MAGNETIC INDUCTION SERVO (PROBLEM OF QUALITY) LTAIR / HK
such good friends, here I bring news that many expected, though not the desired, I've been doing these tests to Europe and the manufacturer http://www.ltair.com/en/ servos that are the same as selling hobbycity, I have ordered several of these servos in my trex 600 nitroCABEZA KASAMA / trex 600 flybarless SK 3600, I must say that the quality of the gear is perfect, and apparently have a very good quality, not so much as mount some are missing the board that makes tight, I mean that tube many problems in the heli tail servo 760 using us, it was impossible to stop making fish tail, he sent the vineyard to the manufacturer, He said that the MOVEMENT WAS NOT SIGNIFICANT , other tests that were conducted in cars were more of the same at 8 or 9 races were burned engine, talking to the manufacturer told us they were going to change the engines to solve this, but after almost 2 months of waiting and trying to help improve the product, we gave up, well this is my experience THEREFORE NOT RECOMMEND and here I leave some photos

Next to the last close-up picture of the bottom side of the printed wiring board. I seem to see a couple of unsoldered pads with component pins in them. Just to the right of center. Perhaps a bit of a quality control problem here.

Looks like a six pin connector of some sort. Four of the pins have poor solder joints, too much solder, not enough heat. The two unsoldered pins, well, not enough solder OR heat!

Some of the surface mount parts aren't that well attached, either.

I'd be willing to bet that a few minutes with a hot soldering iron, a microscope, and patience, that servo would come back to life and probably work very well.

Not that I'd want to have to do that with every bit of electronic RC gear I purchased....

Today I have received a few emails, 1 blue arrow and the other importer, person to appreciate it, and wanted to apologize if I offended anyone, that I write is what I feel, the tests were conducted with the helicopter I personally realize the impressions which he described and those made by car were made by the importer with different cars and the results are as described and the cumin to the factory, so I'm preson either outside and these comments are only mine,
email attachment here, I hope not to bother explaining blue arrow servos improvements, I hope all these prove to have reliable servos cheaply and amply tested, greetings and thanks

Dear polizonteoscar,

We have found one new sepc of coreless motor , this motor comes with smaller operating current ,so the motor life will be longer,and servo will be more durable.

Merry Christmas and happy new year eve to you!

Looks like my Arizona regulator. I did clean it up before I dared to use it. Also reminds me of my old Century VII transmiter.

good because I get the new servo I am attaching some photos here, has a very smooth very good, the unic problem I see is that by putting it to 6 volts move much, which at 5 volts is perfect as any futaba 9254 9256 bls251 etc.
so I decided to leave at 5 I've only done a test flight, but the truth is that it has been perfect, more dire and try more things as a greeting

Pull the circuit board out and take us a picture of the "magnetic induction" part. A nice guy reminded me that Proline once experimented with an optical pot using a disc with a tapered slot. I do remember discussing this with some guys one summer afternoon in about 1975.

I have never ordered anything from HK even though i have been tempted a time or two. Most recently when I saw these released. But then someone will post pics like this and I am glad that I havent. I am with dkshema on this one, doesnt matter how cheap it is or how well it could work. I dont want to have to crack open every piece of electronics I buy. I have seen better soldering jobs from someone who had never used one before."There is a fine line between cutting edge and bleeding edge.."
