Thank you for the replys I have took the advice and went Dbs without boosters "for now" I will report my results when I get it here and installed!! I did fly with my friend yesterday and he has a new p3p and I had the p4, flying at separate times, I started to get weak video warning just past 6000ft after I landed he flew the same rout with the p3p and got weak video warning around 5,500ft. I am in no way saying the p4 has better range I know the are variables and it sounds as the p3p gets better range for the most part. I was actually disappointed in both as we are on a island in Alaska flying over the pacific with no obstacles or interference I figure we should have got more the 1/3 the advertised range! Any way thanks agin and good luck out there.
