Rotax $37,000. There is nothing wrong avoiding Gear Box, Turbos, liquid cooling and Elec Eng Control.. It is maxed out at 140HP. Direct drive, aircooled has advantages.
Regulatory incompetence! Imagine if the Faa was running wartime aircraft protuction. Willow Run produced a B24 every hour or 650 per month. A B24 was produced every 15 minutes in total! Now they can't certify an ignition system in 5 years. The difference? Bureaucracy and predatory lawyers!
About the Tiara commercial viability : read a great book by Bill Gunston stating that its architecture made it more expensive to produce but not bringing enough benefits to aircrafts manufacturers to justify the higher pricetag.
Air frame and Engine manufacture Op manuals have had OVER SQUARE settings. However thare are REAL limits due to prop vibrations for example.... I guess your ignorance is your bliss.... Bottom line follow the manuals they are written using engineering data and they are smarter than you....
The “old stuff” design is still maybe the most reliable but 10 mpg or worse is just nuts!! Flying airplanes should be fuel cost efficient over automobiles but they are not. Time efficient maybe but certainly not carbon efficient.
Wait, Charles Lindbergh got the entire Army Air Corps to run LOP during WWII, so all those pilots just forgot that lesson until just a couple decades ago?
Mike Mags work well in planes to this day, RELIABLE, GOOD SPARK, SEKF POWERED AND FUXED TIMING WORKS FOR AIRPLANES. EI has little advantage in planes but in cars that change power constantly EI is helpful. As a kit plane builder (experimental) I have used many EI (lightspeed, eMag, SDI, Suefly). Cars don't drive at 75% all day so EI benifits is less from mapping timing advance. SUREFLY and others are now available for certified planes. EI ARE NOT 100% RELIABLE MIKE. If you go to altitude and fly at low power advanced timing more than 25 Deg BTDC. The Mag works and is electrically independent.
The current designs are the zenith of piston engines for aircraft in the 100-400 HP range based on BILLIONS of research and development.... Make a better experimental engines, an AUTOMOTIVE conversion... I hear they are MODERN and better. NOT ONE HAS BEAT THE Lyc or TCM.... Clearly Turbine (turbo prop of high bypass jet) is best but not practical for low HP GA use if low utilization.
Mike challenge, design an engine to compete with IOX-370 or IO-360 (170-210 HP range). You lose. Nothing you said makes any difference. Nothing in math, science, metallurgy, design, engineering and manufacturing has changed. What small changes have occured Lyciming and TCM have exploited. Electronic Ignition is available for experimental and OEM planes. EFI is available for experimental airplanes. Please use facs and logic. The reason that other engines never CAUGHT ON? Think about it.
You are using the internet to watch a video..... why aren't you back reading a book about this. It worked... that didn't need any external power. Was that all that counted? Just think about what your saying.
@@gusbisbal9803 electronic mags also get energy input from the same way mechanical mags do. They're both converting mechanical energy from the engine to a spinning magnet which induces a voltage in a coil of wire. The difference is in the electrical pulse distribution. In a mechanical mag there is a mechanical armerature rotating around in the distributor cap. Electric mags have a solid state distribution ie, no moving parts. No moving parts and no mechanical wear implies a longer Mean Time Before Failure or improved reliability and less owner maintenance costs. The only reason we don't use electronic mags is because it's too expensive to get one approved by the FAA and there's not a justifable return on investment.
Mike I am disappointed in your lack of logic here. Old means bad? So a P-51 is a not great? Why reinvent the wheel. All modern aircraft engines, Lycoming, Continental have made improvements in materials, manufacturing, coatings, as well as fuel injection, SINGLE LEVER FADEC and Electronic Ignition, turbo intercooled, water cooling.... Why reinvent the wheel. If you had blank paper design it would be a DIRECT DRIVE, AIR COOLED, PISTON ENGINES..... Mike if you are so smart... PLEASE DESIGN A NEW ENGINE.

Extreme tendency to lawsuits definitely slowed down GA by much !

Waiting to hear your talk about running the engine over square. I've been told I would turn into a pillar of salt if I ever did that. LOL

If it works don't fix it!!! Magnetos still don't need external power........that is all that counts.
No, it's not all that counts. The Gnome rotary worked. The OX5 worked. Should we have stopped there??
You are using the internet to watch a video..... why aren't you back reading a book about this. It worked... that didn't need any external power. Was that all that counted? Just think about what your saying.
Listen again, emags don't need external power after start-up because they contain a built-in generator.
