HI can i make the range longer with some mods of amazon
Thankyou

I hear tell that those cheap antenna reflectors adds like 30% more range. I dunno, as I just ordered the cheapest one on eBay from China and it will be here in a month or so. Otherwise I am getting 770m through leafless trees. Which is very good in my humble opinion.

I get over 4000 meters with my P3S with RC mods, no AC mod.

Don't buy the Blueproton Arktek range extender.  There is a problem where it doesn't work more often then it does.  I bought one and lost 100 feet distance.
