These engines are aimed at the hands-on enthusiast whos happy to assemble his engine and keep the cash that would have been spent paying the shop to do the same. They are accustomed to working nationally and internationally, so crating up their wares to Kuala Lumpur or the like is not an issue. today, mainly from new old stock, are experimental-only powerplants. Its unlikely, but there may be a handful of parts loose on the market with 185X numbers on them as the licensing agreement required all new parts to be identified as 185X pieces, and a very few parts were made (no complete engines were built)., The Warner type certificate holder is John Duncan who does business as The Warner Engine Company. , The Superior cold air intake is its more popular offering, not only due to the efficiency of the cold air design, but also because it is available in traditional updraft or horizontal layouts. P-MAG and LightSpeed Engineering Plasma series are popular. HP are expected as development continues. After careful This engine embodies innovative technology and features which provide high output, low fuel consumption, and extremely reliable operation in aircraft service. The horizontal cold air allows a slimmer cowling and eases packaging a ram style air inlet, while the updraft version accommodates existing standard-depth cowls. Naturally this gives a fat low-end torque curve, also augmented by the gearbox and Hondas gasoline direct injection. The updated intake offers extra power more than just bored . Theyve also provided important competition to help keep costs in line across the engine marketplace. Canada sales are through Archie Dobbins, operations manager of Firewall Forward Aero Engines.

Im not aware whether they are still selling to homebuilders, but there have been some experimentals powered by LOM engines in the past. They expect several more of its engines to fly by next spring., CAM is part of the burgeoning replica and restoration scene in New Zealand and has a well-established business replicating various warbird parts, especially P-40 items. The parts used are the same ones used in new engines, and if the job is done at the factoryboth Continental and Lycoming offer such servicesthe engine earns the title of remanufactured. There are distributors, but they have no timing component as timing is fixed. 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 F-23 is an amazingly smooth running opposed cylinder engine. Obviously, reliability is crucial to safety when talking about aircraft engines, so hopefully theres no need to belabor that point. These relatively lightweight and compact engines are designed for higher rpm, therefore they all include a built-in spur gear propeller speed reduction unit (gearbox) to optimize propeller rpm. Get your aero motivation here! This System enables the high compression V5 to be easily pull started by releasing 80% of the compression during cranking. By working with William they claim their combinations are built from 90% new parts and are sufficiently inclusive to be true one stop shopping solutions to a running Corvair. There are two gearbox ratios available; some can accommodate hydraulically-controlled constant-speed propellers along with either left- or right-hand rotation. Hummel reports activity is brisk, with the lead time for a new engine running around eight months. - 4 Cylinders - 145 lbs. , Standard Rotec induction is a simple Bing slide carburetor, but Rotecs ownand still quite simpleTBI Mk 2 throttle-body fuel injection is optional.

Were not going to cover Pratt & Whitneys latest turbofan, nor are we delving into the ultralight enginesless than 50 hp. , Given its bent for simplicity, the D-Motor is understandably not a real fire-breather. A big-bore version of the much more common 165 Warner, these radials were good engines in their day, and according to John, given modern manufacturing capabilities should prove bulletproof reliable, with good power-to-weight ratios packaged in an attractive size for personal aircraft use. Superior is quick to point out that theyve upgraded materials and manufacturing processes to provide better parts at competitive prices. That gets you the three-ring piston upgrade and Savarese ignition, along with overhauled air compressor, carburetor and oil pump, test stand run-in, all work being done in Romania. It is the SD400 box beefed up with an external brace, much stronger prop shaft, larger bearings, different splines on the top gear drive, all to better withstand gyroscopic loads. , Built in the Czech Republic by a small company thats been in the airplane engine business since 1993, the Verner radials were detailing here use the same two-valve, 3.62 x 4.02-inch cylinder, but fit five, seven, or nine of them as power needs rise. , Notable improvements are a reinforced magnesium case, one-piece crankshaft with integral propeller flange (like Lycoming, Continental, et al. The Aeromarine V-Twin is a 60hp liquid-cooled 4-cycle 800cc 80-degree fuel-injected, electronic ignition engine with electric start. While we take considerable effort to insure accuracy and completeness, we appreciate any help in increasing the quality of our work. Lets also note the flathead combustion chamber is hardly the last word in efficiency and certainly would never pass emissions testing as an automotive engine, but for the moderate compression ratios run in aircraft engines and without emission limits to contend with the D-Motor proves its contrarian point. Otherwise, one of Verners larger five, seven, or nine-cylinder radials has the compact dimensions to fit a number of fun-flying personal planes and give them the unmistakable round motor look, feel and sound. Notice we said kits, as all AeroVees arrive at the customers door as disassembled engines.
