Ijust got a 2.6m discus CS ARF with the air brake and retract. The thing is, Idont want to use the air break or the retract. My plan is to simply leave the covering intact over the brake slot and screw a plate over the retract bay. OR maybe even fix the door in the closed position, but then the stock door is a bit flimsy so maybe not.

ALSO I'm thinking this will save some weight, with the absence of the extra servos and stuff.

So my question is; will the plane fly better with less weight or does it even matter?
