[:@]I just spent 45 min. in the shop programming for "spoilerons". The process worked great on a PA-18 Cub that I just completed. It has one of the Orange Rx that is compatible with Spektrum. With happy heart, I opened up the Extra and removed the "Y" cable from the ailerons, plugged the starboard into AILE and the port into what should be AUX1. This, however, is a Spektrum AR500 Rx and it doesn't have AUX1 it has another AILE. When the FLAP switch was thrown, the ailerons jumped to a full deflection in what would initiate a hard rolling move. Not good. The moral of this story is, get another Rx that has AUX1. I haven't maidened the PA-18 yet so I don't want the spoiler or flap. The PA-18 has barn door ailerons and one or your posts suggested not using Flaperons or spoilerons for these. Cubs really don't require flaps except for "bush" flying (STOL). Looks like I will be ordering from Hobby King again.
