RE: Tactic TTX 650
I was at an RC exhibition this weekend. There was a guy there who had a Tactic 650. He wasn't selling them, it was his. He also had an Airtronics SD10G and a JR9303. He spoke very highly of the programming ease of the 650. I held the radio in my hands. For me it feels a bit small in the hands. I did not feel I could get a good grip on it. He agreed but said he got used to it pretty quickly. I am sure I could get used to it to if I had one.

RE: Which (chinese) facctories make various brands of ESC ..?
[quote]ORIGINAL: larrysogla DrMotor, On occasion I also am intrigued as to which factory supplies the product offered by the retailer.................in a way it is useful because as you pointed out the Hacker 70A ESC is over 100 bucks($109.99) and the Turnigy 70A ESC is $28.73...............and the question is..................(HOLD ON TO YOUR HAT FOLKS)....................ARE WE REALLY GETTING ALMOST 4 TIMES THE VALUE when we pay $109.99 instead of $28.73.................I work in the car rental industry and our rental vehicle prices fluctuate depending upon market demand..............sometimes the difference between a high demand season compared to a slow season for the same car make and model is over a hundred dollars a day. The car rental industry, the airlines, car dealer, RC Hobby retailer all will try to charge as high as the market can bear............this includes re-branding the same item to raise the perception of higher value when deep under the skin it is all the same product but the business owner is able to charge higher because of PERCEPTION OF VALUE...nothing more(same product, same model, same function). Now in the case of Apple Inc. they have a very high standard of quality and are very demanding from the supplier to maintain that high level of quality and therefore Apple is able to command premium prices. In my personal opinion although Apple has a very high quality level IT IS STILL OVERPRICED. Perception of value allows Apple to price it's products very high. It is probably not too far away in quality as the next competitive computer company but the perception is that Apple has a higher quality therefore they will charge more. 'Nuff said. [/quote] The value in the apple products is not in the hardware, thought there is a certain amount of enhanced value there, it is in the software and, to a large extent that is what you are paying for. It is pretty easy to let others do the R&D, then steal or reverse engineer their work to make a cheaper product. And that will happen in the market and consumers will vote with their dollars as to whether they want that leading edge stuff, the similars or the clones. There are also things that are put into products that are not related to where they are made. Quality testing after manufacture, support structures, customer service. These all cost and those costs are layered on top of the cost of mfg. Hey, I like to buy stuff as cheaply as I can but I often do not buy the lowest cost product out there because I want that customer service and I want to support that innovation that brings me newer and better products. All technology eventually falls to the commodity level as volumes rise and features become standardized. Competition drives down the price. I have purchased from HobbyKing and from Tower. Tower gives me GREAT service and the stuff I buy works. And if it doesn't they replace it so fast it makes your head spin. HobbyKing's service has been aweful. But for some items I buy from them. In some cases I buy two since the cost of warranty service is so high it is cheaper to buy two and throw one away if it doesn't work. So, knowing where things are made is useful information, but it is not the whole story of the value received.

RE: Which (chinese) facctories make various brands of ESC ..?
I will not dispute your postings. I have no info to prove you wrong. However, coming from the computer industry, know that common components are used in a lot of computer systems. But the top line companies spend a LOT of time and money testing and certifying components. A disk drive, for example, can come from the same factory for many makers, but the top companies will have tested the firmware on the drive and in many cases rejected it, insisting on changes or fixes. Drives will be qualified with controllers and OS revs. The smaller companies don't have the resources to do this, so they sell cheap and hope for the best. No disrespect intended but it costs a LOT to provide the level of support the top companies provide including testing, stockign parts, documentation and training of their staffs. That cost is reflected in what they charge. So, yes, two disk drives can come out of the same factory, but the customer experience can be quite different. So, I would imagine, it would be with these components too.

RE: Which (chinese) facctories make various brands of ESC ..?
DrMotor, I have read a number of your posts in the past. You seem to be very interested in where things are made. That is fine. But you do not cite a source for your information. How do you know these devices are made in these factories? Are there statements by the brands that you mention that their goods are made in these factories? In fact, I really don't care which factory makes them. I only care about the features, function, reliability and overall quality of the products I receive. It is quite possible to make several brands or products in the same factory, each to a different design and quality level. Even if 10 different ESC come out of the same factory, that does not mean they are the same, or even similar.

RE: EVERYTHING YOU WANT TO KNOW ABOUT ELECTRIC FLIGHT
Ray, This thread is a book. I presumed you had read it before coming to ask these questions. The book is about understanding electric power systems. Perhaps, before you go any further you should read the book to understand what you are working with. Here are the challenges. I have no idea what motor that is. If it were a hacker it would say hacker, like this one: http://www.aero-model.com/Hacker-Brushless-A150-10.aspx I don't even know if it can or should run on 44 volts I don't know the kV rating or the max amps, so I have no basis of a recommendation other than to say it should be something smaller than what you have now in order to not overload your ESC. I have no idea what the motor can take but I know your ESC can't take over 200 amps. You mention, "the recommended size Xoar 27 X 12 wood Link this word and every other one like it in our forum to YOUR Website! prop spun in the proper direction and all seemed well," . Who recommended this prop? What was the recommendation based upon? Or are you saying that would be the recommended prop for a Hacker motor, if this were a Hacker? The motor you have may have no relationship to a Hacker motor and have nothing in common with the Hacker. If the kV rating is different than NONE of the Hacker specs will apply. Sorry, I wish I could be more helpful. Perhaps you should start a discussion in the giant scale section. Someone there might recognize the motor.

RE: EVERYTHING YOU WANT TO KNOW ABOUT ELECTRIC FLIGHT
[quote]ORIGINAL: RAYGIB I need help! I've converted my Hangar 9 35% Extra 230 to electric power. The motor is believed to be a Hacker A150, which is rated at 8000 watts, 44.4v and 200 amps. I have a 200 amp Turnigy Monster ESC and 4 Turnigy 5000 mah 6S LiPos in a series parallel conbination delivering the 44.4+ volts and somewhat over 200 amps (measured with a 200 amp ammeter with a 75mv shunt). It flew once for under a minute before the power died and dead sticked in. However, power was there to taxi back. Holding the plane down for testing, with the ammeter in series between the batteries and ESC, the set up will pull just over 200 amps at full power, but only for 20 or 30 seconds before it shuts down uncommanded. The motor gets quite warm in that short time. Even when started from ambient temperatures sometimes the motor will drop off line at only 70 amps when the power is coming up. The voltage from the 4 LiPos never drops below 42 volts, even under full power, so low voltage would appear to not be the problem, although anythings possible. If the power is brought up very slowly, full power may be attained, but it usually doesn't last more than 30 seconds. Anyone any ideas on how to fix this short of putting the DA 100 back in? [/quote] Believed to be a Hacker A150? You don't know? Which model of the A150? And if you don't know what it is where are you getting the specs from? Do the math. 8000 watts at 44 volts is 181 amps. You are overloading the motor with 200+ amps. 200 amps at 44V is 8800 watts, which is 10 % over the motor's rating. Assuming this is a Hacker A 150, it is rated to 9000 watts/204 amps for 15 seconds ONLY. And the recomended ESC for that motor is a 220 amp ESC. Hacker motor specs: http://www.hacker-motor-shop.com/e-vendo.php?shop=hacker_e&SessionId=&a=article&ProdNr=37200006&t=3&c=35&p=35 Depending on model the motor can handle 150 or 188 amps. Recommended prop is 27X12. What prop are you using? You say you are pulling over 200 amps on a 200 amp ESC. You are overloading the ESC! And you wonder why the system is shutting down? If it did not shut down it would catch fire. I would bet there is a good chance you have damaged the ESC. Whether you have damged the motor I can not say but this is not a good combination of components. You could prop down to reduce amp draw. that might resolve your problem. You don't say what prop you are using.
