On my 100cc AW YAK I ran the Mejzlik 28 X 10 Carbon Fiber prop. I liked it much better than the 27 X 10. It really slowed the downlines and landings, and smoothed out the plane everywhere.

Run the 27x10 since you got it.

I think a 27X10 is what you would want to use.

I used a CHP 28.5 x 8

It really slowed down for landings and downlines... in fact.. it never went fast!!! he he he he

What plane is it for and how much does the plane weigh; also is the planes main purpose imac, freestyle or a mix?

Freestyle = 27 x 10
IMAC = 28 x 10
IMHO

It depends on the plane and the planes weight



freestyle and imac 27x10th most likely

light imac plane 28x10

heavy imac plane 27x10 maybe 26x12

but theres a ton of variable that have to be considered

Dave Johnson SWEARS by the mejz 28X10 for all types of flying. I have one and flew one and it is a good prop for IMAC - spools up too slow for 3D, though. I had been using the mejz 27X10 for the longest time with good success, then I won a Xoar 27X10 at an IMAC contest. Gave it a try and hated it. It spooled up a little bit faster for 3D, but didn't bite very well or accelerate out of a hover very well.
I am now flying a mejz 27X10TH and I am LOVING it. Spools up fast and bites hard and lets the 100 spin a little faster. Haven't tached it, but it sounds like it is spinning faster by a hundred R's or so.
Of course, it is bolted to a 25-1/2 pound airframe so it doesn't have to do much work but the other props were run on a plane equally as light or lighter.
IMO if it is going to be a heavy plane, like over 27.5-28, I'd suggest the 28X10 just because you're gonna need it, and spool up ain't all that important if the plane's too heavy to react to it.

I have to disagree. I used all these props on a qq 102 gen 4 at 27# 7 oz plane and a 28.5# H9 260 and 2 QQ pythons at 27 and 29.5# and the 28 10 lags. In a heavier plane the 28 10 shouldn't be your prop. I used the 27 10 th on it and the prop was really good prob the best but 27# isnt real a heavy plane. Tho on the heavier python the 28 10 felt better even with the slower up lines. all at ~ 1000 Asl . The most gas burned was 24g with the gen 4 yak with only a couple gallons per on the others
