Great distance!! Without a doubt well worth a little over $100+ to double or triple the stock distance. Now my Standard doesn't suck anymore.. I had fun installing the mod and testing how far i could go. But you are right about the RTH. In my case, something caused the app to crash, and at that time i was in RTH mode and had to think quick to cancel it as my bird was attempting to land. Otherwise it would've landed on top of my house or crashed into a tree. I fly from my back yard next to my house and a few trees, there are a lot of obstacles, so i always have to land it manually.
If dont think the app crash was caused by the mod. Thinking maybe it was the recent phone update. Do you also use an iphone?
Actually today i was in manual RTH mode after loosing FPV link, i used the S2 switch to initiate it, so my remote beeping as usual as i waited for the drone to come back to me, all of the sudden the beeping stopped. i looked at the screen, it was still grayed out/not connected. it usually reconnects after drone gets closer to me and picks up the signal. today it did not. so i had to do a manual RTH again, for the 2nd time, and then a few minutes later my drone came back to me. That was kinda strange... Just gotta be careful and think quick.
