Love my large NTM motors. Should swing whatever you want. Still from HK but good stuff. Make sure you order the accessory pack too as it does not come with the mount or prop adapter. Never figured out why they do that on this series.

I found a Turnigy C5065-400KV motor I was going to use in my Senior Telemaster and it matches the specs on that Eflite Power 60. I may stick it on the watt meter with my 18x10 prop and 6s and see what it does.
I was looking at that very motor.
Here's the one I had for the Telemaster that I just put on the Stingray. Yep, it sucks too! It spins but is horribly out of balance. I had to use an unbalanced prop and radially balance the whole assembly. It'll work to get it in the air but i think I'm still on the lookout for a better quality motor. I may just be done with HK motors...
OK, I went with this motor. It's shipping from the USA, I got a helpful employee on the phone on the second ring, and I was told that the motor will be perfectly balanced out of the box and if there are any problems with bearings or balance, they do all the warranty work there...

It's only about $35 more than the Turnigy NTM 50-60 also!

Where did you buy it?
I'm withdrawing the question. LOL!

LOL, sounds like something I'd do ha!
I was told this is Scorpion's "budget" line of motors. Being told in not so many words that if it's not perfect when I get it to send it back and they'll get it taken care of is what does it for me now. I'd be happy buying more HK motors if it wasn't a hassle to return if the item wasn't perfect. BUT, my last order from the USA warehouse took one week before it was even shipped. And if you have an RMA to file, it takes them a month before they exchange or credit your account. To avoid this hassle, the extra $35 or so was so worth it!!!
If I had been through what you just went through, I would feel the same way.
Your sympathy is appreciated! I've had good luck with the smaller HK motors but first two large ones were duds.
Waiting for the new motor to come in. Since I can't balance the plane without it, I did the wheel pants...
They came in pieces.
They are to be taped and thin CA'd along the seam.
Then you have to cut the hole out for the wheel. I drilled a hole then used a drum sander on my dremmel.
It's reinforced with a piece of light ply epoxied in place with blind nuts behind it.
One side done.

Looks like the maiden flight will be tomorrow! It's balanced with 6s 5000mAh with no added weight, front or back!
New motor is installed. No vibes!
All that's left is to Loktite all the metal screws, set the control throws, install with windscreen and mount the rx!
I'll get a shot of the whole plane in a bit.

It came in a 10.5 lbs ready to fly which is about 1.5lbs lighter than I expected.
These pics are without the windscreen, so it looks kinda weird.
1600 WATTS!!!

OK, for any of you who haven't completely abandoned this thread, here's the maiden flight from today!
Thanks, Freaky, I appreciate that! The maiden went well. It was way out of trim and pretty nose heavy. There's a slight twist in the wing so it kept wanting to bank left. The ESC kept getting way too hot but it's totally enclosed with no ventilation. It does look like I need to prop down a bit. I used an 18x10 so I'll try an 18x6 or a 17x10 next and see if that cools of the ESC a bit. If not, I'll mount the ESC outside probably up against the firewall somehow or on the inside of one of the cowl cheeks.

Great job BM! That's a very elegant plane on the ground and in the air!
Congratulations.
Congratulations.
Thanks, once I get everything straightened out I'll stick my Mobius on it and get some aerial footage.

That looks like the maiden went spectacularly! It's always a nice payoff when a plane flies that well on the maiden. Congrats!!
