I am planning on getting a Scorpion brushless for my Mini Titan, just wondering if I should go with a 2221-8 (3595k) or a 2221-6 (4400k) I currently have a stock brushless and I'm looking to upgrade. Along with the motor I am planning on getting a Scorpion ESC, either a 45a or 55a. So, opinions? I don't currently need the power, just planning for the future.

I can only comment on what I run with my bird.

I am a new scorpion fan boy too, thanks to Ktbone!! I have the 45amp commander esc, controlling the 430L alighn motor. My system never really ran as efficient as it does now wth Scorpion hardware backing it up.

Now, programming is a mother, let me tell you. They must have put all there effort and money into the fancy tin boxes they send the esc in for delivery, as the directions suck badly. So, alot of tuning will be needed, atleast for me it was alot.

From what my guys here tell me, the Scorpion 8 is the normal motor used for 3D, and regular sport flying. Bt the 6 motor is for all out stick banging excitment.

(I hope this post dose'nt offend anyone.......

I would get the 55amp. ESC
What is the advantage of the 55amp? Possibly use for later helis that are bigger, and need to the added amperage?

The stock esc will run a Scorpion 2221-6 with no issues. I've been using this config for over a year.

I like to play it safe, with the 55amps he won't have any problems going to a HK-2221-6. The HK-2221-6 can pull 52amps continuously.

The 2221-8 is fine too. The only difference is the gearing. If you calculate the KV, the -6 needs an 11 tooth pinion and the -8 is closer to the stock motor and can use the 13 tooth pinion for 3K headspeeds.

Both motors work quite well. I have two of the MT's with 2221-6's and one MT uses the old style stock esc while the other one uses a CC35. Both setups use an outboard BEC. One has digital servos while the other uses analog servos and honestly the machine with analog servos flies a little better. Go figure.

Only other thing that can go out on a brushless motor is the magnets. The Scorpion magnets are good up to 395 degrees F.

If I read it correctly, you can exchange the main shaft, and bearings when they wear, right?

This is awesome, a rebuildble brushless motor.

My question, when the hell is NOVAK going to get into the heli market, and build the best ORANGE esc, and motor for us. They own the car&truck RC market, or rather, they are legends.....

You can get every part of the Scorpion motor except the wire windings.

stay away from scorpion escs.

Down here in Singapore, every single person I've met running scorpion ESCs complained the ESCs get very hot.

Mine managed to eventually die due to the internal components shorting out after its heatshrink got chaffed by carbon frames and I junked it after that.

Just this weekend a buddy was was about to maiden his Rave equipped with the Scorpion 60A esc. After 2 minutes of hovering, the esc simply cut off and we out it was due to thermal shutdown. The ESC was BURNING hot while hovering @ 70% throttle
