Anyone run one of the Scorpion 4020 motors in their 550, 1100 or 1390Kv?

Would I see a power increase or decrease compared to the 600M motor?

Nope.
600MX made a nice power boost for mine.

Now I went with a 600MX 510KV from the 600Pro, 112t main and 13T pinion (slant Mod 1 gears from 600Pro) and 12 power

Ive got the scorpion 3026-1210kv in my gaui 550. Its a great motor with plenty of power.

Heres a useful clip I "borrowed" from fellow HF member skigolfmike. Just ignore all the multi gear voodoo stuff as it only applies to the gaui.

I'm running the 3026-1400 in my 550. It's got gear ripping power. Let me tell you.

The -1000 is a 1300W motor and the -1210 is a 1380W motor. The -1400 is a whopping 1680W motor. That's a big jump in available power. I'm geared 16/61/20/61 and I'm running 2250 in hover with a Skytach on a 100-85-100 throttle curve near the end of a flight. Theoretical headspeed is 2500+ with this gearing.

I wish I had an EagleTree or something like it. No matter how I fly it I put 2200-2400mAh back in the 3200 Evo 30s after a 4:30 flight. At least I know when the timer starts beeping I have a little reserve. The bottom line is the -1400 may not be the amp sucking pig the H18 motor is, but, when you gear for high head speed, it's pretty close.

Based off the data above, I'd say go with the -1000 motor. More gearing options as you progress and it's only $75 while the Z20-980 is close to $100. Be wary of the Scorpion ESCs. I have one on a plank that works great, but I smoked an 90A on my Hurri 550.

Oh yeah, If you like scorpion motors but not the colors, check out the hyperion motor. They are done in blue/silver and are made by scorpion to the same specifications and use the same part numbers.

I am planning to change to a hyperion 3026-1210 just to get a nicer looking motor.

Thats exactly what I had in mind, smaller motor and batteries to keep the weight down but keep the flight time up. I thought about the 3026 1400kv motor because I know how much of a power house it is in a 500. The 4020 1390kv motor is 1890W though!

Viper VSH6013 is a drop in motor for the 550e. No frame cutting required like the 4025 series. It's also 1300kV which works better with the 550's gearing compared to an 1100kV motor. Very high quality as well.

Power wise I found it to be similar to the 600mx, which is considerably better than the 600m.

Yeah I got a chance to hold an 1800kv motor for a Trex 500 and was impressed with the quality. However the guy who was installing it is just learning so is only hovering around and even then the Viper got very hot! They are also more expensive than the Scorpions.

Heat is not an issue on the Viper 550 motor. I have no experience with the 500 motor though.

600mx vs 600m
This question may have been asked allready but I have not found a direct answer so here goes. My Flybared 550 is completly stock, I am considering upgrading to the 600mx from the 600m, will my stock esc/bec handle the extra power? Do you know the actual power consumption numbers for both? I am by no means a stick banger, sport to mild 3-d at this point, Thanks

Yes it will be fine. Power consumption is down to setup and flying style.
