Nothing wrong with having multiple transmitters either. One stock, for ease of lightweight, compact, transport and deployment out of a standard case, and second one with DBS-02 boosted for long range, when you don't mind the extra hassle, size, and weight.
There's nothing wrong with it but let's not forget the price of a remote is almost the cost of a whole P3A package on a good day. I think it's unrealistic to have two remotes in most cases. However multiple antennas to swap out is realistic. The main thing is that the mod changes your entire approach to being flight ready and does add a level of inconvenience that isn't there with stock, especially when adding amplifiers and a battery into the mix too. But this thread is about long range and mods to do it so that's a completely accepted part of it. Having done remote mods, I'm just adding some food for thought for people that are considering doing it without realizing the actual commitment to doing so. You don't usually un-mod back to stock even if you find it's not your thing. You live with. Just be aware, is all I ever suggest to people interested.
I wouldn't touch that or anyone's cheap price remote, personally. If you lose your bird it could be a remote problem too. I'm talking about nib remotes from authorized dealers. Last time I looked they were around 600 bucks.
