Unit Weight (g):
These seem to be really good propellers. They balance good and look nice. The only problem is I went through three of them on three consecutive flights. One after another they broke. All wood blades can break but these shattered to pieces on pretty good landings. The prop may have only slightly touched the ground. Two flights the engine was still running after they broke in half on two of the sides. Very poor strength. Make sure you have at least two or three inches of distance to the ground under them - when the plane is level!
Outstanding performance. In my DLE 55 turns 7100 RPM and 29 lbs thrust. Pulls my A.W Edge 40 with 18 lbs and A.W. Yak 54 with 18.5 lbs with autority.I bought one for my DLE-55. The weight is only 113 gr - Perfect.
The balance is middle good - usually quality for serial production prop. The end finish is not good - there a areas with not enough polish - seems the varnish/lacquer absent. Recommend to make a finish sanding with 200 to 500 and using laminate epoxy as varnish.
The wood is beech and wasn't good positioned when they prepared the CNC milling - wrong wood treads by prop pitch. The producer should remark the difference between 2 blades before start the mill and don't produce the prop.
Let wee see what work will be done after a week.This is great propeller, but this is a real 23x8.ideal pra mi 56cc dlaexcelente para un 50ccGood quality, very reasonable price. Barley had to sand the propeller for a perfect balance. seems to be good wood used.Uso em meu FTL 52 cc
