OK, The retracts are the rs333RB and they exactly fit the original mounts. Now the strut length is 150mm for your order. The retracts have recently been greatly strengthened with a new 6mm rods and steel gears. Make sure the struts are for the new 6mm rods! There you go. I am holding in my hand the new version rs333rb and they feel SOLID! Now the new gear might be better with 155mm struts???? Be sure to ask!!! -Tom
You will not believe how good the plane will sound and fly with this 7-77.
