I'm with ya on the CNC moulds...I would like that 8x12 fixed that is in the pic. With the motor I have coming and the new Monster 1.1 bet I could bust 250 with it easy.
Learned alot from that last build this one should go smoother and faster...problem is...getting ready to go visit family in the States which is going to slow the build down quite a bit!
Canada Post says the Monster should be at my house tomorrow....

only diameter and pitch are not enough to describe a prop, you can make a prop with same diameter and pitch very, very different.
thre is needed more than only the prop diameter for a usable layout for a special reason.
minimum additional are needed:
wished round about input power level and rpm-level at working point and targeted speed, the main data of model (wingspan, area, weight, airfoil, used battery)

Mopar - I'll be in the Elkton, Maryland area. My boy is graduating from Parris Island (Marine Corp Boot Camp) so I will be making a couple of trips down that way to see him and I plan on going to Vic's Speed event in NC while 'm down there as well.
Should be a fun month...leaving here Friday.

Sorry to hijack your thread here arcticflyer...
P in: 4000-5000W
vMax: 100-120 m/s
Wing Span: 1300mm
Target weight: 2200g
used battery?: 8/9/10S, ~2200-3000 Mah ?
I have read all the java prop theory and understand what you're saying. However I also know a 7" prop is a good starting point for this sized model. I never specified a pitch

New Motor for Testing
The 22/60/1E arrived from across the pond...it is a 36mm motor that is 90mm long
The KV on this motor as tested by PeterM is right around 1400 and according to all his prop testing data it is quite a beast
Due to the length of the motor and Mega's stiff wires (hate them) I had to make them into little pig tails by winding them around a pen (carefully I might add).
As soon as I get a few flights in with the new motor mount in the Monster 1.1 and get that airframe completely dialed in, this motor is going in.
It will be tested using props that Marcus is making for me 7.6x12.5's and at 6 to 7S should put the Monster into orbit
With that said the next motor will be one of Steve's 1518 or 1521's with a KV that is better for super sonic than the high kv 1515 that I have now. Will say this...that Neu 1515/1y was burried in a field (8 inches). Then later down the road came out of the front of a plane at over 200, sailed through the air for over 50yards, hit the field....and still runs!!! Great product Steve!

New Motor for Testing II
You'll enjoy your 22/60/1E!
I've just bolted mine into a Parkzone Stryker Q: http://www.rcgroups.com/forums/showp...&postcount=193
I've also just started static testing an outrunner with folding blades and have been impressed to date:
RFM Spinner 38mm
Koch 9.8x17 Blades
ICE HV 160
Scorpion HK4525-520 Ultimate
16,525 rpm or a pitch speed of 266 mph
19,057 rpm or a pitch speed of 307 mph.....
and it has the capacity to run more pitch or diameter if need be.
