[NSRCA-discussion] Yet another prop question for OS users.

[DaveL322 at comcast.net]

Colin,

Been awhile since I ran the 15.5x12x4 - not my favorite because it tended to load the motor heavily in verticals, but quiet, decent speed, and good brakes.  Probably close to the 18x10PN for load (on the ground - the 10PN will unload better in the air and is much more efficient).

Yes, in general the sensitivity of the setup will increase with increased load.

Great info...thanks Dave. 

Is also safe to assume that as the load increases the set-up becomes more sensitive?

Where would the 15.5x12.5x4 fit in?

Colin.

Colin,

In order of lightest load to heaviest load -
15x11x4
18x10 (wide chord at hub, narrow at tip)
15.75x10x3
18x10PN
18.1x10.1

The 3 blade and 18.1 are the quietest props and have the best braking.  The 15x11x4 has the least amount of thrust/vertical.

Regards,

DL

All/OS users

I'm still looking for the best compramise for speed control using the OS140/Aeroslave pipe and an "almost" wide body aircraft like the Temptation. Has anyone tried the new 18.1x10.1? How does it compare to the 18x10, 18x10pn, DL re-pitched 3 blades and the old 4 blades?

I would like to try a new (currently using 15x11x4) approach but would prefer not to buy 3 new props. 

Colin.
