CP. Great pictures!   See, it can be done. I have almost finished mine. We will have to have a race sometime.   Did you glue a combing around the hatch you cut out the deck underneath your superstructure to stop water getting in ?? And if so what glue did you use, I was wondering if plastic weld mould be a better choice than araldite. I am hoping my waterline will only be about 1/4" above the painted waterline.   Ashley

Hi all,

 If that is flat out it is very close to the speed that mine attained, a good scale speed that looks just right on the water. Very nice pictures and well done Chris.

Ashley, I used Plastic Weld for all my conversion work on this model, it makes a much better joint as it does what it says, welds. If you read my article, I used scrap pieces of the hull material melted in plastic weld solvent to make a filler which is of course the same colour as the hull, this was used to set in the shafts and fill other areas that required it.. The grey material is also meltable to fill or reinforce those areas on the superstructure such as the coaming.  Araldite is of course a fantastic adhesive which I use for many other applications……the thread continues!

Regards Alan…

Hi all,

Yes it flat out, with a 12v set of 10 1.2 rechargerables and with 23mm brass props. race props would be good but they don’t do 25mm .. do they? 

Well it’s still not finished, I cut the stem holders to short and when underway water seeps in, so either try to lengthing them or cut them out .

Yes Araldite .. it will be making a come back once more.

[ashley needhamParticipant @ashleyneedham69188]

Chris.More speed could be obtained with a pair of 380`s(Maplin again, ready supressed and with leads attached) , they would go on as straight replacements, and using a 6 or 7.2v batt pack. This would lighten the boat a bit (by halving the number of batteries…use 2.5mA hr types.. I am wondering if transom trim tabs or a flap would make a difference here as well. You could try filling in the semicircular ex-prop depressions for a flatter bottom and so better lift charcteristics.  Ashley

[ashley needhamParticipant @ashleyneedham69188]

AAArrrrgh… I get my lifeboat  all ready and turn up at the pond to give that Chris geezer a GOOD THRASHING, in the freezing cold and rain this morning, after seeing the performance of his boat a few weeks ago..but the B  has apparently taken some BAD ADVICE from yours truly (regarding not underpowering things) and fitted a pair of SPEED400`s !! 

OO er. I think Chris`s previously posted picture is well out of date now and should include some skiers behind it !         Oddly enough, despite undeniably being a BIT faster than mine, it wasnt  as fast as it should have been with 2×400`s, considering my toddy speed280`s. It has to be the hull. We have both filled in the depressions beneath the hull and visually there is hardly any difference between the two boats. I think there is a case here for some fine tuning, and I intend to fit a full width shelf at the rear about an inch wide to see if lengthening the hull makes any difference. The nose lifts up very high when power is applied, and there might be a case of shifting some weight forward, however this would affect the look  of the craft at low speeds. As it has a nose up attitude when flying along, then of course when you stop engines the whole craft nosedives in a very unseamanlike manner when slowing down.Ho Hum.I know its not supposed to be a speedboat,but dont care.  Then there is the matter of excess hull lumps and bumps……    Ashley

[Chris PearceParticipant @chrispearce30862]

Yea baby Yea, Well you did say to upgrade abit, blame it on Malcolm at Cornwall Models…..

Your right re the hull, I will stick on abit of boarding at the back like yourself, I added some card 1" to stop the water from entering in, works well.

The need for speed what ever next……mmm

Want a rematch soon

ChrisP

[ashley needhamParticipant @ashleyneedham69188]

When I have altered mine, your`e on !     I may bring down to the pond my HMS Midge topedo boat and you will see just how fast a boat can go on just one speed 400.     Ash

[Chris PearceParticipant @chrispearce30862]

Ok sounds like fun! I fitted some trim boards…. well ummm it’s a bit more stable but it appears to be riding higher still, with a good inch or 2 of the keel in the air? not so much splashing around around the back.

CP

[ashley needhamParticipant @ashleyneedham69188]

CP. You know what it must be then,

###############  LIFEBOAT PURISTS TURN AWAY NOW ###################

those big anti-rock "keels" either side of the props, they are stopping water being displaced out the sides and thus causing "bunching" of said water and stopping the thing planing. They will have to come off. My mini cutty tool is out as we dont speak, This should cure it, the trim boards will then have the appropriate effect. I also think a shift of weight forward might be called for but this will give the boat a nose down attitude at rest. Might be a last resort in the quest for speed, sorry, appropriate performance.   Ashley the butcher.

[Len OchiltreeParticipant @lenochiltree67043]

What about fitting a Hydrofoil at the front to bring it up.

Len. 

[ashley needhamParticipant @ashleyneedham69188]

Len, youre the man !!!     Unfortunately the front IS coming up and theres the rub. Trim tabs on a boat lengthen the effective hull on the water and move the c of g forward, but Chris has just tried that and it appears to make only a small difference. I have trimmed the keels off now and will hot-glue a trim board on the back to try tomorrow morning. Hot glue is good stuff for this sort of thing, as I will be able to pull the trim tab off easily and see the difference, if any. Ashley

[Chris PearceParticipant @chrispearce30862]

Hi all,

I have taken off about 1.5 " from the rear 2 keels, so stops just before the props  it settled down a bit, looks good.

Will see ashleys on the boating pool tomorrow

[ashley needhamParticipant @ashleyneedham69188]

Dudes. didnt manage to put trim tabs on. No noticeable difference to trim with the side keels off, Chris`s boat runs noticeably flatter now than mine, he has put three tabs on, i am going to go for a full width jobbie as power is not an issue as regards increased drag. 1/4 inch of ice on the pond today, only the overflow stream clear and a small corner of the pond it connects to. Good selection of boats. Berenger was using my HMS Jersey Island class patrol boat as an icebreaker (as small boys are wont). Good job the hull is super strong. Ashley

[Alan PooleParticipant @alanpoole81825]

Ah, an island class, shall we go off on another tangent and continue the thread with these models, I do have some experience with her majesty’s patrol ships.

Kind regards  ..    Alan.

Where is your water and what club AshleyChris  ?

[Len OchiltreeParticipant @lenochiltree67043]

Hi Alan,

And yet another Tangent, on the TUG Forum, a Dover Tug was talked about and I said things were a bit touchy at Dover at the moment, perhaps you could enlighten people as to what is happening there?.

Regards,

Len.

[ashley needhamParticipant @ashleyneedham69188]

Alan. We dont belong to a club as such. And as per Lens remarks above, for good reason. The nearest model boat club to us is a bit standoffish and majors on sailing/comps. No good for ush Bushy Parkers who only want a bit of fun. A few interested bods gather for a sociable few hours boating at Bushy Park, near Hampton court on a Sunday morning 9 ish, to trade banter, insults and rubbish each others builds. Nice pond, car park 30 yards away, the boating pond leads to a largish lake..unfortunately populated by fishing men in season. Ashley (and Chris for that matter)

[Len OchiltreeParticipant @lenochiltree67043]

Hi Ashley,

No, I meant in the full sized Dover Harbour!.

The Dover Model Boat Association is a lovely close knit and friendly club.

Len.

[Alan PooleParticipant @alanpoole81825]

Hi all,

 Yes, as Len says, the Dover Model Boat Association Club is a lovely club and well supported. We would be pleased to welcome any model boaters down for a friendly sail with us at Kearsney Abbey.

 The full size Dover Harbour, well I could not possibly comment, as one of the workers involved it would be improper of me to do so.

The DHB did however hire in a tug during the dispute, it was the Osprey Fighter, shall we say it had it’s limitations!  

Regards  Alan…

[Chris PearceParticipant @chrispearce30862]

Hi Alan,

Well I might just do that in the future, mmm carving up those ….  with my Danish coastal trawler The Bent.

Just found out why my Seven wasnt that fast… only one shaft was turning, now both 400 are on tap..

see you all soon.

CP

[Alan PooleParticipant @alanpoole81825]

Hi Chris,

 Watch out if you do come down, there are submarines lurking in Kearsney Abbey just waiting for a Danish coastal trawler to be hunted down. might have to be a deck gun job though, too small to waste a torpedo on !  

Have a good one.

Regards Alan

[Chris PearceParticipant @chrispearce30862]

Hi there Alan,

Now watch out for danish trawlers, some are armed…. 20mm orks, depth charge racks 50 cals and sound devices…. mmm oh yes radio freq jammers!

 all being equal see you on the pond…!

[Chris PearceParticipant @chrispearce30862]

Yet another up date,

I have taken out the 400s, this due to the very high planeing..ie 4 inches of keel showing, and with so much thrashing around it was forcing water up the rudder stems. This lead to a cut out and a cup full of water, being removed.

Now with 2 385s, well back to square one.

 Hope you all had a good Christmas.

ChrisP

[ashley needhamParticipant @ashleyneedham69188]

CP. The MFA/como 380 motors sold in Maplins are not quite as speedy as the speed 400`s and fairly cheap, but much faster then the 385`s.Might be worth a try, they will fit straight on. Try fitting a deeper full width transom flap instead of the three bits you have now. Ash

[Chris PearceParticipant @chrispearce30862]

I will have to try that, the water still comes in… still not sure to put in a single 400 and leave it at that. bah humbug.

CP

[ashley needhamParticipant @ashleyneedham69188]

CP. Put the thing in the bath and run it whilst holding the back down to stimulate its normal attitude on the water and after a few minutes you may see exactly where the water is coming in from. You might try giving the rudder posts a good greasing to stem any inflow from them. Common consent has it that filling shafts up with grease is not such a good idea, but it wont matter for the rudders. Ash
