The logo 6003d is my first large heli but powering this beautiful bird has been daunting. Almost everywhere is seached for a good motor is out of stock. What is going on!!!! Im looking for a good motor for 3d. I then came across the Thunder Tiger Ripper Outrunner Heli OBL 49/08-50H. I dont hear much about this motor. Is it any good and up to the task? I would think since it flys the heavy raptor 620e it would do wonders in the logo. Has anyone tried it? Logo in distress Please help.

The 770kv its listed at IMHO is actually right about where I think it should be for a 10s system. You should get good power on a 13T or even a 14T if you wanted a high HS. Personally I like the 2100-2200 range on my 610's.
We have used it in the E620 on 10s with good results and no failure.
It's just a re-badged z power z50-800, it's not the cooler running "A" variant though.
Good motor for the price, make sure you use the counter bearing with it though.

Thanks fellas, I appreciate the help. I will give it a try.

Can't you grab a Tango in stock for that heli? The 45-08? They are pricey like Neu motors, but I'm pretty sure you can get one. NTM and Ticidytoc, would you agree that a Tango 45-08 would work here?

Which on of these has more power the tango45-8 or the ripper 49/08-50H?

I have no experience, nor have I read anything about the TT motor. Hopefully some of the more experienced guys can pitch in...

The Tango will give longer flight times. The Ripper will make more power...... not that the Tango is weak or anything. Also the Tango 45-07 & 45-06 are good choices too. If It were me picking between the Ripper & Tango I'd go with the Tango 45-08. I never had good luck with the Z-Power/Ripper motors.

I have had great luck with the Z50 series motors (oh, and one Zpower 480th) but you cannot seem to buy them at the moment in the US. I am sure that there are better motors but when you are looking for best bang for the buck, the Zpower motors seemed to fit the bill. If I needed another motor in the Z50 size range right now I would use a Hacker A50-14S. The hacker is a really robust motor and it does not cost much more than the Z50 motors. The hacker may run a tad warmer but the power is just as good or better.

Myself and Nathan were just chatting about this very topic the other night on the phone. If you consider how well a Tango 45-08 moves a Min Air Razor in the air think of a Logo, I think it would be pretty good actually, and very efficient. The razor guys are getting a solid 6-7 mins of sport flying and 5.5 of 3D on 3700mah 10S, this is all on a machine that is about a full pound heavier than the Logo 6003D.....
Hmm Tango 45-08 on 13 tooth might be the ticket.

I'm putting a Hacker A50-14S in mine, something to consider. About half-way between the zpowers and the tangos in the price/quality race. Bobby Smith says it pulls like a truck, I hope so :D
I'll be using a 17t pinion, which should get me around 2000rpm, with plenty of gov overhead but remember I'm flying vbar, so I don't need the insane 2300rpm headspeed.
I ran an A50-14S in my logo 14, as did Shawn at one time. It's an okay motor for the price, decent power, but runs hot.
It's quite ineffecient, flight times aren't that good for the kind of power it makes. My 1915-1y gets the same flight times and absolutely buries the A50 as far as power production.
The Z50-800 is a better choice, more power and runs cooler for roughly the same price.
I'm going to give the 45-08 a try due to the effeciency of the v-bar, 2600 watts actually flies the v-bar 6003d with authority. Normally I wouldn't run a power setup like this that would be considered at the lower end of the spectrum, but it'll be on my back up machine with 10s 3700's and 600mm blades. The main 6003d will still have 4000+ watts to swing 690mm blades.

Nathan

Curious, why would a Tango 45-08 give a longer flight time over a 770kv outrunner ?

I don't have the answer as to why but everyone that tests them says they are super efficient and give the longest flight time. They are also known to run cool, be light in weight (Only 300 grams) and last for many flights.
I was tempted to run one of these on my Logo 6003D but decided to go with a NEU 1912/1Y/H. I feel it's a better combination of power vs efficiently. I'm very happy with it thus fare. My only complaint about it is I wish it was about 100 grams lighter. It weighs just over 400 grams.

Ok I may be opening a can of worms here. My question is money not being an option; what is hands down the best motor in the power to weight ration that will fly the L600?

12-02-2007, 05:53 PM
Actro 24-4 would be my guess

Actro 32-3 will be even abit more powerfull than the 24-4 for sure. At this point what is the very best motor for this machine?? Really don't know, to early to say imho, there are not a ton of options to begin with though to be honest. On 10S here are the ones you can run on the L600.

What is it that you guys don't like about the Hacker A50-14S??
Bobby Smith told me that it was a toss-up between the 32-3 and the hacker...plus in the event of a mishap, getting the actro fixed or serviced for those of us that live in the US is going to be both costly and timely.

The 14pole hacker motors gave these motors a bad rap. They ran hot and spit the main bearing grease out during flight when used in a helicopter. They were really designed for planks running a much lower rpm.
These 10 pole motors run a little warm but they have a different bearing and are fairly easy to maintain. I smacked the nose of my P-51D during a landing tip stall and had no problem taking the motor apart to change the motor shaft. I have read that the 14pole motors are not as easy to get apart.
I have no problems with the 10 pole motors other than the one I shorted out by putting double the rated current through it for about 5 seconds. It did not like that so much... :D
I have not owned a 14 pole Hacker so I can only comment on what I have read and heard about them.
Then 10 pole Hackers are very reasonably priced too.
For the 6s Logo500's and other heli's wanting to run 6s the A40-10L and A40-8L are very good inexpensive motors to consider.

Like I said, it's very ineffecient.
It may use a similar amount of current as the 32-3, so that if you go by an fdr chart it looks like it's in the 3000+watt range. That power isn't getting out of the motor though, it's being turned into heat, which raises the resistance and degrades it's performance. It's one of the hottest running motors I've tried.
It's not a bad motor for the price, but there are several better options.
The A50-14s (yes, the ten pole version) is not in the same league as a 32-3, heck it's roughly the same power as a 24-4, but with less flight time. Same flight time as a 32-3 maybe, definitally not the same power output though !
If you want something US built with good service, the neu 1915-1y gets identical flight times to the A50-14S but kicks the ever living $&@* out of it power-wise.
I've run both motors on the same setup (logo 14), same head speed, same governor %, same blades, same batteries. The A50 gets sand kicked in it's face and loses it's lunch money every time !

You forgot to mention gearing? I don't know what kv the neu motor is but obviously gearing plays a major role. The Hacker seems to do better when loaded up a tad. :)
same head speed, same governor %
Gearing is irrelevent as the motors have different kv ratings, the above statement is what's important.
The different torque constants involved with the differing kv ratings play just as big a role as the actual gear ratio.
What exactly do you mean by "loaded up" ?
I was running 15 degrees of pitch at 2200 rpm, the hacker would drop 200 rpm under full pitch. The neu 1915-1y would only drop 30 rpm.
Same flight times, same mah used.
The 1915-1y drew more peak current, but was more frugal on average current.
In comparison the hacker would draw less peak current but had higher average draw, a classic symptom of a motor that runs too hot.
Fdr charts are useless without logging rpm, you have to know how much power is actually making it to the rotorhead, rather than being burned off by ineffecient components.
You seem to have your mind made up though, go for it, it's not a bad motor, it makes good power... just realize that there are better out there.
