Ok guys much happier. Got the props in today. 7580 rpms with a 20x8 and 7510 with a 19x10. Also my motor temps went down. I ran the packs down in under 5 minutes to only 7% left in the and the motor was only 110 degrees. I was on that left stick too . Getting ready to check amp draw now.

What prop were you using and what do you have now? 7% of 80% or 7% in the whole pack?

Wood, plastic, or Carbon? Wooh, when I run 3D with 12s 2600, I get 6-6.5 min. Even with mostly WOT flying around I get 5 min. 20x8 prop. I know you run pretty hard, but man that's not good flight time at all.

I think it's the right pilot but maybe the 25-28% size which is 4 3/8 tall vs, the33% which is 5 1/16 tall, what do you think?

Wooden prop. Oh with the 20x8 xoar l am only pulling 2746 watts peak. Apparently the 4330 doesn't like a heavy cf prop as l am pulling less wattage with a wooden 20x8. I have a xoar 19x8 to test out later this week too.

Yeah, I believe it's the 25-28% one.

With my 112 gram apc I got more RPM and more wattage then my 61g xoar... Spool up was noticeably slower though.

The main problem with an APC propeller is that it flexes more than a xoar so while you may get more RPM with an APC prop you will lose power overall, IMO. This is much more apparent with larger props with diameters over 15".

Yeah...I would think the 25-28" Size...but I have never measured the canopy height/width...

Well the 71" slick is 25% so the 25-28% pilot would be the one.

Funny thing....I was talking to Mike Donovan at Aero-Model on Friday about props, as I was considering changing out the Xoar 20X10 PJT gas prop for a lighter Mejzlik or Falcon prop. One thing he told me was to be careful doing hard 3D, I.E. Blenders, Knife edge spins etc, with the lighter carbon props are they are not designed for 3D, but rather for pattern flying. He says he has seen the lighter Mejzlik props break in mid-air, when used for 3D. That would be scary, as throwing a blade at full throttle would, I am sure destroy a plane before you could even get off of the throttle....

And maybe that's where the extra 65 RPMs came from... IMO it wouldn't effect performance to much unless I was seeing significantly less amps/watts which were more. The real deal breaker for me was spool up time of the APC. So I think flexing has some effect but nothing too significant... however, the weight of the prop is what does it in at least for me.
