Very cool LuckyDuc..
that's just the iinfo I was wondering about!
Anyone have some suggestions on other props to test in this size range?
I don't want to goto a 6 series type prop after reading about over amp issues with the ESC.
I was considering a Prather S220 next after testing the Grim L40x57x3.
Detox likes the Grim L38X55, he also suggested the L38X63.
still has the stock motor ?????????

WHAT?? No, I have only run my gassers at a Lake just off I-70 and Colorado Blvd. near Commerce City. I run my FE's at Wash Park since I live so close. It takes me 3 minutes to get to Wash Park, it's awesome. Do you have those dudes contact info, would be nice to run my FE's with some other dudes this summer here. thanks man,
Jarrett
PM'd you.
Here's three of my Grimracer props. Two props on right have been hardened. I will do a comparison soon.
From left to right L40 X 57, L38 X 55, L38 X 63

Nice looking props. What do you charge?
I posted my initial eagle tree data on the grimracer L40x57 here
How do you harden a prop?
-t
A really sharp prop is thin and easy to bend along the sharp edges so I heat treat. I bake my props at 600 degrees for 2 hours then let them cool slowly over night.

#2. Just do the 600F step after yo work the prop. Still very hard, but you canbend them a little if you really need to.
I took a break from balancing and sharpening my next test prop, a Grimracer L42x66, and decided to run my M445 again.
Apparently my driveline has loosened up a bit and is now broke in. I hit 55mph and it is pulling a lot less amps than prior testing. Data below.
dayuuuum that is fast. I will have to try my m445 tomorrow.
