This retract is on my 4.5kg corsair and is OK. I bought 4 pairs, because of mishandling and crash/hard landing. In my experience, the two mains trouble are the grub screw and the electronics. The grub screw doesn't hold the axle very tight such that the wheel tend to turn left or right. The electronics tends to stuck the retract down (luckily for now), so I had to replace two single retract ; I have now notice that shaking firmly the retract helps to unlock the mechanism such that the retract gets up. I am wondering whether the twice more expensive 15kg rotating retract would have saving money : I am not that sure they would have survived some of my mishandling. It is still unclear to me.L'usinage des pices semble pas mal au premier abord, mais a un peu de jeux lorsque le train est dploy.
Sinon les cartes lectronique sont trs fragile. J'en ai grill deux en moins d'une dizaine utilisation. Surtout, avant de les utiliser, renforcer les interrupteurs des cartes lectronique, comme expliqu dans les fichiers tlcharger. Et aussi ajuster bien les passages de jambe de train de faon ce qu'il n'y ait aucun effort lors de l'ouverture et fermeture du train, car au moindre effort, la carte grille ou les interrupteurs sautent.
I hoped the reviews regarding these was wrong but im sorry to say I purchased a pair and once again only one works, the other rotated 2 times then clapped out, really sad to see such rubbish being sold and no body doing anything to remedy the problems, HK you need to remove these from sale until the supplier gets the product right.I just received these retracts and so far have had none of the problems mentioned above, the quality for this price is amazing compared to the overprised e-flite units, check out the video section for a short video that I have just uploaded!
