  1. as one of the advantages of the Savanna over the 701 is that the middle part of the wing also provides lift?

    One of the disadvantages of the 701 is that just where you need the headroom is right where the roof line dips down to meet your headset.

  2. will be things for two bikes, unless I find an even smaller one.

    JG3(member on here) puts a folding bike in a turtle deck on the exterior of the rear fuselage, that would work better on the square fuselage of the XL rather than the rounded S model fuselage but it is doable.

     

     

  3. One style (heavier) has old style White Gel Coat finish and is much easier for new builders to achieve a satisfactory painted finish, The other(mush lighter) is opaque finish which is not smooth on finished surface requiring much more filling and sanding to prepare for paint. Since some people install one fuel tank in one wing and two tanks in the other, I am not sure that the difference in the weight would be of great concern.

     

     

  4. What are your cowlings are made of? And has somebody have weighed his cowling???

    July 2013 kit has the heavy white cowling, Aluminium wing tips and white heavy white molding for front third of tip. Soon after this they went to the clear light weight unfinished looking cowling and full wing tip of same material.

     

     

  5. wouldnt you start from the middle of those curved sections and work your way out? I would have it all clecoed first and do one cleco and rivet at a time...but any advice would be appreciated as we will soon be doing this

    I found I couldn't get the middle to curve around the corner because it fought me on both sides. I think I got into trouble starting on the big end working to the rear, but I can't clearly remember. It is quite a while ago now...isn't it?

     

     

  6. It's interesting, too, that for some parts there are good and 'bad' sequences of clekoing and fastening:!

    Especially true for the corners of the rear fuselage joining the side sheets to the upper and lower sheets. I you are doing it wrong it will build a tension and carry it along until it builds beyond what the material can take and it will try to pop a nice fish scale dent in the curved corner section. From distant memory I can't recall which end to tell you to start but if you choose the wrong end you will experience exactly what I have described. Stay alert and you can see the tension building before any harm is done.

  7. Thanks for that, Steve, I can see the sense of what you are saying.I'm not spending much time in the workshop at present, but will hopefully get some time this week. Like most of the 'tricky' bits on the build, I'm sure it will resolve with a bit of thought.

    So far I have found that a good nights sleep often brings insight into something I just can't resolve while I am awake. Everything is clearer in to cool morning light.

  8. I found that the bolts around the cabin wall being in thinner material had to be installed first then lever the holes in the main spring channel to align the holes in the stay mounts. Being heavier material it was able to take the heavier alignment. It seams that this stretches the cabin walls outwards giving the tension to the whole assembly. If you bolt the mounts onto the channel first there is way too much distance to cover with AN3-05 bolts.

  9. I found them at those and other locations except they wont sell just one fitting, they sell the entire pack...anywhere from $24 to $40. I just need one $4 fitting and I'm amazed Aircraft Spruce did not carry that size.

    Sounds like you are about to become a distributor!

  10. .... and rerivet with spacers betwen rib and skin.

    I am not sure about all the packing people put in, some use aluminium, others use epoxy fillers. The computers at ICP design the structure of the assemblies and the tensions on the sheets are part of the design, including the distortion of the sheets caused by the tension. All the fill and packing adds weight and changes the design. The ribs under the wing nose skins for instance are not designed to be smooth, nor the sheets on the ribs of the flaps and ailerons.

  11. Raising the flaps promptly on landing can be good in some STOL or windy situations.

    This can be a trap too! On about my second or third solo training, I put away both stages of flap in one motion and promptly began sinking. I quite simply hadn't built enough airspeed to fly clean and just began sinking instead. Manual flap allowed we to quickly reverse my mistake but it was a good lesson.

     

     

  12. The last rivet before the trailing edge in each rib is a problem fouling on the tail of the one coming from the opposite surface. The first gives no trouble, the second give great grief. With slight pressure on the rivet gun, the tail can be offset and straighten the gun as it fires. The standard rivet is really too long for this situation but a good result is achievable with some practice (read drill out the rejects).
