RE: 9cap question
I would recommend the 9c as it is a bit more capable and a little easier to program. However, if the 8u is a "super" (signified by a red S next to the model number) it is a good deal at $150 ($100 for the radio plus $50 for the frequency module). The Campac isn't necessary unless you have more than 8 models ready to fly. The choice is yours my friend...good luck!
p.s. If the 8u is not a super, forget it!
