Default Do I need a 6 or 7 channel receiver?

I have an electric FW190 I'm trying to complete with the following controls. Throttle, single elevator,and rudder. Dual aileron, and flap servo's. It also has Electric retracts.

I'm assuming some type of Y on the flaps, or reversing the head of the servo. I don't want a Y on the ailerons.

RX CHANNELS:
MOTOR-ESC=1
RUDDER=1
ELEVATOR=1
AILERONS=2 IF NO Y WANTED
FLAPS=1 UNLESS YOU WANT 2 FOR EASIER ADJUSTMENT IN SETUP
RETRACTS=1

So you need at least 7

Have fun.

Generally speaking, with any aircraft, channel mixing is preferred over using a Y Harness. If you do not have enough channels for channel mixing, a JR Matchbox or Futaba Servo Sync is much better than a Y Harness, but in a foamy, that is not always practical.

Dual Flaps or Dual Elevators almost always require reversing one servo. A reversing Y Harness is worse than a Y Harness. They constantly need adjusting, and some radios recommend not using reversing Y's.

If you have to use a Y Harness because you do not have enough channels, use it on the Ailerons so you do not need a reversing Y. You can then connect each Flap servo to a separate channel and mix. Avoid Y Harnesses if you can, all together.

Give us the whole story.

Which radio do you have? That will provide better information of the potential mixes available to you instead of guessing. As said before, mixing is better than using a Y harness. So going by that statement:

Throttle 1
single elevator 1
rudder 1
Dual aileron 2
flaps 2
Electric retracts 1 or more

I would suggest an 8 channel receiver or better, depending on how you connect the retracts.
