If you enjoy autonomous flight a good use for the P3S is Litchi missions. The Standard is lighter & offers 2-3 additional minutes of flight time over a Pro/Advanced, plus it is a lot less $$ at risk.
Ok now that is what I wanted to hear OP.. Now I feel good about buying a P4.. I was on the fence before because of all the posts about the poor range. I do mostly distance flying with my stock P3p (windsurfers only) I've gone 3.1 miles out with full signal and video (ran out of room) and 8.1 miles total flight distance. I wasn't going to go for the P4 if it couldn't at least equal those numbers.. So your post is really encouraging. However it seems battery time might still be an issue. I see some guys are getting comparable distances but in about 15 minutes.. So the P4 is really fast (in sport mode) and can cover distance quickly, but still is maybe limited on batt time.. Nevertheless I will be buying a P4 and keeping my P3p. Now the only question is what to do with my P3s.. I bought it at $500 less than a month ago, have only 10 flights on it, in perfect condition. The best distance I got with it using a windsurfer was 7,000 ft out before losing signal and video completely.. I was thinking of selling it but now I hear that they are going for $300 brand new? Oh well..
