It's a great heli if you can get it going again. LOOOOOooooong out of production though, so parts will be hard to find.

Any 60 size tail blades will do. Plastic or Carbon ? It's up to your wallet.

You can use the cheapest servos you can find if you want.... But I'd recommend something with at least 5kg of pull or Digitals as a minimum.

Gyro = Futaba GY401. Sorted.

Engine. You need a heli specific motor (something with a H prefix) Can't help with the one you have I'm afraid.

You can download the manual from this site to help you : http://www.rchelibase.com/concept/

Do you have this heli? What engine have you used?

RE: Need help on possibility an Koyosho concept sr 60
 

No, I had a couple of Concept 30s a few years ago though. But I flew a friends 60 (just like yours) and fell in love with it. A real peach!

Any 60 size heli engine will do the trick. Zimmerman or Hatori muflers are my choice.

I'm flying a 60SR and by judging by the rotor head you also have an SR. I use the OS 70 heli engine in mine. One thing to keep in mind is that the clutch and fan collar are engine specific. You can save yourself some pain if you know what engine was in it before. If the clutch and fan will fit correctly on the OS 60 you have then they are for the OS 60 class engine so you could use the OS 60, 61 or 70 heli engines. I use the Futaba GY401 gyro. my servos are Futaba s5101 except for the tail rotor which is a Futaba s9254, the tail servo needs to be fast. For the muffler you can use almost any aircraft 60 size muffler but I suggest the OS Silencer or something similar. Tail blades are standard 95mm blades and the main blades are 660mm I use custom made 670mm. I can't imagine why your engine shaft is too short unless you have that large prop washer on there, if you do that needs to come off. The only thing between the clutch bearing and the engine block should be a small washer.

theres no prop washer. When you're fan is on the motor, do you add a nut inside? So my motor don't need prop washer?
