Launch pictures on this site, still some way to go, fire monitors etc, turned out to be very responsive and quick, once fitted 50amp controller and tweaked blades. Peter47
