I Started building my reflection last night . I have found no problem with the quality of this kit at all. the hinge setup is tricky but if you take your time, trial fit everting first you should have no problems. so far the hardest part for me has been inserting the z-bends into the clevis, if you don't take enough of the plastic out with the hobby knife they end up to tight, its almost impossible to remove the z-bend i broke 2 .. thankfully you are provided with some extras. as for build time it took 4 hrs to get all the assembly done i just have the push-rods as motor to go.. DAM WORK or i would be finished. Looking forward to finishing it this weekend !!!!
