I've got an old Kalt Enforcer that I'm resurrecting. It has an old futaba receiver, etc. I'm looking to replace this receiver with something modern. I also would prefer Spektrum as I'm new to the hobby and I've got a couple of planes with Spektrum receivers, so I'm at least a bit familiar with those.


I've read about "flight controllers" and "sats", but I'm not really up to speed on what is really required. I hope there is a "Safe" mode to help me not crash right away. I'm also curious about the number of channels needed. I have an NX8+ transmitter which should handle everything, but how many channels do I need in the receiver - I've heard 6 minimum, but would 8 be better? There are 5 servos in the Kalt plus one channel for flight mode. Is there anything else that needs a channel?


Thanks ion advance for any help.

Flight mode doesn't use a channel, it uses a switch. Gyro gain almost always uses a channel and most collective pitch helicopters (non scale) are 6 or 7 channels.

Flight controllers are used for flybarless helis, which yours isn't (to my best memory) it just needs a receiver with 6 channels.
