There seems to be a lot of people watching his project, many with expertise that may be helpful. I wonder if anyone has ever tried an open source design, such as many tech companies do with software development. I put an EFIS system in our C172 test bed for flight testing because it recorded a...

A lot of criticism. Personally, I’m glad there is still some out there trying new things. The market is too small for any big resourceful company to try, let alone the liability issues/risk that drives most away. That’s why GA is stuck in the 1950s other than some modern experimental designs...

Sorry for veering off original topic. I’ll answer earlier posted question and go-around. I think most of the issues surrounding failures of conversions were due to lack of resources in their development. Many early conversions were simply experimenters taking engines from a junk yard...

Sooneraviator I don’t know of any concern or issues with a belt drive system on firewall side, other than having the room to service that side of the engine. As with anything in aviation, there’s trade offs. Moving the engine forward moves EOW CG forward, but allows more room for servicing. So...

Mbdigad man- Not sure where you received your engineering degree or expertise on engine conversions. From your less than informed comments RE your list of insurmountable issues, the very items you list as problems are actually benefits, and proven so by all other engine industries being far...

I was is same dilemma, I didn’t have time to build a kit plane, not comfortable buying a plane a non professional built, but didn’t want to spend the ridiculous money on a certified antique. I ended up with both, a Cessna 172 with a V8 experimental engine. It was a good choice for me, at least...

For what it’s worth, I would reference some AIM and ICAO procedures. But essentially they say using full call sign on initial call and there is no reference in contracting call signs. If ATC shortens your call sign in their response, than it’s acceptable to shorten it. ATC will normally shorten...

To clarify my prior post regarding FADEC throttle (per an earlier post RE electronic throttle control issues).....my C172 throttle is actually a mechanical linkage to the engine, in fact it’s the original C172 cable throttle control, whereas most FADECs are electronic and use wires to send...

My C172 has a Corsair V8 engine conversion and it works far better than the original Lycoming.... original engine cost me over $60/hr with fuel, oil and overhaul reserves, the V8 is less than $20/hr. So, it makes economic sense for me as I teach my daughter to fly. It also makes it easier to fly...

This thread seems to have experienced mission creep.....not sure what legal arguments regarding employee classification makes. my point was simply the FAA needs far more DPE’s to keep cost in check and allow for easier and quicker check rides. The DPE program was never intended to provide a...

There’s always conservative nay sayers for aviation start ups, with good reason. But anyone that is trying something new I wish them good luck. GA is stuck in the 1950’s yet still too expensive for most. After reading this thread I looked at their YouTube of first flight and it’s encouraging...

The FAA technically designates a designee, meaning they neither hire you or contract you, but simply designates that you represent them specific to the approvals you are given (such as only private pilot check rides), and that such designation may be revoked at anytime. You can have the...

One of the experimental forums has a section just for auto conversions and the $20/hr sounds about right for the HP. There’s a C172 nearby that’s been in a hanger for years after a prop strike just collecting dust and thinking about seeing if they want to sell it.....maybe get a good deal, and...

Reserves typically refer to engine overhaul. Not sure I see your point. Cost of flying is absurd, seems something like such new thinking in this ancient industry is a huge step in the right direction. If cost can drop to $20/hr, or even $50, for something like a C172, there would be less...

As a former designee, I can tell you the designee program is a license to steal. Most FSDOs only appoint a few designees, usually fewer than needed, usually because they don’t want to be responsible for oversight (more work) and most FAA inspectors become designees after retirement so they need...

ADSB report GPS altitude, at least in simple GA units. My wing mounted ADSB out has no pressure sensor or connection to the transponder encoder. I think many of the flight following apps also use ATC derived data if the aircraft is IFR or VFR flight following and in radar contact, at which case...

The airfacts article says the $20/hour is operating cost with fuel, oil and reserves..... not just the fuel. Big savings over a O-360 at about $60/hr. There are plenty of experimentals flying with car engines safely now and seems logical to apply to old certified aircraft. But didn’t Porsche...
