Sehr guter Prop fr Leistungen bis ca. 400 Watt. Durchmesser exakt 193mm,

Die Stahl Splinte lassen sich von links nach rechts herausdrcken, Bltter umdrehen, Splinte zurckdrcken, und Prop als Pusher Prop einsetzen ! P-ein 260 Watt, 16800 1/sec, 1180 gr Schub. Sehr guter Wirkunsgrad, sehr empfehlenswert.Mine came with steel blade pins that were quite sturdy. For the arrester screw I drilled a 2.4mm hole all the way and cut a 3mm thread, so I could use 2 decent clamp screws in a balance way. Grub screws brake the plastic. My problem was drilling the shaft hole to size (3mm). With the plastic so soft it is HARD to drill straight enough for a properly centred hole. Lose precision and your prop is more like a vibrator! However, the price being so low you can use the blades on any other hub that has a 6mm shoulder and still save. The one I got working did not self destruct at 16000rpm, not sure about in the long run :) Good value for the money if it works for you.Seem to be "ok" quality however you cannot remove the propeller arms so cant fit as a pusher configuration, for a delta wing (x5 in my case) for example.
thrust is lower that on not folding prop?Hardly worth the money. Not very durable.Helice 7,5x4,5

Bonne qualiteTrs bon systme d'hlice rtractable.Better quality than I had expected. But, what a good price they are! I like it.A very good prop drains a littleCompletely useless..... Didnt even get to test flight stage. First turn of the motor and one blade broke away from the hinge. very poor quality and weak materials.
