Scorpion 3026 1400kv with stock 60 amp??
My LHS has the 3026 1400 kv in stock, Ive heard the 1400 is more powerful than the 1600kv but will the 60 amp cut the mustard?

I have a new 75 amp, but moneys tight and I wont be able to buy external BEC with my pay this week, also I cant solder very well and its more weight on the heli and also more hassle.

EDIT. pinion size would be appreciated also.

Thankyou.

I ran a 15 tooth with my Scorpion 1400. Power was awesome!!

My Stock ESC didn't last very long after switching to Scorpion motors.

Yeah I think the 1400 max amps is 80, and the 1600 70 amps.

What happened, did your esc smoke up? how long?

I imagine when the 60 amp goes up in smoke you also lose control of the servos too unlike when it happens on a 600 size heli with seperate power supply.

My ESC lasted about 20-30 flights with the Scorpion. One day it was flying fine for 2 flights and just quit working when going for a 3rd flight. No smoke or anything, it just wouldn't power up anymore. This was with the Scorpion 1600 before I got the 1400.

OK, I think I might take the risk with the stock esc unless anyone convinces me otherwise, at least for a couple of weeks until I can afford to by all the crap thats required to run an external bec with the 75 amp.

Sounds like I will have to use the 75 amp.

Would have been so much easier if I could use the stock, have to figure out how to make the servos work from it some how, I was also thinking of all the extra weight with the 75 amp, bec and all the higgley pigley wireing thats involved.

Dont know if Im reading the specs properly, but the scorpion 3026 1600 kv is about 1400 watts, compared to the Align 500l at about 800 watts. That seems a bit extreme that would mean the Scorpion is nearly twice as powerful as the Align, doesent seem quite right somehow.

something is wrong there lol. in a thread at HF there stating the 1400 is 1.5 stronger and a few guys have ran the 1400 for a long time with the stock esc governed on a 15t.

i like to take chances but i wouldnt do it on my 500, maybe the 1600 maybe not lol

Il have to have a look to see what the stock 60 esc`s max amp burst is, Im thinking of takeing the risk, sure would be a lot cheaper and easier than buying one of them UBEC`s.

Scorpion 3026 1600 is 70 amps max continuous current, the Align 60 amp is 60 amps continuous, 70 amp bursts.
The way I read that it should be OK, just.

I have an Align 75 amp I can use, I just cant be assed with all the wire soldering, and the bec will cost me $30.

EDIT. I only have $100 and the motor costs $107, an extra $30 for a UBEC is too much money for me, dont like the idea of not being able to fly for 2 weeks

I've been running the stock 60amp.
280 flights on the 1600 and the motor was worn out
30 flights now on the 1400 and everything is going great. 15T But I am only getting 3:20 second flight times at 100% and thrashing it hard.

Maybe this has helped but I mounted it below the battery tray with a big piece of zeal tape 300 flights ago. The lower vibration? or am I lucky?
IT's what I do.

3026 1400kv and Align 60 is what I've used in my last three Trex 500's with no problems whatsoever.
I run a 15T pinion on all.
I literally never use the word literally right.

This post is close to my heart, because I've been thinking of going the Scorpion route - but I am a little confused about the ESC capabilities etc.

I've read that the Align 500 motor is 650/850 max watts - which is about 40 ish amps, but I've seen posts on RR which suggest that the stock motor can draw peaks of 70A - which would put max power at about 1400W?

But I've read that the Scorpion 1600Kv is max amps of about 70A which also puts it around 1400W.

Does anybody have the true figures for both motors, so we can clear up the ESC rating needed.

No Ive had a couple of reply`s people who dunit Im inclined to give it a try with the stock 60.

The figures dont seem to make sense, like you say the 500l is about 800 watts, the 3026 1600kv is 1400 watts which would make it nearly double the power, the 1400 is more than double or more I think.

I could understand its more powerful, but twice as powerful, somethings not quite right there.

The Scorp is just that much more powerful but....

with a 425mm blade slinging machine,it's overkill.

You will see a cooler running heli.
You will keep a constant headspeed.
You WON'T see the hummingbird on crack stuff like the big dogs show off on youtube.
Some of that,crap,MOST of that is collective management far and away above my head.

Tic tocs are my most daring move and piro flying is still beyond me.

With the Scorp though,,,when I decide to punch out and go,it's gone as hell.

I use an Align 60amp esc with no gov and have tons-o-fun wittit.

3026 1400kv with Align 60amp is my favorite combo.

A Scorp 90 w/ switching bec might be a better row to hoe though
I literally never use the word literally right.

Hopefuly the 1400kv is back in stock on Thursday when I get paid, otherwise Il have to use the 1600kv, it wont be til the fortnight after that before I can afford to buy a bec for my 75.

I took apart my 500L and it looks to me like the shaft is worn where the top bearing touches it, Im not sure if its normal and a new bearing would fix it or not or if the actual shaft is worn.

Im also wondering if that play in the main rotor shaft is whats caused the motor to go so quikly, when I jiggle the main shaft by hand it doesent push the main gear against the pinion, but Im wondering if under high load flying situations it does(backflips, tic tocs e.t.c.), it wouldent have to do it very often to ruin the motor bearings.

Thing is I also had a look at a freinds ESP 500 with metal bearing blocks and after about 2 flights from new he also has exactly the same amaount of movement in the main shaft as I do with my plastic bearing blocks(also pretty much from new).

I think the play in the main shaft is fairly common, my ESP has it with new and old main shaft bearings.

Back on the motor front, there are posts on RR that say the Scorpion 1400 is a battery killer because of the power it can draw.

Also I too can't believe that the Scorpion's are double the power of the stock setup, but I could well be wrong?
