Cessna 150 Propeller Installation Video

ROTAX CESSNA 150 – UPGRADE YOUR C150 WITH A MODERN ENGINE. Atol Avion has been granted an STC for the installation of the 100 HP Rotax 912 S3 and a constant speed propeller in the Cessna 150 providing the benefits of modern propulsion for one of the world’s most popular aircraft.

Les,There are a few considerations on prop selection. 1) What are you going to be doing with the aircraft? 2) Why are you getting a 3 Bladed Prop? 3) What are you going to be doing down the road.Lets start about Landing Performance. Most guys do not start here. The 3 bladed prop acts like a large air brake when on approach.

We have 2 C-182\'s one with a 3 blade propeller and the other with a 2-blade stock prop. Depending on how you fly, you may find that the 3 blade will help quite a bit on short approaches with tighter corners. The 2-blade 182 lands really fast and uses up more runway than the 3-blade.

I must also point out that full flap landings are not done to reduce wear. Flap selection is done based on runway length and conditions.

When sufficient runway is available the 2 blade lands faster.As far as climb performance you can discuss this till you are blue in the face. Everyone has their preference for make, size and whatnot but at the end of the day, it is all about how much \'pull\' the prop has. Having a larger prop that makes noise and annoys the neighbours may not get you anything other than \'more noise\'. It is best to address those questions to the STC holders to see how the prop actually is set up on the aircraft. Not all are made equal.Although not required by many STC\'s, going from a 2 blade to a 3 blade adds weight and a extra cycle of fatigue to the mount. With a 3 blade prop you now have 1.5 times the movement in the mount even if that movement is 1/3.

I find a lot of guys put a 3 blade on then end up sending us the cracked mount. The STC may not require a beefed up mount but I can tell you that Cessna improved all spares mounts in 1990 by adding reinforcements to the engine Isolator pads. The aircraft may not show signs of vibration more but NDT inspection shows cracking. Keep in mind that Cessna required a structural change to the engine mount on the C-185 when the 3 bladed prop was added.The 3 blade is the way to go if you want to climb and land in those \'remote\' places we all dream about going. The modern 2 blades are really good for speed.
