Hey everyone. Bought my FT-5 R2 kit about 3 weeks ago and just now was able to start assembling it. I haven't made it very far, working on the last bit of the frame, however am not able to get the FT2 plates to be flush with the 700mm beams. I've checked the square of the top and bottom of the frame and still cant seem to get them to align, almost as if they are too long. Any tips?
