It was my favorite board in the right conditions.
I had Stingers, a bonzer (remember those), A G & S Egg, Some Infinity Thrusters shaped By
Steve Boehne. Some boards made from garage shapers. I wish I had A Picture of every board.
I probably have more pics laying around in boxes. I'm not the best at Taking or Keeping Pix, As Dom Reminds me lol.

Cool Thing about the full custom rc boards, is they will surf better or worse in all different conditions
and thats going to be endless possibilities, and a quiver may become a must. Better keep that planer plugged in !

I had thought of a removable component compartment a few years ago, that would allow the same elecs & Drive system
to plug and play in different boards, would be a lot easier.

To All
It would be cool to sea pix of your personal surfboards .

YPC, You love documenting Pictures, Would be great
to see some of your real boards ...

My current 'Quiver'.........the short board I have been riding for almost 20 years now, but I mostly surf the 7ft and long board these days........and they

In my 'one year' of experience rcSurfing - I reckon rather than having a quiver, its more a case of finding what surf 'one' is most likely to surf regularly and work around that to have the ideal board.

Here are a few photos of my boards.
The two yellow long boards
The other long board is a replica of the first surfboard I ever had made new. It was a Balsa Wardy. 50 years of surfing tribute board.
The Yellow MauiRCsurfer was modeled after the gunny yellow longboard.

Status: offline 		My Bondi Surfer Girl has arrived and I have been busy waterproofing it following all the advice on this forum. There sure were a lot of leaks! The best tip was blowing air into the water intake to test where the air bubbles came out! She is all sealed up now.

I am about to take it out for the first run. None of the Radio gear has been changed yet, but I plan on getting some new stuff from somewhere like Hobby King shortly. In the meantime, I have a 7 cell 8.4v 2000mah Nicad and a 7 cell 8.4v 3000mah NiMh. Is it OK to use the 7 cell 8.4v batteries in with the stock standard radio gear. I am pretty sure the standard 7.2v 1800mah that it came with won't last long enough to satisfy me
My understanding is that the motor will spin faster, but everything else should work fine. Is that right?
Is there any harm in running the standard motor that little bit faster? 

Cheers for the help,

Mark

Status: offline 		I rarely chuck stuff away its a problem i have.  I found some pics i took a few years back of a special board i bought mid 80's in almost new condition. Its now in an old board cover stashed in the back of the cave thinkin it might be worth something one day. After the legrope cut through the rail to the plug i was devestated but then just kept riding and fixing for years until it went into storage.

Its a 6'8" Mark Richards twin fin. MR didn't shape it but the pics of it in the condition i was still surfing it besides the blank discoloration are worth a laugh.

Hey surfkiwi.... if you can fit in the 8.4v without it hitting the drive coupling give it a go but i think the extra volts may give bondi girl's electric bits a kick up the ass they may never get over lol.... thinkin if you stay of the full throttle you may get a few runs in but..... you eventually have to go brushless with a better esc and radio anyway so why not see what happens.....

Have fun and all the best, keen to know what happens.... regards bearcave

Thanks for that info. I remember on Radio Waves video that he put a 7 cell battery in his stock Kyosho when doing a speed test against his modified board. I am pretty sure he had also fitted a speed controller. So I guess in order to use the 7 cell I would need to replace the receiver and add a speed controller before I can run a 7 cell? The stock gear doesn't have a speed controller - it is just full throttle or nothing
I don't really want to fry the stock gear just yet because any new radio gear will probably be 3 weeks away. 
 
Has anyone else tried running an 8.4v battery in a stock NQD?
 
Cheers,
 
Mark

My Vote is Larry - Nice Quiver !

To get the most speed and run time on a stock set up,
Go to the highest Ni-mh that will fit.
A six cell would be about 4500 Mah

Not sure if a 7 cell will fit without some cuts.

Status: offline 		Howzit Indatube......MJ did a great color job.....thanks for the 'rating'

When I build a board, it more of a 'TRIP' for me than a chore.......I have a very cool workshop 'at home' with most all I need, from a small lather - band saw -table sanding machines etc etc.....which makes it that much easier.

Time is the 'biggest' resource required when building these amazing little show stoppers.......fortunately, I have some of that at hand every day.

Curls !........with the Kyhoso boards and the like....... don't you think the Nmh batteries played a big part in weighing the board down as well as keeping the speed in perspective. It seems to me that the boards with the Lipo batteries are to light and to fast - hence excessive 'jumping'

As far as i know a brush motor generates the heat from the brushes on the commutator. The coil cooling tube around the can takes some heat away but in the old days they would run brush cooler setups as well.... a brushless motor generates the heat from the windings in the outside of the can hence why the jacket cooling systems work so well...... as far as i know most brush motors were designed for 7.2v and any more volts gives the brushes a good work out/burn out.

Not sure if the receiver will handle the extra volts BUT what if you plug your batt into another thing maybe even a high watt 12v globe for a few minutes then check the volts with a volt meter.... once its down to maybe just under 8v go for it.

Btw i think i saw an old pic of one of kites early boards running a brush setup recently while he was showing something else within the hull.  kite might know powerpark would... hey yeh where is powerpark.

YPC
The lighter weight lipo batts made my production boards way better in all ways, was even able to reduce lead in the nose to get back the desired cg.
Self righting no change..... lighter board with longer runtimes always good.

Status: offline 		Hi guys

One of the main reasons i am interested in rcsurfing again is the most excellent and affordable bang for buck brushless motors and battery technology that is available now to all who have an interest in electric hobbies...... almost thinkin power to weight including batts or fuel is on par with nitro 2stroke.... yes big call and horses for courses but just sayin how good electric stuff is now and will only get better and more affordable.....

Mobile phone's used to have a breifcase size battery when the first appeared but now just get smaller and more powerful every year hey

Hey YPC

I'm not sure if a heavier board would go better or worse just sayin what i see. I think my plastic boards run around 1800gms (4lbs?) and have lead weights inside the hull glued to the bottom shell..... but the foamy kyosho around 1600gms and has no lead ballast in the keel at all but in 3ft and under it goes ok.

When i get more time and the helmetcam happening i will show some vid of foamy gettin some BUT hey you have a foamy kyo atm...... have another look at the 'radio waves' foamy kyo surfers, get that one you have in some 1ft-2ft waves and see what you think. 

Just my thoughts and yes another mindbogglin issue within the rcsurfer trip...... I'm sure in bigger waves with bigger boards and wanting to do more controlled moves changes the whole dynamic of these things but thats why we are all here hey!

Status: offline 		Bearcave........I've absolutely no experience with the Kyhoso and the like....and wont be getting any........just read some time back when most guys started doing the conversion of battery and motor type - hence resulting in being lighter -the added weight seemed to smooth things out.

A lighter hull - going much faster - will be sure to be 'light' on the water. (scitish)....Like a race car with no down force.........

JIMI and others have always advocated that extra weight added to the keel and some inside gave the board a better ride.........I think the average weight was about 2kg or even just over - 2.1kg's.

Its a constant 'ding dong' battle - finding the best relationship between ideal weight and best run times...........the best scenario is to be able to 'add weight' if and when.....depending on conditions.

            Do your self a favor and find a broken surfboard,  cut the nose off, and start shaping ! Nothing beats catching your first wave with a board you made yourself ! It is close to catching your first wave as a kid. To make it  easier check out mauircsurfer how to video. the Bondi surf girl is only going to make you hungry for more speed and durability.

The weight of the Ni-mh does help, and with a 4500 mah the speed is good and long run times.
The kyosho is a lighter hull than the NQD

Hi Guys

Ive been busy working on my other hobby. My saltwater reef tank needed rebuilding. Its all up and running again. Its hard work hunting for corals on craigslist. LOL

Looks like you guys are working hard on new boards. Amazing stuff. Its colder than cold here on the East Coast. My surfer dude sits as a shelf queen for the winter.

Anyone find any good deals on a brushless esc? I think im going to replace mine.

Status: offline 		I have taken the Bondi Surfer girl out a couple of times now. She took a few big waves and spent quite a bit of time on her side. The good thing is the inside of the board has been bone dry every time! 
The battery definitely doesn't last long enough and Need more speed a well. Will be replacing all the rc gear soon now that I know it doesn't leak. 
What does everyone do to help with keeping the board upright. Is the Bondi Girl taller than other surfers. She seems to tip over easily. I suppose more weight in the keel would help. A faster engine would help to keep the nose up as well. 
What mods should be made to the surfer girl. I have seen some people cut her shorter. Others fill her with expanding foam and some just seal her up. What's best?

I can see why this rc surfing is so addictive!

Cheers,

Mark

hey YPC i agree..... but if the waves are small and glassy little lightweight kyo's are good.... a bit bigger the heavier NQD goes better.... none of them like much chop..... adding the extra weight helps a bit but imo just made em more sluggish.

Yeh the kyo is a bit scitish (bit like a cat when its let out of a bag its been in for a while..... lol) your points are valid.... i have changed the tails and played with fins and weighting but seriously think they have reached maximum hull speed and probably maximum everything.
I would never go back to heavy NiMh batts but can't agree more with surfcurls regarding the bigger the mah the longer the run times.

That said.......
I recently purchased mauijohns 'how to' dvd..... been keepin part of an old surfboard for a while now for this trip.... after a first quick dvd look last night I realised how much bigger and different these custom boards are compared to the little ones.
yes have a lot to learn espec with the glassing/shaping trip and a garage full of crap in my way but hope to build one of my own this year..... another reason why ive been watching you and the others for a while taking the rcsurfer into the future....

I only know about the little boards and add my 20c hoping it  helps other enthusiast get more into it....... BUT if i knew back then what i know now i would prob not even bother with all the work involved getting it together but if you have one and keen still rekon they are a cheap starting point to get into the stoke.

just sayin...... bearcave

Yes you can cut Lisa legs shorter she is a bit tall. I stayed away from the foam stuff inside it doesnt work that good and adds extra weight.
I glassed around her leaky joints and drilled holes in her feet so any water in would have a way out BUT she is a basket case and you will eventually divorce her.

Btw i've heard and seen plastic bottles used as dudes. They have no visual connection with reality but work good getting you're hull more sorted!

In a perfect world you will take RC Resinators advice along with mauijohns... heading that way now myself but hey stick with what you have for a while and with minimal expense you will learn lots about you're new addiction.

PS.... as far as i know Kelly Slater grew up East coast USA in the warm but small swell waters. No doubt he was way keen and learnt how to milk everything out of them little waves.... F1 motorcyclists and all i guess start off with no power learn the racecraft and how to get around the tracks with the most efficiency... anyway what i'm sayin is whatever you learn now with practical experience can only help later.

Thinkin you already know that a variable throttle will be better than flat out or nothing hey

Status: offline 		Howzit Bearcave......all good points..........and as you say, the Customs are certainly 'the next step'

I have no doubt that you will be able to put a Custom board together.......in fact.......it is as cheap.( if not cheaper).......most guys are paying around $60 - $100 for a plastic board, which they then gut entirely, only to replace most all the running gear with much the same as one would use in a custom build.

The $60 cost of the board will quite easily cover the cost of a block of foam - glass - resin - sand paper etc .........in my estimate it should cost no more than $40 for the Foam - Resin and Glass.

I reckon, as I have quoted before - if you had to build a board equal in size to the Kyhoso etc - purchasing all the gear from HK - you could get away with $200 for everything.

Shaping and glassing the board is not 'rocket science' .......I have a few formula's which a believe have helped in the design.......but a good eye and some common sense will go a long way. The great thing is- its very cheap to make the actual board - so - like most of us - accept upfront that it is a journey and that the first board will 'not be' the last.

The TRIP is shaping every new board with the anticipated expectation of its performance.................like Resinator expressed........its as exiting as that first wave !

Why not get that garage cleared out.......put the plastic on the shelf........strip that old board you have been storing.........and get down to SHAPING.........

WARNING - ONCE YOU START YOU WILL NOT STOP !!!!

This one is ready for the final 'GLOSS COAT'
