Mine has a Motrolfly 4315 530 KV. I have a TriFlyer 50" GBR 50 and that has the 500KV version which is amazing also.

Motrolfly is the best on the market. You can see the quality of his winds and how tightly and perfectly they are wound. You can send them to Ken to rebuild or even change the kV for a fee of course. I have 8 or so of his motors from subsonicplanes.com. You didn't think twice about spending $300 on a glow motor. Don't cheap out on the eMotors either. Good motors will reward you with years of service. I have 5 of the 4315's in kV from 500-580kV. For a 6lb 60 size I run the 4315-530kV and it's great power. With a 4Ah 6S HK Graphene on a 17x8e prop, I get well over 5 minute flights.
For a 5lb 50 size, I bump it to 560-580kV and 14x7e and a 3Ah 6S.

You’re right, Motroflys are pricey. Know what’s more expensive? Buying a bad motor. Not saying anything against your suggestions but once I’ve owned a few Motroflys I’m now a snob, on the bigger stuff that’s all I’m buying. Just not worth getting it wrong to me.

I have a motorlfly 4315 on 6 s but I consider it a minimal setup. I like Ef lite 60 power.

Trying this one on a bro's recommendation.
I seen a thread awhile back naming names of which chinese companys build the majority of the e motors.
I was surprised that there are just a few factorys doing a majority of the import stuff.
Motrofly might be in my future,but i havent been burned by a shitty kung fu motor "yet"

Motrofly sounds like the answer. Thanks. I was toying with the idea of going electric on the Mojo60 instead of the DLE20 I already have, but I got a Four Star 120 kit and am undecided on what engine to put on it. If I use the DLE20, I will need another motor for the Mojo. Also have a DLE35, but that may be too much for the 4*.

All is kind of moot now, as I finally found a decent deal on a cabinet saw nearby. Been waiting for 2-3 years on one to pop up. If I get it, that will blow my budget.

Thanks. Those Motroflys are pricey! I've heard some good things about the BadAss motors. Wondering if this one would work?
BadAss 3530-470 Brushless Motor (innov8tivedesigns.com). It's a little smaller than the 43 series but will put out 1300 watts on 6S with a 16x7 prop.

Or maybe this one?
BadAss 4520-540Kv Brushless Motor (innov8tivedesigns.com)
I've got the 3520 560kv BadAss on my GBR50; running a 15x6 on 6S. Plane weighs right at 5lbs ready to fly; very good power. However, I've snapped 1 motor shaft, possibly due to gyroscopic effects of knife edge spins/crankshafts, etc. Possibly also just a fluke. Replaced shaft; couple dozen flights since then no problems.

Trying this one on a bro's recommendation.
Got this one on my EF 60" Edge fatty; that plane weighs about 6lbs RTF and is ballistic on a 16x7. Highly recommend this motor in that size/weight plane :)

What the guys said about Motrolfly is right on.. Worry free flying. I'm running 7 in various sizes (plus a nice stash for the future). I've never had even a hint of a problem with any of them. I like that I can bolt the prop on, have phenomenal performance, and never have to think about it again - just go fly.

Well, the table saw deal fell through, so I'm back to looking for the stuffings for the Mojo60. Buying parts isn't as easy as it used to be. One store has the motor, but not the ESC. Another has motor and ESC, but no props. Another has props but no servos. Seems like there is no one stop shop to get everything you need anymore.

Kind of got shafted on the table saw. 4 year old Grizzly 1023RL, looked to be in great condition. Guy was asking $1100 for it. Worked to set up a time I could go look at it, lined up a buddy with a trailer to help move it. The night before I was supposed to go, he messages me saying, "Oh, the price is wrong. I'm now asking $1800 since they're $2300 new". I'm sure he went to the website and saw the price increase and figured he could get more from it. It was $1500 or less 4 years ago when he bought it. I guess I can't fault him for trying to get the most he can out of it, but I just feel like he wasn't showing much integrity..

Joebob, I can't speak to the Potenza, Never even seen one.
On the battery, I would probably split the 6S into a 3S pair in series, if you have room on the fuse. I have mine on a single 6S and it takes a large stack of washers to offset the lateral balance of having all the battery on one side. You definitely notice it on axial rolls. As far as size, I run 4000 or 4Ah and get well over 5 minutes on a MoAss and Primo 60. Now these are good batteries (Graphene) and weigh almost as much as some makers 5000. Running a Castle 100 on the MoAss and a Talon 90 on the Primo.

Cool. Thanks. I was wondering about the effect of having a huge pack on one side. I guess it would also give me a little more flexibility to have 2 3S packs since I could use them in other planes easier. I went ahead and got the Potenza just to experiment with.

Yeah, do the 2 3S packs in series. That has worked well for me on 40 and 60 size systems. On the 60 I am running 2 3S 3300's.

What is your actual amp draw? 65ish?.im assuming youre propped to somewhere around 1500 watts?
Seems like you would have plenty of headroom with a 100 amp esc.i have another one of the dualskys im planning to use on a jeide built sbach.i was hoping to use an phoenix ice 75

The MoAss had that 100A ESC on it when I bought it from Gatorb8 when he went out. The Scorpion motor it had chucked the magnets and wrecked the windings, so I replaced with Motrolfly.
Since I don't really care about static amps on the ground, and the Talon doesn't have data logging, I just know it's under 90. LOL The whole system (motor, battery, and ESC) comes down no more than ballsack warm.
