@Hars: I think 2.0 could be a good idea if you have enough grip...
The plastic is very soft, that's very strange you break these parts on small crashes...
About the trim problem, are you using the aluminum centered servo mount? it is wider than a lot of servo and we also have problem with that, the servo moving laterally in the servo mount...
You have two solutions:
- You can use foam to prevent the servo to move
- You can use a longer screw on the battery side to hold the servo... But to do that you will need to have a metal body servo, at least if you don't want the screw to destroy the servo from the side...
