Anyone seen this new NOVAK GTX esc in action? Any comments will be appreciated. Thanx :thumbsup:

Novak's Smallest & Most Powerful Racing ESC Ever!
Think small. Really small. Now think powerful. High-tech. Rugged. Durable. Orange. These are all accurate ways to describe Novak’s newest, smallest, and lightest speed control ever: the GTX, the new benchmark for programmable racing ESCs. Go ahead, measure it and compare it to other ESCs, Novak or not, and you’ll learn that the GTX is one of the smallest, lightest, and most powerful competition ESCs currently available.
While new to the public, the GTX has already claimed several race titles (including current IFMAR 4WD World Champion!) thanks to world-class drivers having used it in events across the U.S. with victorious results. Among its wins are World and National titles, as well as champion of prestigious annual races. An impressive debut, indeed. Here are just a few of the racers and their titles who were GTX-powered:

Ryan Cavalieri 2003 IFMAR 4WD World Champion
2004 Reedy Race Champion (Open Modified)

--------------------------------------------------------------------------------

Mike Blackstock 2004 ROAR Carpet National Champion (1/12 Modified)
2003 Cleveland U.S. Indoor Champion (Modified Touring Car)

--------------------------------------------------------------------------------

Jukka Steenari 2004 ROAR 4WD Modified National Champion
2004 Losi 4WD Off-Road Champ

--------------------------------------------------------------------------------

Brian Kinwald 2004 Cactus Classic Champion (Modified Truck)
2004 Speed World Cup

--------------------------------------------------------------------------------

Ralph Burch 2004 Snowbird National Champion (Touring Car)

--------------------------------------------------------------------------------

Greg Hodapp 2004 KO Grand Prix Champion (Modified Touring Car)

Thanks to sophisticated new MOSFET technology, Novak was able to design a significantly smaller, lighter, and more powerful ESC than ever before (1.11” x 0.86” x 0.60”; 0.64 oz). The best part is that the small size was achieved without sacrificing any of Novak’s signature features such as One-Touch Set-Up, Polar Drive Circuitry, and Radio Priority Circuitry. It also has Digital Anti-Glitch Circuitry, and is the only programmable racing ESC with built-in Thermal Overload Protection and a 36 Amp Schottky Diode. So not only is the GTX extra small (it’s even smaller than Novak’s XXL receiver), it’s packed full of features, power, and built to withstand the rigors of competitive R/C racing.

Equipped with Novak’s Variable Throttle Step Technology, which delivers 1300 discrete steps for both drive and braking, the GTX delivers incredibly smooth performance. The 100% digital, microprocessor-based ESC has ultra-smooth throttle response at all frequencies (up to 11 kHz), as well as the quickest response to change in transmitter signal (<60µS); all this from the smallest size and lightest weight competition ESC in any class!

Part of the GTX’s unique makeup is that it is built with six layers of gold-plated powerboards, which help increase its power-handling capabilities. Externally, the GTX also features low-resistance gold-plated PCB Direct Solder Wire Tabs. When used with the included Novak Super-Flex silicone wire, users are assured of the lowest possible voltage drop, as well as easy and convenient power wire and power capacitor replacement. The GTX uses the strongest BEC (6 volt/3 amp) available, which allows faster servo response and better torque-holding capability. For a perfect fit in any vehicle, a user-replaceable combination input harness/power switch that comes with both a long and short length input harness is included so you can get a custom looking install without having to figure out what to do with the extra wire.

It’s hard to believe, but within the tiny GTX case resides 7 throttle programs that are pre-programmed for nearly every driver, application, and track condition. For advanced users, or people who like to tune everything, Novak has incorporated a 7th program that can be customized by using the One-Touch Set-Up button (no external programming device required). Four different color LEDs help make programming even easier by providing prompts. The 7th program offers similar settings to the other six programs, but allows you to adjust Drive Frequency, Minimum Drive, Brake Frequency, Minimum Brake, Dead Band, and two different types of braking: standard Constant Force Braking or Drag Brakes.

The GTX was designed with the competitive R/C driver in mind who demands not only a small, lightweight ESC, but one that can deliver superb performance. The GTX delivers all of the above and more.

Oh wow that thing is small. Weve seen many small escs on the market. The LRP Quantums, GM V series, that MTronics Cubic thing, Futaba, Kenyence.......IMo, its all the same stuff, a feature here is all that makes them different. A big thing will be price.....hopefully it will drop.

Hey Fish I believe the top 2 19t cars at the last focar race ran Novak speedos if this thing is anything the GT7 then it will be the bomb. If the price comes down I'll buy one.

Does it burn up and quit like the GT-7,I wont buy one after going through 3 GT-7. Especially after the last one had only 8 minutes of racing on it. NOVAK has alot to prove if they want this new speedo to sell,test drivers dont sell merchandice,product reliability does!!

Phil I am curious about something on this last one did you run that diode that comes is the wires?

I'm going to take a wild guess here that you didn't use a sckotty diode. I've only seen 2 stop working and none burn up. I've talked with Charlie from Novak before and if you burned it up while it was hooked up correctly I'm sure he would love to see it, to see if it was defective.

Believe me it was hooked up correctly and also had the diode. A speedo does not burn up after running several laps if it was hooked up wrong,nor is it slow out of the box if there isnt something wrong with it to begin with.I have run Novak speedos off and on for years with no problems until the GT-7 came out.Hopefully the new product doesnt carry the same problems.

Novak has been testing this one for quite some time now guys. I think after the early problems with the gt-7 they decided to test longer with this one. Novak has always had a solid reputation in the electronics. I would look for the gtx to be a solid esc right away.
