Crikey, chocks away!

During bath testing Cyril (as he's been named) was blown overboard and started swimming for the plughole...I never realised quite how much draught the prop would chuck out!

Needless to say I called in the Health and Safety official representative, who duly arrived with clipboard under arm and Blackberry Curve in hand, proceeded to carry out a full Risk Assessment and recommended that Cyril, or to be more precise, his seating arrangement, be fitted with a full PSRS ('personal safety restraint system') for the uninitiated.

Of course I complied instantly, and Cyril is now safely back in his seat, restrained by an ex-Post Office elastic band (which is officially compliant to H&S Rule 23.4, paragraph 12, sub section 6(D), ex-Post Office rubber bands section)

And you said you worry about me sometimes...

Me?

And here he is in all his glory...ladies and gentlemen, boys and girls...say hello to Cyril.

Note the determined look upon his face, those blue eyes, and the delicate way he handles the control lever...what a man!

Oh, and of course the 'personal safety restraint system'...

You could go all the way to protect him.

How about fitting the 'bands' up over his chest to the shoulders.

Looking good though. Excellent find.

Steady Ken, I'd have to call in the H&S again, not to mention the postman...I only had one rubber band!!!

What you need is a Dog. I take mine out for regular walks and have now been banned from picking them up. I have a bin full of em !! Might come in useful one day eh.

"She" says it makes me look a bit destitute and has stopped the practice. A friend of mine used them to make a set of Braces for his pants and when he walks they bob up and down.

I'll have a quiet word with the postie in the morning, Cyril does need a better looking restraint than this. Maybe when I build the safety cage I can incorporate something into it...or maybe I could build him his own 'personal safety protection cage' against marauding alligators or whatever it is these swamp buggies go a'hunting.

I do think a couple of high powered floodlamps mounted somewhere maybe on the to-do list.

Fellow club member and I made an airboat each recently just for fun and you can see how they run here

21" x 5", cheap £7.10 brushless motor 30amp ESC (also cheap!) and a 3 blade pusher prop............great fun!

Cheers,
Ian.

Nice Ian, I like mine...hoping for a proper test run(flight?)on Sunday, so far it's only been in the bath.

The floodlighting problem is sorted....albeit red lights, but they don't frighten 'gators I'm told.

tobyker · « **Reply #86 on:** May 06, 2010, 08:43:17 pm »

Bridkid - they go well - surprised at the dimensions, though - the classic ones seem to be about 2 to 1 length to beam. However yours obviously have no stability problems! Brushless is definitely the way to go.

Bridkid · « **Reply #87 on:** May 08, 2010, 03:01:29 pm »

Doh! Just read my post again and they actually measure 8* x 21" not 5" x 21"! Silly man! They are very light (700 grams all up and ready to go) with rudders made from depron.
Cheers,
Ian.

PS. I did buy the wrong props by mistake (tractor) and no matter which way I tried them they didn't work. Just out of interest.)

Circlip · « **Reply #88 on:** May 09, 2010, 12:05:18 pm »

You gonna paint it in Red Bull colours Rich (Wings??). You could also consider fitting an ejector seat.

Regards Ian.

Just read the second part of your posting Ian. Perviding the straight part of the blade is nearest to the front of the boat and the direction of rotation allows for rotation that the straight edge is leading, then a tractor or "Normal" prop must work??

Patrick Henry · « **Reply #89 on:** May 09, 2010, 12:48:35 pm »

Red Bull? Good lord man, no...it'll be painted in camo colours so as not to frighten them thar gators!!!

Raising the finances to buy another sub...

Hi,
Have you actually tested it yet? I'm just in the process of acquiring the bits to make one

Nige

Patrick Henry · « **Reply #93 on:** May 10, 2010, 05:53:52 pm »

Not on open water Nige, no...it's been bath tested and that was a mistake. Tapped the throttle and it was trying to climb up the end of the bath! It cleared my desk when I tried it in here, it took me ages to find everything again.

seems a shame to sell it before running it at least once, might be wise to fit a prop guard brfore you sell it, or you could find yourself falling foul of the sue it society, or revise your listing to include a disclaimer or the need for one.
What Sub?

PMK · « **Reply #95 on:** May 11, 2010, 12:05:43 pm »

"...or you could find yourself falling foul of the sue it society.."

In which case, U33 should counter-sue the sue'ers for being too stupid in the first place. I mean, what sort of berk would put their hand anywhere near a spinning prop' anyway? (cough, cough).

I'd rather sell it before I run it, just in case I do some damage to it...it frightened the life out of me in the bath, let alone out on the lake!

As PMK rightly says...who'd put their hand in front of a rapidly spinning prop? (You silly, silly boy chap...must have been that last glass of zider)

Well that's what I thought but it didn't..........much cursing and gnashing of teeth!
