Anyone know how these two motors compare and what would be the best for 3DHS "41 Edge 540 application? Anyone have any experience with the two?

Thank you!

The 81g Turnigy Park 480 is probably good for 250W, the 88g NTM might be okay for a bit more (?270W). Don't believe the ridiculous amp/watts limits posted by HobbyKing unless you want to use your motors as immersion heaters.

That plane is said to weigh about 2lb or a bit more... so you probably want around 300W (150W/lb) for fully aerobatic performance... either of those motors will be okay if you are willing to push 'em hard. I realize that WOT might be used sparingly, but personally I'd go for a 100g motor which could do 300W without turning a hair.

A 105g Dualsky XM3536-8 (~990Kv) with an 11x7 or 12x6 on 3s might do you well.

The Turnigy Park480 is realistically rated and has good efficiency (my test data here). It is very similar to the E-Flite Park 480.

If the NTM Prop Drive's dyno test is accurate then it is a poor performer. I would avoid it.

The Park480 should draw about 300W with a 12x6 prop. Though overloaded at that power level, full throttle is rarely used in 3D so it should be OK.

If you want more power and don't mind a bit of extra weight, a 100~120g motor would be preferable. The Scorpion 3014-1030 with 11x5.5 prop would be my choice, but it is rather expensive. Other alternatives include the KD 36-16M, Turnigy L3015A-1000, and Turnigy Aerodrive SK3 - 3536-1050kv (currently out of stock; hopefully not for long!).

Not particularly, but I've tested several Dualskys and have yet to find a bad one. I did test this 3536-8 motor extensively and found it was pretty darned good.

I'm using that park 480 with a 12x6 apc on an 3dhs 41" edge. it's 357 watts 30 amps peak. 6:00 minutes of 3d flying and it comes down cool.

I have it connected to a mystery brand 40 amp esc.

i did elongate the holes on the motor mount just a tad to fit the holes on the Edge 540.

That is one heck of a battery pack if it can manage 11.9v @ 30A.... in-flight you must have lower voltage and amp draw.... so Bruce's 300W estimate seems more realistic.

I can post pictures if you need evidence. I was to lazy to type the numbers out to I just took pictures of the watts up meter connected to the plane.

The batteries are 2 year old Hobbyking zipply 20C 2200mah 3s fresh off the charge.

if you can use a 10x6 prop max this motor is a killer in my leader 480 putting out over 500 watts with a 3 cell setup and the 10x6 prop

1400 kvt is to high for a 3d airplane application. you need a big wide prop with shallow pitch to keep air flowing over the control surfaces.
