Full Pressure Cutlet

Hi

I just felt i had to start a topic about this. I have downloaded both videos from the website and all I can say is F**KING HELL

Its brilliant. That hawker flew and the selfrighting is comic.

But that leads me to a question. Why use Full Pressure? Surely a 16bar ram with a larger bore would have the same force and use less co2. Admittedly this may not be as fast but look at m2 it uses 100mm bore ram in a heavy. If you put a 100mm bore ram in a feather at 16bar it would knock people all over the place. I am going with 63mm bore 10bar which is think is loads for a thrower.

What do you guys think?
Is full pressure the way to go?
Will i be out of date with a 10bar ram and high flow rate?

If it fills your needs then it is ok you dont have to go the full press way if you do not want to. I still use 16bar in my heavy and i am happy with it long live low press flippers :)

rips low pressure, 10 bar with a big ram ... and ........ need i say more... it speaks for it self :)

Good design is everything. M2 is really really well designed and thought out, and its performance speaks for iteself. Full pressure or low pressure, if youve thought the design out then both should be equally effective (me thinks anyway:-)

However, I rekon if someone were to put the same kind of thought and planning into a FP setup that Paul Cooper put into M2, then wed have something pretty terrifying on our hands. Oh wait- thats gravity :-)

Seriously tho, buffer tanks and big valves for massive flowrate are the way to go. and the more efficient this (reletively) new technology becomes, the better! The future looks good for flippers, and not so great for arenas:-)

I think one reason for using FP is that it may be easier to fit in the the space in a small robot. I think Paul Cooper had this problem with TKM2 and switched from LP to FP.

delta, my new flipper, uses a 63mm bore ram at probably 10bar. its not just a case of power and speed, the shape of the flipper is very important. M2 works well due to its shape also Chaos2. I believe that cutlet has a good shape, this will maximise the power and make sure the other robot doesnt just keep sliping off the end of the flipper.

Mr McDonald Sir...... The answer to your question Why use Full Pressure? is BECAUSE YOU CAN!!!! hahahahahahahahahahah!!!!!

It just had to be done!

Thanks for the compliment, I have had a lot of fun testing and building it. Cant wait to get it in an arena.

Another reason for going that route was that I had tried a compressor powered Cutlet, and a low pressure C02 version. This was the obvious next step.

If you want my honest opinion of how to build the ultimate feather flipper, and keep within the 12Kg weight limit...... I think the way to go is low pressure with a well positioned in-line buffer tank, and very large piping/flow after the buffer all the way to the ram. Actually the preference would be to have no piping after the buffer at all. Just fittings with big holes in, and a large valve.

Cutlet 540 is restricted at the moment as I have not fitted the buffer tank due to the 12Kg weight limit. I may put it in at an event one day just for a laugh to see how many somersaults it can do!

A wise roboteer once said to me

Ed, just because you can do something - doesnt mean you should.

.... he was clearly talking bollocks

Guys as a question which would be cheeper:
1. A full Pressure flipper consisting of: Co2 Tank, Buffertank, Valve, Ram
2. A Low pressure flipper consisting of: C02 Regulator, Buffertank, Valve, Ram

I know the cheepest is good old fasioned air but interms of co2 which is cheeper based on the same things (i.e. same bore ram and valve etc)

Thanks

Depends on quality and wanted force.

Advantage of the LP system. Commercialy availabe parts.Easy to aquire cheap.
Disadvantage. Big and not neccesarely lightweight.More parts involved.

Advantage of a FP system. Simple and can be very small.
Disadvantage, all custom build parts,or expensive parts still to adapt.

If the parameter of thesame bore ram in hold, the FP system will be very expensive and overly powerfull.
