Thanks for all the tips guys most appreciated...... especially kite for posting my first go thanks mate.

I live close to flat water but not close to the waves for me can be up to an hour drive (I hear you powerpark)..... just had to post something being so excited getting the camera finally operating.

My mate took a vid of this board a few years back in the local waves when it was running a 7.2v NiMh batt..... It's not much better than my latest first/last attempt but worth a laugh..... going to try and upload it now.

maui john... if i persist with this camera thing I hope to post some wet and grizzly action in the waves soonish... maybe even a roar too but more than likely a stray fish will jump in my mouth..... at least i'll get a free dinner but...... lol

YPC i just did all the antivirus full scan stuff on my computer thinkin there maybe some nasty virul dogs hiding in them trojan horses.... but there were none.
Spent some time re connecting with you tube too...... might need a solicitor to help out on that trip but.

I tried to upload the vid i wanted numerous times but all it did was keep reloading the vid that we all see.......... it is in my "favourites" section on youtube.

Cut and paste without scissors and paper... sounds like swimmin in kelp within a body bag..... Oh well best i try again so having another go at it all soon.

ok after checking out my mates vid it seems to have a very small youtuby thing to paste?..... i'm gunna paste it anyway.... If it doesn't work doesn't matter i cant spend anymore time on this.

If you are still realy bored and want to see very basic surfing of beach slop go to youtube and punch in "rcsurfer cronulla australia" and it should come up its the only one under that name...... it was about 3yr ago my mates channel is 'mome888'

Sorry for all the problems guys.... have to go hunting for food now.... rcsurfing is good but

ORIGINAL: powerpark

Bearcave . Nice video , looks like it can by tilted up and few degrees and it will be right on. It pans good and looks very clear. Nice Job!
Can we get a look at that board? It handels well and its fast! Very cool.

Thanks for the nice comments about the flat water vid guys....and those that saw the old footage on youtube.... InDaTubeLarry, not sure if I was rippin but was certainly punching in the power, much more than is usualy needed in the waves.

As I am unable to glass a glass either (classic surfcurls) but I hope to learn one day so I can eventually build a proper board too.

Anyway one of the biggest probs with these production boards is the "bounceing" they get the faster they go. I didn't want to go down the negative rocker thing so I tried tapeing bits of foam on the tail to try and rectify the bounce without messing up the surfing ability. At one time I had a very long pintail then a square tail. Anyway it got so confusing I settled with a general round tail then painted it so I wouldn't keep changing things and just went surfing. I used epoxy resin with some fiberglass to seal it all after the shape was done.

Here are some old pics of what I did to the tail of this board so you nqd/kyosho guys can get an idea of my trip..... would recomend checking the tails of the pro guys but as i'm not sure if this is that great...... not sure if filling the cutouts was a great idea either... but the experimenting is kinda fun if you have the time.

MJ
Cyber Monday is totally slowing down the Web.

Bear
I found that actually trying to glass wasn't that hard (got some good tips from the best)
It's kinda like painting glue onto cloth. With The UV Resin, it makes it a bit more easy. Dries in 3 minutes !

With The Chine/channels I have, I learned to tack a few spots on the cloth
then dont allow the rez to be at any folds you plan to resin later (like rails, Channels)
If Resin hits those spots, the cloth will harden and not allow the cloth to fold into the curves Properly.
My Fisrt go was OK, and with a few more trys it should be dialied in...

Hey Guys......rcSurfing....just keeps going strong!

Indatube....... awesome photos.......the waves look so chilled......your Maui Surfer looks very comfortable on the face, pulling great cut backs and hanging on the lip !.....love to see some video action...........

Curls.......remember ! when glassing "patience is a virtue" - don't rush it - no second chances..............Glassing the way you are - with the boards foam core profiles being an 'all in one' set up, is very challenging, requiring a few various sections of cloth and overlays......Your 'cut - a - ways' look somewhat 'deeper' than the original kyhoso and as you say can pose a 'glassing problem'.....How many layers of cloth are you applying and what ounce cloth are are you using ?

My latest board has a softer nose shape, still being of the same size and general profile. I have gone with a slightly 'larger' pod- to increase center line lift in the turns - wanting to increase the lean further. I have found that with the smaller Pod, the center line lift in the turn is minimal, leaving all the lean effect to the Bi-Fin.

Like when the board is placed on a solid surface, the raised pod will lift the center line and the board will rest onto one of its rails - I reckon by increasing the potential of the pods ability to lift the center line in the water. more lean will be achieved...........as the CG is shifted onto the turning rail.

An interesting concept now available on brushless motors allowing one to switch between a 'Y' or 'D' configured motor - the exsplanation and numbers help to exsplain th edifference.

Bearcave ..

I checked out the still photos. I have the kyosho board. Mine does bounce. I kinda got used to it. It does bounce more on flat water running wide open. In the surf I use short blasts of throttle up and down the waves. And the bounce is now bad to deal with. I like to drive in the waves in and out.

Its the best race course , always changing and keep you on your toes. LOL. Like Tony the Tiger said. "ITS GRRRRRRR GREAT" Im showing my age. hehehehhehehhe

Thanks for the welcome everyone, there is definetly surf in Oregon, but it is cold and I'm not sure I'm willing to swim/paddle for a retrieve. That said I've been doing a little recon for possible spots and found a few that look promising.

Finalized (I hope) the build plan and have ordered parts. They are starting to trickle in.
Kyosho Lisa Build:
Stock hull, shaft rudder and figure.
Leopard 3660 3060kv 2 pole, Leopard 36x50 cooling jacket
Swordfish 90a esc
Duratrax (futaba) waterproof servo
Turnigy nano-tech a-spec lipo, 3s 4500mah 65c
FrSky tfr4 reciever, compatible with my futaba 4PKS

Worked on the water pick up/outlets today, drilled them @ 3/16th" (5mm) and braised some brass tube to 90* fittings.
Firts time braising, and the micro torch that didn't solder well kicked butt at sweating the fittings!
Planning on 2 seperate cooling systems, 1 each for the esc and motor.

Pics to follow, my hope is to have it together and flatwater tested by my birthday, Dec 15th.
Thanks again for all the knowledge and stoke shared here!
Aloha 'oe-Billybongo

Great Pix !

YPC
The boards glassed by the crew are 2 layers of 6 oz.
The one pictured is my test project. I'm doing (1) layer 4oz then (1) layer 6 oz.
My real board has 1 layer of 4 oz & 1 layer 6 oz for (bottom) & 2 - 6 oz on the deck, so it got me thinking 12 oz of glass may not be needed
so I'm gonna test 10 oz and maybe 8 oz.

Hey Curls !.....

6 ounce works well for me....I use 2 main layers on either side of the board.

To ensure that the hull is strong enough when I hollow out all the foam to create the housing. I also add a 3rd layer inside the housing area base once it is created, as I build up the housing wall.

To ensure that the deck is strong enough around the housing/lid flange to support the pressure push down of the lid seal, whilst helping better keep the bolts in place.

I also place a small patch either side of the board, in the area of the rudder pivot tube, to ensure that their is extra strength to withstand the leverage.

Relating full scale board strength to our rcboards - besides the strength of a stringer, the weak part of our boards is the area of the hull where the housing is, this needs strength to prevent flexing, as it carries the righting weight, as well as the motor , battery etc which all told id the bulk weight of the board.

The speed of our board is also quite considerable increasing impact effect and if you equate the weight of a board to the surface area you will find that a full scale board could have less load bearing weight than a rcboard in relation to total surface area.

I have noticed that the board takes quite a 'knock' in the water when hitting khelp heads and the like....I have one or two good dings to show for it. Even a third layer of cloth would be good on the hull side.

YPC....

The idea of the extended prop shaft was to get the bite of the prop deeper and furthar back in the water.... I have bought lots of stuff from 'offshore' and they had these generic shafts that took threaded props and i just bought some (and some props) then cut em long and short and tried em out.... remember the nqd has a rather angled driveline..... and lookin at surfcurls latest version I think I'm seeeing a more flatter drive angle which can only be good in all ways.

Atm I still have no idea wether the prop's position aft or fwd makes any diff but.

Regarding the thin swept back fin all i can say is that when i got into this pastime many years ago I did enjoy the Ed Deitrich/Bad Billy way of doing things.
If you look closely at a Bad Billy single fin you will see it generates some downforce.... bit like a bi-fin with tabs....maybe not so much but it is there.

Anyway the swept back fin in the pics gave me a more loose and less direct steering action especially at speed on a wave face...everything changes when you are goin fast..... actually I might run it again and see how it goes..... maybe some more vision of another first go at the boat ramp with an old school fin....
Obviously not as exciting as in the waves but hopefully there will be more V8 boats charging around for those most enjoyable musical sound effects

BillyBongo.... all looking good for a nice birthday hope all goes well... if not welcome to the addiction of making it better (remember its neverending lol)

Powerpark.... I played with my Kyosho along the the lines of the "David Reece Radio Waves" vid.... my take was a bit different but if I get some time may take some pics of what i did to that tail.... haha maybe even a first go at the boat ramp with a Kyosho as well.

InDaTubeLarry..... nice pics.... reckon you are already there you just need a video man or a helmet cam to show us more...

BTW longitudinal centre of gravity makes a big difference too..... and at the end of the day these are just my opinions so don't read too much into them.

billybongo... I have given up on the solid shaft couplings..... most guys are running flexy shafts these days but i'm yet to get there.

Karl H2o and YPC seem to have the shaft system worked out well and i hope to modify my boards that way eventually too but have noticed Kite has a 'splash gaurd" and YPC is running one like i do too to stop the water/grease/oil leaking up your shaft spraying everywhere.

My flexible drive coupling is a Graupner uni joint that works good on rc cars. It's not stainless and needs oil now and then and even though the motor needs to be mounted more fwd to suit (helping cg without added lead) and the flexing angles are not exactly right it works so much better than a solid coupler.

I posted these pics a while back but what the hell seein as the cyber gods are allowing me to post pics here are they are again..... maui john I think uncyber monday may have passed.... not game to have a go at postin anything vid wise myself but the latest from Hawaii is always welcome...
