There is a string on this topic on Rotalk from 8 years ago. Here is one skeptical comment from this string : Re: Polishing intake manifolds by Bill Hertzel » 8 years ago I am confused. ??? A week ago you were asking about the possibility of Modifying your crossover pipe. Yesterday you post pictures of the manifolds before and after welding. This afternoon you report a test flight was successful. 6 hours later, the Parts are available for mass marketing on an Italian website. Either this is the fastest engineered project I have ever heard of, or I am missing something. :unsure:

Not sure if this one has been discussed before……but here is yet another weird engine design.

The gliding fraternity are big on sealing airframe gaps. There are specialist sealing tapes for the really serious - they are a tad more elastic than say, electrical tape, and don’t leave a residue. There are also leading edge tapes for those that choose to fly off gravel strips and through locust plagues.

May be speculation, but I heard there was grass in the fuel ??

Those cables may be over 80 years old ? May have been originally gal, but the gal has long gone. 316 is certainly susceptible to sudden failure ( usually chloride induced stress corrosion cracking) but Narromine certainly doesn’t have any marine influence, so I would think 316 would be fine.

interesting what a tied down plane can do while you’re sleeping. https://www.facebook.com/reel/2413059642482637/?fs=e&fs=e

….and the RPL holder has a current CASA medical.

I have no knowledge of the matter, but I can theorise what training packages would need to be developed within RA-AUS to then roll out to instructors to effect a CTA endorsement. Then making sure instructors are actually current with Class C and D procedures themselves, and also have access to an aircraft with the right gear to enable instruction and entry into CTA. All of that takes time….and maybe a decade or however long it has been since first mooted, hasn’t been long enough.😎

CASA just released feedback on their Class 5 medical survey. The majority of respondents indicated Class 5 holders should be allowed into CTA. No big surprise there - other than a Class 5 being the minimum.

Curious - I just checked mine, and I only got an extra year !!

After all this dialogue I still don’t know what you call the person not in control of an autonomous drone.

Those old enough to remember the tandem engine ‘Super70’ Chamberlain tractors may recall their oddity. Contemplating a tandem engine concept in a modern aircraft is certainly odd.

I’d prefer this one. https://aviationconsumer.com/aircraftreviews/fk12-comet-sporty-aerobatic/

It’s a pity Rotax dropped their 6 cylinder 936 engine prototype before commercialisation. From memory it was around the 300hp mark.

This might be a fantasy, but what other options are there for a drop in IO540/550 ‘modern’ replacement ? Copied from PabloSniper Mundo & Tecnologia Facebook page Twin Rotax 916 Power Package Concept A Modern Replacement for Legacy IO-540 / IO-550 Engines Summary We would like to develop a dual-engine Rotax 916 power package designed to replace traditional IO-540 and IO-550 installations. The goal is to deliver equivalent or superior power, built-in redundancy, and excellent high-altitude performance — all while keeping weight and required airframe changes to a minimum. A key requirement of the project is that the entire assembly must fit the same engine mount footprint used by IO-540 and IO-550 engines. Additionally, the overall length of the two Rotax engines installed in tandem is very close to that of an IO-540 or IO-550, making this concept physically compatible with existing cowlings and firewall spacing. Why This Concept Makes Sense Modern Performance With Redundancy Two Rotax 916 iS engines produce 320 hp, allowing this package to directly replace the 310 hp IO-550 found in aircraft such as the Cirrus SR22 — with the added benefit of turbo-normalized power maintained at altitude. Similarly, a pair of Rotax 915 iS engines deliver 282 hp, making them a modern replacement for the 260 hp IO-540 commonly used in aircraft such as the RV-10. Comparable Installed Weight Although each Rotax engine is lighter, the full assembly — engines plus the shared shaft system — should be considered practically equivalent in installed weight to an IO-540/550. This keeps CG and structural considerations close to existing standards. Efficiency, Fuel Flexibility & Lower Operating Costs Rotax engines offer exceptional fuel efficiency, smooth operation, fully electronic engine management, and — importantly — the ability to run on automotive gasoline (MOGAS). This means the kit could be applied to any aircraft currently using an IO-540 or IO-550, providing a modern, fuel-flexible alternative with significantly lower operating costs and easier global fuel availability. Few Additional Modifications Required The design goal is a clean installation requiring few additional changes, making it practical for OEMs and retrofit applications. Matching both the engine mount geometry and the overall length envelope of the IO-540/550 is central to this concept. What We Are Looking For We are seeking a strategic partnership to co-develop a complete, modern engine package capable of replacing the aging IO-540 and IO-550 families with efficient, redundant, altitude-capable powerplants that fit existing engine mounts and appeal to both new aircraft manufacturers and the retrofit market.

Professional drone operators can liaise with an ARO to have a notam issued for an airfield for the duration of their activity. Reasonably common around mining activity near regional airports where drones are used for mapping. Clearly though, a lot of drone operators may not be ‘professional’

I believe the aircraft was an RV-8

There is a Sonex canopy for sale on Aviation buy sell swap, Australia. I have no idea if this is compatible with your machine, but thought I should alert you to it, regardless. i don’t know the seller.

Maybe viewed as the very high end of recreational flying, but I’m sure a lot of people here admire and respect Beechcraft aircraft ….even the ‘doctor killer’. Textron are rationalising their product line and moving this segment to SETP. https://avweb.com/aviation-news/textron-to-sunset-baron-bonanza/

I flew from the Murray River to the Hunter Valley around a week ago. The ‘green’ didn’t start until north of Wagga. Lots of crop failures in Victoria this year and a dry spring knocked yields around in parts of central western NSW. For those that know the area, north of Dubbo the crops were pretty good. i think these pics were near Cootamundra, but I wasn’t the photographer.

I suspect they’ll want a squawk from a transponder as well. The previous airspace version referred to Class D+. Whatever the heck that meant….and of course unique to Australia.
