    I did a test run on my new skid plates .. worked like a charm (for now).

    Truly a wet and dreary day out but this neon purple really jumps out. Right now I'm working on a ground mix. An elevator curve against the throttle input to hold her down. Another thought was spoilerons and a down elevator curve. I'll have to see what I come up with. The net goal is two flight modes... Ground mode and fly like airplane mode.

    Also noted there is a significant difference in a COG for a steady flight versus a COG for a good ground mix. I'm still working to find a good "split the difference" mark on battery placement.

    Sled vs catamaran ... only one will remain upright. Show time .... this winter's blow down and be there.

    I really hate to admit this out loud but I'm actually wanting snow now that I can play in it.

    A big field you say ... so I decided on a park. I put together an idea for a ground mix and wanted to see how she would actually fly.

    A quick adjustment to ground mix and move the battery a little more forward.

    I like it !! ...It fly's easy. This will be one of those "just gotta have" planes to play with in the off season.

    Excellent. .. I'm confident that you're going to like this one and it just looks so unusual.

    Look forward to seeing it.

    A quick follow up report. .. my plastic laminate did not stay attached.

    I think I'll move over to the Malukk approved method of brown paper skin on the underside of the runners next....see how that holds.

  11. If you also want to make it slippery, use zpoxy (used for glassing) and it will make the surface smooth and slippery - just like sliding shipping tape on wet grass :)
    I even thin out zpoxy with isopropanol - not the best thinner but it makes it milky and thin enough to flow on the surface...
    On my ikon a5, i did not do brown paper but just the thinned zpoxy worked fantastic - i was able to take off from closely cut grass...

    @malukk
    Did you ever tried the 20 minutes "finish" epoxy for laminating (glassing)?
    It should be more liquid than the "normal" epoxy, but I haven't try it yet.
     
  13. No I haven't... When I went to the hobby store nearby, they said that zpoxy is the thinnest epoxy that they used so just went with that... It also makes the surface a bit tough - added protection for dents and dings...

    I kind of want to build one of those without the wings! That thing really moves across the ground!

    I have a follow up. . I've been struggling with skids on this bird and as you can see the floats are taking a beating. I need something that is slippery on grass and something that will finally stay on. I've burnt through everything else I've tried up to this point... everything else has fallen short.

    This time I'm going with a plastic 3 ring binder. Soft, pliable and so far, the heaviest thing I've tried to use for this.
