Does the HW OTA provides more adjustment than the Program Box? It seem both needs to be connected to the ESC at some point. Just wondering what is the major advantage of one over the other. Is the connection of the OTA reliable? If you were to buy again, which would it be?

its not more adjustment its more ease of use
the program box you have to click through each option where the ota lets you hop around
i like using the OTA alot for copying profiles from one esc to another and making small adjustments while i can see all the options and not have to think ok what one is next or what was previous
i just think that using my phone to modify parameters is exponentially easier then the box.

however, if youre a set it and forget it type of person the box is probably fine.
i like to change drive frequencies, softening values etc often based on track conditions

It has a lot more adjustments you can fine tune it more than with the programming box also you can use the customized functions

OTA is a no brainer.

ah i stand corrected...havent used the box in so long i didnt realize you couldn't access everything

Ok thanks guys that makes sense. Is there any connectivity issue with the OTA. Have any of you ever have difficulties connecting? I can imagine it would be frustrating if the connection is hit and miss.

via bluetooth never had an issue takes about 10-15 seconds to load up

Was just about to ask this same question.
