Just as a thought, whilst not entirely scale, if you are going from 45mm props to 55m props that's only 5mm each side so you may just have enough clearance anyway, or maybe extend the prop shafts by say 1 inch and this may give you clearance to try the bigger props without significant surgery.


Cheers

HI Geoff well i wish you was right on this but im  afraid you are wrong sorry to say no i have fitted on 33 mm props what shew on the plans an they are nowhere big enough so i was goin for 45mm props an yes i could have just got away with them but then i contacted my boaty m8 who has bought my hms edinbough type 42 at in 1/64 th scale an 7ft 3" long an a fairly heavy model as she sailed great an asked him what size props i fitted on her an he replyied that the props are 55mm so i think to be on the safe side due to the cost of these props im goin a bit bigger at 55mm an hope they will be enough as this is the last throw of the dice as im not throwin any more money at this model as this is the most exspensive ive ever done but due to size of her it a hit an miss job on gettin things right first time which hasnt happned an yes the surgery will have to happen all 4 prop shafts drilled out an new big motors fitted an then maybe new A -frames an them shafts all reset should take about 6 months i reckon
CHEERS chrisb
cheers Geoff for takin an instrest

Chris
I still think you are wrong to rip it all out, without trying the new motors, I notice you said 33mm props I take it that is a typo error as I have just looked at my plans and 333mm is for a 1/96 scale.
Try the motors first with current props you may be surprised, also its what lots are telling you to do.
Not criticism, just trying to save you doing lots of work that you don't need to.
Have you got through to Cornwall models yet?


best wishes

I Bob no shant bother with cornwall boats as jen rang 5 times an no answer but a boaty m8 came to see me today an he was horrified when i said what i was goin to do an he thinks that yes the present props are for 1/96 scale tiger like he is building an he says go with the 45 mm props as with them big motors they should be enough to get tiger goin an just make the rudder a bit bigger but keep it in scale Sooooooooooo ok Bob i'll listen to you all an fit 45mm props an i then wont have to tear up the hull an he is goin to get me some props from prop shop hopefully so see what happens as no i dint want to cut the hull but i was thinkin i was out of options an cheers Bob for your intrest an post ATB TO YOU SIR

Great News Chris, yes I have been interested in the build having built it twice  %% .
Glad you are going to try props and motor first, shame to waste all that effort.
Good luck in the future and hope Jen is still ok.
very surprised about Cornwall Models, they usually answer straight away.

Hi Chris
Yes I did have a build but when photo bucket changed it wiped all my images, so there is only one page and that is dealing with the divers lines I painted on her.
Motor set up two torpedo 850 motors with each having its own esc, one on each up and down stick, motors mounted along side each other, so nothing really out of the ordinary.

OK Bob what a pity  on your bristol build  <:( yes that photo buckect took a lot of my NIMITZ build pics off as well  >>:-( <*<  but im glad i have found free imgbb site for pics very good site that is
an well on tigers motors  i managed to get some motor fixin bolts to hold motors in their mountins an im just goin to try just 2 big motors an the 2 smaller johnsons motors with the new bigger 45 mm props when they come as my m8 ordered them for me from prop shop an it was a surprise really so will sail with these an if still not enough power then i'll remove the johnsons motors an fit the other 2 big motors an then see how she goes an pic of them big motors all fitted in

Hi Chris
Nice looking props, that rudder looks about the same size as the 1/96 on my Tiger, so if that's case could be why it was not working 100%.


Good luck, get out on the wet stuff while it last :)

Chris, That rudder should do the trick. I hope that your servo can stand the load! A quarter scale servo might be in order. :} Best of luck on your next trial.

HI Akira yes i only hope so but you may have a point on how heavy a load that rudder may be under an if i need a bigger servo then that will have to happen an i will get a bigger servo in fact i think i will fit in a brand new servo as the one ive fitted is an old one many thanks for pointin that out Sir cheers
