He bbrown282,

Let us know what the prop does on the GP61.

I'm getting 6900 with a CF Falcon 24 9. I ran a CF Falcon 24 10 yesterday and it gave me 6520. It flew very nice with the 24 10. I would use that for an IMAC setup. Very consistent and smooth up/down lines.

The CF Falcon 24 9 has more static pull and it revs up a little faster. My choice for 3D/hacking around.

What do you guys think of the sound of my GP-61 after 2 gallons? The movie below is the last two flights on a windy day. I am doing some slow, medium, and fast passes. Sorry for the wind sounds across the GoPro and the crappy setup of the headband. Most of the footage is pointing at the sky and not the plane, but the sound is what I what the experts to hear.

STIHL High Performance oil for first two gallons (so far) This is a blend of synthetic and mineral. 32:1 for first and 38:1 for second gallon. 89 octane for both.
Plan on going to the Ultra High Performance oil from STIHL which is full synthetic @ 40:1 more? 50:1 92 octane
Jtech Wrap around Pitts style muffler two down pipes.
Tech Aero Designs Ultra IBEC powered by PowerSafe AR9110 receiver on two 2S lipos

The real question is lean more or wait for 40:1 mix with 92 octane gas on next gallon.

I have been slightly leaning out the LOW ever since I got into the second gallon. So little by little over the past 7 flights. Also just barely leaned out the High. As you can hear popping and gurgling at the mid stick.
