I heard that those cheap little generators work well for what they are. And their pretty cheap. Also heard that the little 2 stroke motors give up after a while, a few people have taken them back under warrenty and the suppliers just replace them, dont bother fixing them. So I'm thinking, there must be a lot of dead generator sets somewhere. The generator side would still be ok, if you had a reliable little 4 stroke you could couple them together. The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |

Hi Everyone well l havent not heard about cheap gen problem as many new or first time buyer brought cheap gen is they must read manual intruction before they start the gen as many of them have no idea how to use correct oil and fuel mix 50:1 as l use Castrol TTS:fully Synthetic 2 stroke oil which run cooler at full load and also they must understand how to use it correcting and understanding " What is wattage mean? " like 850 watt as normal safely use750 watt contuiling all day long without any drama and l have seen simple mind person trying to cook meat on 1500 watt frypan on 850 watt gen by hold on pressing on overload switch. Crazy . Anyway Chinese Gen worth US $38 each however the Buyer must buy approx 300 or full shipping Containter before could land on your front Door (See in Chinese Webs site) Regard ian |

$38 each US$ $99 at Bunnings. It amazes me. How much do ya reckon it cost them to build these things? must be $10 when you consider the freight to oz, and then to the stores, the mark ups etc. Unbelievable. |

Be carefull dwyer, if you go over the max rpm of the F&P smart drive motors you might end up either damaging the rotor or stator. I think the max rpm is 1200rpm? Glenn will know. I would suggest rewinding the armature to suit that sort of application. |

Hi That is correct what you said l do know is very risking to run at high rpm as voltage will be very high and can cause rotor tear apart however l will built full alloy housing over the rotor as l have Tig,Mig MSAW, Oxy cutting and welding equitment ,2 hyd press,Drill brench ,bobo saw, cold drop saw, and also got heaps of air and eletric tools and battery charger run on eletric motor 240 volt run on ford falcon Altnator and that charge 2 battery on old australian made Copan eletric scooter for my Kids to ride around small 5 acre land and road l have be working in metal trades for many years and new lathe is on the way soon regard ian |

Hi chris yes it took me many years to buy tool and equiments my first mig welder l brought was saf 321 amp was brought in 1979 and still going as l have change the wire feeder to CIG and reason it has better 2 gear wire roller while other Saf has one gear and roller causing to much problem on alloy wire but ok on steel but sticking while doing welding lan |

It was probably me who was/is looking for a way to make small wind gennie for a fridge. I also have one of those small gennies you mentioned, and it works quite well. It also has a 12v 8A out which could be useful. The thing is, it takes petrol to run it, so there's a cost PLUS the need to carry fuel. Total package(gen, fuel) is heavy. The weight factor puts me off and theirs an on going running cost. Also, many camp grounds don't allow the use of gennies I only need a constant 5-10A to keep up with my daytime usage, plus enough to keep the charge up. A small VAWT seems to be a viable option. It would be lighter in the first place. If made so it can easily be dismantled/assembled, it would occupy less space when packing 4x4, or ever strapped to roofrack as a complete unit. I've started with a F&P motor to get a working prototype. Once I'm happy with that, I will down-size to a more portable unit. My ideal is a unit that would be no more than a metre high, can be placed on the ground with a few wire stays. Most of my camping is on the beach, so I'm usually going to have fairly clean air at ground level. Greg Greg Just North of Brisbane in Redcliffe OZeTrade.net |

Hi Greg Hmm ? Well l got an idea for you about F&P windmill if is possible you can set up on your roof rack and fold it down when you start move around with your 4x4 and if you camping near the beach it would be lovely as nice breeze blowing from the sea and good luck to you
