no , I'm not looking for that much power. They recommend 500 watts and the 25 does this BUT it all depends on the power source and prop choice to get to that number. If I don't prop right then I won't achieve those numbers. With the 32 I think it gives more room to work with because of the range of 500 - 770 watts give or take. I'd like to use the 4s 5000mah 20c lipos that I already have. What prop should I use on the 4s to get over the 500 watts I need without going huge on the ESC? 11" or 12" props but what pitch? Or would it be better if I go 3s for better numbers and keeping the size of the esc to good size like 60A?

For me, I like 4S or bigger for anything using over a .15 sized motor.
Cause your gonna need less current to produce 500 Watts.

Over 3S and you want a switching BEC inside the ESC or external BEC that is switching or it heats up.
If I plug in some #'s using the 32 motor and a 4S into this program:
http://www.adamone.rchomepage.com/calc_motor.htm
13x6.5 prop pulls just over 500W
12x8 prop is just under 500W
These #'s assume exactly 770Kv (I've found often motors will be a bit higher)
and 3.7V per cell (it will be that towards the end of the flight).
Your still pulling over 60A at full wide open throttle according to the calculator.
Maybe someone else can run the #'s to see if I'm doing this right.

Super

I am totally happy with my Monster Power 46 on 4 cells in my 5 1/2 pound Tango. The motor is very well built and attractive for lack of a better word. The blue anodized spinner is super good looking. 800 watts with a 13x6 powers the Tango well with good pull-out from hover! I am very pleased with HobbyPartz as well!

This is a 46 size plane with an oversized motor but there is footage of the Monster power 60 in action in the end of the video. Once again, oversized motor but I'm not pulling nearly as much wattage as the motor is capable of:

Fyi Hobbypartz has all the monster power size motors back in stock. I just ordered a 32 and 46 for some Electric conversions.
These those sizes seem to sell out fast.

Just had initial flights on a Phoenix Extra 300S ARF, 57.5" WS, Monster 60, Mystery 80A and Blue lipo 3300mah, 30C, 13X9 APC. The Phoenix Extra is 46 size but at 6lb I opted for the 60 and am glad I did as performance is spectacular. Limited my flights to 7-8 min so far using only 2100 mah so 10 min flights are possible.
I might add the Phoenix lineup are very complete quality ARFs. Next one will be the Extra 330S, 63" WS.

Monster 60 will take 5 - 7 cells, I'm using 5s in this plane and it's plenty.

FYI I'm using a MonsterPower 32 in a .40 size glow trainer. With a 4S 4900 mah, 12X6 prop and 60 amp ESC I am getting a good 740 watts. Provides plenty of power for this 5 lbs trainer.

I just finished up a CMP Giles .50 with the MP60 on 10s 2200 I'm getting 1800watts on a 12x6 prop, AUW is 6.7lbs. Flies awesome, hope the motor holds up at that power level.

I like it so much I ordered up the CMP 1.40 Giles and have a MP160 on it. It's ready for it's maiden flight as soon as weather and time align.

I ran up the 160 yesterday on a 16x10 prop, 10s 4400's, motocalc was saying I should see ~60amps with that setup but I was under 40amps? It was pulling pretty good but I picked up an 18x12 today which should be closer to the kind of power I wanted.

any idea on what the watt's are that you are pulling. let me know how the flight went. the dave patrick ultimate bipe 120. auw should be around 12 pounds. would like to get around 2,500 watts to be able to pull out of a hover with good athority.
