What is the appropriate rpm for cruise. At present I set about and usually cruise about knts. Page 1 of 5 Start Prev 1 2 3 4 5 Next End. Roger Lee. Hi Ian, rpm at WOT is a tad too low not terrible. It should be a minimum of rpm WOT at your average altitude, but a sweet spot is around WOT at your average cruise altitude. It is just a tad overpitched. Not bad, but could be a bit better to help your overall performance since you have a ground adjustable prop.

If for any reason you don't like it you can put it back. Ian Cooper. Yes that is where the pitch was set originally. We changed to where we are to get a better cruise speed which I am happy with.

It doesn't detract much on take of performance. I just want to know how many revs below maximum should you cruise at to be best for the motor.Remember Me? Forum The Hangar Microlight Discussion help wanted whats the difference between rotax and Results 1 to 9 of 9.

How Do Rotax Engines Work?

Controls the water temperature much better and if not below freezing you do not have to cover the radiator. If the thermostat fails they usually fail in a half open and half closed position. A Gray head with a broken thermostat as above will only require a power reduction to stay at a safe water temperature.

So why did they install the thermostats later? Without a thermostat, the steel cylinders with cool water passing through them could not expand as fast as needed to keep up with the fast expansion of the aluminum pistons. This results in a cold seizure, which is why we use ceramic top pistons.

They deflect the heat from the piston and let it expand much slower. A Blue Head with ceramic topped pistons is very hard to cold seize.

Can have the normal thermostat failure and be ok to get you home safely. And how does this relate to the ? All said, the is far more likely to cold seize than a This is very important on a new or freshly overhauled engine. The Rotax engines use a cast piston that will shrink.

This is why it is really very important to extend the warm up period on overhauled or new engines. On liquid cooled engines you can fly at different RPMs every 5 minutes. Avoid touch and go manuevers. We used to use that chart with a timer on many factory new gray and blue head engines.

The throttle needs to be cracked. How far? The carburetor slides, if watching them, would move up about the thickness of a nickel. Crank the engine. Chokes are not need above 40 degrees. Once started, advance the throttle to RPM.

The steel expands much slower than the aluminum piston, which is why you need. Heating the water is one thing but really the cylinder walls is what counts.In many ways, Austrian manufacturer Rotax's signature two-stroke engines are just like any other two-stroke out there; they work in the same basic way, have all the same basic parts and do all the same things.

But Rotax engines have long been known for their enormous power output relative to weight and displacement. Like most things Austrian and German, the secret is all in its engineering and attention to detail. A two-stroke engine works by using the piston to cover and uncover intake and exhaust ports in the cylinder walls, instead of relying on a camshaft and valvetrain like a four-stroke engine.

Starting at the top of th piston's stroke, an explosion of air and fuel shoves the piston down. As the piston goes down, it uncovers the exhaust port, which releases exhaust gases from the cylinder. Next, the piston uncovers the intake port -- opposite side of the cylinder from the exhaust -- and allows fresh air and fuel to enter the cylinder.

The inertia of escaping exhaust gas sucks air and fuel through the intake port.

Inertia drives the piston back up, covering both ports and compressing the air-fuel mixture against the cylinder head. The spark plug ignites that mixture and the cycle begins again. Rotax engines are known for power an reliability, but the approach Rotax uses seems a bit antithetical to the one used by most two-stroke manufacturers.

Horsepower is a function of torque and engine rpm; if you have more rpm, you need less torque, and vice versa. So, the simplest way to increase horsepower is to run the engine at higher rpm.

In the karting world, Yamaha KTS models typically rev to about 16, rpm and Leopard engines to about 17, rpm. The equivalent Rotax BRP makes the same or more horsepower revving to a comparatively tame 13, rpm. That might seem like a bad thing, but the end result is less engine wear and a flatter, more useable torque curve.

In many ways, the Rotax engine's power valve is the secret to its success. The power valve works something like a VTEC system in a four-stroke engine, altering intake and exhaust valve timing according to rpm. But a two-stroke engine doesn't use valves like a four-stroke engine does; its intake and exhaust valve timing is dictated by the height and position of the intake and exhaust ports.

So the only way to alter timing is to physically change the size of the ports.Eipper Aircraft Quicksilver MX. Jack Hutchinson, under contract to Eipper, was charged with developing a new ultralight. Units delivered, by June Since the Quicksilver MX has progressively replaced the earlier Quicksilver Double-quick and Seaquick types which were all hybrid control like the type E.

The motor fitted until the end of was the twin-cylinder in-line cc Cuyuna R giving 30hp at rpm and fitted with a toothed-belt reduction drive. However, in NovemberEipper Aircraft announced that apart from the Quicksilver E the other models in the range would henceforth be offered with the Bombardier Rotax engine, since the Austrian manufacturer had a production facility in Canada.

Wing and fuselage structures are similar to the Quicksilver. Pitch, yaw and resulting roll control are achieved with control rods running to the elevator and rudder surfaces and linked to a yoke-mounted control wheel-stick combination.

Additional roll control is achieved by wing-mounted spoilerons activated by foot pedals. The spoilerons may be used independently for quick roll rate or simultaneously to create steep descents at low airspeeds. Dual ignition system. Blue anodised aluminium tubing. Eipper present their kit-set Quicksilver on handy vacuum-packed boards. Non-steerable nosewheel. First year built; Single-seat single-engined high-wing mono-plane with unconventional three-axis control conventional three-axis optional.

Wing has unswept leading and trailing edges, and constant chord; cruciform tail. Wing braced from above by king-post and cables, from below by cables; wing profile; single-surface. Undercarriage has three wheels in tricycle formation with additional tailskid; torsion-bar suspension on all wheels. No ground steering. Aluminium-tube framework, with optional pod. Engine mounted below wing driving pusher propeller. On offer with the option of a glass-fibre nosecone with windscreen since Januarythe Quicksilver W can also be fitted, on request, with a kit to convert the control system to conventional, so that the spoilers and elevators are operated by a stick and the rudder through the rudder bar.

This kit is retrofittable. The MX II is a side-by-side two-seater.The Rotax is a KG of Austria for use in ultralight aircraft. Early ca. The Rotax features piston-ported, air-cooled cylinder heads and cylinders, utilizing either a fan or free air for cooling.

Lubrication is by use of pre-mixed fuel and oil. The engine can be equipped with either one or two piston-type float carburetors. The dual-carburetor version uses Bing model 84 carburetors. The single-carburetor version uses a Bing model 54 carburetor. An optional High Altitude Compensation kit is available. The engine's propeller drive is via a Rotax type B gearbox. The standard engine includes a muffler exhaust system with an extra after-muffler as optional.

The standard starter is a recoil start type, with an electric starter optional. An integral alternating current generator producing watts at 12 volts with external rectifier-regulator is optional.

The engine includes an intake air filter and can be fitted with an intake silencer system. The manufacturer acknowledges the design limitations of this engine, warning pilots: [1].
