Just got my package and it had alot of goodies in it .The inner and outer shafts, battery holder, skids, and a neat heli pad. The workmanship on all the parts are first rate.All parts go together as stock no problems at all. Because the outer shaft is so long, the only different thing is the lower bolts in the lower head go thru the holes in the shaft instead of the upper holes as in stock..Got it all changed over in no time and took to the air. No trimming from the setup I replaced. I went out side in good winds and threw it around. I don't think you can hit the blades together if you wanted to.Great product I will be getting more sets for my other birds in the pics. The battery box is the bomb. The pic with the pen in it is showing the piece that puts pressure on the battery so no problem in getting the cg right. Here's some pics. Great product.... thanks sonat



Here is a video trying to get a blade strike. The cx3 is on the dx7 with 150% servo travel. The servo arm is using the 2nd hole.
