This plane would be perfect if the weight could be 4.5 - 5 anything heavier then that is to much for 3d. But It can be done its just harder to do. yours will probably come out tail heavy with that engine I have a saito 80 and 2 oz of lead in teh front of the thing. YA you need to cut the elivator to get the trow on the rudder you need. I weighed it on a friends scale I dont know how (on) it is but it said 5.75. The os may be lacking in power but you can always put in a bigger one.
