All,
we recently bought a Corsair Master Series from a local retail store here in Germany and immediately became huge fans of FT scratch builds. This was out first self build model (and second rc plane ever) we flew ... and it flew! And ... it crashed. The latter was mostly my stupidity, after three loopings I dared to try a roll and failed spectacularly. It was a very nervous plane to fly though as far as I can tell. I think the elevator had too much throw (did not adjust using any gauges) and it probably was still a tad tail heavy (only used a 3 cell instead of the recommended 4 cell. So no complaining here at all, this is just our learning experience.
But I wanted to share a couple of thoughts though:
There is one point in the build video where a transition from a paper covered to a non-paper covered section of the wing surface gets stiffened up with the application of hot glue. It is in the video at 12:50 (and similar at other places). I did this and ended up adding a slight crease to the wing which looked good but prevented me from matching the upper wing surfaces together later on. It's good to put the part on a flat table for drying.
Also, after glueing in the servos for rudder and elevator I found that one ripped off rather quickly. I added (much) more glue then and it survived the maiden flight (it did stay in place during that cash), but I still felt uncomfortable. Also you could see how the fuselage wall was bending as the servos
moved. I decided to print servo holders. You can screw in the servos and the holder offers a much larger glueing area.
Also as we did not fly the power pack c (difficult to get here in Germany) I printed a different firewall.
Let me know if anyone it interested in the STLs.
