After reprogramming and calibrating everything seems to work ok. I can't understand what I did wrong the first time. Thank you very much and I can also confirm that the FW2.0.101 (FCC Version) version has no problem. at 250 meters I did not face any problem. Thank you very much! ! !

Wow fantastic update! Cant wait to add the GPS module to thy crawler and everything else added is brilliant too. This was a necessary release tbh because at more than double the price nobodys buying the pro relatively speaking compared to the NB4. Really glad they came through.

[@WTFRCCars]

You would be surprised at how well the pro is selling even at £399 it's still way cheaper than a futabe or sanwa that can't do anywhere near as much :)

[@ninthislandrc]

As usual...and, as everyone watching your channel has come to expect...excellent video, and excellent info. I would, however, like to make one suggestion related to naming files. When naming files using dates, is always best to go in a year-month-date format, 2-digits for each (4-digits for year is also good, but not necessary). This is because, not only is that the format that all PCs recognize...but, it also makes files the easiest to find. I even do this in naming folders (usually that format, followed by an actual name, such as "23-05-15 - NAB Show 2nd Day"). Just a 'suggestion'...but, a very smart one. Again, thanks for the info. So far, I'm off work tomorrow...so, I think I know what I'll be doing for at least part of the day. 🤙🏼

[@WTFRCCars]

Glad ya like it, as for the naming I just have mine set to show by date created so the newest is always where it should be :)

Hi. Can you help me. I have a NB4 but i cant calibrate my esc’s to have a brake. All skyrc esc. Ts50 Ts120 and Ts160

You will likely have to slow the transmitter down so the esc can keep up, do this by setting the servo speed to 333hz and then calibrate the esc again :)

thanks for the follow-up! The rx are 2.4GHz DSM2 that I have been using with my old Spectrum DX3c TX. I think i got them from hobby king years ago. I have several of them and it would be great if I could still use them with the nb4. Thanks for the reply!

whats the difference between standard and fcc? also en vs euro?

On nb4 there is no EN or EU, the + and pro radios are EN or EU and thats just the market they are sold in but you have to match the updater version to the radio you have, Standard is normal tx power longer battery life and FCC is higher tx power only legal in USA and slightly shorter battery life.
