Hey all,
have been lurking on the forums for a while waiting for my account to be activated, but now all is well :)
I have zero experience with RC boating and recently fell for the temptation and got myself a MG.
Having spent some time on the forums reading I also picked up from my LHS the rudder bracket and rudder parts for the Impulse 31, because when I looked at the two boats side by side it looked as though I could use the Impulse rudder parts to offset the rudder on the MG, which I understand is a good idea for keeping up the speed in turns.
It was mostly a bolt on fit except for the two holes in the original bracket that needed opening out to 4 mm to fit the screws from the impulse that where the only ones I had to hand for fitting. One of the screw holes had to be enlarged slightly for everything to bolt up nicely. Pictures are attached of the result.
Here come the questions :)
1. Does this rudder config look ok?
2. I currently only have a pair of hard case 2s 4000 Mah batteries (35c), since these can deliver 140 amps I am assuming the should be fine for the boat, at least to start with? Is it normal to use hard or soft case pack for boats? I assumed hard case would be better as the casing is more robust in the event of a crash so this is what I got.
3. I am also aware that the stock plastic prop is not great and got an alloy prop with the same dimensions as the orig plastic one (1.6 x 2.5) 40.6 mm diameter. On the bag for the prop is a lot of information that I don't understand:
30%PH___50%PH___70%PH____90%PH
30.55_____47.34____62.58_____77.02
average PH___propeller hub___dog drive
54.38_________8.00_________3 mm
What does all this mean? could someone explain this to me a bit more?
4. is there a good guide to sharpening and balancing a boat prop online that someone can give me a link to?
5. I see a lot of different recommendations for props, but the number don't mean anything to me. is there a convention for how the numbers relate to the props diameter and pitch? If so would someone mind explaining it to me?

Sorry about the crappy quality, but only had my phone handy....
Look forward to hearing from you all, and hope my questions are not too dumb....
