  1. Thanks Skippy, Progress has been sidelined by events in Mallacoota these last few days. Might be a few weeks before I can progress this project...Hope you have a good New Year, Peter
  2. Thanks to all for such a useful discussion, lots of ideas, many new to me. From all these inputs I’ve decided what I’ll do & ordered the bits & pieces. When its all delivered & assembled into a working system I’ll post a video & links. Given the holiday period & delivery delays, it’ll probably be a couple of weeks. Then I’ll welcome comment on what I haven’t thought of, or fundamental flaws in my thought processes. Thanks again to all, Peter
  3. Prwood, thanks for that info yenn - the rope’s a good idea I’ve not seen used... thanks
  4. Prwood, do you have brand name for your yellow screw? What’s the diff between your type & the Screw It brand?
  5. I've read the forums about the choices available when choosing a Tie Down system. However, there doesn’t seem much new added to these forums in the last two years. Anybody found anything that really works? Links to new or improved systems eagerly sought. I’m also interested in opinions of rope type vs ratchet webbing strap types.....Thanks
  6. onetrack, thanks for your thoughts. I think it could be argued that car static straps don't work precisely because they are not truly grounded. Just as a post in a hanger is unlikely to represent true ground, a car static strap touching the ground is very unlikely to be truly grounded. Which is why you get zapped, your body is doing a better job of discharging the static built up than the strap. Your comment about mobile phones I agree with. The RF output of a mobile phone is miniscule, the potential energy in a static discharge is hugh by comparison. The fuel companies are covering their asses with their insurers. I'm over zealous because I have been very close to an aircraft oxygen refilling incident, where the rules were short cut, blew the nose off the aircraft & killed someone. The link you provided to liquip victoria was really useful. I hadn't contacted them, they turned out to be really responsive & helpful, unlike some others. Must be the onset of Xmas when sales depts don't return calls. Thanks for you contribution, Peter
  7. Skippy, I'm relying on my RAAF training of 50 years ago for my static design. Your tank may be sitting on the ground, the aircraft is on rubber tyres. Just because something is sitting on the ground, doesn't mean it's at the same electrical potential as something nearby. A hangar or other building frame may not be providing you with a good earth. Best to get an electrical ground stake, about 3 meters long, made of copper, driven into the wettest patch of ground around your hanger. (Most commercial static earthing systems specify a maximum resistance between the aircraft fuel tank earth point & final earth point as no more than 10 ohms). From there a 2mm or so, galvanised or SS multi strand wire, fitted with a strong clamp is run to your exhaust pipe. The line to the aircraft may have a Y fitting on it so that the second arm of the Y is clamped to the discharge tank & pump. If you don't have a Y type, a second wire is clamped to the exhaust, the other end to the discharge vessel & pump. Finally a third wire is clamped to the discharge vessel /pump & clamped to an earthing tag at the fuel filler on the aircraft. If you really want to complete the job, the refueller wears a wrist strap connected to any of the points being used. I haven't seen any LSA type aircraft that have earthing tags at the tank fill holes, so the best you can do in those circumstance is to ensure the filling hose is touching the neck of the tank before you start filling. You can buy filler hose that is constructed with some carbon in it, so that it has some degree of conductivity. If you wonder why I'm a lot anal about static, ask your local Rural Fire Brigade to run a community demo. Pour a 20 litre can of petrol on the ground & ignite, don't be standing any closer than 50 metres when they do it! An initial setup of fencing wire or building construction wire may do the job, however the constant movement will eventually cause issues. I think you'll find commercial fuelling setups, such as at airports, have to run a series of tests on the static earthing setup every six months. You'll remember that my aircraft is a 'plastic' plane, so there is little likelihood of an electrical earth connection between the exhaust pipe & the tank filling point, even more reason to be careful. I'm still searching for a commercial retractable reel setup at a reasonable price, when I find one (if I do) I'll let you know. Please feel free to poke holes in my thinking! Peter
  8. Hi, I did occur to me that a rigid intake pipe might work better on a bladder. The company can supply a range of different length intake pipes, all can be fitted with a decent filter at the bottom. It's a trade off, as you've mentioned. Keeping the pipe in the tank, supporting the bladder & winding the pump, all at the same time. I'll report back when I've tried it out in the various configurations. My next issue is trying to find some decent static charge discharge cable reels, the price of these is shocking. I'm thinking of exploring the use of electric fencing reels, the wire & tape wind out reels that horse owners use for temporary fencing. I'll have to look into their electrical properties, they may have much too high resistance. If you happen to know of a supplier, I'd appreciate a lead, regards, Peter
  9. The USA site contains more info than the Oz site, go to www.flofast.com. The original design was for the racing car world. The delivery hose is fitted with a clamp that allegedly holds the delivery pipe in position. The pump fits into a container, that electrically bonds the pump to the container. I'm hoping that I can mod the pump, if needed, to change the input pipe to a flex pipe for pumping out of flexible bladders. When I get to use it, I'll let the world know if it works or not. Thanks for sharing your ideas Skippy, Peter
  10. Thanks for all the input, some innovative ideas. I've decided to go with a commercial product, www.flofast.com.au. Hand operated, high volume pump. Different length intake legs available, pump disassembles into small components. I've found it difficult to source reels of static earthing straps, commercial ones range $800-1500 that I've found, I'll have to make some up. As I have a 'plastic' plane I'm really concerned with static, so I'm going to connect hanger (or similar) to engine, engine to pump (it has a earth point on it), pump to fuel tank inlet. I'll post on how it works, or not, in the new year.
  11. This question has been discussed before, I wanted some more up to date info. My age & fitness precludes climbing a ladder with either a 10 or 20 litre container. I need to carry collapsible plastic fuel bladders (20 litres each) & refuel (Mogas 95-98) from them in generally somewhat remote locations. The aircraft is an LSA, high wing, combination of carbon & GRP. What is available in well earthed electric fuel pump or, again, well earthed manual pump. Ideally I'd like to use something like a Mr Funnel as the final stage, however a built in filter, of similar capability would be easier to use. The aircraft capacity is 110 litres, so I'm unlikely to be refilling more than 60 litres at a time, 30 litres per wing. I've looked at Facet, McNaught, Polarn, FillRite, Flo Fast & Jroc. Some of these are only suitable for pumping from a 200 litre drum, some are OK for jerry cans, very few are portable in that they will fit in the small cargo area in an LSA. Many don't seem to adequately address my concerns about earthing, particularly with a plastic plane. Any ideas or experience please?
  12. Having only two on the ACT list caused me to put out the question on this site. I've since found an outfit in Yass, FPV, & would welcome any comment about them.
  13. Thanks for the link. it leads to info about a CASA app that informs about flying zones for different classes of drones. Handy app to have, I didn't know that it existed until your link. There is an operator in Canberra called Wing, which is developing a food delivery service. Still haven't found a training company with a good reputation.
  14. I want to get an RePL certificate to fly a drone under 7Kg. I have an RPL & understand that I just need to do a days practical training, rather than the whole course. Doing the research, it seems a lot of people have jumped onto the drone training bandwagon. Has anyone had a good experience they can point me to? Ideal area for me would be Canberra, then Melbourne or anywhere in between.
  15. High wing is good for old age & bad back, avoiding stumps & fence posts, reducing sunburn. Really lousy for refuelling. Fuel delivery & valving arrangements vary widely. specially in the kit built world.
