Dick, wouldn’t 2:1 sheeting give exactly the same torque problems as lengthening the servo horn? If it doesn’t, you would seem to be getting something for nothing (twice the movement, same torque and speed).
Hi all
i just wanted to post this pictures taken a couple days ago. This is the new boat and as i write, all the work was scraped because i was not happy with how it was turning out… dick, on some of the pics you will see the 180 loop made from the ink tube.
New deck is coming soon, new transom also and some improvements to how the little things are done, new servos foundation and a pullpull for the rudder… new hatch, deck probably will be glassed, less stuff above deck… things like that… or a lot of things like that…
An advice… take this pics as “things not to be done on an RG” LOL!!!
Cheers!

Wow, all into the scrap bin?? I wish I could build half that good?

The S125 1T is more than enought for Rg, it is used for many sailors here in Chile. and 92 oz. at 4.8 v. is great.
Gee -
maybe I’m expecting more torque than I need. Of course dealing with 1 meter boats on up to 1.2 meter and sail areas up to 1400 sq. inches might tend to suggest “overkill is better”.
My winch - at 6 volts is rated at 133 oz. in. and it just seemed I could hold the mainsheet from oving with very little effort. Then again, perhaps “MY” holding effort translated into the range of 30 knots or so…
I guess I can theorize all day - maybe I just need to throw on a set of sials, connect everything up and take it to the water and see if winch is strong enought. I just expected a bit more pull on my fingers when holding on to the sheet line. After all - the thing is rated at 106 oz. in. at 4.8 volt which is much more than the references provided by our above “southern” neighbors.
Dick, trust me… it is an issue on where you locate and at what angle is the line to the main sail from the winch at the deck… now with your hitec u have more than enough torque anyway, which sometimes is necessary by the way…

Hi German -
I will just proceed and give it a try “as is”.
Talking with a friend here at work and he put it into perspective for me …
- F-48 multihull has 1400 sq. inches of sail area
- MultiONE multihull has 1100 sq. inches of sail area
- 36/600 monohull has 600 sq. inches of sail area
- RG-65 has 220 sq. inches of sail area - DOH !!!
That’s only a third of the sail area of my 36/600 boat! Once I realized this, I will now concentrate on amount of sheet travel first - torque second. Sometimes the trees can’t be seen due to the forrest !
I was so focused on moving huge sail areas, I never even thought about the fact the RG has a “tiny” sail in comparison. I probably would have over-engineered to the point of a monster 1/4 scale Hitec 815BB and still worried.
Appreciate you bringing me back to reality.
And beer wasn’t even involved to blurr my vision!
Thanks
Dude… beer sometimes put things into perspective… like finding trees on the forrest!!
and thank your work buddy… it never occured to me comparing the sail areas with other boats… and it was sooooooo logical!!!
Anyway, good luck with the boat… 2nite or 2morrow ill put new pics of my new layout…
Cheers

If you haven’t seriously “ash-canned” the boat, I have a feeling the hull only - less all your fittings might prove to be of some interest if you put it up for sale. Keep cost low/free to allow for shipping costs, and it might find a home. Especially if you were serious about dumping it.
Just a thought.
Hiya Dick!
naaaah, the hull is being recycled as only the deck was dumped and burned “viking ritual” style…
Now seriously, yesterday I glassed 2 balsa boards for the deck and made a new foundation for the rudder servo and winch. This will be attached to the keel box and framed to the hull sides with balsa for lateral strenght. The rudder is a keeper and i need just to define its lenght. Keel is 3mm aluminium shaped a little on both edges (my glassing skill suck big time so not worth even think of a frp keel).
I have the locations of the mast from the transom and other measurements for this hull so work will be fast. The mast is from the old boat and the new sails are on the mind of the builder… Yet…
Pics at nite…
Cheers

Er, 2250 sq cm comes out to 348.75 sq in. I’m not good at this, I just spend a lot of time at:

Thanks Earl - I already said it earlier … “DOH !” in my most Homer Simpson like voice.
:spin:
Hi All!
Only to show the new concept… as the pictures got small enough just for that (im sorry!!! i have no idea why they ended up at this size). The angled balsa pieces should reach the bottom of the hull but as it is, with those horizontal pieces, im using the hull itself for keel strenght, which is not acomplished with the angled-to-bottom pieces.
Total weight of the hull so far: 145g (or 5.11 oz). With the finished deck will be something between 185-200g i think… next week i’ll have time for that…
Cheers

Hi:
i can not see the pictures…just a square with a red X inside.-
Please send some to my email.

Just an update on the fledgling RG-65 Class here in the U.S.
This weekend we registered our 20th. and 21st. AMYA member owned boat - plus we have an additional 7 non-member yachts also registered. This gives us a sufficient number of boats to form either an AMYA Class - or a Class Owners Association with sufficient numbers to ask for AMYA class recognition.
With a current total of 28 boats since early February, the growth of these scratch built development class boats seems to indicate we may have hit a sweet spot relative to cost, free plans, development theory and overall size.
Just a build update - fitting deck, then mast, then mainsail. Jib will be white in color.
that surely looks good Dick!, keep up the good work!
cheers

Great looking boat and graphics Dick. Why not share some of your finishing techniques like (Niel or Nigel ??) from Tronto area did?
I found the RG-65 class rules (Interesting) in Spanish at
www.rg65.com/portal/reglas.php
Using Google Classic on my Palm Pilot Centro phone, I was able to read them in English using the Google Translate website Language Tools. So many fun looking boats, so little time.
With the class just getting going in th USA, why not create some fun racing & excitement buy setting up an Internet Course for the 65 and see how the US guys rank internationly? Good luck on launching your new class and great looking boat.
A friend & I just raced our Footys here in Fenton, Michigan area for the first time yesterday using the Internet course. More in a new thread shortly.
The language obviously depends on your internet domain. Using the same link, I am detected as user from Germany. That means the web site displays partially in German und the rules are displayed in English.
I have copied the text and attached as a word document
