Scorpion SII-3026-710?
« on: December 10, 2013, 06:39:40 AM »
I've done some digging with a small shovel, not a big one yet.

I came up with the Scorpion SII-3026-710.

Looks like this motor will work well with 550 sq's. 55" in span, eliptical wing design.

Certainly it would be nice to know if others have had experience with this motor?

Or, and more importantly, is there a better choice? And why?

Not sure if the Scorpion SII-3026-710, can be changed to front mounting? The motor HAS to be front mounted.

I'll copy Robert's placement of his battery, at the LE standing up. Different size choices in sizes? I have limited height and space?

I may design the wing where I knotch out the LE to park the battery closer to the CG. I can do that.

All input will be appreciated.

Charles

Charles,, at the risk of being a broken record,, at the top of this section there is a pinned subject called "list your setup"" It has LOTS of information about setups,, I have no doubt that the Scorpion is listed there, I think Christ Rigotti used one for awhile in fact,, and several others,, you should be able to find out all you need there by doing some reading not to mention gathering a bunch of peripheral information which would be advantageous,,

Mark,

Yes, you most certainly are a broken record.  LL~ LL~ LL~

Glad you have a since of humor.  ;D

Yes, I've been all through there, even took notes.

As you can imagine, there's such a mixture. Could be confusing to a layperson.

Besides, it's 2013, almost 2014, there may have been improvements or even new motors on the market?

Only the electric guys would know that.

I can't afford to make any mistakes that's why I'm looking for guidance.  n~

What are you comfortable with or using?

I suggest you contact Will DeMauro ... He is the best source for electric from the NYCLST ... He uses Scorpion motors.

Joe,

You're using a Scorpion motor. Do you like your set-up? What's the sq's on that model and the weight? Front or rear mount?

I wanted to spin a larger prop, that's why I had interest in the 3026?

Best flying set up I have.  Will DeMauro suggested it.  I had to turn the motor down to 10000 RPM-s to get 5.4 lap times on 60' lines.  The vertical is extraordinary.  This is the right setup for a 550 sq in x 54 oz model.  I have it rear mounted.  I haven't used the 3026 Scorpion motor.

Save me a bunch of typing. 4 or 5 cell setup? Airframe weight? You say larger prop? How much larger, like exactly what prop and why? All motors are reversible. I'll work from there. 3026=most likely too big !!!

Yeah, what Crist said !  You definitely will NOT be dissapointed. In fact you'll probably be happy as a clam, or thrilled to death even.  ;D

Crist,

Took a good look at your work. Nice!! Kudos!!  H^^

I don't believe I've been in that build thread for your Thundervolt. It was awhile back and I had no real interest in electrics, my excuse for not seeing your Build.  ;D

I did make up for it.

Plenty of info to digest, plus the building process, start to finish, is well documented with fine photos and great text.

Nice to see a fellow modeler doing Build Threads like this. Kudos on that also.  H^^


And thanks for that link!

William,

I just noticed your reply, thanks for that. Sorry I missed it or I would have responded earlier.

I would like to keep the cell setup at 4S. Only because I believe this would be lighter?

I have added sq's. I'm now at 609 sq's with a span of 60". The wing is elliptical. 13x4 prop. Better blanket of air with less effort?

As far as weight, I'm inquiring about that in another Thread.

I'm thinking AXI or Scorpion?

Ok, AXI or Scorpion, Don't matter, pick one use it. No mistake possible. You wont know the difference. Why not the Cobra? Save some money and you still wont know the difference. If you want 4 cell use this one Cobra C-2826/10 Brushless Motor, Kv=930 and a 4s 3000-3300mah battery. If you decide on 5 then copy Crist. I can tell you his setup works great. I had the pleasure to fly his plane a few months ago and he had plenty of power to spare. While I'm here save yourself a lot of time and effort. You don't need that rear bearing support!!!!! I know someone with almost 400 flights on the same motor and bearings without using a support. I WILL NOT use one on my new plane. My plane WILL have the above Cobra in it. Since this will be my Nats plane, it will probably be flown harder than you will ever fly and I have total trust in this system.

Will's system works ... I followed everything he told me when I decided to go to electric ... the best part is that I made no mistakes with equipment. I only had to buy once.

William,

Thanks for the quick reply, I appreciate it.

What do you expect your Nats airplane to weigh? What will it be?

I used SII-3026-710 one season, I needed 2 motors, while I fly one AXI 2 seasons. The problem with SII are too small bearings, they cannot stand what I fly, otherwise ok, may be even better - for example magnets are better (for higher temperature), everything else OK for us, it means all depends how much you fly, if you count with very often flying, choose axi, if you fly only seldom, SII will be OK

they have even very similas dimmensions and also bolt pattern, so they are exchangeabe but AXI is little lighter (means does not weight so much as SII but also does not stand the same power)
