Astro,
Where you able to get any watt readings for the Align motor. I just recently got one with a 35 amp ESC. I did a bench test using it with a "Watts Up" meter and came up 427 watts at 42.9 amps. Does this correlate to what you are getting. What are your flight times?

astro1111

I'll try to do it today but that seems very high. Did you buy the 3550 KV or the 3800 KV motor?

AETCBoom4

Its is the 3550 KV motor and is listed as an outrunner, but its has the shape of an inrunner. The ESC has a bunch of features such as adjustable motor timing and throttle response. The ESC is an Align 35 amp.
The numbers I came up with are static bench test numbers with the stock PZ GB 3-1 ration and stock PZ 10x8 prop. The motor is definitely powerful and has proportional throttle response, but at 400+ amps and 42 watts is way to high. This motor might work well as a outrunner for an Ultrafly product.

Astro, let me know what you come up with.

alabama,

good to read you got things sorted out and that you're flying and enjoying the model...that last prop nut should be on there pretty right...i recommend getting a self locking nut...they have a nylon insert which prevents it from backing out...you can also use locktite (threadlock) but it's more expensive then a self locking...you also have to apply it everytime you remove and replace the nut and you have to wait for it to cure...hope this helps...

gunracer

aetc,

that align 3550 kv motor is rated for 28a...if your static numbers are correct, then the motor is being overloaded...depending on what batt you're using, you also run the risk of overdischarging it...if you want to use the motor and get the amps down, then you should look at a 4:1 or 5:1 gear ratio and/or decreasing the prop size...

Yeah, I copy that. I might save this motor for something else. Possibly use it as a outrunner for the UF P-40, like we discussed earlier. Of course this is after I replace my PZ-Spit and of course Mustang 6 series after yesterday's radio hit. As I was sorting through the wreckage of the Stang I found the elevator locked at full down, while my tx had full up trim. I know when I took the radio hit I gave her full up stick so I am preatty sure the radio hit caused the crash. Sucks to say that I have all motors and no planes now.[:'(]

Hey, guys,
Please don't take this wrong but I believe the Align 3550kv can't pull 42 Watts but if that's what your seeing..... I have an Apollo 25 Amp ESC, Align 3550kv , stock Parkzone Gearbox, an a DN 15C 2150maH battery. I have flown the Spitfire 17 times for 168 minutes total (nearly 3 hours). My max flight was 17 minutes. My average time in ~12. The reason my avg over 17 flight is ~10 is because I had 3 5 minute flights to run my batteries down and one crash. I will shortly try to find my wattmeter but my motor and battery are just warm at the end of flight and I live in Florida. I hardly ever flight above 80% but have flown at 100% vertically at times. I will try to get you a reading in the next few hours.

Astro,

Believe me, I like the throttle proportion and the power this motor puts out is crazy. Do you have specifics of the motor you are using? Is it the Align BL430L 3550KV?

astro1111

Okay, i did a quick test with a battery that was not fully charged and with the Astro Flight Super watt meter and here is what I got:

Upon connection:

Volts: 12.27
Amps: .15
Watts 1

At full throttle:
Volts: 9.45
Amps: 32.05
Watts 304

I'm cooking another battery now and hope to have more info in about an hour.

astro1111

Yes it is a BL 430XL 3550kv

astro1111

Okay, Here is my test with full battery that was not fully charged and with the Astro Flight Super watt meter:

Upon connection:

Volts: 12.4
Amps: .15
Watts 1

At 25% Throttle:
Volts: 12.0
Amps: 3.1
Watts 36.23

At 50% throttle:
Volts: 11.15
Amps: 10.05
Watts 113

At full throttle:
Volts: 9.26
Amps: 32.06
Watts 304

That seems strange, mine are way out there. To confirm is this the exact motor you have.

AETCBoom4

Just curious. What batt are you using?

astro1111

That is the one!
I'm using an Apex Mk3 15C 2100mah battery. Maybe that is why I'm seeing only 32-34 Amps and 300 Watts. Using a 35 Amp ESC is over kill but like my friends FW-190, he just linits his throttle. If Align had a 3200KV motor with the same pyshical size it would be perfect. This is the only 3.17 mm shaft motor that is 27.5 mm wide and beveled to fit into the gearbox. It is perfect and it has a ton of power.

AETCBoom4

Astro,
Better yet here is a page from Align website. I wonder if we are looking at 2 different motors.

AETCBoom4

Astro,

I think I may have found the answer. I took a watt meter reading with an old TPS 11.1, 2100 (not fully charged).

Align 430L-3550KV
TPS 2100mah, 11.1, 10-12C sustain, 16C burst
Base batt voltage:11.74v

WOT
8.63 volts
289.2 watts
33.32 amps

So I guess this motor will work with a lower C rated battery, but if used with a TPS prolite 15C/24C burst, you are looking at 400+watts and 42 amps discharge.

Hint to self: use a lower C batt with this setup.

alabama

Anuone have any videos of them and here spitty??? I would like to know of any tricks you can do because i am doing some but there simple and kinda pathetic and i would like to expan my horizons...

I am creating a video it will be done by tuesday if anyone would like to see it. My friend chases and catches the plane on fly-bys and we fly it low and upside down and stupid things like that ... I love this plane!!!!!!!!!!!

gunracer

what about this align motor?...kv is 3150, shaft is 3.17mm and it should fit......

http://www.align.com.tw/shop/product...roducts_id=962

although the motors are designed for heli use, i see no reason why you can't use them in planes as long as your setup does not exceed the specs of your components...

gunracer

if you want to use that setup, you want to get a batt (20c 3s 2100mah) that can safely supply the current the setup wants to draw...in this case 35+ amps...using a lower c rated batt to get the amps down is not the answer...in your example above, you are *****g out and killing that tps 3s 2100 rated at 10/12/16c....at most it can burst discharge 33.6a and maybe continously discharge 25.2a...

if you want to use a lower c rated batt, then you need to go up in mah to make sure the batt can supply the current the setup will draw...a 10c 4000 mah batt can supply 40a just like an 8c 5000 mah batt can...the problem with the higher mah batts will be their weight...hence the reason for a 20c 3s 2100 batt which can supply 42a continously and probably 60a burst but weigh half as much as a 10c 3s 4000 mah batt....hope this helps...

heartofmadnes

The Spits can be mod to use retracks, I set them up on mine. The electronics have a jumper labled gear on the reciever. So when your servors plug into that and you go from low rate to hi rate the wheels will retract. Now I already set the spits with a 3200kv brushless and 3s 2100 lipo so I dont know how the retracts effect the weight of the plane stock.

traxxboy

please show us some pics of your retract setup. I would love to hand launch mine then lower the gear for a landing.

Trev63

Yes, please post some pics of your retract setup. I have yet to see a single picture of this done.
Where you got the retracts from would be worth mentioning as well.

thanks

My spit is on its way..ups needs to hurry up!.. I am looking at those tower pro combos at unitedhobbies... will any of them be worth a damn for the spit? These BL numbers havnt sunk in yet. I have 4 channel lab scopes and fluke meters and can fix a broke down computer controlled gas engines but after work trying to consume all this info on a worn out brain seems challenging. I dont need alot of speed a little more than stock would be nice but mostly I would like more flight time and some more pulling power. What do ya think?

AETCBoom4

Is your Spit the ARF or RTF version? If it is an RTF version all you need to do is swap out the motor for a BL inrunner. After looking at United's website, the tower pro combos are outrunners. If you plan on going to an outrunner, you'll have to construct custom motor mount.

You could just go inrunner and use the stock GB. If this is the case, you will need a 28mm can sized BL motor (3000 KV or lower), a 25-40 amp ESC (based on the KV of your motor) and a 32P 12 T pinion 3.2 mm pinion gear. Of course, a good 3s 2100 mah lipo battery and charger.

Hey, there. I looked at this motor and its 28.2 mm wide. How does it fit in the standard gear box? It is also almost 50 grams heavier than the Align 430L. I love the price but is this a Bit@# to put in.
