What about Scorpion HK2221-6 on minititan?

[uragano47812]

Hello i see this motor at readyheli. I want to know if Scorpion HK2221-6 that is a 480 class motor will work well on MT or if it will be too much powered.

The MT has a larger head than a 450 class heli so i think that it can work.

Will scorpion 55A ESC plus Scorpion HK2221-6 be handled by my 2170 Evo25 lipos?

Let me know what you think

Thanks

[uragano47812]

No one? What do you think?

Hi there! I have an incoming order on a Scorpion 2221-8. I made the choice based on my scanning the net for info. I havn't seen the model you asking about. I will return with report when I mount the engine i my titan.

Thanks for the interest in the Scorpion Motors. If you are interested in checking out the performance of the HK-2221-6 motor, take a look at the following link for a video of Nick Maxwell Flying a Gazaur Poseidon with the HK-2221-6 motor with one of the Scorpion 55 amp speed controllers.

Nick reports absolutely awesome performance, but it is very hard on the mechanics of the heli running this much power through it. He has to replace the main gear every 12-15 flights, and wears the head out pretty quickly to.

I know that the Thunder Tiger Mini-Titan is a good machine, but it is not as tough as the Poseidon, so the HK-2221-6 motor would tear it up pretty quickly.

One of the local hobby shop owners has a Mini-Titan with the HK-2221-8 motor and loves the performance. Actually, the Mini-Titan will fly fine on the HK-2216-12 motor just fine, as long as you do not expect the most extreme 3D performance.

Personally, I would recommend the -8 motor for the Mini-Titan, as the -6 would just tear things up.

Thanks!

Thanx for the info. Is there any big advantage in the -8 over the -12 if I'm not doing 3D? What esc do you recomend for each. I need a new motor and esc for my MT and since my LHS carries Scorpion I thought I would give them a try, since I've heard nothing but good about both. Thanx.

dynodude,

You must be referring to Discount Hobby Center on Claremont Mesa. There is a great group of guys working there! If you go there, ask for Stephen, he is running a 2221-8 motor in his Trex 450 and loves it. I think that he only works on Monday and Friday right now though.

To answer your question, You need a certain headspeed for the helicopter to operate properly, and for most 450 size machines, including the Mini Titan, this is in the 2900-3200 RPM range. If you run a 2221-8 motor with a 12 tooth pinon in a Trex 450, you will get a head speed of around 3050 RPM. I am not sure about the gearing in a Mini Titan, but I am sure that it is pretty close.

If you run a -12 motor, it has a Kv of only 2580, compared to 3595 for the -8 version, so to get the proper headspeed, you would need to run a 16 or 17 tooth pinion gear.

If you want a little less power, then you could drop down to the next size smaller motor in the HK line, which would be the HK-2216-12 motor. This one has a Kv of 3350, and can handle up to 35 amps of current on 3 cells. This is actually about 25% more power than the stock motor that comes with a Mini Titan, so it is still an upgrade, just not as much as the HK2221-8 motor would be. With the HK-2216-12 motor, a 12 tooth pinion will give you a headspeed of of around 2850 RPM, and a 13 tooth pinion will give you a headspeed of around 3080 RPM.

Discount Hobbies does not have any of the HK-2216 series motors in stock right now, but they do have several HK-2221-8 models available. If you want to get one from them, just let them know and I can send one down with their next order.

For an ESC, we recommend the 45 amp model for a couple reasons. First, it can handle the power spikes generated when performing extreme 3D maneuvers later on when you get to that point, and Second, the 45 amp ESC's have an extra regulator in the BEC circuit than the 34 amp models do, and that gives you more current available to drive your servos and Gyro.

Thanks!

Thats to funny. I spoke to Stephan just today and he also recomended the -8 motor and 45 amp esc. He raves about the power the -8 has, and in fact, I have a really cool video of him drag racing his heli at the Border Fun Fly, and he smoked the other guy by half the field. I'm actually a little concerned that it may be a little to much power for the type of flying I'm doing right now. (hovering,piros,nose in, 180's and fig 8's) I'm currently using a 430L/3550 and Xcalibur2200/25c on a 12t pinion and am very happy with the power and smoothness of this set-up. I currently get about 6 1/2 mins. flight time on a straight 85 TC. If there is any increase in flight time from using the 2216-12 then I might wait.But if everything else is equal, then I'll go head and get the -8 so the power will be there as I get better. Thanx for the reply and the great info! BTW, you're right; They are a great bunch of guys over @ Discount Hobbies. Real helpful and a great selection of "stuff".

dynodude,

Can you get me a copy of that video. I would love to put it on my website, and have it on display at the Chicago show next week.

Contact me with any details!

I will try to get you a copy of that vid. I tried to send it to Stephan but my e-mail would'nt let me send files that big. Really, it's only about 25 seconds long, so if nothing else, I will put it on a flash drive and either give it to Stephan or mail it to you.
Picked up a 45 esc today and put it on my MT. What a breeze it was to program. No more throttle stick gymnastics and instructions that don't require an interpitation of Asian to English language.Did'nt notice any increase in power from the motor, but it was much more consistent. What I did notice was an increase in tail response. It just seemed to react quicker and was more precise. Also, my batts did'nt run down as much. I think I can add about 30 secs. more flight time and still be at 11.15v. Still up in the air about the motor choice. If I run the -8 at 85% will it be less efficient than the 2216-12 at 95-100 on a 12 tooth pinion? What do you think? Thanx.

Check out http://www.innov8tivedesigns.com/index.php for Scorpion Motors, ESC's and specs plus recommends. Saw it on the motor forum at RCGroups.

Would the Scorpion 2221-8 give me no bog in doing tick-tocks on the Mini-Titan? Which one is the best to produce no bog on 3s?

BTW, the Mini-Titan has the same 150t gear size as the Trex 450se, but is alot heavier.

[Funky]

I think only collective management can give you no bogging during tic-tocs. I am running a very powerfull setup now, but I can still make it bog pretty bad during tic-tocs if I lose my timing.

[uragano47812]

How are Scorpion ESC? anyone has try 45A or 55A?

This is because i have to change my quark33Av2 and i have to decide if to buy CC45 or try one of those new ESCs.

[brovic777]

If my Align 35amp ESC can't handle this new HK2221-6 525watt monster motor, Im gonna try the Scorpion 55amp ESC next.

[uragano47812]

Hey Vic any news about your new motor?

Here is a video of this powerfull motor.

http://www.youtube.com/watch?v=fDhVT8biz3E

I dubt that you Align ESC can handle it... 52A max amps for this beast.

Got it installed, but still gotta go out to a field and test it out. Hopefully this Saturday I'll take it for a crazy spin and see how much power I get on a 10t pinion!!!!

[flyanything]

Got my 2221-8 today... am I missing something or is there a problem with this motor fitting the MT motor mount plate? The stock TT motor fit fine but I can't get the screw holes to line up no matter which way I rotate the motor.

John

[Bayward]

That sounds great ! :thumbdown: My 2221-8 came yesterday and I have not had time to even look at it yet. Hopefully mine will fit.

I just measured the mounting holes on my motor. They appear to be 17mm X 20mm. Not the 16mm X 19mm I expected. I just went to the Innov8tive site and cannot find the mounting specs listed. Do you know where they might be listed ?

Bummer, I really had no thoughts of spending an afternoon cutting and filing a motor mount to shape. :mad:

Bob

[flyanything]

I used a dremel tool to make the mount plate holes a lilttle oblong so I could mount this motor. Luckily the MT has a very flexible gear mesh adjustment with the way this mount plate pivots... a very cool design feature.

John

[Bayward]

I agree, the pivoting motor mounting plate is a super great design. Makes it real easy to obtain the proper gear mesh.

Bob

[Bayward]

My measurements on the bolt hole spacing for the HK2221-8 were wrong. The hole spacing is 16mm X 19mm.

I picked up a Scorpion -8 V2 from my LHS, Gyro Hobbies, in Orange County a few weeks ago now.

I put it in my Kasama-headed Mini Titan, replacing the stock outrunner, but leaving everything else the way it was, with the stock ESC.

This motor provides SICK power. I can't even imagine putting the -6 in this thing.

Go with the -8, with the 13 tooth pinion, have good packs, and run them 5 minutes in 100-95-100 or 100-100-100 curve.

The MT is a BEAST with this motor, and it comes down cool. I have no problems with the stock Ace ESC.

Good stuff. I did a fair bit of research before picking the Scorpion. The quality is top notch too.

Get the -8. You will love it.

HOWEVER!!!! I had to file down a motor plate to get it to fit. It did not fit my stock motor plate mounting positions.

Took 10 minutes with a little 4 dollar rat tail file.

-Aox

[Aox]

FYI, Scorpion, or something fried my Stock ESC.

Changed timing on the ESC to AUTO, and turned on gov mode.

Ran it once to tach the headspeed, got my speed, powered down.

ESC never worked again.

Not cool, but oh well. Time for a CC45.

[Bayward]

It is only money, right ? What is another C note ? :arggg:

Just pulling your chain a little. Sorry about the ESC.
