Thanks for all that input folks = very interesting.
Firstly when I was saying S50, it is now obvious I should have said P50 (as in std pitch)
(I used to use the Mocom alloy props from PMB on the CMB powered multi, either 2023 or 2024)
Re the motor,
It is on the large size, but I like having power to spare
(and it is the one that came with it, so it can stay in
)
Re the rear decking,
Yes I did find some pics of what it should look like on the Fairey owners club site and at some point I might make it look a bit more "scale". (there are some great pics on that site
) On mine the tank does look as if it was made from a brake fluid can or similar, but there is plenty of room to make the rear hatch more scale like.
Re trim & Props,
I have done the first, and as yet only, trials with a std pitch 50 and actually the torque roll in a straight line is not at all bad.
Also, at speed the boat did keep it's nose pretty well in the water and ran nice and flat,
however the trim tabs did seem to have a lot of "down" on them and at that time I left them as they were, but I have now let them come up quite a way to see what effect they do have on the trim. = might be interesting, esp as the next "experiment" will be the X55 prop
Re the rudder and shaft
Aye, I have seen the rudders with the extra length at the bottom on some Multi racers, this does have what looks like a pretty long, high aspect ratio rudder fitted, might experiment with other shapes at some point.
The shaft is a bit odd to me (might be just me there though) as it is a flexi that runs in a straight tube.
The angle is pretty shallow and a 55 prop just clears the hull (that's good isn't it ?)
Just after I bought the boat I replaced the shaft as the old one was a bit rough.
It is a non standard one and I got very good service from "Model Marine Supplies" in Torquay (
www.modelmarinesuppies.co.uk ) in supplying a custom one that was made and delivered all in 24 hours !
I lubed it with some light grease, but will remove it after each days use to re-lube and check it.
Comments on the shaft and lubing welcomed
Nice forum folks
