The following pictures show a tiny sample of the many FEA studies done on the crankshaft, pistons, rods and wristpins. The V5E comes with 80W engine generator and voltage regulator/rectifier. This engine was completely designed in 3D-CAD (SolidWorks). They seem to offer somewhat better power or performance depending on the application due to either higher engine output or the propeller gearing. Opposed pistons cancel out each others internal inertia forces resulting in an amazingly smooth running engine. In the not-too-big, not-too-small radial category is Australian engine maker Rotec, which continues to supply the most round motors to the experimental market. Ignition is CDI (capacitive discharge) with integrated variable advance curve.

Its too bad the 185-hp Warner hasnt made it back to production as its a perfect fit for many experimental aircraft, especially replicas. This belt-drive development came from apparent demand of the long-prop and WW-I replica aviation crowd, but demand seems to have dropped off, so Revmaster is holding off the expensive tooling commitment until demand warrants the attention. All Spyder Corvair engines are built to order. Best known for his AX50 cylinder based on Lycoming 360/540 parallel-valve architecture, Higgs has combined that cylinder with his own Lycoming-based crankcase and intake designs to arrive at some very modern-looking flat engines that will fit under common kit-aircraft cowlings. Cycle Nomenclature But those dual-mag and starter motor luxuries are available optionally, and the priceand weightare still low. The naturally slow-turning and geared Rotecs provide the sound and long-prop looks so popular with amateur builders looking for either a vintage appearance or who simply want something a little different than the ubiquitous flat-engine norm. , For its popular 130-hp engine, Viking starts with the Honda Fit four-cylinder power plant. The convenience of not needing to mix gas/oil. HP Gold Cup .61 R/C Engine Front Intake.

The V-twin is red-neck proven meaning hundreds of thousands of this engine have been manufactured and put to the test in ATVs. Unless youre building a glider, its inevitable youll eventually need to decide which engine to put on your new build, or perhaps use to replace an existing powerplant. Naturally this gives a fat low-end torque curve, also augmented by the gearbox and Hondas gasoline direct injection. At the other extreme, Rotax is firmly in the Experimental aircraft market and therefore has no need for an in-house boutique or separately named engines. A plug-and-play philosophy is supported by the CAN bus electrical architecture, so integrating the engines into an EFIS or custom tailoring the engine electronic mapping is said to be relatively easy. I should also name LOM Praha (http://www.pistovemotory.cz/en/), who are still offering a range of EASA-certified inline six- and four-cylinder engines from 120hp to 250hp.

This is not a reliability or safety issue, but some builders are only comfortable with a 100%, brand-new engine. Not to be overlooked, all Thunderbolt engines are broken in on one of Lycomings dynos for between 1.5 and 3 hours, eliminating any worries about the engines viability during the first flight, plus relieving the harriedand often apprehensivepilot from following restrictive engine break-in protocols., Typical modifications in the Thunderbolt line are increased compression to 10:1, with the caveat that 100LL fuel is then required (no mogas), along with any number of electronic ignitions. They dont know why, as the Wankel remains available and still a power-to-weight champion, but theyve seen little interest in the rotary lately. The smaller engine is most often paired with a fixed-pitch 76-inch-diameter prop while the R3600, which was later to market but seems to have picked up sales steam lately, can swing 90-inch blades. Notice we said kits, as all AeroVees arrive at the customers door as disassembled engines. Over 30,000 units of this popular 65HP Rotax 2-stroke engine have been sold. , We also recommend spending some time with the companys good online technical information as the fuel system is entirely reliant on electrical pumpsthere is no mechanical fuel pumpso that is something to consider. That means seven fewer set-ups to save both costs and increase machining accuracy. Its reputation for reliability and economy of operation is well noted in aviation community. These are also extremely light engines., Of course, this means youll get good at hand propping and wont feel bad about flying on one magneto because there is but one magneto, no starter or alternator at the entry-level price points. reliability and to provide sufficient strength margins for future developments, including a 160+ HP turbocharged version with a constant-speed They allow slow, 1800 rpm propeller rpm perfect for the wooden props popular on such aircraft.
