any upgrades needed?

Im about to order one of these helis and was wondering if there any helis that are NEEDED. How does it fly out of the box for those of you already flying this heli?

You will like the way it flys right out of the box. I have two Raptor 50's, and a 90. They have not seen much fuel since i got the Frenzy. I did add a metal swash, and a Mavrikk Raptor tail only because i like those items.

Although it is not really needed I replaced the tail drive pully with the raptor aluminum one from Heliproz. See this thread https://www.helifreak.com/showthread.php?t=132324

This is because some of the ones in the previous batch of kits were out of round. My tail has no vibration after installing the raptor pully. It was a pain getting the old pully off without special tools. I ended up using a drill press with an appropriately sized drill bit to push the pin out of the drive shaft.

Also you may want to put the thrust washer from your engine on before puting the fan assembly onto the engine. The drawings do not show the thrust washer. It won't effect anything much if you don't install it but the clutch should end up being flush with the bottom of the clutch bell if you do install it.

The best bet is to not use the washer under the fan. There is still plenty of clutch contact area and some people have found out, the hard way, that with the washer under the fan it's too high and rubs the fan shroud.

It's works both ways. But in my case there was a gap that would have easily been closed via a thrust washer. I didn't put mine in either but I did adjust the hole size of the lower bearing block holes in the frames so it lined up perfectly.
