Good boat and fast. Watercooled brushed motor. Normal problem with commercial mini-boats is lack of proportional RC but this is fine. Battery life about ten minutes - low freeboard and takes on water but electrics/RC have proven resistant to regular swamping!
- ianed57Sub-LieutenantBrian,
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
- Captain-SteveLeading SeamanYep that's the exact model I now own. Have you any bids of it on the water ?Liked by marky and matthew lowe
So far have cleaned it and fitted a MabuchI Brushed motor of unknown power, but appears to work well at 6Volts running a 2 blade plastic prop 30mm 'S' type.
Havent got round to fitting radio gear yet, so have done tests as a free sailer, setting rudder on a slow arc and watching as I walk round pond.Will update as soon as next stage is complete.
This model has now been sold and replaced with a newly built Canadian Coastguard Griffon 2000TD built off a Mark Porter plan but using two Graupner Speed 600 motors, one powered by a 3000 Li-Po battery for thrust and the other on a 7.2v Ni-Cad for lift.
- Chris BLeading SeamanI have just got the plans to build this from MHA
Any info you have on your build, would be much Appreciated
good looking model by the way 😊Liked by Skydive130
I have decided to finally bring my Fireboat out of the closet and up for inspection.
This is the first of my many boats I am showing, I will probably show others in the future.
I started to build her back in 2006 after being off work and having a shoulder operation. She was not going to be a R/C boat, just a bit of something to do whilst on recovery.
I have a 34" still in the box unmade, purchased back in 1994 from Aerokits.
I drew round all the parts and then shrunk them on my scanner. She is 27" long I think that's
just fraction over 1/20th scale . She is almost all balsa except the 2 under skins that are balsa laminated with 1/64th ply. The hand rails are 1/4" balsa blocks I cut from a strip and the rail is ally tubing.
The mast is made from plastic strip from packets from the model shop.
When I returned to work she was put into the shed and left unfinished.
I stumbled across the Fireboat website and registered in 2009 when I was off work once again. This then made me think more about working on her again and I decide to turn her into an R/C model. So out she came and I fitted an Electomax Delta 480bb motor and a M3sonik esc.
I also purchased a couple of Robbe fire monitors, put them together shortening the nozzles and cutting the bottom of the base of to try to look a bit moreto scale. I know they are not the correct type but if I want to go down the road of getting them working then these ones will.
Then off I went to Wilkinson's and bought some paint. Then set out to paint her, as I brushed on the paint it seemed to be drying almost as quick as I was painting her. Dragging the paint I had just put on with next brush stroke. What a TOTAL DISASTER !!. I gave up on her and back into the shed she went.
2010 arrived I started again rubbed the paint down a bit and bought some Tamiya spray acrylic and started spraying, underside red, it seemed look all right. I used a nice new roll of low tack masking tape, taped up the underside and the decking and sprayed on the black on the sides. I thought that look all right. Took off the masking tape, which also took off the red paint and the dope from the decks. Another DISASTER. Back in the shed she went once again.
A couple of months went by and I was up in Norfolk on my own boat and watching the workers in the boatyard, ideas came to me and when we returned home, out she came and I repainted the sides
and then with red oxide paint I painted her undersides to make it look like antI foul paint. I used some white stripe to cover the join of the two different paint colours.
I had bought some roundels in Anglia Model Shop in Gorleston and some lettering in a shop in Norwich and after painting put these on.
Not looking fantastic but passable I was a little happier with her, but still not satisfied, back in the shed she went again.
Now after so much nagging from my brother out she has come, I've started again. He talked me into changing and trying a brushless motor and a smaller esc he had in his tool box from his helicopter he was shelving as its rota head was damaged beyond repair.
I have now fitted them and if they work I will change the esc to a forward/ reverse esc in the future at some point.
Sea trials are still away off more than likely in the spring, because the decking has yet to be painted. That will be the next job.
I think that's all for now, as I have probably bored you all to tears. I hope update as I progress further.
Just to let you know I'm Tom (alias BOATSHED).
- BOATSHEDCaptainHI Squirtgun, up to no she still hasn't changed, and is still unfinished.
I did take her out and try her on Clapham Common Long Pond, a bit of a disaster ☺️ , the prop that was on her was a 4 blade 40 mm, was a bit to big and would not steer and tended to react to the torque and pull one way 😭 .
I have since purchased three smaller prop's 20,25 and
30 mm 3 bladed brass props. will have to experiment with these at some point.
Sadly what with work and trying to get some work done on a classic car I have, I haven't had chance to do anymore 😭 .
Haven't retired as yet, that date isn't until August, but as the law has changed, you do not actually retire anymore I'm told from work, you either work on until you decide or you just resign now.
So I will get some more done soon but have just been to busy on the classic car.
Thanks for asking and when done more I will post it.
Kind regards Tom (alias BOATSHED )Liked by Inkoust
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.
Photo shows my RAF crash tender in the colours as it was when first built in 1956/57 from a kit. (Red tops like all fire engines, well I was only 9 at the time.) This photo was taken at lakeside in 1993 when I first joined the Cwmbran Modelling Society. The Second photo shows the boat on display at the Portis Head Open Day event in 2000 several modifications taking place to the overall look of the boat. in 2008/9 I decided for it's belated 50th. birthday to revamp the model and bring it closer to the real thing. Damage to the woodwork being repaired and a colour scheme close to that of the real boat being applied. Several new deck fittings being made along with new window surrounds made out of plastic replacing the cardboard ones fitted in 2000. New decals and correct flag also fitted. The model was entered in the 2010 society Chairmans Comp. winning joint first place with one of my other models. Photo 4 shows my model as she is to-day repaired once again ready to sail, after hitting some Ice over the christmas period 2010 resulting in a hole in the bow that almost caused her to sink.
The model over the 54 years it's been around has been fitted with single and twin electric drives and to day it has a single johnson 550 brushed electric drive via a 2.5/1 gear box run off two 7.2 volt racing packs in series. The torque generated being too great for standard plastic props resulting in me using 40mm three blade brass props. The motor controller is an electolize 15 amp unit and I also use one of their switch units to activate the water pump for the scratch built water cannons. The water pump being salvaged from a 1960's car washer system and still goes to-day.
Hope you enjoy the pic,s as much as Ive enjoyed this model over the last 50 years plus.

- larryshaw48Able SeamanDoes anyone remember the 'Triang' Vosper Air Sea rescue launch?
spent many happy hours on Letchworth town pond with that! - GreyWolfLeading SeamanHI Larryshaw48 🙏 Sorry for the delay, been down with a bug from before Christmas. Several of the Triang Vosper Air Sea rescue Lanches came up for sale before christmas on E bay listed under Vintage Model Boats. All seemed to be for sale with their original box and in fair condition taking their age into consideration. Never had one or needed one myself as the boat shown above has been with me from 1956/57.
