ZTW Mantis Series ESCs are designed for both beginner and advanced modelers. Their performance and stability have been approved by distributors and pilots around the world. Mantis ESCs feature a compact size, light weight, super smooth start up and throttle linearity, multiple protection modes, solid BEC output, and more. All these features make Mantis Series ESCs the perfect mid-level speed controller for park flyer, sport, and aerobatic pilots.

ZTW speed controllers are one of the most widely used and trusted speed controller brands available on the market today. They are sold under many different brand names, but we choose to purchase direct from the manufacturer without rebranding so that we can pass the savings on to you. ZTW controllers represent a new generation of brushless ESCs using advanced microprocessor technology. They are designed and manufactured with high quality components which provide exceptional reliability, low internal resistance, and a smooth, linear throttle response.

This programming card is specifically designed for the ZTW Mantis Series electronic speed controls.

HOW TO USE THE LED PROGRAM CARD:
ZTW Program card with LED display is easy to use and convenient to carry. All of the programmable functions are shown on the program card.
Turn on the ESC. Remove the signal wire and plug it into the top-socket on the program card, wait for 2 seconds until the LED is on.
If ESC is not connected with the batteries, the program card should be connected with other power supply, the range of power supply is from 5.0V to 6.3V.
Press the button ”Menu” on the program card and circularly select each programmable function. At that time the number of programmable function will be displayed on the left of the LED, the current value will be displayed on the right side. Then press the button “Value” to change the value and press the button “OK” to confirm. At the same time the Red indicating LEDs of both program card and the ESC will blink. Turn off the ESC, the modified settings will be saved in the ESC`s memory.
Press the button “Reset” to restore the default settings.

US bitcoin futures start trading on CBOE, a week ahead of futures rollout at rival CME Group; bitcoin’s price climbed ~8% in first seven minutes of trading

décembre11

The first bitcoin futures started trading Sunday, sparking a swift run-up in the price of the digital currency as the exchange provider’s website experienced outages from heavy traffic.

Trading of the hotly anticipated U.S. bitcoin futures began at 6 p.m. Eastern Standard Time on Sunday on an exchange run by Cboe Global Markets Inc., while its larger rival CME Group Inc. plans to introduce its own bitcoin futures a week later.

The bitcoin contract expiring in January opened at $15,000 and spiked to $16,660 within the first six minutes of trading, an 11% surge. Prices later dropped, then rebounded, and the contract was recently trading at $16,900, according to data from Cboe. About 1,000 contracts changed hands in the first three hours of trade.

The exchange halted trading for two minutes at 8:31 p.m. due to volatility, said a spokeswoman for Cboe. The exchange operator can impose such halts after a 10% price swing.

Bitcoin itself was at $15,937.05 around 8:45 p.m., according to CoinDesk. The price climbed 8% to $15,740.25 in the first seven minutes after the futures contract started trading.

Interest in the futures caused problems for Cboe’s website. “Due to heavy traffic on our website, visitors to www.cboe.com may find that it is performing slower than usual and may at times be temporarily unavailable. All trading systems are operating normally,” a Cboe spokeswoman said.

The launch of the bitcoin futures represents a milestone for the digital currency. But the new market could be roiled by hacks, technical snafus or manipulation schemes.

The virtual currency bitcoin continues surging to new highs as a frenzy of investors get in on the action. WSJ’s Paul Vigna explains what you need to know, and how to invest should you want to join the mania. Photo: Alexander Hotz/The Wall Street Journal.
One risk, critics say, is that the underlying markets for bitcoin are largely unregulated and have a troubled history. Mt. Gox, once the largest bitcoin exchange, collapsed in 2014 after being robbed of more than $470 million of bitcoin. Other bitcoin exchanges have faced criminal charges of money laundering.

“The Bitcoin cash markets are immature and hardly seem the epitome of robustness,” Craig Pirrong, a finance professor at the University of Houston, wrote in a blog post.

Bitcoin has been the best-performing asset in financial markets in 2017. The launch of bitcoin futures comes as a confluence of economic, financial and cultural developments has spurred a rise of more than 1,500% this year in the price of the digital currency.

But the futures’ launch has cast a spotlight on the market’s shaky foundations. Bitcoin exchanges were plagued with glitches in recent weeks, even as the price of the virtual currency soared to records—passing $17,000 on Thursday, from just $968.23 at the start of the year, according to CoinDesk.

For their futures products, Cboe and CME are betting that a handful of bitcoin exchanges are sufficiently reliable and trustworthy to support a derivatives market.

Still, recent mishaps have raised questions about whether bitcoin exchanges are ready for prime time. On Nov. 29, heavy trading sparked by bitcoin breaking through $10,000 the previous evening caused outages at Bitstamp and GDAX, among other exchanges.

All five bitcoin exchanges working with Cboe or CME have taken steps to embrace regulation and anti-money-laundering laws. Their representatives said the industry had matured. “Exchanges that weren’t up to a certain standard, due to incompetence, have died out,” said Bitstamp Chief Executive Nejc Kodrič.

Some critics warn that unscrupulous traders could push around the price of bitcoin on the bitcoin exchanges, manipulating prices in the underlying market to reap profits from the futures.

“Bang-the-settlement type manipulations are a major concern,” Mr. Pirrong wrote. “Relatively small volumes of purchases or sales could move the price around substantially.”

The bitcoin exchanges partnering with Cboe and CME account for a narrow slice of the market. That means a manipulator wouldn’t need to move the price of bitcoin world-wide, just on a small number of exchanges.

CME’s four partner exchanges together handle roughly 10% of daily global bitcoin volume, according to coinhills.com, though they account for about a third of bitcoin trading in dollars, which CME argues is the more important measure.

CME says it has taken steps to combat manipulation. The index that underpins its futures contract is based on trades executed over a one-hour period each day, with anomalous trades tossed out. CME also is working to add more bitcoin exchanges to its index, a CME spokeswoman said.

Cboe’s contract uses a price determined in a daily auction at Gemini. Gemini data show its daily auction volumes this year have averaged $1.3 million—a drop in the bucket of global bitcoin trading, which runs into the billions of dollars daily. Gemini’s auction process also has failed to produce a price several times in recent months, on lightly traded weekends or holidays.

Gemini says its auction will gain in volume as Cboe’s bitcoin futures contract takes off, and even if the auction is small relative to global trading activity, it offers a useful measure of bitcoin’s price at one point in time each day. “Auction mechanisms are tried and true,” said Gemini President Cameron Winklevoss.
