Two AXIs or two Scorpeans? Which to buy?

I'm getting ready to purchase two new motors for a twin.

The consensus seems to be that the Scorpean 3026/12 (KV 710) is a comparable to the AXI 2826/12 (KV 730).

I have always used AXIs and have never had a problem. Happy with them!

But:

Buying two Scorpenas instead of AXIs will save me about $75.00.

Which would you buy? And why (other than price)?

thats my vote

you in the usa? or outside usa? not sure that matters but ample places to get scorps here in the states and heaps of discussion and replies buy distributors and vendors of scorpions on rcg. save money and chat with a bunch of fellow flyers in the rcg community over motors sounds like a good combo

since you asked why??
lucien helped me spec out my first electric motor. figured he gave me the time, ill buy it. he helped teach me how to use scorpion calc on the phone. well he can keep getting my money for taking time to help me.

I'm sure Lucien is a neat guy, but what about the motors?

Gee pmackenziek, I did not ask about Turnigy. I asked about AXIs vs Scorpean.
Please!

It was just a suggestion

I mention the Turnigy as a substitute for the 2826/12 because I recently tried both it in a C/L plane and could not tell the difference in flight. The Turnigy did draw a tiny bit more current at the same RPM than the AXI. (About 5% more)

I have lots af AXI motors, a couple of Skorpions. Both are great motors.

I have an HK2221-8 in an HK450 heli.
I use a 2215-18 in an electric sailplane. That one is being pushed quite hard at 25 amps on 3S. Too hard for more than about 30 seconds of run time.

AXI motors I have used ever since they came out with the 2820/10 back in 2001.

The 2826 are great motors.

I have to say,
I love AXI motors. I had a issue once and they sent me a free repair part. So I give them a thumbs up. Have not every tried a scorpion, But oly hear good things about them. I have done many HK motors and they are OK, but then again they are a bargin for the price.

Seeing as you are building a twin. It probably is not a cheap model. That said perhaps you want to stick with somehting a little nicer.

If money is no object I would buy the AXI. But that said, for most of us it is important. Next time I need a quality motor I am going to try a Scorpion. Just so I can have a reference point.

I mainly have Scorpions (just one AXI). I really don't think there is much difference in performance between the two (one way or the other)

Also remember that you need to account for all the hardware you need. That was the original reason I went with the Scorpion--the AXI really came bare bones.

However if you want to pay the extra money for the AXI, I am sure it will also perform well too.

Alan Hahn, I am also concerned about how the motor performs overtime. Just a couple of flights doesn't tell much. A Scorpion might perform just as well as an AXI for a few flights, but how will it hold up overtime? That's what I really want to know.
Anybody?

highflyer, when money really and truely becomes an issue is when a motor goes south with your money. And I have yet to have an AXI do that. But I would still like to CONSIDER the Scorpions---$$$$$

highflyler, you buy a Scorpion and then let me know how your "...reference point..." comes out.
Just kidding!
Here's what I'm gonna do--unless I get more useful information than what I have so far:
I'm going to put my two AXI 2628/12s in the twin.
Then I am going to buy one 3026 Scorpion (which is supposted to be comparable to the AXI 2628/12 and put it in one of my singles that I have been flying on an AXI 2628/12--"...just so I can have a reference point."

I have a Scorpion 4025 installed in a 62" Lazy Ace. It spins an 18x8 prop about 6000 rpm.
With 9 A123 cells I get 6-7 minute flights. Maximum watts is about 1200 at take off and I cut back to 80% power for the flight.
I have flown it about 100 times over the last 2 years. The bearing seems to still be as tight as new. After a bad landing I had to disassemble the motor and clean the dirt out. It didn't seem to hurt it any.

i have been flying a 2215-18 on 3s with an apc e 10x5 in a pau/bme mini yak since march. its not silly powered but it flies as i want it to. up close and slow

i have a 3020-890 on 3s using apc e 13x8 and then use 4s with a 12x6 on my 3dhs velox since april

i recently transplanted the 3020 into a reichard 90" e sail plane with a 13x7 it can hover it if i want to and sky rocket it at 60 ish degree ups till i cant see it.
ordering another 3020-890 to go into the velox since i moved the old one

i only fly weekends and fly the velox 3 weekends and the mini yak 1 day of the 4th weekend. i average 4-5 flights per day
so i would feal comfortable in saying i have 50 or so flights on the first 3020-890. it is still going strong. but then i follow recommended oil procedures i read on the scorpion website

i have the heli motor 2221-8 in a 450 heli. i started with a sonix motor then a turnigy motor then went to the scorpion motor. i think im getting an extra minute flight times on my 2200 packs with it. its also much quieter then the sonix and turnigy motor

hope this helps

if longetivity is a concern. maybe the 50 percent off no questions asked 2 year warranty might come into play? atleast i think that is the warranty if purchased from an authorized distributer
