Had 'another' sweet session this afternoon ....
It's amazing what 20 minutes of rc Surfing can do for the mind - body and soul ...
recommended daily !

Hollowing the POD out
Cloth is left extended beyond the housing wall to be trimmed only once the white flow coat has been applied and cured to prevent any mess.
Board is held up to light to mark the POD's profile.
Cut out and hollow as with the housing.
remove all foam and wipe out with acetone in preparation for white flow coat.
Drive shaft housing area is cleaned out entirely of foam as it will be filed with epoxy when fitting the drive shaft housing.
Tape up drive shaft housing exit to avoid ant spillage.
Liberal coat of white flow coat ( gel coat with wax mixed in it) seals and strengthens the housing area.
Leave overnight to cure 100% before trimming down the exess cloth extending beyond the housing walls.

Molding the Housing hatch cover
I use a 10mm sheet of glass to ensure a flat surface around the housing flange - then have a raised insert to accommodate a 4s battery - board being 30mm's thick.
If the entire housing area of the board was made 'thicker' to accommodate the 4s battery- it would increase the overall 'volume' of the board - requiring more weight to right it. - hence the minimum volume area is introduced....
Surface is prepared with a few layers of release wax and a PVA release agent...left to dry 100%
Start with a thin layer of coloured Gel coat - left to cure touch dry - then the first couple of woven cloth layers
are applied with the colour pigment mixed into the laminating resin to ensure the depth of colour. The aim is to
create a waxed deck type of look. (fused).so.. the balance of the laminated layers will be applied with clear laminating
resin , with the decals laid in....
For those who are interested in 'the logo's significance?'....it's a pretty standard recycle logo - which I thought would be
appropriate for a Bro board - You get to use it 'Over and Over and Over again".......LOL....
Rough cut to size and shape - to be accurately within the deflection rim of the board.
Recess in the hatch cover is to accommodate the 4s battery pack.

...it dawned on me today ! that whilst I'm out having my afternoon fix / workout/ session - surf permitting ! - some good folk are stuck in the traffic - patiently waiting to get home...
....couldn't do it
Nick did some 'deep sea fishing'.....

Deflection Rim
Sand down the rough extended housing wall side cloth
Mark out the perimeter of the hatch cover.
Fit the Deflection rim ( high density foam to be resin coated)
Deflects water from impacting between the seal and deck.
Fine fit the hatch cover to suite the deflection rim.
Has a textured finish to emulate the surfboard texture decks.
Whalla ! hatch cover / deflection rim fitted....phew !....

Rudder Tube installation.
Before installing the rudder tube - a first coat of colour resin over the Deflection Rim. Its important to seal over the edge where the deck flange meets with the top of the housing wall....to be sanded down once cured - to receive a second coat.
The rudder tube needs to be secured very well ! The rudder takes so much impact - driving the boards direction and
enduring impact from landing on the sand - hitting objects in the water - landing big airs etc...etc..you dont want it coming lose - EVER !
Firstly - you need to position the tube in an oversize hole to ensure that the epoxy flows completely around the tube in its full length, ensuring a good bond
/ key between the tube and the foam.
Secondly - the epoxy needs to flow well around the tube and the fibre- glass surface - keying the brass tube to the fibre -glass - a small mound of epoxy around the
brass tube is good for added strength.
Thirdly - leave the tube extended whilst applying seal and gloss coats - as each coat built up around the tube will add to it overall strength.
It's been a good day in the workshop -
- Unfortunately the surf is blown out this afternoon ..

Second Filler Coat / rudder post
Once the epoxy, bonding the rudder tube, has cured - another filler coat of pigmented resin is applied to the board to fill in any small blemishes..pin holes.
.....special care is taken to pool the resin around the protruding rudder tube... to add further strength....
As with the deck - the hull / bottom of the board receives another coloured filler coat.
What is critical is to ensure that the board is level so that the filler coat flows equally and true to the boards surface.
Rudder tube filler coat pooled around the rudder tube for strength.
Once cured - light sand - then the decals are applied covered by a clear sanding coat.

Always great to receive a note of how things are going........thanks Geoff..
Hi Dominic
Been enjoying watching your vids and board updates on rc universe
I was driving home on Sunday afternoon with the family after enjoying Bro and thought how great it must be for you knowing your boards are being used all over the world including kettering uk!!!!!!!!!! Keep up the great work
Bro sure is getting some comments

Monday Arvi session - fun 2ft face - ( Amps + Time) = STOKE
Some rc Surfers seem stuck on surfing 'Big Surf only'- lol - bit of an irony .. Surfing 1ft face surf can be as much fun as taking on some 6ft face ....there is always some STOKE to be had......in this video I ran a single pack, left over from the previous days session - had 20 odd minutes on my hands between family sport activities - less than average surf conditions - had a few great waves to savour ..Airs - Cut backs - Bottom turns Rodeo's - Off the lips'- Tail snaps - down the line pumps ....the stuff surfing is all about....

Creating the Bro Dude !
Besides the obvious floatation requirement the rc Surfer dude needs, for the purpose of self righting - there are a number of other critical factors that need to be considered, to create a lasting - well performance capable - rc surfer dude....as important as every other aspect of the board.
Most all rc surfer dudes are made of rigid foam / covered with light glass fibre / wetted out with either polyester or epoxy resin....resulting in a 'rigid' figure that has absolutely no flex ....to absorb any impact. ... many breaking rather easily and regularly, mostly at the head and arms, when experiencing any severe impact.....limiting the performance level and reliability of the board.
If more required strength is to be built into the figure, by way of adding more layers of cloth /resin etc .... the figure simply becomes 'heavier' requiring more counter weight to be added to the low CG point of the board, making the overall board heavier..(less efficient)....as well as..due to the added weight of the surfer dude... producing more outward centrifugal forces in the sharp turns...upsetting the balance of the boards performance......resulting in the outer rail tripping/digging.....board flapping over.
The goal is to create a surfer dude that is: very durable - has sufficient floatation - flexibility to absorb impact - as light as possible to minimise counter weight and outward centrifugal forces.....once those factors are covered.....the ascetics can be dialled in to personal preference.
IMO - some make far more of the detailed ascetics of the surfer dude, than what it is worth - ( some call it playing with dolls)- at 30 plus yards in the surf, all one is left 'seaing' is the dimensional silhouette of the surfer dude. The bigger the stance of the surfer dude, the better the presence of the surfer dude, at a distance. Bright colours and black work well against the colour of the ocean and white water..to be able to quickly identify the surfer dude.
The YPC Bro surfer dude - is unique- has come a long way since its initial design - well proving to be : very durable - buoyant - flexible - lightweight - and - in the eyes of the beholder - looks rather realistic in the surf...
Bro's structural make up consists of a moulded flexible 3D stanced silhouette core (made up of fibre glass and carbon fibre / wetted out with epoxy) - then laminated with closed cell neoprene on either side - its head is moulded using 2 part polyester closed cell foam ( very light 8 grams)
The complete finished Bro Surfer Dude product - including an authentic Lycra rash vest - weighs in around 140 grams...
flexible 3D silhouette core laid up and curing in the mould - to be trimmed to outline once cured.
Carbon fibre layers for added strength in strategic areas.

Once cured - the moulded figure is trimmed to the accurate profile
https://www.youtube.com/watch?v=2jAXmxD8TAI Establishing the figures position is critical for balance and self righting rotation.
https://www.youtube.com/watch?v=aysHKDTcUxw or your dude will have to look something like this
The carbon fibre bonding foot pads are moulded to the figure and to the hatch cover at the same time, to ensure a snug profile fit.

,,the surf had dropped off a touch - but-,,there were a few young local beach kids who had never seen an rc Surfer before and were just so enthralled with it... I so enjoyed the depth and excitement in their laughter..made the session so worth while....SHARING THE STOKE !..

S/S studs bonded in place - knurled nuts are great ascetically - and - prevent one from over torquing the nuts
which can rupture the studs bond into the foam.
If this was an actual surf board we would be just about ready to 'surf it'....still have a few steps to go !

what's SUP Bro
The SUP (added paddle) idea has been brewing for some time - on several occasions whilst surfing Bro, some one would suggest the SUP concept...reinforced by Gary and Ivan...SA.SUP Pro's....a novel idea...
In designing the paddle add on - I wanted to design a paddle that could simply be attached / removed to/from the existing Bro figure - be light - durable - be able rotate to minimize impact - have travel within its mounts ( ie not rigidly mounted) - look authentic - not protrude beyond the rails br streamlined in the forward travel...
For most of the list above, I have been able to tick the boxes....
The paddle is simply held in place by a small nylock s/s nut ( fitted into a servo disc) which is screwed
onto a 3mm threaded stud. protruding from the paddle shaft end....Loosen the disc - slide the shaft out.
The paddle shaft fits through the Bro figures right hand and through a
Velcro strap, which is bound around the left wrist, under the sleeve.
The paddle feels very secure - having the ability to rotate and travel on impact
as well as Bro's figure being flexible to absorb the impact...I reckon it should hold
up pretty well.....
Its going to be interesting to see if the paddle adds any further 'movement' ( spin)
to the Rodeo's etc...
