The plane is a comp arf Extra 300 with a DA 100 and i will be using it for imac this year.

What kind of mufflers? What's the plane weigh? What class will you be flying?

MTK cannisters, Sorry

Go with the 28X10. Your DA with cans will have more than enough umph to swing it but have enough load to keep you from ripping the hell out of it. It works well on the downlines. Put in a throttle curve that will soften the resoponse between 1/2 and 3/4 throttle as you will be spending most of your time at that throttle position.

I see a lot of 3 blades on the 40% planes but I don't see so many on the 35% 100CC planes.

Hi Bobby,

I used the Mejzlik 28x10 with good IMAC results on my DA100 / 35% Extra. The three blade props just aren't as necessary for controlling sound on the 100cc engines with cans. You also lose valuable efficiency compared to the two blade.

You got the Patty ready to go? Still want to come over to your field soon, talk over the contest, and get some flying in.

Chris, the Patty is just about ready. All that left is to mount the radio gear in the correct place to balance. HOPEEEE to fly it this weekend. Yes we need to talk about the contest. Thanks for the input on the prop. I can't wait for the judging school...

Bobby,
I will agree with the 28x10 for the DA100.
Just make sure you have a good throttle to throttle mix to ensure that you stay in the sweat spot for all your mixing and flying.

Consider a 3w carbon 27x11, was my favorite imac prop for DA 100 and cans, pulled extremely hard, great braking, and it was quiet.

How much did your plane weigh?

It was about 27.5-28lbs, and still pulled hard.

I personally would try the 3 blade, generally it will keep your speed more consistent. I found it very easy to rip the 28X10 with my DA100. I ran the 27X10 most of the time.
