The Cavorite x7 is an interesting radio controlled model. Can it be scaled into a useful full sized aircraft? None of the amazing RC 3d fixed wing or helicopters types have full sized versions

The most common and cheapest 912uls is not on the list. If we take the cheapest on the list and divide by 2000 hours it comes to $27 per hour, good value for a commercial operator. how cheap do you want it? Remember liability insurance and other costs associated with aviation would not be cheap. The good thing for home builders is the good supply of very good used ex flying school engines at very reasonable prices, $5k. The most expensive engine on the list, the 916, which would be very very nice in my RV6a is comparable in price to a new experimental lycoming o-320 160Hp engine. You get what you pay for.

Would have been a runway excursion or ground loop if it was a tail dragger.

Onetrack,I would have to disagree with the "arsey-ist" bit. The guy is obviously a competent pilot. It has been my experience that an aircrafts flight path can be controlled in close proximity to the earth with great accuracy, + or - 1m, even while turning or rolling out of a turn onto the centre line. Practice makes perfect.

Just need someone to create a supplemental type certificate, STC. In RAAus land an STC is called a MARAP. The people that develop STC recover the substantial cost by selling the STC to many other people that also wish to modify their aircraft in the exact same way. Example, fit a Allison turbine engine into a Cessna P210 in place of the piston engine. Thus a Silver Eagle in born. https://www.aopa.org/news-and-media/all-news/2018/october/pilot/turbine-quick-look-silver-eagle

Pat, have you bleed the system from the wheel cylinders up using a syringe or pressure bottle? Suck all the fluid out of the reservoir then pump in to the wheel cylinders til no more air bubbles apear in the reservoir. The beringer valve, which I would remove, may have a shuttle valve in it to do what it does so it may have different requirements for bleeding. Need to use the correct fluid as others have said, most aircraft use hydraulic OIL not brake fluid. If the Orings have swollen from incorrect fluid it may be causing the master cylinder to not return fully.

If RAAus cannot help you my guess is there is no pathway. Ultimately CASA is the regulator. To make an engine change on say a Cessna 172 a STC, supplemental type certificate, is required. Perhaps @Rapture can advise you how they are planning to proceed with their Jabiru/zongshen build.

I have never had one, 40 years of very successful two stroke flying now. Hopefully the endorsement instructed pilots to read the engine operation manual, POH etc, no different to any other aircraft or engine system.

Pretty sure Tom's Jabiru is an amateur built 430 with VH-rego so he can do what he likes.

The brake master cylinders at the pedal has to have a spring, usually internal to work correctly. The brake pressure regulator IMHO is an unnecessary part / complication on a simple light aircraft.

You should read the provided link above a few times then you may understand how the whole system works. No individual approved person is going to pass an aircraft that are not airworthy.

This one, formerly VH-PUK had been repowered with a lycoming O-235, 112hp? so should have been a good performer. Ferrying a 1946 Auster J2 through Australia : Air Facts Journal AIRFACTSJOURNAL.COM The aircraft ferry game is both interesting and where one always expects the unexpected. My card reads "Can Ferry, Will Travel." Flying an older aircraft cross country is more than just throwing your bag in...

Lycoming O-235 has the record for longevity I believe for an engine produced in numbers. 1942 to 2025 with almost no change in design or materials. For the Hummel mine would have a 503, best power to weight no question.

In 2019 we flew up the western edge of the lake then followed the Diamentina river to Birdsville in the mighty Musketeer. Was amazing. Going out again in June. Last pic was 3500 agl, would have only just been able to glide to the edge of the river, about 15km wide.

Aircraft looks to be at end of the strip, to much brake?
