As for my 'mistake' in stating "throttle", it doesn't really matter whether it's steering, or throttle...everything I said still applies.

Additionally, if the parts making up the steering mechanisms of both (ie. NB4 & Pro) are the same parts, then that would further confirm everything I said. FlySky, in all probability, does not manufacture all the parts themselves. Like most companies, they would have either outsourced individual parts production to multiple manufacturers and/or they would have purchased off-the-shelf components from multiple manufacturers and/or they would have had OEMs producing parts for them that they designed. Either way, specs of individual components can't always be guaranteed, nor can they be guaranteed that every part from every supplier will 'fit' with every part from all the other manufacturers providing parts.

Every company, from Apple & Samsung, to Ford & GM, have encountered this same type of situation. Look at all the automobile manufacturers around the world that have had to recall cars over the last several years due to airbag problems related to airbags coming from one particular manufacturer. It took years to figure out the REAL problem. It is possible (and very likely) about a similar occurrence was taking place in regards to the NB4...and, since the problem appears to no longer be occurring, It would be safe to assume that either fly sky determined the cause of the problem, and eliminated that particular manufacturer from their parts supply...or, That particular manufacturer may have been removed from the parts supplier list, as they just happen to no longer be needed, even though it may never have been uncovered that the "problem parts" were coming from that manufacturer.

I will admit that there could easily be other possibilities...my theory is just one theory...but, considering similar situations that have occurred with other companies, the probability seems a "higher than average" possibility.
