but I really love the motors, my father owns 3 and i am about to get another one, and put on a Mini showtime.

Had 5 cells then went to 6 cells trying get more flight time, but it didn't help. Plane flew great but with 2300MAH thats all A123 offer right now, just short flights.

Thanks, missed that in the text of your post. Have you tried running A123s in both series and parallel, or are they just too heavy?

The 6 cell pack was autally two 3 cell packs that I hooked in Parallel to fly, thats the only way I could charge it, cause not having a charger i zip charged them.
they are heavy, as in to heavy to have two 5 cell packs. 3-5 cell themselves are not bad. over 5 cell getting a lil heavy.

I just completed another Scorpion power plane. This is the Slow Stick X Night Sticky Rip-off plane.

She is powered with a Scorpion 2215-22 motor, a Scorpion 25A esc, ar6100 rx, 4 HS-55 servos, 3s1320 TP lipo and a APC 10x7 SF prop.
Data is 14.8 A static, 145W, and she weighs a hefty 22.3oz, but carries 20 8,000 mcd LEDs

I will get some better pics tomorrow at the field during the maidening.

That looks really neat there. Did you home make the lights or buy them like that? Thats really cool, I have wanted to do something like that to my profile plane. Well I autally do have the wire of the lights inside the wings and got the lcd to the tip of each wing, but inside like that looks really good.

where did you get the stick mount for that motor? does the 22 series line up with the e flight 480?
I was thinking about that motor for my profile edge 540 it is right at 21ounce with 1100 a123's

I custom made the LEDs. It is not too hard. I have 2 other LED planes that look like UFOs. It is just tedious (sp?). I had to solder resistors on to each LED, then solder the leds onto very thin magnetic wire. It really is not hard, it just takes some time.

Liquidity,

That lighted wing is just awesome - Great job! That really makes me want to build something like that. I'd like to try it with a programable light controller so I could animate the lights a bit.

Hogger,

Those Yak-54's are sweet. Can I use your planes on my Scorpion powered models web page?

Tell me everything there is to know about the Scorpion HK2221-6...

Someone is sending me one for bench testing, and I know nothing about it. :o

My customer is looking for something which will produce a lot of SPEED, but very little thrust... Is this motor suited for this purpose?

Here is a start for you.

rcdude.com HK2221-6

From a little googling, it looks like more of a heli motor, than a plane motor.

Default HK-2221-6 Motor

The Scorpion HK-2221-6 motor is a high Kv outrunner made for helicopters and planes with small props. It's a drop-in replacement for helicopters like the T-Rex 450 and provides much more power than the Align stock motor. These motors comes in 6, 8, 10, and 12 turns. The 8 turn is the most popular T-Rex upgrade, while the 6 turn is for balistic power. The 10 and 12 turn are designed for those that want to run a 4-cell pack.

These motors are blowing away $150 motors in helicopter drag race competitions!

You will want to run the HK-2221-6 on a 3-cell lipo and use an ESC rated at 55A or better (pulls 52 amps max). If you're going to use this in an airplane application the best thing to do is download the Scorpion Calc software so you can play with some numbers and determine the best prop for your application. Here's a link to the download....

LOL -- yeah, I've played with the software, but I've learned not to trust software -- it's vastly different from TRUE bench testing.

My customer wants something that goes FAST... I guess he's going to get it.

52 amps!

Interesting motor. I am currently hitting 127-131 with dons inexpensive motors. I might want to give this one a shot, however 44000rpm is massive.

Scorpion calc is a different animal. I have 4 Scorpions and the 3 I have bench tested and flown with a logger have all matched SC very closely.

I agree. When bench tests are performed on the Scorpion motors the results are compared with the Scorpion Calc results and then the software is updated if needed. This keeps the software realistic.

Scorpion doesn't want inflated numbers as that would just result in unhappy customers when the motors didn't perform as stated.

Well, maybe it works well with Scorpion motors, but when I put in two "custom" motors (a Himax and a Mega), the numbers were pretty far off! :o

In short, I simply do not trust software which "predicts" power system results.

The Scorpion Calc software is "fine tuned" for Scorpion motors so I'm not surprised that a custom motor is not very accurrate. Fortunately, Scorpion motors are bench tested and props charts are produced that are very accurrate. These prop charts are conservative and realistic so you really do experience the performance shown. To me, this is the best feature of the Scorpion motors. I like to see the THRUST produced by the motor instead of just WATTS and Kv.

So you can "not trust" software and still easy determine the right motor for your model.

Slightly off topic but here is what I use on my EGE for lighting.

Powered off of the 8-cell NiMh directly and very light and bright.

Sorry Chris, I overlooked it. Yes, the Eflite mount works perfect with the Scorpion motor. Hodges did not have any Scorpion stick mounts in, so I checked if it woudl fit the EFlite perfectly, and it did.

Scorpion does have a stick mount that fits the 22mm series of motors. They are $1.95
