Range check; with trnasmitter (Tx) antenna down all the way, you should be able to get about 100 feet away and still have control of the plane's surfaces. (On the ground, not in the air!)
For the Cub you'll also need one, preferably two, flight battery packs, I'd suggest 7 cell, 300 mAH (Milli Amp Hour) NiMH's (Nickel Metal Hydrides). You can get them from Dave at Radical RC for about $15 each.
You'll need an ESC. The Cub only requires about 2 amp capacity, but I'd suggest getting something in the 15 - 25 amp range. That will give you coverage for the planes you're looking to build.
Dave also sells a "Pixie" 20 amp ESC for $38, which isn't too bad a price.
Dave's shipping is only $2.00!
The last thing you should need (?) is a battery charger for the flight packs. I'd suggest getting one that will do more than 8 cells in case you go bigger, but the cost can get high, so for now get an 8 cell charger. Maybe another $35 to $40. (Not sure what Radical has, but there are other suppliers for all of this stuff.)
