Title: Aerokits RAF Crash Tender
Post by: dodgy geezer on December 17, 2010, 11:54:25 pm
Now this surprised me.  http://cgi.ebay.co.uk/RAF-Crash-Tender-Model-Boat-Kit-Vintage-/170580572689?pt=UK_ToysGames_ModelKits_ModelKits_JN&hash=item27b764fa11

I thought that Jotika was quite close to producing their own Aerokits Crash Tender from original plans...? My experience is that Lesro are not always the cheapest, but they seem to be out first with this best-seller....

The performance of this newly-produced model has, after exhaustive experiment and testing, proven to be extremely fast and exciting on the water if fitted with an appropriate motor and compatible equipment.

taken from the description, I would be interested to know what "exhaustive testing" was done, and what the outcome was to achieve the "extremely fast" performance as I dont think any radio gear or motor etc is included, no mention of brushed or brushless etc,

The 4 footer Aerokits has a lot of prescence on the water and is a nice looking boat

the picture looks very  much like the boat that was being sold for he last few years from the Vintage Model Workshop group , just because someone is building a firefloat Mk2 does not mean it has anything to do with the old Aerokits one , it is a model of a  real boat. you can tell its not an Aerokits by the shape of the front roof .
good on them anyway,  people have waited about for years paying silly money  and spending hours re building, having said that some people prefer to do that than start from scratch they probably get a real buzz to see the nicely re built boat and think back what a shed it was.

Paul don't you have a static model of one, have you ever thought of towing it around the lake?

I just assumed it might be connected given Les Rowell designed the original Aerokits 46" model, and Lesro models had been selling the Aerokits plans recently (though I never said it was the Aerokits one  %) %) ). I know Jotika are in the process of putting out an Aerokits Tender. Looking at the kit I see "A 1950s revival kit from VMW" written on the box, so it seems likely that it is the Vintage Model Workshop one. Do VMW have a website?

No I didn't think for a moment that you thought it was a aerokits you are one of the people who have been dispelling that myth by putting plans together. I have built many aerokits fire boats over the years and am less and less a fan of the construction methods used so if someone comes up with another way of kiting one great. there is a chap Mike Cummings connected to it that comes on hear and on the Fireboat web site
there  is a phone number hear but don't know of a web site

Certainly looks like the box of a Mike Cummngs kit... I have seen old and very banged about 34" fireboat sold for £150...
Maybe its about time somebody started a Vintage model boat society.... like SAM for model aircraft....

I thought I would start renovating a 46" Aero-kits Crash Tender that has been sitting around far too long seeing that Lesro are now offering them at a premium price. Question:- anyone got a 46" version as I need some advice regarding the power plant. IC is out, not allowed on the pond - scares the horses!! I would prefer brushed as the brushless set up seems a bit hit and miss. I tried brushless in another boat but could not for the life of me get the thing to go. Something about programming the bits together. So a challenge, a brushed motor set up that will make the boat go and plane well at speed. Appreciate any advice available. :} Thanks

Hi, go to the fireboat website, there is a section regarding set ups, plenty of info there, and some videos of the boats running. I will soon be starting my renovation of a 4 footer, and plan twin brushless, you could also use the 900 size brushed motors, big and heavy, depends how fast you want it to go really :-))

So you can make a 25lb boat plane on 4 amps.?

I DID NOT SAY IT PLANED BUT HAD A NICE BOW WAVE  AND AT 80 YEARS OLD CANNOT SEE THE POINT OF PULLING IT QTR OF A MILE  FOR 10 MINS OF SPEED WHEN I CAN NEARLY GET 3 HRS OF ENJOYMENT OUT OF IT. NOW THAT THE SUN IS SHINING HERE IN CORNWALL

Ok for a start who said we get ten minutes ? and if you look at the video of the full size boat and the way they perform and the amount they are out of the water it is nice to try and copy, on an average run we can get 25min with varied but fast speeds, after that we play with a slow boat while the batteries charge or are changed.

by the time i have pulled the boat no energy to carry a spare battery or charger as i said quite happy to poddle around at a slow speed  i1 8 1 said he wourld rather have 10 mins at speed  any how went to the lake to day a very nice couple of hours with my boat sun was out couple of my old mates as well what more can we ask for

Shame on you Regiment, what right have you to dictate how you get enjoyment out of your model?  >>:-( Everyone knows that the fire tender always hurtled about like a scalded cat.

  Jankers for you sir, spud bashing at the cookhouse for the next five days  %)

funny you say that about spud bashing as an ex cpl raf cook i was the one detailing brats ? for spud bashing good job in this weather  nice and warm in the cookhouse any how if my boat went faster than 2 mph would not be able to catch it looks like i have upset the speedsters oh dear  i will hold my hand out for a smack

hi ukboats how about using a 850 motor with 50mm prop on 12volt is a good place to start

Actually, as it happens, if you would care to look at the attached pathe news link, the RAF crash tender, as modelled by Aerokits, was intended to perform like a scalded cat, Given how old the boat is now, that was a very impressive turn of speed, and it could stop in its own length. Also, look at the crew, its a common  misconception regarding the size of this boat, it was actually quite small.

http://www.britishpathe.com/record.php?id=47447

Regiment, you enjoy your 3 hrs, I just happened to comment that I like to go fast, for a short duration,

UKboats,  Back to the original question, yes it is possible to achieve a great performance on a brushed motor, I would personally recommend a graupner 700bb turbo, 12v version if running on direct drive, and run it on its maximum voltage of 19.2, its very good, with a 40mm  "x" prop 2 blade will run for 25 mins flat out. If its too fast, and you want longer run time run on less volts. I run mine on a 8.4v graupner 700 bb turbo, but with a 2:1 gearbox, 19.2v nims, 45mm 3 blade cleaver prop. These set ups are tried and tested, , it all depends on the performance you want really, plenty of video on the fireboat website with setups, so you could actually choose what speed you want, and duplicate that setup :-)) hope that helps

I was impressed by the speed, and the maneuverability. But I had read that these things could also stop in their own length, and so I wondered why it pulled up at the flaming target, started spraying it with foam, and then continued to drift past it, making it hard for the foam operators to keep on target....

Post by: red181 on January 12, 2011, 09:49:10 am
maybe because it was testing, if you look closley, that is not RAF crew, it was actually Vosper personel, and the boat is flying the pennant that at the time signified "vessel under test, may deviate from course" (or something very similar!), I think it was the "A" pennant, blue and white, which today has a different meaning, I think now its "Divers in water" ,

Whilst it could stop in its own length, I hardly think any boat is going to just stop dead and not "float" :} :} :}

I know my old seaplane tender 1510 (now in bits and not restored as I though :( )
had a great turn of speed,when it was on plane it felt more of the hull was out of water than in it. It could pull up quickly by sticking full into reverse but you had to know what you were doing.
