Ouch! Sounds a bit expensive.On the advice of Dave M on this forum I bought myself a wattmeter and it certainly takes the guesswork out. I went through three esc's on my Lesro Sportsman before I got it right- hopefully! Also spent a good deal of time anxiously waiting for my Rapier to drift back to shore after it popped a fuse- twice. Now I know what the limits are and I just didn't have a big enough fuse in.
I'm having just what you describe with batteries being too far astern- I'm going out Monday to try them in the middle of the boat. Also hoping to get some LiPos when I have decided on a make.
Hope the new motors and fans work out and that you get some good shots on the water eventually.
All the best...Ian - sharpy1071Chief Petty Officer 2nd ClassHI Ian, well the original motors came from a discount store, £2.00 each from memory, they work Ok in my USS Crokett, but I have no glazing and the hot air can escape! I think the sequence went like got hot, melted fan, fan fell off, jammed Motor, fuse blew. I couldn't get any water cooling pre bent from Westbourne so will make my own tomorrow. I have opened up the funnel a bit more on the side and place louvres over the hole, I will get a photo. I did use LIPOs (turnigy 3cell 3500) but now have gone over to A123's much better I have 3 in series X 3 in parellel Giving 6600 MAmps @ 10.4volts.These are very safe batteries, almost unbreakable, I use them in my planes they weigh a little more than LIPOs but a lot less than Gel cells about a quarter and can be forces charged but you would have to sail all day to flatten them. Thanks for your interest, speak to you soon, Brian

1/12 scale 33" and 54" long.
Vic Smeed plan Thornycroft took about 20yrs (on and off) to complete and has an Electronize 43HX 24v 15A controller, 2x 400 sized 6-12v brushed motors 4cell 3000MAh LiPo for main power with seperate 3 cell LiPo running a computer fan for cooling (fan is linear and sucks air through the boat from the front hatches and blows it out through the rear hatches) There are also seperate 3 and 4 cell AA NmH packs for nav and interior lighting.
Boat runs 28mm 3 blade props and runs at a realistic scale speed and attitude. Radio gear is 2.4 and I have modified one TX for twin throttles and at present am running both these boats simultaniously on the one TX.
Have bought twin car ESCs, batts, RXs and BECs for the PT and the (36") British Power Boat 64ft HSL I am building (modelled on the RNZAFs 64ft HSL- the only one sold in the southern hemisphere - in 1940) Went on board as a teenager before she was ruined by being turned into a pleasure launch so it was a help with the building. Still remember the wonderful alloy 'Power Boat' stair treads down to the ward room. Will get some pics up of the HSL as well.
- redoctoberAble SeamanHI Dave,

`Ray - circle43nauticalChief Petty Officer 2nd ClassBRAVO ZULU! I LOVE DOUBLE-ENDERS. THIS IS MY USCG 52' TYPE F WOODEN MOTOR LIFEBOAT (POSTED)
BEAUTIFUL WORK, SIR.
- circle43nauticalChief Petty Officer 2nd ClassBRAVO ZULU SIR! I CAN RELATE, AS I GOT THIS BILLING BOATS USCG 44' MLB KIT IN 1989 BEFORE MY DAUGHTER, AND AFTER A LONG FORCED
HIATUS, RESUMED BUILDING IN 2015. I'M OVERHAULING, BASICALLY, NEW PAINT & ELECTRONICS. MY PERPETUAL WORK IN PROGRESS, LIKE MY KID I RECKON.
- balooRecruitThe numbers are obviously wrong on the model,they would be either 52 or 54.52 or 54 is the size eg: 52' or 54' and the last two digits are the station number,so if you choose one all the info will be in the lifeboat book you are getting from amazon,also if you need flags for your model,my friend does them,each one he does are painted free hand on silk not printed
- Dave MVice AdmiralHI baloo
Yes this was a picture as received. I did start to build and there is a build blog on this site. I ran into problems with the hull painting and put the model aside to finish later.
I did several mods to the deck and superstructure to make the detail correct and at some time I will restart restoration. I will use the correct numbers once I settle on the particular boat I will model.
Thanks for your interest and suggestion

- brnbromRecruitLove the rough water shot! its given me some inspiration to finish my own 3/4's built Aerokits Solent given to me by my plumber !
I have fitted 2 decaperms and Bobs Boards and have all the bits to complete it apart from railings.Do Speedline still stock railings?
Could also do with some detail pics as I have only got the original plan. - froggyt996Petty Officer 1st ClassHi
Yes you can still get the pewter handrailings from Speedline. if you PM me I'll send some more photo's to you.

It was built as a fun boat so I could sail with my friend Peter thomas with his variuos boats.
Several things have now been added since this boat was first built, IE smoking stacks, fireing torpedoes and magnetic pickups for colecting them. Also has working radar/moving gun + a home built bec.
Flag poles and flags/compas has been added on the superstructure.
Each motor draws 6amps at full power, I have measured the speed from one point to another at a spacing of 60mtrs, and timed at 15 seconds, but this is a bit fast for this boat as she starts to plane out of the water.
We sail her at New Brighton lake on the wirral most wednesdays. As the weather is now a bit cool I have just purchased a simular model to this at 1:48 scale 110ft island class USCG Patrol boat so I can look at them both in action when the weather picks up. Anyone wanting info can contact me via this website.
If your going to I of W it's worth calling into Westbourne Models on the way that's if your going along the coast.
If your going brushless be warned that the ESC's are a lot of money. I would recommend the Graupner one. I have one and cannot fault it. its a bit strange to program at first but once I got use to it no probs. You can have it for planes, cars, helicopters or boats, it changes the start up differently, I had nothing but trouble with some cheap ones until I went to Westbourne emptied my wallet and put it in my Huntsman by Precedent, the slow speed is fantastic you have so much control and when you open it up it is smooth. I put a water jacket on it and it is always cool no matter how I drive the boat. if you do go to Westbourne let me know, if you like, and you could come in for a drink (tea!) would like to meet you,
speak to you soon, Brian
