Decided to make a separate thread for SloMo, as it was getting very complicated!

Great news, chaps!

SloMo now running with two brushless motors!

Had a faulty ESC all along!

Found out by fitting the Ellie ESC and it worked first time!

And to make really sure, we fitted the faulty ESC in Ellie and it didn't work…..As expected

Next test without the sponsons, will be Saturday morning…..Can't wait!

Pleased as Punch!……..Bob

Hi Bob,

I hate to say "we told you so", but…

Good to hear you have that issue resolved, I can't wait to see SLO-MO stop living up to its name.

I think it is a good decision to leave the sponsons off, with these two brushless babies in control this boat should go like hell!

Make sure you have someone shoot a video too.

I know you suspected a faulty ESC, Dave…..I just wouldn't give up, because at that time, I was fully embroiled in trying to follow the set up instructions

The main reason why the faulty Esc was not spotted earlier, was that is behaved as a working one!

My pal Duckie happened to call in today and he couldn't understand why the faulty unit wouldn't work in the Ellie cruiser…..As it emitted the correct startup bleep code

Anyway, I'll hold my hands up and eat some more chuckle egg?

One good result from all this, is that, I've learned such a lot, that I'll go for brushless every time!

Perhaps it can still be saved?….It may not have been set up properly at the manufacture stage?

Will try and phone them tomorrow

It's probably a blown end stage… Y'know, there's three phases, if the FET's of one of the phases is toast the ESC will beep just fine but when you try to rev it, you get a whole lot of stuttering, at best…

I don't know how this ESC is built, but most ESC's I had my hands on were either not repairable (covered with resin) or not worth the hassle.

Sailed SloMo2 this morning and it sailed beautifully!…..As we all expected?

No sponsons and twin brushless motors on song!

Frightfully fast and fantastmigorical!

Almost too fast at times, for us two old wrinklies, as we had difficulity in seeing far enough ahead as we charged about the lake……into the path of the buoys and wildlife!

The battery lasted for about 20 minutes….Not bad?

Here are a few pix…………….. Duckie`s video will follow shortly…

I like the way, SloMo leans into the turns

Rear view…

Almost airbourne?……

Getting serious now

Just admiring the view

Waiting for the off

Bob

Well done Bob ,that looks rapid .Now maybe we will believe in brushless motors

Bob. At last. A Slo-Mo that goes fast !! Well done (eventually). Great colour scheme.

Still think the rear fin is too small but that`s just my personal taste. Not quite airborne but getting there!

Good job.

Hi Bob

Now that is what we were looking for. Nice bit of air under the bow, when on the plane. Brushless is the way forward for sure.

It looks marvellous, Bob, well done, and I love the colour scheme. I'll bet you frightened the daylights out of the wildlife

Many thanks for all your kind comments

It's been an uphill battle at times, but was worth it

The faulty ESC was undetectable in the early stages of setting up and it's probably a good idea to standardise on one make motor combination and if possible, have a few in stock

I can really recommend going the brushless route they are so pleasant to work with, they are so smooth and quiet at low revs

A few problems in the early stages is a good way of getting to understand the workings of these new motors and removes the nail biting mystery of it all!

Hi Bob,

Looking good on the quick dashes!

Now just train the driver to open up the throttle more; a racing boat like this should be dashing around like mad.

Can you just remind me what the power train is as it takes forever to trawl back for the details

Thanks Diede

Just thinking of having "L" Plates fore and aft……Just for a bit of a laugh!

Hello Mike

It is a bit difficult back tracking, but if you do and find the link, it`s worth keeping handy, as the link with all the info on is not on the net anymore for some reason

Motor….Turnigy D3536/6….1250 KV

ESC……Car-45A

You will need to find the link for the prop and other stuff

All the best

Bob

ps……Found it!

All of this dashing about has made me think about designing a 'stripped down' version of the Ellie boat.

At the moment its just a notion to create an open cockpit, vintage style stepped hull speed boat with a lightweight frame and three of these brushless thingies to push it along.

Based upon Slo Mo2s performance a lighter and more powerful hydroplane version should almost fly.

All I need is a willing volunteer to build and sail it.

Hi chaps

Pleased to report that SloMo2 was awarded 2nd place at last nights AGM……Thanks fellas

The snag is,…….Due to the ghastly weather I opted not to attend…..Hence no photograph

But, not to worry……Pal Ducky has taken a few pix, knowing that we can Photo Shop the results

Photo later amended with the face correction!

With a bigger trophy……Just for a bit of fun!

Hoping to sail SloMo 2 and Lady Joyce today

Should be an interesting comparison

Bob. Its a bit ironic that SloMo2 , based on a cabin cruiser, is more successful than your orig boat based on a super duper hi-tec hull design !

Should be interesting, as you say, sailing both together,

Well done on award; No annual awards at ouir pond, perhaps I should instigate some…

not sure what categories we could use.. biggest squirter, best use of cheap but strong man-made board, best wild beast, craft most attractive to young mums, best Top gear vehicle and so on…
