Assuming OP has this case?
If so, it is the same one I have and must admit the transmitter does seem to be an unnecessarily tight fit.
The rubbers of the transmitter have also worn ridges into the foam on mine... I do see that as a minor issue and I suppose it won't get any worse now it 'fits' but find it more frustrating how little room there is for the sticks, they
just fit in when they're in stock position but if you extend them even slightly then they will catch on the foam and be forced into the full up position.
I don't want to have to adjust my sticks every time I fly so will have to cut out some of the foam, not a massive deal but a bit annoying when there is no need for such a tight fit around the sticks.
Again, assuming this is the case you have... I use one of the side pockets for tablet and the other side for props so don't have a problem there.
