Rigger 3S

[grsboats]

Hi guys

this is my last project: a 3S rigger with low cost electronic's using a 540 car motor,120A esc and 3S 5.0A 45C batteries...you can see the building of the prototype on my page at :http://grsboats.com.br/novosite/?portfolio=grx-fe-3-s .....a fiber version will be availabe soon using a Leopard 3650.

Its maiden voyage at :https://youtu.be/OBev3abCa44 ....she will be our beginners class .
Thanks
Gill

Nice craftsmanship Gill, great to see a FAST affordable power system on the water!
Thanks for sharing!!

[grsboats]

Capnswanny...this will be our entry level boat face turmoil we are facing here downsouth(Brazil).....I only built the hull...electronics was borrowed from fast friends as an attemp to keep r/c boating activities alive as for us with the change in the clouds.i.e. dollar versus real....even cheap hardware can be a problem for many interested guys....hope everything goes true for this part of the world.
Thanks for the kind words.
Gill

I want one! I have a castle 3800kv motor sitting here

[grsboats]

with the release of the fiber version...quite different than this one....I will post it.The Leopard we will use is a 3900kv so your motor will be good too. Thanks Gill

[grsboats]

Ok some time went by but I'm back to this project now with a Leo motor......an important upgrade over the car motor even on 3S.

Hey Gill check out that little red rigger with a little 28mm turnigy motor

[grsboats]

Nice red rigger. in my case the club decided for an entry level boat for novices/beginners to only run 3S boats so the top speed for a heat boat is adequate for these guys.

[grsboats]

New motor Leo 3660 2600KV on 3S.....great handling and speed:https://youtu.be/jTP_fcYAjh0

Wow that thing is a rocket and glued to the water! What does a rigger like this weigh roughly?

[grsboats]

Thanks Mxkid...ready to run about 1,3 kg with a 5.0A bat.In this case I also swapt the previous 120Aesc to a T-180V3....prop is a stock X438!

[kfxguy]

Nice. Runs very smooth and fast in the last video!

[grsboats]

Thanks guys ...takes some time to get things correctly dialed...now its time for the glass molded version.Gill

[grsboats]

After a year testing this boat I decided to go ahead with the fiber version and here is the new look....will be posting pics along the making of the molds.Thanks Gill

[grsboats]

More work done this weekend.

[srislash]

Nice Gill. Keep up the good work.

[Tamelesstgr]

Subscribed!

[grsboats]

Thanks guys from now on things will go quick.Half of the molds ready...tomorrow the schedule is to start the other side if mother nature helps...epoxy really dislikes temps below 17C so I have a heater in the workshop to keep temp controlled.

[kfxguy]

Nice!

[Tamelesstgr]

Gill,

So right now you are making the mold which you will lay the fiberglass in to create the sponsons and main body correct? With those molds you can make as many parts as you want to layup correct?

Ken

[grsboats]

Thanks Travis...this is the only way I,ve learned to make trusty molds...takes time but really pays off.Ken you are correct these molds are for high production,,even not being my case...but I have a dozen hulls to build as we will start this class in our club.actually this boat will be a 4S P limited rigger.here some more progress.

[grsboats]

Molds almost done..need to make another one for the sponsons......

[grsboats]

I'm finally get ready to start some boats...tomorrow will lay up the first one.

[Tamelesstgr]

Gill,

I'm curious, how you assemble the two parts of the boom and the main tub?

Ken

[grsboats]

Ken here's how in all my FE boats: http://grsboats.com.br/novosite/?portfolio=outrigger-grx-fe-2

[tryinotocrash]

Wow thanks for sharing your hard work. That is an outstanding project .
What is the material you poured in the mold as filler??

[grsboats]

Thanks guys yes it is a hard work but pays off....quality in first place to me! Today first boat laid up..Thanks for watching.Gill

[grsboats]

One more step...probably will open the molds tomorrow.

[grsboats]

Parts joined and reinforced with fiberglass ribbon..will pull them out tomorrow.

[grsboats]

Tub is good and strong..sponsons will stay till tomorrow in the molds as they were laid up later and temp here is low (7C)

[grsboats]

Forgot to post the fiber reinforcement in the tub and sponsons.Two 1" fiberribbons plus one 1/2" in the tub and two 1/2"in the sponsons.

[grsboats]

Some work at the shop...need to make six before start building them.We decided to use colored resin to avoid painting but honestly I will paint mine(yellow)..kkk

[grsboats]

Ok boats were laid up and from now on I will post pics of the building process of the yellow boat(mine)...this pic shows two boats ready to be shipped to customers and they will be painted .Gill

[bob horowitz]

Nice work Gill. They look beautiful.

[grsboats]

Thanks Bob..the idea was to produce boats without the need of painting but at the end everyone will paint their boats accordingly to the fiber color..LOL Gill

[grsboats]

Pics of the progress.as this boat uses the same hardware of the proto I will save some snaps of the building.

[grsboats]

some more....Actually this boat is ready to be painted.

[Tamelesstgr]

Top notch Gill! :bowdown:

[grsboats]

Thanks hope to be able to post more progress in a few days as I need to ship some boats to customers.Gill

[grsboats]

Boat is painted and ready to be reassembled....white pearl with blue just to get some contrast.Motor is a Leo X2 3660 2380kv with a T180 V3 esc.

[grsboats]

more pics....carbon fiber turn fin was made in closed molds via resin transfer molds (RTM) and weights only 9 grams.

[grsboats]

The interior of the hull was sanded and received a very thin coat of epoxy resin for finishing.We have four boats ready for some action this weekend so I hope have videos too to be posted.Thanks Gill

[kfxguy]

Very nice!

[Dirk Jan]

Great job on those molds, the rigger looks very neat! Let us know how it performs :)

[grsboats]

Thanks guys...tomorrow is its maiden voyage...will post a video for sure.some more pics showing that using the T180 V3 there's no left room but everything is in place.

[grsboats]

Ok boat went to water with good performance and handling...need some strut adjustments and I'm waiting for my Revo's for more tests.Thanks Gill

[Mike Caruso]

Great work as always and best of luck Gil.

[grsboats]

Thanks Mike.

[grsboats]

mods.

[bob horowitz]

Hi Gil,
Have you given any thought to selling these boats. You've made such beautiful molds, it seems a shame not to share them with your fellow boaters.
Regards,
Bob

[grsboats]

Hi Bob all my models are sold locally not outside due to our very high rated shipping cost but once in a while if a foreign fellow agrees with the shipping cost boats are sent to their destiny....anyway thanks for your compliment.
Cheers
Gill

[bob horowitz]

Gil,
That's too bad. Your boats are really well built and beautiful.
Regards,
Bob

[grsboats]

Thanks fellows.

[martin]

Gill do you find that on riggers in general their is any advantage in speeds with a thinner wedge rudder over a thicker wedge rudder ? . Thinner rudder made from steel to stop it bending, or does a thicker wedge have less drag than a thinner wedge. Thanks Martin.

[SweetAccord]

Your rigger reminds me of the Keps rigger. Small and thin. Love it! I love your builds Gil. I would buy your builds if you offered them like Bob mentioned.

[boredom.is.me]

This is awesome! The glass work is really clean and thorough. I hope I can acquire this level of skill in the future.

[SweetAccord]

It looks like a JAE on steroids! If you made this a kit with hardware, it would sell like hotcakes.

[grsboats]

Thanks a lot fellas..what I would do is move to the north hemisphere where most of my family lives..who knows....Martin I 've been trying all sort of rudder blades for oval and sincerely the difference is not measurable at least on my boats....speedmaster rudders are my first option cause they are thinner than the china ones but again I can't say too much about difference on speeds.About steel blades I tried years ago on my very first Jae and speed was almost the same than with a TFL rudder....in the other hand you will find out a big difference on SAW (+5 mph) with the same set up.Gill

[grsboats]

We are working with our post office to reduce shipping cost for years.......I've heard that with the new politics it can be some light at the end of the tunnel.

[martin]

Gill I assume the +5mph on the saw rigger was with the thinner wedge rudder.

[grsboats]

Martin correct...years ago I used to call Speedmaster to get customized rudder blades for SAW.....thinner but high quality....still have some ones.

What is it that you are doing? What are you selling/offering? What am I missing here?

[grsboats]

We are talking about all models made by me that are sold locally not for the outside due to our high rated shipping taxes.

Ok awesome. What would be the price for example? Do you have a price list just the kit?

[grsboats]

Sweetaccord PM sent.

[Mxkid261]

What's the length? These look so awesome.. I too would be very interested in one I'm dying for a rigger to run 2s and 3s. I'd rather have something like this over a wood kit.

[grsboats]

Mxkid the lenght is 26".......thanks Gill

[ray schrauwen]

Beautiful Gill!

[grsboats]

Thanks Ray!
