    Is the APC 17x8N a good prop for the 26 on a tuned pipe?

    Thanks

    so far - and I have used my setup on the Showtime and Funtanas, the 18x6 props which spin easily seem best - but that might be a good prop an a fast sporty setup - say a scale racer where you want it to really move-or if you like old style pattern where it really cooks - should be great .

    Status: offline     		The APC prop 18x8N spins in excess of 8000 rpm, so I wold use at least a 10"pitch if you are after speed. (16x12 or 17x11)
    For thrust, and power reserve (needed for quick spool-up in 3D) the 18x6 is best.
    For normal sports, use 18x8 or 18x10
    APC does not provide the best thrust in these sizes. In my tests, it performed worst of all
    (compared to Menz- and clones, Mejzlik, Zinger)

    Status: offline     		I'm using the 26 on a CMP Giles 202. I have an 18x6 menz, an 18x6 Pro Zinger, an 18x6 Top Flight or the APC 17x8. I guess for starters, I'm looking for more pattern speed than 3D. Also, the plane is a little overweight, so I thought the 8" pitch would help with keeping speed up a bit on final.

    Any more thoughts?

    Thanks

    Status: offline     		the pitch being lower is actually better for landing- keep revs up and then control final speed with throttle -NOT elevator

    APC is very heavy spooling up much slower than CF or wooden props - not good for 3D. I run 18x6 Mejzlik on Powerline Hobbies Edge 540, and this is the happiest prop for this plane.

    Status: offline     		This being my first gas engine, I see all the plastic pustrods. Is my metal pushrod going to be a problem? I plan on starting it for the first time tonight. Should I just see what happens or go ahead and find a plastic pushrod. My next question would be where to get one.

    I use a combination. Inside both ends of 10-15 inch golden rod I screwed in a short piece (2 - 1.5 inch) of metal threaded rod. The golden rod is running inside the plastic sleve but both loose ends (without the sleve) do not bend because of the metal inserts. This way I have thread on both ends for clevis to put on, and the part of golden rod between sleve and the servo horn (or throttle arm) and th sleve doesn't bend for crisp throttle control. And what is important, the plastic rod doesn't melt from the engine heat.

    You can see the throttle setup on my MVVS 1.6 in Powerline Hobbies Edge below
