WELL Ian it may be that they are not sure themselves as to how corse a pitch them props are as i dont know as the one i put on here looks great but accordin to a guy on mayhem he says they are not corse enough so not as much thrust as i need so it a case of buy an try an if not right send them back for more corse a ones but the shops will only do it a couple of time an it costs to keep sendin them back an forth so for the moment i'll wait till my boaty freind comes back from his holl an i will consult him an see what he says
cheers sir

I feel for you Chris as it looks a bit like the "suck it and see" method at the moment. I would imagine there are guys out there with the knowledge you are needing but finding them might be easier said than done.

Chris,
I'm sure you will get it sorted. Hope your mate can sort you out. This is just my thoughts but will a coarser pitch make the motors work even harder pulling more current?Comment

OH Gosh Ian many thanks for lookin here an i was lookin at the pitch of the props an i havnt a clue TBH so as i will say wait till i talk to my boaty mate as i dont understand how this pitch numbers work is it the higher the no. the corser the prop pitch on the blades ? cheersTry here.

YES Andy how very true what you are sayin but the point of it how much will i have to spend to get the right props thats the question
cheers
chrisb
well Scottie at the moment i dont think the current matters as i have heavy duty fuses an batts an same on ESC an same on them monster motors if i fit them an if i can get 15 mins worth of sailin before it flattens the batt it will be worth it as i can buy another batt so twice the sailin time as them batts are not to dear what costs the money are these props as they are a specialist item as when they are bein made they have to all be at the correct pitch on the blades an they must be finely balanenced or the prop will shake an break the bearins in the prop shaft then more trouble TBH I just dint realise how lucky ive been on all them other ships oh dear
cheers

Pitch is simply the distance the propeller would move in a line for one full turn. So a pitch of 46.1 the screw would travel 46.1 cm per full turn. (Ignoring slip.)
So the higher the pitch number the further the screw will travel.
Silly question but have you checked the rotational direction of the props, so both starboard props turn the right way. If you have a lefty and a right on the same side, that boat ain't going anywhere lol.
I know someone who did itComment

WELL Ian after building an sailin 7 other big models i have never put a L/H AN A R/H PROP on the same side as its easy to spot i just look at the way the blades are bent so NO on one side there are two L/H an on the other side its two R/H PROPS goin in or out but IN OPPISITE DIRRECTIONS SO ALL GOIN INWARDS for forward thrust an maximum thrust through the rudder a very good qeustion all the same but one ive never been guilty of an as for pitch Ian i thought that the pitch of a prop was in the angle of the blades how far they are bent in to the prop boss from 90 degreess up angle ? as it shows that on mayhem pic
but many thanks for your help IAN as sooner or later we will get there

The chap that did it had been building ships/boats for 50 years. Oh and he was a boat builder by trade... Anyone can make a mistake when they are flustered.
It is but the distance that the prop travels per revolution is a much easier way to visualise it and it is infact how places like Mercury and Volvo/penta explain it.
If had just said that the higher the number the coarser the pitch, would you have been any wiser?
The pitch can be measured but is not that easy so I will leave that to your cleaver mates at Mayhem.Comment

HI Again Ian an yes anyone can make a mistake an to be sure ive just nipped upstairs to my model room an looked at the props on my tiger an they are all fitted correctly so there is no L/H an R/H fitted on the same side so that is not the problem an yes i would have understood if you had said the higher the number the coarser the pitch of the prop so more thrust thats right isnt it ? so ive now learned from you sir on that as ive never had this prob but yes i know that i need bigger props an what ive learned from you Ian will able me to look at the list on the prop site an look for a higher no. but wheather the prop coarness will be enough will be pot luck if you get my meaning but thank you very much sir for this info

Its a curse isn't it. I have pretty much given up buying from England and other places out side the EU. Yes OK there is a lot to choose from in EU, But still a pain.
I want a part for my Yamato, It can only be found in the USA where a guy 3D prints them. The part costs USD19.50 but postage and duties to send it here USD25. So 42 bucks for a 20 dollar part... Nope. Oh and then there is the handeling fee at the Danish end! Pirates the lot of them.Comment

AN Ian exscuse me on this but on that prop site all the prices were in eruo 's now please how much is the english pound against the eruo ? is the pound worth more or less
