Default Prop for a piped YS .45 on a shrike

Hi guys,

I'm just about finished up with my Shrike 40 and would like to know the correct sized prop for my application. I'm running a YS .45 with a Macs tuned pipe. I use the standard 11 X 7 for everyday flying with a muffler, but would really like to hang this plane way out there on the fast side.

Thanks in adance for your help!

Eric

I would start with a 10x7 or 10x8 APC then try a 9x9 when you get comfortable with the launching... I recall liking the 9.5x8 also... (Cut down 10x8)

You using the 7.5cc or 8.5cc pipe?

Any pics

Fender That post is almost incoherent... Do you mean the one piece black Macs muffler? If you mean pipe- there are different volumes with different results.

hey I have a question, I was watching my combat models f-16 video to do and noticed that he said that the jet flying in the video had a ys 45 with a regular muffler on it. How much more powerfull is the 45 with a tuned pipe vs the stock muffler.

Whoa! Does he say that in the video? The YS-45 on a stock muffler is almost the same performance-wise to the OS-46FX [X(] (I have tested it) The macs pipe is the way the YS was designed to be run... So in a word> Oodles!

I love the YS-45

Is anyone still using the stock 7.5 cc fuel tank? if so how long of flight times do you get since this is a mostly wide open throttle plane.

7.5cc you'll fly about 45 seconds, if you pull back to save fuel 1 min 30 sec.
7.5 ounce 6-8 minutes, depending on how hard you push.
