Pakinto Build

RG65 Class General Discussion (RG65)
21

A few finishing touches and all we need is the rig!
Hull – 325g
Keel – 700g

that is some great work

23

Thanks Pat.

A couple of small details on what I did:

  1. The loop turn around is a block tied top the rudder stuffing tube.
  2. There are two hatch openings. The port one accesses the electronics (receiver, voltage regulator, etc) and is covered with sail patch tape. It is not frequently accessed. The starboard one accesses the battery. It will be covered with packing tape when ready to sail.
  3. The switch is a Deans charging plug. It is on the hot battery wire. When plugged in it closes the circuit. It forms a waterproof through deck but is easy to turn on and off.

Well I had a chance to get Pakinto in the water this afternoon. stole a rig off the Ranger.
Good wind and some chop. This is a nice boat. will take 2 out tomorrow for some testing.Can’t wait.

please pardon some newbie ignorance here… but… you didn’t make up any internal bulkheads to strengthen the hull? is this not neccesary for this type of model? Im a little worried that such construction might leave the hull a bit… “squishy”

I’m also trying to understand how the winch works. is the jib and boom static and the whole mast rotate?

Also…any links to who you got the keel and keel box and rigging?

once again… sorry about the newbie questions. I really want to get started on this round ranger. and any info reguarding general boat racing boat construction helps.

The bulkheads are really not necessary. The way that these boats are engineered, the mast ties directly to the fin, so almost none of the loads are transmitted through the hull. Bulkeads would add a lot of unnecessary weight. These boats are not meant for playing bumper cars or sitting on.

I’m also trying to understand how the winch works. is the jib and boom static and the whole mast rotate?
The rig in Craig’s pictures is called a swing rig. The entire rig rotates, with the boom fixed to it.

Also…any links to who you got the keel and keel box and rigging?
Email Eric (ericr367@yahoo.com). He supplies just about everything from keels and keel boxes to swing rig kits (with sails).

Here are two pictures of the boat finished, rigged and ready to sail. Also, my next project, another Pakinto and another Round Ranger.

Thanks for the info!

I will say that your build here has definitely taught me that I’ve been way over thinking my round ranger.
I’m still thinking at least a couple of tiny bulk heads just for some rigidity. G-10 fiberglass board. I got that on hand and pretty much just enough for a little bit of profile. most certainly not needed, just a touch of a piece of mind.

I’m familier with a swing rig, theory at least. never built one or used one mind you, but I know how they work. the use of a winch servo is what threw me, looks like the connection point is on the Jib section?

could this also be controlled with a swing arm type of standard servo control? because I was thinking of just using a standard, or large scale servo with a arm to let the sheet control line out.

I’m going to assume that your mast rotates freely in that tube you attached to the keel box? do you recommend a swing rig for a newbie?

In any case, thanks for putting up with a newbie, your boat looks great! any plans for the finish or are you just going to leave it a the styrene white? Not to beat my own drum, but the guy that owns the box factory that does all the Packaging material for us in the beer mines has volunteered to wrap my round ranger in the breweries “livery colors”. essentially, he’ll be modifying the six pack graphics so it’ll fit on the boat and putting it on vinyl, the same stuff to make those billboard cars and busses and having his guy do up the boat. They do 1:1 boats as well and apparently the material is good for five years in that environment, on an RC boat? i’m sure it’ll last forever. :slight_smile:
it’s not exactly corporate sponsorship, but it’ll look nice I’m sure :wink:

Don’t feel bad Beergnome, I’m about as green as they come when it comes to this, but I’ve gotten some great help here. :slight_smile:

Here you go:

Lots of good information, thanks!

next step is hunting down a decent radio. I don’t want to harvest the radio out of my steamer, I have a bunch of Air frequency radios that the old man has been passing down to me.

I might just get another one of those $44 2 channel AM futabas from Tower.

32

Hi friends:
Here you can see the 1st Pakinto, sailing in the 2010 world championship.
cheers

Hi Maximo
This is the picture that got me hooked.
So far about a dozen have been mailed out, most to Europe.
Thank you for letting me do these. I think they are a quick, easy and inexpensive class builder.
At least 2 will be at the Regatta in Richmond Virginia this Saturday. I hope we can do her justice…

If you can stretch the budget a little further I’d be more inclined to go for a cheap 2.4 Ghz set - you may even be able to pick up something with 3-4 channels giving you more options if you move up in boat size.

Regards,

Row

35

that’s the idea in general. the wife just started working again, so I want a really nice multi channel 2.4 to use for surface and air.

I’ll be at the Richmond regatta saturday, they let me out of the beer mines for the day, but gotta be at the brewery by 12:30 to do the tour.

See y’all there! I’ll be the really big guy with the giant beard. :wink:

36

Good wind in the Regatta.

Something to look at Beer, http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXYWL8&P=7

This is the radio I went with. Comes with 4 servos that do well in an RG as far as I can tell (which isn’t saying much since I’ve just barely finished my first build). But it seemed to be a pretty decent value.

Or for a lot less money and a reduction in functionality check out:

Alternetively:

http://www.amazon.com/E-Flite-LP5DSM-5-Channel-Transmitter-2-4GHz/dp/B000K0WUNA/ref=pd_sbs_t_4

Just a couple of examples which would be perfectly adequate for simple 2 channel set ups, whilst having a little redundancy if/when you do choose to move up in size & want, for arguments sake, a jib trimmer or twitcher, or even an adjustable back stay.

Best of luck with the search & lets us know what you decide on when the time comes.

The following basic 2.4Ghz sets could be worth a look:

http://www.amazon.com/TTX404-4-Ch-2-4GHz-Tx-Servos/dp/B0043RGYQK/ref=pd_sim_sbs_t_9

Alternatively, this one, which looks very basic, is actually pretty good on the features front (if it’s the one I think it is!!) - most adjustments can’t be made direct, but if you plug it into your computer (or possibly smart phone) it has amazing functionality for the price point.

It is a good radio but that vendor is way overpricing!

Don’t forget to order the programming cable. Manual in the files section.
Also get a few 3 channel receivers- failsafe on channel 2 - mix to throttle channel and plug into sail servo. Gives programmable increased limits on servo throw too.
Also available from local HK warehouses.
