If you are actually flying 3 other planes from that Tx, then your problem is likely in your receiver, or receiver installation in that Cap 231. I normally get at about 50 paces with all of my Futaba equipment with the antenna fully collapsed. The very minimum that I will accept is 30 paces. Check your Rx antenna for breaks, keep it away from all other installed wiring, and even swap the Rx with a known good one, from one of the other 3 planes that you are flying successfully.
