I have also heard through the grapevine that Sanwa servo frequencies aren't super friendly with the Noble radios, they operate on a separate frequency so there's a slight delay in responsiveness. I personally have Sanwa servos in my 1/12 and I've always complained about how slow the responsiveness of the servo is. After hearing that Mark Rheinard no longer uses Sanwa servos for this similar reason, I've started the quest to make this noble radio as best as it can be.

One of the things that makes Sanwa such a great product is their dynamic servo frequency, dead band adjustment and its ability to sync with the radio. I can't say a single bad thing about Sanwa, their products have won many national and world titles, but on the other hand I don't think FlySky is far off with their NB4 pro, we just need to find the best frequencies and compatibility for the NB4.

Currently, I use a Tekin T-120 & T-180, Protek 160T, all 3 servos seem fast but it's not completely in sync like the Sanwa systems are. I've looked into the MKS servos, they will be my next test servo for the FlySky responsiveness test. Back to my first question, if anyone has gone from the nb4 to the nb4 pro, have you noticed a responsiveness difference? Did it get better or worse? Is it like going from a Sanwa MT44 to an M17? It's easy to speculate and assume the NB4 Pro has the same internals with just a different touch screen but I'm a firm believer in data, it reveals all secrets. If nobody has ventured on this upgrade path then I'll suck it up and take one for the team after I can get rid of my TLR 22 5.0
