I also just acquired a used but in good condition belt version of the N5c. I've been flying my E5 stretch to 606 for a few months and it's my best flying helis. I wanted to try nitro so I got the N5c.
I really like how my E5 flies, still trying to dial in my N5c. Hopefully I still can find parts for a little while.
I found this forum with lots of good info and the guys on here are great.
