Looks like a very nicely built aircraft CharlyT. 👍

Photos taken inside the hangar at night….No power connected to the hangar just yet.

Whilst I never pass up an opportunity to take a shot at CASA, the system worked flawlessly for me....Easier than ordering a Sunday night pizza from Uber.

Stress free

Well that was easy enough.

Move over ROTAX…..move over PEUGEOT

There is no blanket requirement for TSO’d instruments in 19-XXXX amateur built RA-Aus or experimental GA to fly in controlled airspace. Here’s a reference: https://raaus.com.au/wp-content/uploads/2023/10/raap-14-can-i-fly-in-controlled-airspace.pdf

It’s likely aimed at the owners of C150’s, Tomahawks and Air Tourers who have had recent exchanges with CASA medical staff.

The precise wording on the RA website is: “There are currently 3232 active aircraft in the RAAus fleet.” Since registrants are invoiced annually, I’d interpret “active” to mean “currently registered”, but I’ve been wrong before today.

3,232 as of 26 January 2024

They become unsecured creditors and wait in line with all the other creditors for a refund.

The Oxford Reference Dictionary’s entry for “Legend”: A traditional story sometimes popularly regarded as historical but not authenticated. On that basis he likely qualifies, although I’m now going to look up “Popularly”. Move along please folks, there’s nothing to see here.

Just reread my post and realised I used 790N instead of 700N….Despite the error, the outcome remains the same.

If it were me, I’d initially keep life simple by sticking with all 22001 dimensions except the OD. Some (very) basic stuff assuming a 70kg engine and prop combo….Call it 700 Newtons for simplicity. Original mount net area 790mm^2 x 4off = 3,160mm^2. Compressive stress = 790N/3,160mm^2 = 250kPa With a 1-1/2” OD the total bearing area increases to 4,216mm^2 or 33% more. So compressive stress decreases to 790N/4,216mm^2 = 187kPa. By implication, the compressive strain on the mounts will also be decreased by about 1/3 and along the way, you’ll have increased the surface area to dissipate all that vibration (kinetic energy) heat into the aluminium mounting rails. Naturally, the back-up washers will also need to be increased in diameter. It’s pretty easy to cast urethane and there’s a bunch of videos on YouTube showing people doing it at home….Search “casting polyurethane bushings” and pour yourself a drink. If you’re still unsure of your ability (it’s easy) then pop over to 33 Holloway Dr Bayswater and talk to Melbourne Polyurethane.
