Prop searching is a never ending thing. Not sure if you have already but DA might have a good starting point for keeping the "noise" down,,, try giving them a call.

Didn’t think to call them directly. Will try that tomorrow.

The management of the throttle stick coupled with a 29x12 N or S works great. Proper throttle management is what you should be looking at.

Agreed. Throttle management is key. Having started this IMAC journey with an electric plane, you definitely get practice is going easy on the throttle. Otherwise, you have VERY short flights.

On my 91" Extra (w/DA70), I rarely get much above half throttle. I don't even go to full throttle on the up lines. Even then I swapped out the recommended 24x9 for a Falcon 24x10. The 24x9 was getting up near 7400 rpm on the ground and ripping. The 24x10 backed off the rpms to under 7000, and it quieted down a bit.

My DA200 arrived last night -- such a beautiful engine! I was surprised it didn't have its own box like the DA70 does. I didn't expect the motor in bubblewrap and foam peanuts.

I use a 29x12, not an N and not the evo.
I used a 28.5x12 in the past, but thought it was too fast and it did not have as much pull on the vertical.

Works good for me and will only rip on full throttle horizontal flight.

I have the same results as TONY: "Works good for me and will only rip on full throttle horizontal flight"
except I get great pull on up-lines, using a 30 x13 EVO LF Mejzlik 2 blade.
However, critical, and I mean critical, is the throttle control/management. Half throttle or less during horizontal flight, maybe 3/4 stick on UPLINES and full throttle on Up-lines with 2 elements on the up

Not fair!! He did not ask about 2 blades...
But i also use a 30x13 2 blade during the hot summer months. But it is much more difficult to handle the prop rip.

Falcon 29x12x3 also works well, but like others have said....ya still need to manage the throttle to keep it from ripping. Very quiet until then though!
