All the dimensions will be released to the public upon testing of our buoyancy. We have ordered a set of DIAB Divinicell/ Divinimat products and expecting the delivery in three four weeks. We spent yesterday a few hours talking to spar manufacturer also in a very close distance from our home airport FORTECARBON.COM Some of their products will be used in our seawingsHow wide are those sponsons/seawings?
The original plane looks like thatWater handling characteristics...has this hull been tested? The nose shape seems significantly different than all the other LSA amphibs.
That is correct - we won't be using that hole for walking on top of the fuselage. But will keep that V-like tail as a link to our design roots and for our ability to balancing the plane that is becoming much lighter than the originalI would think the walk through tail feature becomes irrelevant when downsizing. Not much of a hole left to get through.
Dear Jan, We will be making the molds in the future. That is for sure. But our molds will be a bit different from the traditional "plug" --> "mold" --> "part" workflow. We are building our prototype as a "plug" . The plane is built from an aerodynamically cured model . Then we will be test-flying that prototype as the proof of our technical characteristics required by LSA rules. That might take about 200 total flying hours to prove our design. Then we will take this plane apart and starting cloning it per our coop's request using the hard plug heated stone mold technology. But the mold will be taken not from a foam based plug but from the "real plane" . And it will be vacuum bagged each part made from that stone mold of up to 100 parts can be produced from it. By cloning the "real plane" we will be absolutely sure of any aero- and hydrodynamic improvements that will be found during the test fly phase of our project. That is in regards to our boat-fuselage. The wing will be produced slightly different and it will be shortly when we start doing this type of work. Will demonstrate every step of making our wing from the ground up.I realy like the look of this sea plane, would it not be a good idea to make a very good plug and mold from start if you are planing to sell hulls or kits? uneven wrinkeled hull skin will not tell the potential buyers that this plane is well built, even if strong enough and good aerodynamicly.
Dear dino many thanks for your question. yes - the official way of classical SPAR construction would be C shaped Unidirectorial carbon sandwich laid in multi-layers mold , cooked and cured as supposed to be treated that staff. In order to reveal the technology - let us wait for a couple of weeks may be a month to share with you our vision of the wing construction. It is a bit of an "out-of-ordinary" technology. Might be looking strange to some who is not experimenting But I promise to share with you all the tests upon our completion to make sure that our method is legit. Will see the success or our failure exactly as it is supposed to be done in EAB construction. We will be following the "probes and failures methodology" as you may be aware ofWhy weave when you need unidirectional fiber orientation in the spar cap and +-45 in the web?
