Electrical what to get?

[Hover Master]

Hello and thanks for looking. First want to make this clear hover master is what I have been called because of what I can do with a Helicopter.
I have been looking and looking at all the different ways to set up a Giant Plane what type of power box or if I can mix or match systems, What is best? I've seen Duralite and Smart Fly I have not made my mind up on what size plane to get but for sure I will use one because of what they can do as to power output and filtering. So I'm stuck on what brand or what gives me the best bang for the buck?
As for the size of plane either a 50 or 85 -100 as it seems there is a gray area between 75 and 100 depends on the manufacture.
Please help me understand about this I want to protect my investment also I do have a Duralite system for my Helicopter it cost so much like 350.00 but when you are flying a four thousand dollar aircraft you want to make sure you have control all the time and not run out of power it really works great and I can fly all day with my 90 size baby.
Thanks for looking
