I have a colleague at work who is also making this kit.
He asked me about what motor etc to put in it as he is still new to the hobby a d was going by what the manufacturer said and is having difficulties. I am not much help as all my stuff is slow or tugs, fast things I have now experience of.
He would rather go for something brushed and prefers it to run off of NHMhs which he has shed loads of rather than Li Po's. Oh and being a dockie he wants it cheap, as cheap as possible!

Hi,


I'm not sure I can be much help either but I did speak to Cornwall Model boats (who supplied the kit) and as a brushed set up they suggested....


JP Pro Power 600 motor
Mtronics Viper Marine 15 speed controller
8.4v 3800 NiMh Energ-Pro Battery pack


Maybe some one with more experience can shed more light on this...

Hi Martin,
It's a CNC  one piece supplied in the kit all I had to do was put the finish on i. The deck and engine hatch are the same but must be honest and say I was surprised it wasn't just plane mahogany sheet as it's the cockpit floor and when built up with seats etc. can hardly be seen. Nice touch by Aero-Naut. I must say that I've been very pleased with the quality of all the timber in the kit.

Cockpit not finished but getting there, takes so long with the drying times between coats of yacht varnish...but hopefully worth the effort

I've been putting this off if I'm honest but went ahead and wasn't as bad as I thought it might be (a first for me) glassing the hull....










Engine hatch

Looks good mate,tip for you when glassing if you flip boat upside down and sit her on something you can drape the cloth over her in one piece if you get thin enough cloth,yours looks ok and i think it might have gone on in one.What i used to do is do transom first let dry then trim then do bottom and sides in one then trim off at transom and deck  job done.

Good tip!! I did read about it being done as you describe but wasn't brave enough to have a go as first attempt lol...maybe on the next one... :-))
I did the bottom in one piece then the sides separately followed by transom... so a long winded way about it...


Cheers

Yea so long as you use a nice cloth  like a twill weave it will then form round the contours just fine even at the bow,all you need to do is have a practice by laying the cloth on dry and test it ,you will see how easy it works  :} then do it for real .

After glassing the hull I applied two coats of Z poxy resin then left it to dry and settle for around a week/ten days. Flatted back, masked up the mahogany and fired a couple of coats of Halfords primer/filler....





Wet flatted again





More filling etc.








Today...








Final pics are where I am at today, not perfect but going to leave like this for now and final fit motor mount, prop shaft in place and make watertight (have trial fitted it all before) and then continue with bottom hull finishing and the many coats of yacht varnish to the mahogany....so you may not hear from me for a while  :}

Not much to report but still varnishing the hull, I'm leaving it 4/5 days to harden between coats and then light rub down and go again, it's frustratingly slow but hope it pays off.

Super thanks Dale

I'm working on a Classic from Aero-Naut right now and when it's done, a partly started Jenny is waiting for some TLC and your solution look as a nice add-one for that.

Hi all,
I am installing a water cooled set up at the moment and would like to hear your thoughts on where to position the intake pipe. I have mocked it up as in the photo but nothing is glued yet so can be moved.
Thanks
Dale.

Hi Dale,

While having the inlet as deep as in your picture, you'll have a lot of water through your tubing (make sure the pressure won't blow them from your nipples), a speeding fountain might be the result..., it'll also add a lot of drag, slowing you down.

As the hole is already there, I suggest you raise the tube so only the slanted section peeks out, in combination with the propwash this should provide ample flow with the least amount of drag.

Tip: bend the tube inside the boat so the height the water has to rise before going to the ESC and motor is as little as possible, and you'll still have flow when you're crawling along.

If you want to be sure to have flow under all circumstances, put the outlet in the bottom to, but slanted towards the rear, creating suction when the boat moves.

I have this pressureless system in my fast electrics and in my scale boats, works like a charm.

I added two picture of the inlet and outlet on my 110 cm M.A.S., notice there's virtually nothing sticking out from under the hull.

Regards, Jan.
