i'd get the futabla 2 pl 2.4ghtz, you don't need the 3rd ch, and the 2pl is a VERY nice radio i have the AM and LOVE IT, i may just have to get this one at somepoint
if you're looking at the tower for $80, the $20 is so worth it, id pay $120 or so for this remote, $100 is a steal, plus $50 in parts and you get $20 off your order from tower
