whats up,i'm in the market for a new esc i am debateing on the gtx or gt7.i have a budget thats why i'm looking at the gt7.the big question for me is that the gt7 only takes 6 cells.could i run a 7 cell pack without frying it or is that a crazy idea.i race a 6 cell class now but you never know what rules the club will change,they like suprizing us on short notice

I would not take a chance on using a 7 cell pack on a GT7. I know that it is a very high quality esc, but for that much money i would not risk it. Especially since you are on a budget.

Short of maybe with a brushless setup, there's really NO reason to run seven cells on a club racing level. Even if they did institute a seven cell rule, you'd be better of with six cells. And you'll be fine with the GT7 as well as the Cyclone or Cyclone C2 which were Novak's top models previous to the GT7.. all of them are quality esc's and the older models *REALLY* help with that budget issue. Check out Novak's website, they sell refurbished esc's at very good prices, usually right around or less than what the same esc would be elsewhere (ebay?) and the Novak refurbs come with a warranty.

yeah thats exactly where i was looking 80 bucks for a gt7 or 150 for a gtx the cells is what i was looking at & i noticed that in the spec chart it says it doesn't have thermal overload protection but in the feature page it says it does, does any body know which one it is. i'm waiting for a reply from novak now.i still think i'll get the gt7 for the bucks just found out i'm getting a weeks pay for summer bonus.the hell with vacation lets race!!yeah i'm going to tell my girl that.but i can find a 100 for r/c

Even though it is older I would also second the Cyclone or the TC version. Both of wich are great speed controls that I have used and still have.

It depends on what kind of racer/spender you are. I'm running anything from a brand new GM SX12 to my old school novak cyclone TC and Atom. They are all good! You want a brand spanking new, top of the like speedo, I ain't going to stop you. GTX's are great speedos! GT7's are good performers but I heard and seen some nasty things with those cause apparantely there ARE some lemons in the batch(different versions of it). However, I LOVE the cyclones(I had 3 of them; regular and 2 TC's). They are the best speedos that novak ever came out with. They feel very robust physically(hold one and it feels solid, my SX12 feels cheap! despite being expensive). And they work great! None of that "you will blow it if you set it the wrong profile or current" bullcrap! Guess I'm stealing a thread here and venting at the same time, but I'm serious. I race stock and 19T, sometimes mod for kicks. With those small tiny speedo's from GM or KO, you can blow them if you have it set wrong(mod motor with the stock profile). But NOT with a cyclone! Works fine even with the wrong profile, works great with the correct one!...

tem ,i didn't think the profiles were limited to certain motors i thought all the profiles worked on any motor. is what you are telling me true??.i know run a super rooster which has a very low frequency an electronic engineer told me the higher the frequency the better for me, especially when i race an oval carrying alot of rpm & not needing to much low end torgue.i run low turn motors & i don't think i'm seeing thier full potential.any input on that. thanks for any help

I said you CAN use the wrong motor for the profile with the cyclone and it still works fine. But on some other brand/model speedos (ie my new GM SX-12), the default profile is only good for stock racing. But if you put a mod motor in it it will get extremely hot and even blow because it's exceeding the current limit of stock profile. My SX12 gets pretty warm with a 19t spec motor on stock profile. It even feels less punchy than the Cyclone but I have yet to learn how to set it right but I know its capable of doing better. In my experience, you can beat the crap out of a Novak Cyclone, and Tekin G12 and they keep on ticking! I'm an electrical engineer as well(specilization in power systems, robotics and automation) Different frequency will affect efficiency and power response(ie. punch) but dependent on motor type. In R/C typically lower frequency will be more punch and higher frequency will have more run time and put less load on the comm (you probably seen or heard that from someone else first). Lower frequency also means hotter motor. Aside from frequency, current handling is also important in R/C, this is where they Cyclone (and a Tekin G12 I owned) really shines!

tem my buddy had a g12 he put it through some heavy abuse with a stock club motor but it eventually smoked out & litterally melted on the starting line(flames & everthing).as to the gt7 i printed & read the manual off thier web site & it did not say anything about certain profiles for certain wind motors they only gave examples of what type of racing they may best suited for.the rated power handling is twice as much as my super rooster so i can only see more performance in my case.thanks for the tips.don't over gear your tekin to often like my bud or you'll be reaching for a fire extinquisher(ha,ha ha,)
