Chris_327 42 Posted May 17, 2011 Share Posted May 17, 2011 After watching this: , I have two questions. a. I'm guessing that this is indeed the C-1 right? b. Is the C-1 capable of aerobatics, or is this guy just a complete nutter? Either way, I think Marcel can expect another sale thanks to me, once this is released!

eddt16 1 Posted May 17, 2011 Share Posted May 17, 2011 a: No, thats a DV-20 Katana, an earlier variant of the DA-20 Katana. b: As far as I know it is neither allowed with the DV-20 nor with the DA-20-C1 to perform aerobatics so yes, this guy seems to be a complete nutter.

Jigsaw 20 Posted May 18, 2011 Share Posted May 18, 2011 He probably will realize what he's doing wrong when the wings snap off at some point. I just feel sorry for the passenger who doesn't realize in what kind of situation she is stuck there. Link to comment Share on other sites More sharing options...
Chris_327 42 Posted May 18, 2011 Author Share Posted May 18, 2011 Wow, well I'm surprised that he would actually put his passenger at risk, let alone himself! Link to comment Share on other sites More sharing options...
Snave 466 Posted May 18, 2011 Share Posted May 18, 2011 The wing structure is actually very strong. It's the tail or elevator that would break off first. The main reason the aircraft isn't certified for aerobatics is, firstly, it's not certified in that class (chicken and egg, but it's worth mentioning) and mainly, the Rotax does not respond well to being inverted in this form. Manufacturer limits are no more than 5 sec at negative G and at a maximum of -0.5g - usually, aircraft with Rotax 912s that ARE going to be used legitimately for more advanced manoeuvres have an additional oil pump or oil pick up included in the crankcase (the 912 uses a blowback system to return oil) to prevent oil pooling or oil starvation. The pilot doe not break the engine limits in the video, but that doesn't make him any less of a knob. Link to comment Share on other sites More sharing options...
