Balaenoptera Musculus. Upgrades?

[masonis1]

There you go. Have you done other work?

[seehuusen]

Hi Mason,

I haven't done anymore work on the boat, I'm waiting until friday to get paid :p
Then I'll put an order in for rudder, stringer, dremel (needed for the inside and other work), motor mount, servo, and possibly the motor too, dependent on availability of the right Kv and size motor...

Cheers
Martin

Water Cooling Jacket for 36mm Brushless Motor

ESC:
Not sure, will update

Props:
???? 33mm - 36mm at what pitch? 1.4? I want to buy a small selection of props, preferably plastic, that I can then test out, and buy the better cnc prop after that...

What do you guys reckon?

Cheers

This boat really doesn't need more than a 60a esc

[masonis1]

My pitch is also 1.38 I think so 1.4 would be good

[seehuusen]

sweet!! :) Thanks Mason, I'm about to order all of it on my lunch break :)

[masonis1]

When's your lunch break. It's 615 where I live

[seehuusen]

LOL, I'm in Australia mate, it's 2.30pm now here :)

I just posted updates to my thread on the other forum, I can post in both places if people want?

ALL the gear needed has been bought, ended up costing me about AU$300 all up, which was a little more than I planned to spend... I've got a theoretical speed of 86 km/h at the moment, so I should be able to meet the 50+km/h as I intended :D

I'd like to see it here too plz

[seehuusen]

a bit of progress today

I went to the local hard ware store and got a dremmel copy, very happy
So I got rid of all the little bits inside the boat, and cleaned it up

Then I made a new transom from some 3mm ply, which I fibre glassed into the boat to make it a bit stiffer and to have somewhere stronger to mount the gear

Pictures attached, it's all curing right now

Cheers

filled up the holes on the out side, hoping it will make it a bit more streamlined :)

Looks good. Nice work

[seehuusen]

a bit of an update...

Transom is finished, rear holes blocked and sanded.
The cast holes are filled out
I've made a piece of ply fit as a floor, to stiffen the boat on the length. It will be glued in place
I also painted the bottom outside of the hull, and it came up sweet :D

Cheers
Martin

hey guys

I made a servo and Rx box on one side of the hull.
I don't really like the balloon setup, I can't seem to get the servo to sit 100% still when it has a balloon wrapped around it, so I made this, it'll be water proof... as much as a baloon or glued up glove anyways
...and how is this for close on the weight, ESC weighs in at 105g and the servo, Rx and the wooden box is 103g I'll do a final calibration once in the water, but that's very close

a few pics of the progress so far... I think I'll be waiting on hardware, it should all arrive this week, hopefully
