WANTED 1/16, or larger RC Tank

[Trevor HollowayParticipant @trevorholloway99134]

With all this lack of progress, chances are it will never not get built !

[Paul TParticipant @pault84577]

Hi Trevor

I this isn't the current not project what am I currently doing, or not doing apart from bantering about nothing…..my head hurts now with all of this non creative un discussion.

Paul

[ashley needhamParticipant @ashleyneedham69188]

I would not look waste time looking up motors such as this.

But at 6s

I dont suppose 4Kw would be enough anyway for a non project

Ashley

Trevor..nice one, not.

[Paul TParticipant @pault84577]

Ashley

How about two of these.

Turnigy Rotomax 150cc (petrol engine equivalent) 9800w, 51volts, 5.2amps Lipo 14s (14 cell) 2.5kg…..price don't ask

I have also been researching PolyZion batteries.

Paul

[Dave MilbournParticipant @davemilbourn48782]

You cannot be serious…..can you?

9800w = about 13.6HP = 192A @ 51v. That's about a one and a half minute ride from 5.2AH cells. Helluva ride, mind you.

How much is it to hire Coniston Water?

[ashley needhamParticipant @ashleyneedham69188]

No, he is joking…..

[Paul TParticipant @pault84577]

Hi Dave

The reviews are fairly good (but they would be) they are very expensive units and that's before buying the batteries and ESCs.

These are the specs.
Battery: 14 Cell / 51.8V
RPM: 150kv
Max current: 190A
Watts: 9800w
No load current: 51.8V/5.2A
Internal resistance: 0.011 ohm
Weight: 2530g
Diameter of shaft: 10mm
Winding: 8T
Stator Pole: 24
Motor Pole: 20
Stator Diameter: 101
Lamination Tickness: 0.2mm
Suggested ESC: 250A 14S Compatible

No need to rent Coniston as there is a nice straight bit of Bridgewater Canal near me.

Ashley

When did I last joke about modelling?

I am looking for an excuse to build the non project and these beasts would make the project unbeatable (and even set a record)

Paul

You will have calculated the price of two of these plus the batteries . I make it around £1100. I have no idea how much a 250A ESC would cost (or rather two of them) – and then there's the chargers and props – but you strike me as a man with a touch more sense than money.

You don't need an excuse – you need a sponsor. How about scaling it down a bit? If you're not going to build it then the size really doesn't matter; you pay for it with imaginary money.

Hi Paul

I can feel a RIGSBY coming on!!! Myyyyy Goddd! he's going to launch Bob down the Bridgewater canal in his bath chair, 200plus mph, that should blow his hat off!!!!!!!!

I think it's about time the title of this thread was changed to reflect its new content. Negatives should be avoided to prevent even further confusion.
Might I suggest "nom may'Duj"?

You may have just solved the ballast problem as I needed something strapped to the bow to balance the hull.

Dave

I'm still looking for a tank but it might not be worth starting a new thread if I don't build the project.

Paul

[Paul TParticipant @pault84577]

Hello Kevin

I came across a great deal on sheets of 4ft x 4ft aircraft grade birch plywood so I bought some for this winters build.

But its not for the non project.

Paul

[Paul TParticipant @pault84577]

Dear Kevin

Ashley has started me thinking with he recent comments about pop pop engines and I am now seriously considering how to use a pulse jet to drive a model boat.

Mounting the engine on top of the boat in a similar way as the V1 pulse jets would keep the intake and exhaust out of the spray and allow the jet to achieve quite high speed.

Now all I need is a four mile long lake and someone daft brave enough to build and sail it.

Paul

But it isn't a project so this is all hypothetical

[Trevor HollowayParticipant @trevorholloway99134]

There was a pulse jet car made on Scrapheap Challenge once.

It went well and sounded great.

[Paul TParticipant @pault84577]

Hi Trevor

I saw that edition of scrapheap and despite the noise the pulse jet ran very well. I am thinking of using a Propane/Butane mix as the fuel.

Paul

[Trevor HollowayParticipant @trevorholloway99134]

Surely there is enough hot air on this thread to power anything !

[Paul TParticipant @pault84577]

If only we could capture all of the hot air that is spouted here…………..no more fossil fuels but it might not help with global warming. lol

[ashley needhamParticipant @ashleyneedham69188]

I dont think it is that difficult (hows that for a THROWAWAY REMARK !!!)…the theory is very easy of course..however both jets in the scrappy challenge ran red+ hot…would be v difficult on a smaller scale to insulate that sort of heat.

How big can you make pop-pop engines???

Ashley

[mike farrellParticipant @mikefarrell21522]

Question please ,Is Paul building a model rocket to send a scale model boat to the Man in the Moon to get him to see how it will react without all that hot air going the rounds ,Well its just a thoughtMichael

[Colin BishopModerator @colinbishop34627]

Pop Pop engines are very interesting and there have been various articles over the years on developing them to extract the maximum power, sometimes by employing several in parallel.

Colin

[ashley needhamParticipant @ashleyneedham69188]

Mike. Paul is not building anything, as he keeps on saying….

Ashley

[Paul TParticipant @pault84577]

Hi Kevin

The not a project might be called Banshee and as the name suggests it could be a screaming demon but don't get excited as it wont be built so it cant be shown at Haydock.

Paul

[Paul TParticipant @pault84577]

Hello Kevin

I have been playing with mixing brushless motors, hovercraft and BB firing tanks

Its not the not project but it isn't a project.

Paul

[mike farrellParticipant @mikefarrell21522]

Hi Paul Is the not a tank a Turbocad lesson in simplistic design as my mind is in complete turmoil trying to get to grips to this not a project Michael

[Trevor HollowayParticipant @trevorholloway99134]

It would be "interesting" to see the craft in reverse when firing – however we will not get that pleasure.
