Questo kit funziona perfettamente con HK-450 e allineare 450 elicotteri.Perché così a buon mercato?
Si tratta di un in-house prodotto progettato e si stanno ottenendo il prezzo di fabbrica diretto!
I eventually. Put it together but I had to use other bits from my heli spares.
Must be bits missing.
Apart from that the. Blade grip bearings have play in them !
Also small Allen bolts poor quality.
To be honest, save your money and buy a better one !!.
Sorry hk but come on this isn't what's described is tight tolerances.Super Umbaukit fr HK 450 Pro (Dmpfergummis fehlen) Fliegt mit dem Beast gleich um einiges ruhiger als mit den Paddeln. Kann ich sehr empfehlen.The quality of this head set looks good, there are missing rubber head dampers, but i fitted them from old HK head...Would be better to use new ones... It comes with long PRO version feathering shaft... Will use this with long blades 360mm and stretched tail boom tarot 480...Everyone says this is a great deal, but you really get what you pay for. I spent a couple hours trying to shim the head properly to eliminate the radial play within the grips without success. There is a appalling amount of play. I haven't test flown it yet. I'm guessing it will fly ok with a very mushy cyclic feel because of the head slop. Also, the screw heads seem to be made of Swiss cheese, so take care when applying torque to the screws, they strip easily. Better yet, replace them with better ones. The mixing arm bearings will seize if you tighten them too much, I just thread locked them and used minimal force to tighten. The kit comes with everything except the flap dampers. My advice is to try and find the stiffest flap dampers you can to try and eliminate that slop. Thicker the better. The machining and finish looks decent. However, the quality difference between the RJX head (which I own several of) and this head is apparent. Recommended for the casual helicopter flyer who crashes a lot. Otherwise, for the rest of us who prefer something of quality, avoid this. I'm not sure what I was expecting for the price. However, given the high praise by what I've read on the reviews, I did expect more.I buy this item and this kit is incomplete. The two rubber bushing is missing !!!!!! In the picture the rubber busingg is missing but this head can work without that rubber bushing.Purchased this head to try out a cheap flybarless option on a Thunder Tiger Mini Titan.
you have all the parts to swap out with the exception that the mini titan has 5mm blade root at the grips and this only has 4mm.
Easy enough to put together and slots straight onto the mini titan main shaft.
Used lock-tight in all the usual places however, upon spool up, one of the lock arm screws simply stripped the thread on the main assembly and threw itself clear.
Was very lucky I managed to put the heli down with very little damage.
Although it seems to be well built, I would not trust the head as it's clearly built on a budget as the price shows.
Time to put the heli back to flybarred I guess.Feathering shaft supplied is longer that the align 450 pro one. Binds up if you use the Align. Non standard "big" link balls. You get what you pay for! A poor quality copy of the RJX head.Good overall for the price but you can not use the supplied bearings as they are very sloppy. If HK increased the quality of it's bearings all their heli kits quality would dramatically increase.I found everything good apart from the main bearings (8x4x3) which are sloppy and will not let you get good blade tracking. Replace these with quality bearings you will be good to go.Excellent 450 size head, works well on trex 450 se v2 with a tarot zyx controller
