The Pro doesn't seem to be a good value however. The only difference is the fancy aluminum pieces, and wireless charging base. The Noble NB4 can easily be upgraded to wireless charging, and there are many aftermarket cases that can be purchased. The enhances receivers are cheap enough as well. Most owners I have spoken to don't even own servos capable of running SFR mode. I run SFR mode, but I didn't really find a difference in response between the 1 and 2 way so I have kept it 2 way so I can monitor the receiver battery in my 1/8th scale. The Pro does give a more premium look, however the normal NB4 is already quite premium in feel, and is lighter. Unless you can get a smoking deal on one, I don't think it's really worth the money to go up to the Pro version. I spoke to someone who took both apart, and there is nothing internally they can see that is different from the non Pro version, and the Pro battery works on the NB4, and wireless charging function works just the same on the normal NB4 when using the Pro battery. Regardless, I think you will be happy with your purchase, and you will find the UI to be one of the best out there.
