I have a logo 500 3-d heli, and must say that it is the best smoothest flying helicopter that I have ever flown or owned. This I say after flying the heli for about 5 minutes before both motor and esc went into thermal meltdown. So here is what I HAD

LOGO 500 3D
MOTOR Z-POWER 30, 1470 kv, max amps 45 outrunner
BATTERY T/P PACK 5S 4600 mah
MOD .07 GEAR with 17 TOOTH pinion
CASTLE CREATIONS 60 amp esc

Well had no troble yesterday setting up the heli which meant doing short hover flights and landings. Set throtle and pitch curves to my taste of flying and had no trouble. To attainn 2200 rpm on the head i had to dail the throtle curve down to 73% from half stick to full power at that point I woulnt get anymore rpms out of the motor. TODAY charged batteries and did some forward flight. About 4 min into the flight 13 feet high going down wind lost all power to the motor. I MANAGEED to do an auto going down wind low in altitude and saved the heli. It wasnt me i am not that good of a pilot but this helicopter is just amazing. anyway can anyone tellme what I did wrong. The motor was so hot you coulnt touch it the esc was smoking hot and melted the plastic it was wraped, in both emited a smell of electrical fire. What did I do wrong and can someone give me a real good recomendation on a motor,esc,battery combo that works well with the gear and pinion I have. I just got a total of 10 minutes total flying and love this heli. I am not into 3-d and I am a mid level pilot on a buget. PLEASE HELP--ANYONE

I'm not familiar with that motor and ESC but my guess is You need to come back a few teeth on the pinion.

Holding back the motor like that is going to increase current and was likely the cause of things burning up.

Hi 48,

I ran an economical but awesome setup on my Logo 500 3D last year. I'd highly recommend it:

- Z-30 1100kv $99
- Used Jazz 80 with heatsink $115
- 15 tooth mod 0.7 pinion $20

I flew it at 2100 rpm and had a ball.

Another good motor is the Scorpion 4020-1100 kv. I have one for sale with 6 flights on it if you're interested. (I upgraded right away to the 4025.)

Get some 6S 5000 mah Zippy batteries and you're all set. I fly FAI style 3D and it would do most everything I wanted last year except for rolling circles.

Keep 'em flying.

That is the motor that I suggested he get for this heli, the Z-Power Z30-1100kv. With a Castlecreations Phoenix HV 85 ESC and the Z30-1100kv and a good 6 cell lipo, 25C or higher, and the heli should do realy well...

you're way overgeared boss,

(18.5V x 1470kV x 17t) / 155t = 2982rpm

5s can't take that heat, 2300rpm on paper (the math above) is a safe start....start with a 13t pinion.

crazy idea...try a Align trex 600 motor on 5s....they're cheap enough to come by used and it should soak up the heat and have more torque than a z30

You may have had something set wrong (pinion) but, this is roughly the 10,000th post that I've read about problems with Castle Creations ESC's. (I'd think it whould have gone into thermal protection) You can skimp on your motor. You can skimp on batteries. You can even skimp on servos. DO NOT skimp on you ESC. The difference between one that works well and one that ... well, doesn't is just too great.

Bend over, grab your ankles, and hand over your wallet. Get a Jazz or better yet get a Jive. You can set either one of these and pretty much forget it. If you don't want to do that, check out the Hobbywing Platinum series. It's not Kontronik but they have been getting good reviews.

You really need a 100amp ESC for 6s or less. I would not go less than 6s. Things are just going to get too hot. A 45amp motor is probably not going to cut it in a Logo 500 either. I'd recommend reading about other people's setups or posting a request for advice on setups. It will save you time, money, and frustration, and you'll end up with a better flying heli.

Good luck!

Ok, I would like to sart off by first saying thank you to everyone that responded and gave me thier advise about the situation/problem I had. After further investigation we found out that the motor that I was using, which I belive is a Z-Power 30 was too high of a kv motor. ( 1470)
With the mod.07 and a 17 tooth pinion it cooked the esc wich was rated at max 60 amps. A solution was found but first a great thank you to all, and especially to Kirk of New Creations RC. We called Hacker motors directly, and we were presented with a new motor that Hacker has been working on for helis. It is the A-40 10L 8 POLE ELECTRIC TURBINE motor. All I can say is WOW what a motor, power, performance, and quality well above anything I have ever had in a helicopter. Best of all, I can still use my 5s packs, and my 17 tooth pinion on a mod.o7 gear and I get 7 and a half minutes of sport flying and after I land evrything is warm but not hot into thermal meltdown like with the Z-Power motor. I didnt have to but the more expensive batteries from a 5s to a 6s and power was more than adequate. If anyone out there wants a great motor try the new Hacker A-40 10L electric turbine motor I am A beleiver with this set up.

I was also told I would have to change a thing if I wanted to fly 6s

Very Respectfully,
Mike Forsblade

What ESC did you end up with? The old one was cooked, right?

You are definitely over-geared.

I had problems with the Phoenix 80 getting a bit too hot for my tastes. It never shutdown or overheated on me, but I needed a way of keeping it cooler.

My solution? See below.

I am using a scorpion 4020-1100 motor with a 15t pinion using a cc80 esc, everything stays warm to the touch for 5 mins of banging. set the motor timing on low. i believe its 3 for the scorpion motors.

This is currently what I am running.

hacker A-40 10L motor
Castle Creations HV-85 amp esc
17 tooth pionion on MOD.07 gear
Thunder power 5s, 4600 mah 22c, 50 c burst lipo

After several flights, I am getting consistently 7 and a half minutes of sport flying, not 3-d flying, with plenty of power. I live here in Beaumont, TX 90 miles east of Houston. We are already at a high 90 degree temperatures with very high humidity......... yuk I am still not used to this weather. I am originally from Colorado. anyways after the flight the motor is warm, the esc is a bit hotter but well wthin the range, and the battery is the hottest of all. But when you consider the heat and high humidity we start the flight with ambient temperatures in the high 90's.

I am very pleased with the results of motor and esc, if there is any deficeincies in this set up i would have to say it is the batteries I am using. But I still cannot get over on how well and smooth this heli flies.

Respectfully,

Mike
