I bought the HS120 last Spring. Cut my teeth on it and (trumpets) have never had to replace anything. I have never put the prop guards on it. I can handle it pretty well. I am looking to upgrade but it seems not only would I be putting out for a new drone but a new phone? Apparently my Premier Pro LTE is 32bit, or something called armv7? and not armv8. But it works with the HS120. Is there any HS upgrade that would still gladly use my phone as is? Thanks in advance.
