Try the 11-5 first.

Futaba had a problem with bad swithches for the on/off on the plane. Many
planes were lost due to the power cutting off to the reciever. I lost a few planes
myself. I no longer use Futaba switches for that reason, I buy the aftermarket
switches from Cermark.

I fly Futaba radios, they are fine. You must have a crisp "snap/feel" to the
switches. If they are "soft" or do not have a crisp feel....don't use them.
