DrZoos Posted December 2, 2013 Share Posted December 2, 2013 Hi guys I have a factory built Alpi Pioneer 300 which is a certified aircraft. Its a 24 rego and registered with RAAus as a factory built Non LSA I want to fit these vista vents (by an L2) which are FAA approved and in the usa do not require an STC see : http://www.aircraftspruce.com/catalog/appages/vistavents.php Go to the Q&A tab under the picture Is this the case in Australia , can i fit these without an STC because they are FAA approved ?? PS it must remain full 24 certified as i want to be able to go into CTA and i want to be able to put the aircraft online Link to comment Share on other sites More sharing options...
DrZoos Posted December 2, 2013 Author Share Posted December 2, 2013 Pretty certain i still need manufacturers written permission, is that correct?? Link to comment Share on other sites More sharing options...
Thirsty Posted December 2, 2013 Share Posted December 2, 2013 If it's not an LSA doesn't that make it certified with a CASA issued CofA? In which case no mods are allowed without a CAR35 (or whatever they are now) engineer signing off on it. My J160C is that boat. Link to comment Share on other sites More sharing options...
Downunder Posted January 29, 2014 Share Posted January 29, 2014 How did you go with the Vents? I also have a "24" and believed the manufacturer has to approve all mods.. Link to comment Share on other sites More sharing options...
DrZoos Posted February 2, 2014 Author Share Posted February 2, 2014 My manufacturer approved them, but im so far not game to drill the perspex as we havent found a decent way to the vibration. So right now im exploring bigger tubing from the duct to the outlets and bigger outlet. I will keep you posted. Link to comment Share on other sites More sharing options...
Downunder Posted February 2, 2014 Share Posted February 2, 2014 Yeah, risky drilling prespex. Probably better running the ducting. I belive there are special bits for drilling perspex and it's best done in veryhot weather (softens it abit). Link to comment Share on other sites More sharing options...
Yenn Posted February 11, 2014 Share Posted February 11, 2014 There are special drills available for driling perspex, or you can resharpen them yourself. I forget the angle to grind to. I gave used a 3.5mm router bit in the router to cut holes for the circular vents in my Corby canopy. You could probably use a dremel tool, I will see if I can find a scrap piece to try it out on. 1 Link to comment Share on other sites More sharing options...
PA. Posted February 12, 2014 Share Posted February 12, 2014 When drilling perspex use a dull drill bit. A sharp one will bite in a crack it. If you don't have one I am sure I have a box full. Link to comment Share on other sites More sharing options...
facthunter Posted February 12, 2014 Share Posted February 12, 2014 Have you considered glueing it? Drill the holes before cutting the hole for the vent if you go that way. Reduce the bottom rake angle on the bit to almost nothing. ( same as you would for any thin sheet even though the Perspex is not that thin).

Old Koreelah Posted February 12, 2014 Share Posted February 12, 2014 When drilling perspex use a dull drill bit. A sharp one will bite in a crack it. If you don't have one I am sure I have a box full. A blunt drill in effect melts its way through the acrylic. Use a steady hand and don't force it. A dremel grinding bit is a pretty safe way to cut out a section. Link to comment Share on other sites More sharing options...
Guernsey Posted February 13, 2014 Share Posted February 13, 2014 Any ex serviceman will tell you how its done...they have had a lot of drill practise. . Alan. 1 Link to comment Share on other sites More sharing options...
