Default Motor Recommendation

Have purchased a crashed 5.5 which is now sitting on the work table and is in need of some TLC to get it back in the air. It appears from the Castle demo mode that an 1100KV to 1220KV is the motor for the 5.5 with available pinion choices. I have a spare Scorpion 4020-1390 with 6mm shaft but head speed looks to be a little crazy compared to my Outrages.

Anyone ever try a motor similar to the 1390 or is that just too far out there?

I think the 1390kv will be a little too much it may be okay for a 4S or 5S battery. I also think that it requires a longer pinion shaft the pinion is 26mm and I donít think the 4020ís are that long.

Hey Larry,
Thanks for the reply. Shaft length shouldn't be an issue since it has a 4025 shaft installed. As you mention, I am afraid the KV may be too high for my 6S packs. Wondering if anyone has used a similar KV motor and what there experience was.

You should double check the length they make three different 4025 length shafts. I did measure my pinion to get length I stated. You could try your motor and see how it does before spending the money on a new one.

Hey Larry,
I have come to the conclusion that using the 1390 would not be a smart move due to potential head speed and having the ESC so off on optimum switching of the FETS. Something bad is going to happen. Going to purchase a motor with proper KV for the 5.5.
The Quantum 4125-1100 Goblin 570 motor looks pretty good.

I think the Goblin shaft is shorter than the one that you need for the 5.5 atleast on the Scorpion. I was looking at a used Scorpion 4025-1100 Goblin Edition and that's when I figured out they had three different length shafts on the Scorpions the Quantum 4125-1100 Goblin 570 may be different I haven't looked at them but there were a few for sale on the forum a few days ago. I just looked it up on Anythingheli.com and I think it will be long enough.

I did a little more looking last night and KDE is the same as Scorpion they have three different length shafts for the same motor and the Goblins are the shortest and the KDS the longest. I didn't find a Web site for the Quantum motors.

The Quantum 4125-1100 motor I currently have my eye on matches up dimensionally to the KDE 600XF with the XL shaft so it should be perfect. Looks like the 6mm part of the shaft is ~37mm from the information on the box.

Sounds perfect let me know how you like it. I have the stock KDS 1100kv and I may need to up the gain on my Ikon governor or maybe up the HS (running 2200rpm) but sometimes it feels a little under powered.

Motor came today, brand new Quantum 4125-1100 that has never had bullets soldered to it for a great price. Couldn't be happier with it.
Pinion was off just slightly on the flat, needed to sit just a little higher on the shaft. Motor spacer from a Rave Ballistic took care of that, now fits perfectly. Currently have a 20T pinion installed, Castle governor says I can run a little over 2300 rpms which is very similar to my Outrages. Time to order the replacement parts now and get her in the air again.
