Motor Advice

[terrabit]

I'm attempting to choose a motor for my L600 3d. Wow! Lots of choices! I'll be running FP 10s 3700's. I want solid perfomance both in terms of power and battery life. I like Neu motors. I've also been hearing great things about Kontronik's stuff and I'll likely be running a Jazz ESC.

So, what kv should I be targeting? What pinion? And how does all this play into the battery life/power formula?

I'm still relatively new to the Hellis. I'm certainly not a hard core 3d'er but, I am definately hooked!

By the way, I've got a Neu 1515 2d for sale if anyone is interested.

Thanks again!

You will need roughly 800KV. Not too sure of the pinion though. Check the head speed calculator...

The Tango 45-7 is the one you will need. Some folks run the 45-8 and it will do well. The Kontronic motor is great. It is a solid performer. The Neu "H" series also comes to mind Not sure which you would need though. Perhaps a 1910 or 1912. Make sure you get the "H" version as it has better cooling for heli needs. The other popular one would be the Z Power motors. I have no experience with these. Perhaps someone who does can chime in.

-1912-1y ``H`` version, big power, dubious longevity
-z50-800 decent power and effeciency, counter bearing is necessary due to soft shaft
-tango 45-08, effecient, not tremendously powerful
-actro 24-3, big power, effecient, and proven reliability

There are a few others like the 32-3, 1915 etc. that are overkill options too.

Since your still new to helis my recomendation would be a Tango 45-08. You will enjoy it's longer flight times and when you want to go to something more powerful in a year or so just upgrade. A 13 tooth pinion would work great on this motor for learning. :thumbup:

If you were more of a sport/3D pilot I would go with a NEU 19121Y/H or an Actro.

What stories have you heard about this motor? I've not heard a bad one yet. The closest I know of is Mercuriell's 1910 top coming off.

I had a couple 1912s have main shaft break away from the inner mag, also one had the shaft eat itself by spinning inside the od of bottom bearing. I have heard they are using a new adhesive to address this issue, I have not tried the new batches yet though. I had 3 1910s blow out the bearings in less than 50 flights as well :(, apparently though that was a bad batch of bearings as well.

Has anyone used the Tango 45-8? Mikado says they do not recomend this motor with 10s. They do recomend the Actro 24-4 but, I can't find one "in stock". (The Actro 24-3 seems to be more available) The Neu 1915H1Y is also hard to find "in stock". Any more advice?

Go with the Actro 24-3

You should also look at the Tango 45-7 (700KV) or Tango 45-6 (640KV) at Espritmodel.com. The motor RPM rating is limited to 25,000 for the Tango motors and if you run the 45-8 on 10S, you'll be around 27,000.

You could try my head speed calculator application (for Windows) and punch in these different motors to help see rated motor speed and head speed for a given pinion.

Hacker A50-14S 10-pole? Not super effieicnt, but cheap and reliable, with good torque. Buy 2 for the cost of a Neu or Tango. Good motor even for 3d. I run the A50-14S on my t-rex 600 (10s).

Thanks!

Can anyone tell me what head speed I should be targeting for mild to moderate with a premium on battery life?

Anyone know where I can pick up an Actro 24-3 or 24-4? They seem to be hard to get right now.
