New rpm numbers, some level flight mph, and digital scale pulls.

SY 16 X 8
Top end @ 8900 rpm ( that up 150 rpm from last flying day )
Average MPH of left and right passes is 82 mph.
Pull in pounds on a digital fish scale is 13 lbs.4 oz.

APC 17 X 6
Top end @ 9450 rpm ( up 50 rpm from last flying day )
Average MPH of left and right passes is 83 mph.
Pull in pounds on a digital fish scale is 13 lbs. 13 oz.

Verticle is a tick better with the APC, but knife edge is better with the SY.

Just remember, these are two different size props.
I wish I had a APC 16 X 8 to test head to head against the SY.
Also as a comparison, I had the OS Max 1.60FX on this same plane with a Master Airscrew 18 X 6 and it was pulling 97mph in level passes.

I like the SY and am keeping it on my 26.
i dont want to steal your thunder but i as well flew today after work. 1/2 gallon 6 flights and the 50 gets better and better. idles like a sewing machine. i aquired a new in box wagstaff and it requires a 50 cc. take one guess what motor i am putting in it? funny thing is i havent even wanted to maiden my laser as i am having too much fun with the extra...
