Scorpion Motors

[Steven Vaccaro]

I've opened a dealer account with Scorpion Systems. So I'm looking for advise on what motors and kv's some of you guys are having success with?

Hk 3026-1900
hk 4035-800

Ditto, on the 3026 1900 and 4035 800. Also the 4025 series is another slightly overlooked size that is used in larger hulls.

[properchopper]

Take a look at the Scorpion Commander V-2 speed control ; comes with a very versatile programmer box and it'd be my choice to power the 3026 series. Among many options, it has adjustable timing, which I found the 3026 to be sensitive to.
[ Although Jan me both used an UL-1 speedy with good results]

The Scorpion battery meter is very nice for not many bucks.

Also think about stocking the Scorpion bearing lube - a good preventative maintenence item.

[tharmer]

The Scorpion 4035 - 800 is what we use in 1/7th boats. It is very reliable and has a really nice sound when turning about 21K. It is also very friendly to batteries with its relatively light current draw. An 80 amp Turnegy will be plenty for it.

I think the 3026/1900 is a decent motor for 14.8v and the 4035/800 and the 4035/630 are used in ginourmous hulls on 8-10 and 12s... I use the 800kv version in my 1/8 scale and boy is there power... I have heard that some guys are using the 630kv version with a great deal of success as well.

I would also suggest carrying some high quality sealed bearings to get better performance and lower maintenance. I have found the Boca stainless/ceramic Lightning series bearings a good choice in the Scorpion motors.

The HK3026-1900 motor is a wonderful 1/10 scale 4S motor. The -1400 may work well with 6S setups, but I haven't tried it. The HK4035-800 is well suited for big scale hulls on 8S or 10S, but you could also make the 4025-740 and -890 motors work too.

[calcagno45]

I haven't seen a maximum RPM on the 3026, anyone can enlighten me?

These motors are very interesting and seem to perform well in all applications. I'll be ordering one to try in my Revo.

[hydromaddicted]

Looks like it's fairly simple to get custom wound motors from them.
Great thread with advice and feedback for Scorpion here http://www.rcgroups.com/forums/showthread.php?t=660918
Make sure to bug them about the 16s 300amp:eek: ESC there working on.

[Ub Hauled]

16s 300amp ESC?
Are they in the automotive industry as well?! That's 17,760watts... who has a boat that needs that much power, or do you know anyone that has a boat that needs that kinda power?
I saw it a couple of years back in an RCX show in town and let me tell ya, it is a brick... at least it has the same size as one.

I agree with the bearings suggestion, a good affordable replacement would be nice to have.

And finaly, the Big Brother of this family is the 300 amp model. At full rated current, this ESC can handle 20,400 watts of power, or 27.3 HP! OMG The heat sink on the 300 amp ESC measures 4.63" x 3.00" x 1.75" (117 x 76 x 44 mm), and the overall length, including the capacitors, is 6.50" (165 mm). The overall weight of this ESC as shown below is 22.2 ounces (629 grams).

That thing looks almost as big as one out of an Electric Golf Cart - - FORE !!!

[rawsonreyes]

hey guys checkout the programming card for the esc's and they comes at no extra.watercool these and it's like magic.question:why dont any boat company make something like that so no more beeps.:thumbup1:

Steven

I've run hk4020 1390kv 6s in my triton with a top speed of 56.1mph :thumbup1:

They do!

I think 1900kv/rpm is the max, the cyclon have the 2000kv/rpm

[rawsonreyes]

hi i think this site is for positive info not rc boat politics please state which company has an prog card that is infared and it not sold separately, or like this system mr steven posted check out the site get the info then reply.it's easy to be a critic very easy.rreyes.:doh:

[Gerwin Brommer]

Did they improve the 300A esc's after some people tested them ?
http://www.mb-forum.at/video_xtreme_xhibit_crash_forum.wmv
Boat went "full=throttle" , the driver is a very very SKILLED man.
After this happened he immediately went back to his Schulze's.

[Ub Hauled]

Gerwin, I thought it was a radio glitch?! No?

[Gerwin Brommer]

Nope, no glitch.

[calcagno45]

I think 1900kv/rpm is the max, the cyclon have the 2000kv/rpm

I was asking about total RPM, no kv, like Voltage times KV = RPM.

[Steven Vaccaro]

Nope, no glitch.

For my own knowledge, how does a person find out if there is a radio glitch or an esc glitch?

[Ub Hauled]

Nope, no glitch.

Hmmm... dunno about that...
why didn't he turn the boat then? If it was me, I'd rather flip the boat then head
straight into the dirt... but that's just me.:tongue_smilie:

[Mel279]

Ops sorry for the mistakes, from what I've know for hk 4020 - 1390kv max rpm is 35,000rpm, dont remember where I get, maybe u can get it by googling

[Mel279]

I would also suggest carrying some high quality sealed bearings to get better performance and lower maintenance. I have found the Boca stainless/ceramic Lightning series bearings a good choice in the Scorpion motors.

So using the bearings that you've suggested, it require no lubrication at all?, as most scorpion stock bearing need lubrication if it were to be use frequently.

4020/1390....

max amps = 90
max watts = 1890

1890/90 = 21v (or 6s approximately)

22.2v* 1390 = 30,858

thanks for info Ub Hauled, appreciated:thumbup1:,

[tharmer]

Do these scorpion motors have a torque curve?

For my own knowledge, how does a person find out if there is a radio glitch or an esc glitch?

Steven he is a very expierencend builder and driver and had never before and after a glitch .

The boat is still running with the same Hardware with 40160Schulze

I'm not questioning his professionalism. But a question for my knowledge, how does a person rule out which area a problem is happening when it could be the esc or radio system.

[Fluid]

...how does a person rule out which area a problem is happening when it could be the esc or radio system.

Probably the only method available to most of us is what was described - if all else remains exactly the same but changing the ESC causes an issue, then it is probably the ESC rather than the radio. This isn't a 100% reliable test, we'd need to know more about the accident including did the racer try to turn, was BEC involved, were his receiver batteries charged, did the steering servo mount or linkage fail, etc. But with the boat destroyed it is no longer possible to reproduce the problem exactly, so we don't really know. Even the most experienced boaters can have the former issues which may not be related to ESC or radio failure.



hi i think this site is for positive info not rc boat politics...
There was no politics in the response to your question. In fact it answered your question exactly.

You asked: why dont any boat company make something like that so no more beeps.

He answered: They do

His answer is correct, lots of ESC companies make ESC programmers which eliminate the need to program with the transmitter counting motor beeps. You are upset over something which did not happen.
