I thought it would be a good idea to start a thread to discuss the new Align 430L-3550 motor and the best setup.


I had a chance to make one good flight this morning before the winds came up. I just got my 430L yesterday and installed it with an 11t pinion. I have a 450XL, Mavrikk blades, CC Phoenix 35, TP2100 3s ProLite.

My old setup was a Mega 16-15-3 with a 13t pinion. This first flight was a little disappointing. The straight-line speed was better than with the Mega but it bogged down a lot more during 3D. The 430L is a lot smoother and cooler running than the Mega – I have not flown enough to tell if the flight times will be longer. Since everything was very cool after the flight I definitely need to load down the motor a lot more with a larger pinion.

Ben, let us know how you make out with the 13t.

I too am curious to see the results.

I finally got to fly my 430L with a 13t pinion and it was a little better. After some experimenting I found that it would hold 2500 in a 10 degree pitch climb and bogged down slightly during 3D. This motor is smoother and has a slightly higher headspeed than my old Mega 16-15-3 but the Mega definitely has more torque and bogs down less. On the plus side for the Align 430L it does run a lot cooler that the Mega.

As far as flying goes if you already have a Mega 16-15-3 I see no big advantage in getting a 430L.

I now have a Neu 1107/2y on order (actually its backordered, I ordered the one with the optional 3.2mm shaft so I can use larger pinions). Hopefully it will be better on a 3s LiPo. Calculations indicate that it should be a killer with a 12t or 13t pinion. I would really like to find a 3s LiPo setup that will hold about 2600 during hard 3D.

If the Neu doesn't work out for you, I suggest the Lehner 1020/17,

After recharging the batteries I fond that for a typical flight of FFF, aerobatics, and some 3D, that the current draw of the 430L was higher than with a Mega 16-15-3. This was a surprise as I had read that the Align motors were fairly efficient. The one flight I did Saturday with an 11t pinion also had a fairly high current draw. So for a flight where you are constantly loading down the motor the Mega appears to be more efficient.


It seams to me that the Kv rating of 3550 is a bit inflated. With the same pinion it does give about 1000 more headspeed that the Mega 16-15-3 (Kv=3000). If you assume 1000 more head speed that would be 2500/2400 * 3000 = 3125. So under actual flight conditions the KV rating is way high. Perhaps under no load conditions 3550 is the number but that’s not much help in the real world.

BTW I do know that the real formula for RPM under load is:
RPM = Kv * (V – (Rm * I))
The problem is getting accurate motor constants from some manufacturers.

Dennis,
I would really like to give a Lehner 1020/17 a try – do you have any accurate motor constants (Io, Rm, Kv) for this motor so I can compare it to the Neu Motors.

Dennis,
Refer him to the DPR graphs you posted.

BTS,
Most of the guys flying serious 3D with a TRex in this area are on 3S with the Lehner 1020 17. On a 10 tooth pinion it will give you a solid 9 minutes of 3D on a TP2100 Prolite. I watched Charles Rosario, a sponsored pilot, fly his CDE with the Lehner going through his routine yesterday afternoon. No bogging, no problems! I am sure there are other motors that are its equal but I have not found one yet. I am just an "old duffer" compared to those guys but I fly with the Lehner as well in my CDE. I have the 430L in my HDE. It is a nice motor but "it ain't no Lehner" when it come to power!

430L – the more I fly it the more I like it!

I finally got some good flying weather (very cold but calm and sunny). After doing a bit of setup work I find that I like the 430L with 13t pinion a whole lot better. I was running a little too much pitch so it cut it down a little to +/-10. I also had some belt problems (wearing on the side) so I installed a metal tail gearbox and new belt. I also installed a CF tail boom that does not expand and contract like the aluminum boom. This was a problem in the winter as the belt tension was always either too tight or too loose.

Now I have a very nice flying helicopter. With the 13t pinion the cyclic rates are really incredible. After flying my Raptors this thing has an incredible roll rate. This combination is definitely a keeper. I will put the Neu 1107/2y on my second T-Rex so I can do some comparison flying.

More test results:

I found that the 430L works very well with a CC Phoenix 35 in the governor mode or with a throttle curve with the latest software. With my setup setting the governor somewhere in the 2500-2600 range is something that I can hold during 3D. This is flying during cold weather (25-40F) and LiPo cells do better when warm so this may be higher in hot weather. I am very happy with the performance (fast FFF and excellent climb) and don’t really need anymore headspeed – which would just reduce the flight time.

For a typical flight of hover, loops, rolls and 3D I have an average current draw in the 13 to 14 amp range. This is below 7c so the cells are not working that hard most of the time.

I, too, love my 430L. The trick like you said is not to overpitch the heli. For the price it certainly is the best deal on the market.

I also have a 1107/2Y running 11T pinion. I've only had two flights with it but so far it's probably the best motor I've ran (on 3S). Power is similar to the 430L, but efficiency is better, resulting in longer flight time. I would love to go to higher pinion but haven't found one yet. Wish I got the 3.2mm shaft like you ordered.

I would love to try a Lenher one day, but at those prices, I rather buy 4 more 430L!

Got a 450TH coming for comparison. Stay tuned.

Gary: My Santa must be a different person because when I asked for a Lehner, I get yelled at.

I have not flown the 450th but I can say that I like the 430L enough to use it on all three of my Trex helis. I was a little surprised when I first read BTS's comments as I wasn't seeing the bogging with a similar set up.
We run
Hyperion Blades
430L-13 tooth
Quark Controller
TP2100 3s ProLite.

We get good 3D performance and a head speed of about 3000 for around 8 minutes.
I'm glad to see that BTS is coming around to liking this motor as it is doing very well for us.

Hey Step280,

I agree...I like the Neu 1107-2Y just a bit more than my new BLUE 430L. BUT the 430L is working nicely.

I have the smaller shaft 3.2mm 2Y so a 13pinion is not a choice. I may look into the larger shaft 2Y. I think the 13 on that motor would really "pull" hard in flight.

Anyway, the 430L is working very good I must say in it's defense. It runs very cool. And so far I can never decide which Rex to fly...the 2Y motored one or the 430L one.

I also have the Quark ESC controlling the 430L too. Still working through the setup for my flying style. The 2Y is controlled by a P35. Both are working great.

__________
Best Regards,

Ron Osinski

steph280,
All I got when another Lehner was mentioned was a look and a sigh! Heidi is kind of used to me and my Hobbies. She has been putting up with me for 45 years nows. Anniversary was yesterday so much of the day was devoted to being attentive and on good behaviour I did sneak out to the parking lot for 2 flights just before dark though. I am working on my Quark programming with the 430L.

Hey Johnny, thanks and yes it is. I like the new tail rotor set up on it. The pitch plate is hinged and gives you full use of the pitch range.

Gary, whats to work on with the Quark programming? That controller works best right out of the box!

rstacy,
I am working with the Quark governor modes. Every other speed control I have introduces some tail wag in governor mode. This one looks promising

I am really liking this 430L! Out of the other motors I have tried (400dh and Medusa 3400) the 430L has been the best. I was surprised how well it even worked with a TP2100gen2 pack. The 400dh and Medusa just didn't have the power with the gen2 pack. Of course the 430L with the 2000prolite is where it's at! The light weight of the pack along with the power it can deliver make it a great combo.
I was eventually planning on going to a 4s setup but if I can get this kind of power out of a 3s setup I might just stay with 3s. With the newer gen of lipos getting better and being able to deliver more I don't think the need for 4s is quite as high.
