There is definitely drag from tip plates and they add weight. That is why I only use them in selected classes. I don't know if they are a good idea for any class. They just seem to work well for me.
One of the few design differences that I use on flat wing models is that there is very little wing offset. With the usual amount of offset used by indoor models some flat wing models will fly around with the outboard wing low.

I thought it was one of life's truths that 'you never get owt for nowt'.
(For the more refined readers 'one doesn't received benefits in life without
some payment is made') I thought that tip plates would have some weight and
drag of their own but perhaps I am out of touch with modern technology.

I must say though, those K777s don't arf go!
