2010-08-05 · After all, a constant speed propeller is really a fixed pitch while in cruise flight. OK, for all of the purists, it is never really fixed, and in bumps will actually be making constant pitch corrections, but the difference is really negligible for this discussion.

2020-07-01 · Fixed pitch props can, in general, match the pitch range of a constant speed prop from most coarse pitch (cruise) to most fine pitch (climb). So, in general, a constant speed prop won't gain you any extra speed over a fixed pitch prop. The advantages of a constant speed prop are uniformly good performance over the speed range of the airplane, more drag on descent and landing, and, if your plane …

2009-11-19 · IMO, many go with the fixed pitch prop because of the initial expense of the constant speed. I went with the C/S right up front because I knew of all the advantages before hand. I had switched from F/P rentals to C/S rentals a long time ago.

2015-05-09 · fixed pitch vs. constant speed . I am look at purchasing a RV-7 and it has a fixed pitch prop. I have low tail wheel time in a champ but lots of time in a RV-9A. Someone mentioned a CS prop is better because it will help you slow down the airplane and better for low TW time pilots.

2009-02-04 · fixed or constant speed ok guys, new rv-8 builder here, and a&p mech. the question of fixed pitch or constant speed is one that has many pros and cons. from a mechanics point of view a constant speed prop is obviously more cost, more weight and most importantly, more maintenance. you have all the inner workings of the prop and prop governor and not to mention the extra lines available for ...

2010-08-05 · Constant speed VS. fixed pitch Can anyone tell me if there is a sufficient performance difference in an O320 with a constant speed VS a fixed pitch prop (160hp). I realize there will be some difference but is there any emperical data showing the differences.

2016-04-17 · You want the Constant Speed (CS) prop and the 360. Look at the Van's factory airplanes. Other than the RV-12, they all have constant speed props. With over 3,000 hours flying an RV-6 with constant speed hours, the 320 CS will out climb the 360 FP at and below 100 KIAS. From 100 KIAS to about 130 KIAS, they are very close to the same at the same weight.

2010-02-06 · I recently purchased a 'previously loved' IO-360-A1A which was set up for fixed pitch props. It doesn't have the stainless steel (or flexible) oil line, shown below from the Lycoming service bulletin No. 1435 for converting to or from constant speed props. Lycoming wants $500.00 for this part!

2017-01-26 · Constant speed to fixed pitch . There does exist a way to very easily make the change WITHOUT modifying the freeze plugs in the crankshaft, or removing the stainless line that goes back to the governor pad. It DOES require the removal of the governor, and a …

2016-08-01 · While I intend to use a CS prop, the engine comes with the end plug in it for a fixed pitch operation. You have to pop the plug out in order to use it in a constant speed configuration, for the oil to travel the crankshaft to the prop. It has some instructions on how to replug in the future for fixed pitch operation.
