I understand that you can only use 2.4 Radios with Novak Brushless systems . Is this the case for other manufacturers as I currently still use a sanwa gemini system

A mate is running a Novak brushless Losi 1/8 and he had problems and was advised by Novak that the systems were designed to be used in conjunction with 2.4.
If this is not the case and I could use my sanwa system that would be very good news. |

I know the Novak HV systems can cause problems with AM radios, my E-Revo was basically unusable with the stock AM radio, no problem with 40MHz FM though.

Novak do 2 versions of the GTB, the spread spectrum version is intended for 2.4g systems only I believe.
I have the non spectrum version and it was fine on 40mhz, still fine now I have 2.4g! |

Me and some other have had problems with Novak and 40mhz
Now the system is installed in my 1:12th scale and I don't have it any more. (shorter range I think).

Its true, however you have to look at the product box and on mine it said to be used only with the Spectrum system. they do a standard one for standard radios as well.
Still it works well without glitching with the Futaba 3GR synth 40mhz radio even tho Novak did recommend me not to use it unless I had a spectrum.

In the end, the information that gets passed from the receiver to the ESC is exactly the same, careless whether it is 2.4GHz or 40/35/27MHz, what may change, is the frame rate at which the data is passed from the receiver to the ESC, some of the new 2.4GHz systems are very fast, so the issue may be that the ESC is designed to receiver the higher responce signals, and it gets confused maybe. But that is just daft engineering.

DCM - you got it in one, Novak said its been specifically designed around the Speccy system due to the way it works. I agree with what you say though and should really design the esc to recognise what its connected to.

no, design the ESC to accept the higher frame rate, but also see the slower systems, it isn't difficult.
In the end, it is only reading a servo signal. But then, some of the HRS systems won't work with an analogue servo, as they can't accept the higher frame rate. I just think Novak are just trying to cover markets and not accept maybe small flaws in design.

Possibly right there. Explains why my servo is putting out more steering with the Novak compared to the Tekin RS Pro with the same receiver. The servo I was using was megga slow in my 2wd until I bunged in the 2.4 Novak esc (evena though my system wasnt) Mind you maybe Im just lucky that the 3GR receiver hasnt been affected and it still works.

According to Novak the difference between the GTB and the GTB Spread Spectrum is that the GTB SS works at a higher frequency, this can cause RF interference problems with AM/FM radios, so it can only be used with 2.4GHz radios while the normal GTB can be used with any radio. It's not related to the servo signal side of things, either GTB version will work with both normal and high response radios.
If your servo worked better with your Novak than Tekin, there must have been a problem with the Tekin's BEC output, it shouldn't have affected the response of the servo otherwise. The Novak HV-Max, which is probably what toooldskool's friend was using in his Losi 1/8th, is a different ESC which also has problems with AM radios because of RF interference. |

Toooldskool started the thread because his friend had been told the Novak in his Losi 1/8th would only work with 2.4GHz, I assume this was a Novak HV-Max not a GTB. |

Is this just the case with Novak or can it happen with other systems like SP/Losi/LRP??
Ive just got back into rc and im building up my gear and dont want to have to change to 2.4 right yet! ![]() |
