Hi all,

What are the current "good" motor choices for the L400 please? I'm looking for very good 3D performance with a minimum of 4 minutes safe duration on a 6S 2500 pack (i.e. I don't want a lunatic setup that's only good for 3-and-a-bit minutes). I'm currently running an Orbit 20-10 with a 21T pinion which works very well but makes the characteristic high pitched whine of that style of motor which I don't like.

Its not only the motor thats noisy but also the high rpm and gear type but yes the orbit does "screem" a bit then again so does the hacker a bit.

There are a few chioses like scorpion,hacker and mini pyro

I have run the Century 600+ 1050KV motor with a lot of luck. (6s, 2000ish HS, swinging 500s) I get a solid 4.5min on a 3850 pack. Its the biggest motor that will fit the frames I have found.

RIP ROMAN

Kontronik Tango fits too
I fly with Kontronik Tango 45-10 (1050 kv) and this motor fits perfectly in Logo400 frame. A lot of power, but needs hard bateries ... (setup with 500mm Blades, 6s 3300mAh)

Kyle has used for sometime now the Scorpion 3026-1400 on an 18 tooth @ 2750 head speed, and the performance is at the "high end" for 3D work.

You said "...very good 3D performance..." Of course that can mean many things to many pilots (-: Head speeds, flying styles and abilities GREATLY effect flight times.

Kyle's set-up with 2650 packs with his style of flying gets him 3:30 flights. Lower the head speed just a little (to say 2600) and put me behind the sticks, and you'll easily get another minute.

Or, leave it at 2750 and fly with less maximum collective pumping, and flights will be longer. But the reason for the high head speed is to get the maximum effect WHEN you collective pump. But even at 2600, many would say the Logo 400 gives "...very good 3D performance..." Which it does by the way It's all relative.

Anyway, the Scorp 3026-1400 is an option to look at. The flight times you get with any motor you chose is more effected by your set-up than your motor choice

Agreed with Dave, the 3026-1400 is powerful motor. It's also a little current hungry but not horribly so.

A bit more data from messing around with various motors on my Vbar Trex 500 (in the same weight class as the Logo 400 and shares the same motors, I've tested quite a few of them):

The 3026-1600 isn't quite as strong as the 3026-1400 but still has good power and is easier on batteries than the 1400. It's a good mix of efficiency vs. power.

The Neu 1706/1.5Y is between the Scorpion 1400 and 1600 in terms of power but is a little easier on batteries than the 1600-- it's an excellent blend of power and efficiency. It's low KV though (1250) so take that into account when picking pinions. It also has MUCH larger and longer lived bearings compared to the 3026 Scorpions which use very small bearings at the closed end of the motor can.

The Neu/KDE 1708H/N42 has absolutely silly amounts of power but is efficient at the same time; it's noticably stronger than the 1400 Scorpion but also more efficient so flight times are longer than the 1400 Scorpion (unless you're flying at full pitch all the time and using all the power the 1708H can dish out.)

If you want strong 3D and take cost into account it's hard to beat the price vs. performance of the Scorpion 3026-1400. If you don't mind spending twice the money and want CRAZY amounts of power the KDE/Neu 1708H/N42 is an awesome motor and beats the Scorpion in all areas except price. If you want a great blend of flying time with good (but not crazy) power then the Neu 1706 is an excellent choice or for about 1/2 the price the 3026-1600 is in the same catergory of good performance with good efficiency. My Trex 500 currently flies with a Neu 1706/1.5y and I'm happy with it given my current flying style (big air aerobatics, high speed FF & circuits, some funnels, tictocs, rainbows, death spirals, etc.)

Another motor which is probably excellent but I haven't tried is the Kontronik MiniPyro.

Dave and Kiba,

Many thanks for your helpful comments. I have 20, 21 and 22t pinions in stock and was wondering about using a Scorpion 3026-1210 motor rather than the higher kV options you mention just to avoid buying more pinions! Apart from the kV and hence a different ratio, the motor dimensions and heat/power capacity should be basically the same or am I missing something?
