The Xera 4020/2y-1000 motor has higher power capability than the Scorpion 4025-1100. The resistance is identical and the Io is lower, so it will run a bit cooler at the same power or run the same temperature at more power. I don't list power figures for my motors since they depend on cell count, and motor rpm (throttle percentage). The Xera 4025 on the other hand would be a replacement for a theoretical Scorpion 4030 motor.

I have a few of Xera 4020/2y-1000 in stock, just send me a PM and I can help you out.

My friend has L500 with scorpion 4020-1390kV @ 12t , fully open Jive 80HV, and flies mild 3D for 6minutes 3900mAh eaten from batt. Lot of headspeed and power. Dont understand why need a bigger motor like 4025.

flying without padles is better , but be sure to get electronic ones

Hi All,
The Xera 4020/2y-1000 motor has higher power capability than the Scorpion 4025-1100.
Oh yeah. That would be awesome. I fly the Scorpion 4025-1100 now and am happy with it, but my X-Eras in my 10S Logo 600 and 8S VBar Trex 600E run cooler and have awesome power.

Give the X-Era 4020 a try and let us know what you think. You won't be disappointed!

Keep 'em flying.

Quote"But you don't want a Xera 4020 in a L500 because
it's power (watt) rating is well below the Scorpion 4020
Get the Xera 4025 for sure...End Quote

Jafa,

Where are you getting your info?

I know the X Era 4025 motor is more powerful than the Scorpion 4025 series. It has the power of Scorpion 4035, maybe more. It weighs 80 something more grams (from memory,could be wrong) than the Scorpion 4020

A Logo 500 with a motor more powerful than the Scorpion 4025, ie the X Era 4025 would be absolutely ballistic...Very cool but I dont sure dont need that much much power.

Im hoping that an X Era 4020 will be around the same power level as a Scorpion 4025 with the X Era efficiency


CNC Addict, I PM'd you. Im interested in your motors

Actually the Xera 4030 is the equivalent of the Scorpion 4035 and from reports the Scorpion has a slight edge on power. I'm running the Xera 4030 in my Logo 600. Great motor IMO and very efficient. My only minor complaint is that I wish it was louder. It was very hard to hear over all the nitro birds at IRCHA. The Scorpions have more of a turbine type whine to them which could be heard more. I know that's an extreme case there. How often do you have 1/4 mile of 90s flying to either side of you?

There are two meanings by "power". One is the amount of headspeed drop during maneuvers. If that is the case, then the fix would be a change in gearing or governor setup. It's possible to make a setup that INCREASES in headspeed during hard 3D, but that doesn't have any correlation to how efficient the motor is, or what the power rating is. It's all about the setup...the battery/gearing/motor/governor gain are all factors.

The Esprit Model site details the motor's max power consumption

Scorpion 4020-1100 1640 watts
Xera 4020/2Y 1000kv 1300 watts

If the Xera was 100% efficient
The Scorpion could run at 79% efficiency
and still have similar power to the Xera

The Xera 4020 will work and is a nice motor
But if you want a L500 to go hard
get the Xera 4025 and forget about the motor weight

Only one of the Xera 4025 motors is rated higher than the Scorpion 4025

Scorpion 4025-630 2520W
Scorpion 4025-740 2450W
Scorpion 4025-890 2380W
Scorpion 4025-1100 2200W

Xera 4025/2Y 2600W This motor looks like a power house for sure
Xera 4025/2.5Y 2100W Likely to be a good performer
Xera 4025/3Y 1800W I would not be keen to try this one

I think it's ridiculous to suggest that the Xera 4025
has the same or more power than the Scorpion 4035
The Xera 4025 range consumes up to 50% less power than the Scorpion 4035 range

Scorpion 4035-500 3500W
Scorpion 4035-560 4200W
Scorpion 4035-630 4200W

Hmmm, You can read my comments above on motor power ratings. I never gave Esprit any power numbers, so comparing those figures has no merit.

I am in complete agreement with CNC. There is no industry standard method that manufacturers incorporate to rate their motors as far as power in watts. I've run 28mm inrunners in S400 class pylon racers which were "rated" at 300 watts, at nearly 700 watts on high current 3S power setups. IMHO, it is not good practice to judge a motor purely on the manufacture's rated specifications.

It comes down to how efficiently a motor can generate such watt figures without overheating or breaking down.

After several of you guys try out the new Xera 4020-1100 let me know how it compares to the Scorpion 4025-1100 (assuming you've flown that too) in power, battery consumption and post flight temps.

I needed a great motor for my L500 flybar'd last spring and since the new Xera 4020-1100 wasn't available yet I chose the Scorp 4025-1100 (on 15t) My L500 is BALLISTIC.

Now I'm keeping my E550 Raptor (since I couldn't sell it) and trying to make it fly closer to how my Logo 500 flybar'd flies.

I can't decide if I should get an identical Scorp 4025, a Scorp 4020 or now the Xera 4020-1100 for it. I plan to fly 6s only.

Thanks,

Dave

Jafa, those numbers are nice but seeing is believing. Ive flown an Xera 4025 and Scorpion 4035's, both had loads of power. Now, blades and batteries might have been responsible for the difference I felt. There was no scientific process occuring here..Just me klutzing around the flying field.

Hey guys, I kinda decided against getting a Scorpion for my Logo 500 (planned for later on) as I had bearing problems with my 450. Now I suppose I could order a Scorpion motor and get ceramic bearings for it like the 450 but is there a motor which will fit the Logo that you won't have to replace the bearings every 200-300 flights?


I noticed the hacker seems to have quite small bearings, I always thought the larger ones (oversized) last longer but maybe I am wrong...

I and others found the ceramics did not last any longer than the standard ones.

The thing is heat is a problem for these bearings.

Now when i say i needed to replace them its cause i pulled them out and they felt a bit rough, not cause the motor was noisy etc.

I bet you could pull any motor apart after a few hundred flights on a high powered helicopters and it would not feel 100% smooth.

I think it's a wear issue myself, poor quality stock bearings. I love Scorpions other than the bearings don't get me wrong. I doubt it would be dirt but that's the 2nd thought I have.

I've got some Boca ceramic, greased (For life of bearing I was told by them), contact-less rubber fully sealed bearings can't get better than that so I'll see how that goes... The max RPM rating is much higher than what the motor spins at without load, even when greased.

When they feel notchy normally they have motor shaft play (all the ones I have had go bad did), that is never good and creates more noise and drains usable power.

Scorpion did change bearing suppliers a while back. They also started using larger od bearings in the HK series motors late last year

Motor bearings shouldn't really need any attention. When was the last time you oiled the bearings in your computer hard drive

I agree but hard drives are really not under the same load . And they are fluid supported bearings.

Quality bearings don't need replacing or oiling often.

They all say greased for life, but the life is shorter if its hot and the grease dries up!

Hey helicraze, I made it clear that I wanted a maintenance free motor and the longest possible lasting one for my exact Scorpion, I gave them all the specs and info and this was recommend for my needs.

Received an X-ERA 4020-1000 from CNCAddict to test. Will be comparing it to a Scorpion 4020-1100(although a 4025-1100 is probably more comparable). It is a BEAUTIFUL motor!
