    The Savannah S POH says it may be flown with one or both doors off. That side-slip should be avoided if only one door off. And that drag will be increased, particularly at high A of A.

    That's a really enjoyable interview......)

    Marty, I'd settle for once......)

    I wonder if the problem could be inadequate strength/bracing in the float? We once had a f/glass canadian canoe. Heading for home in failing weather after a week on a big lake, I accepted a tow from a power boat. While there was little in the canoe (just me), when the canoe got onto the wave from the boat, the bottom went flat then dinged in sharply. And while it didn't break or tear, as I recall there were stress marks where this may have happened before.

    Nice looking job, Marty! Another option is to have the the LE sitting in a sling, webbing or I used a strip of carpet, attached at a centre high point of the frame then passing down and under the LE, with the other end attached at a raised point over where your casters are. So the wing is sitting in a pair of slings, which conform to the shape of the LE, and are not resting on anything hard or solid. I copied mine from a pic I saw somewhere, passed it to another builder who has beefed it up and added wheels, it has now passed to a third builder...........)

    Depends what you are viewing on Flying Dog: On my laptop/PC it's a blue Following button at the top RH corner of the thread. Click on that and you can unfollow the thread.

    Danny, you may want to check the current output of that USB port: I have seen an aircraft equipped with them initially, but subsequently replaced with good quality conventional USB charging ports. I can only assume either that the output was inadequate for whatever they were driving (tablet?), or that they were electrically noisy.

    BTW, there was early first person footage of parachuting into trees. Probably deliberately, as it would have have taken some effort back then to mount the camera gear. This was round canopy stuff, and shortly after entering the trees it looked like the jumper fell very sharply. I think what can happen is that if the jumper/payload/aircraft momentarily snags in parts of the tree, the canopy above continues descending or deflating. Then when the j/p/a unsnags and falls it is now no longer supported by the canopy, so can fall at a much higher rate........

    Well, that's a relief........was trying to figure how to get them to take the net down in time............)

    Suggest you avoid smoking in the dunny, though???

    It's interesting to note that ICP have come out with an 18L receiver tank. The standard kit tank has been 6L. This sits under the baggage area, and while it was probably introduced to increase fuel capacity, it would also move the C of G back by almost the same amount as my 10Kg of ballast.

    The 701 has a different rear stab/tail setup than the Savannah, so I can't speak for the former, Nev. I can say that with the later Savannah S, you run out of elevator authority on landing sooner than with the earlier VG. And on takeoff you can get the nosewheel off earlier/slower with the VG than the S. What seems to be going on is that the C of G, while well within limits, is also well forward, and particularly when lightly loaded. I tend to fly light, I added 10Kg ballast to the baggage area a while ago, and it is a quite different and much easier aircraft to land that way. I've been thinking since of moving the battery back instead, but am nowhere near getting round to it yet....

    JGs VGs are a really nice and well presented product, Marty. They come with precut double sided pads that make installation a breeze. (And no, nobody's paying me to say this!)
  15. IBob
    I'd just say stick to the recipe (kit manufacturer's recommendation). It's quick and easy, none of mine have fallen off and I'm not aware of any other builders losing them. JG supplies precut 3M doublesided tape with his VG kits, which is excellent, but the Savannah wing has locating holes that match twin locating pegs on the VGs provided, and to tape them you would be somehow cutting round the pegs, also standing the VG off the surface.

    P 35 of the wing assembly section says to use 'ciano acrylic' glue, which is better known as cyanoacrylate or superglue. (It's mostly all in the manual.........somewhere.)
  17. IBob
    I used superglue (onto 2 pot painted wing). And it's worth getting the superglue bottle with the little brush in the cap....like nail varnish. It's much easier to apply the right amount neatly with the brush than straight from the nozzle.

    I doubt there's a pilot here who hasn't had his moments. Learn what you can from it. Then put it behind you and push on, I say.

    Hughes/MD500s were also famously used for deer shooting, then later for live capture by wrangling, net guns and tranquilizer darts. There's a fair bit of exciting footage on Youtube, if anyone wants to look at it. And in some locations it got territorial: a pilot friend of mine gave it away after a bullet hole appeared in his canopy during a deer recovery flight.

    Yep, they didn't fly up and down, Nev: just hovered in place until moved to another spot. And it wasn't a 5 minute job, sometimes they were up for hours. This was in one of NZs principal fruit growing areas, principally for export. But I moved out of the area 20 years ago, I have no idea if they still do it.
  21. IBob
    In NZ they are sometimes used to prevent overnight frost damage in orchards at key points in the growth cycle. Or they used to be. Very expensive and very boring for the pilot, hovering in place over a marker light. Other frost protection methods include: Windmills, like small wind generators, permanently installed at various points. Either electrically powered or diesel/petrol. Though the petrol ones went out of fashion after it was discovered the engines were perfect for jet boats, and a few orchardists went out on frosty nights to discover nothing attached to their windmills........... Spraying water on the foliage. And smoke pots used to be used a lot, but around towns they are only allowed them a few times each year.

    Yep, I would like to have read that, but am not on Facebook, and prefer not to be. Is there an alternative source?

    Admin, congratulations on building and maintaining this most excellent resource. The rest of us must go where it goes if we wish to continue accessing that. My only concern is that we not lose the huge accumulated wealth of detailed knowledge and information here. Otherwise, all power to you!

    Kbstone, nice looking build! While mine is an S, the Drawing 14 you have posted above appears to be exactly the same as for the S, where the profile of the 2 sections are as shown (though my part numbers are different): The outer part (your SF029-15) is an uneven channel with the long side turned in to meet the outer screen. The inner part (your SF029-16) is an oblique L section, turned in to meet the inner screen. Neither of the sections in your pics look like those, so I would suggest that either Drawing 14 for your build is not correct, or you have pulled the wrong parts?

    If increasing tyre size, I'd say that's the way to go. I was talking with a very experienced and capable Savannah owner a while back, and he was remarking on how you have to rotate the aircraft off the ground. It doesn't take much at all, but it won't lift off at lower speeds (in steady conditions) while on all wheels. Which is very handy for choosing your desired liftoff speed and point. Also very handy for getting the thing to stay on the ground on landing, especially if lightly loaded.
