Quoting Luke Skywalker
This is quite a nice version of the famous Snowspeeder. And the problem with the angle of the gun is either the smaller one is 1 stud to low, or the base plates are not connected firmly and one is standing up a little. If neither, than I give up.
NO NO NO.. hahaha u got it wrong. i WANT it to be like that. and it is that the front is a stud low. but i wanted it to "hug" the wing. at first i wanted it changed but i like it. without that angle, i can only put spacers on the gun and not gears. understand. and it seems too tall when it is even. but at least u noticed it.
