Mav, get the Wind Dragon first... here's why:
Flying alone ain't half as much fun as flying (or teaching) somebody else. Once you get in the groove with the cheapie, keep it around for the wifie or kids, cousins, nephews, guy in the RV space next ta yah..
Now, it's time fer the 'good stuff'.. for radio gear Futaba rules the roost. JR, Hitec and Airtronics also make good systems.
For electrics with aerobatics as the target, 4 channel is a minimum.. and you'll want mixing fuctions. Cost for a FM 4 channel system with Micro Rx, & 3 micro servos.. about 150 bucks. 2 Servo systems.. about 125 bucks. Good stuff.
Next, most ARF setups come with a motor/gear train & prop.. most don't have packs or motor controllers. Motor controller type (brushless/brushed) depends on motor type and battery type (nicad/NiMH or Lipoly)... average motor controller costs about 45 bucks.
Next; Batteries. Unngh.. (my specialty) Nicad, NiMH are the least expensive, LiPoly the most expensive, particularly in terms of controllers, chargers and occasionally burning down somebodys house.. on the plus side they offer significantly more endurance and offer a power to weight advantage not enjoyed ny Nicad or NiMH.
Chargers are very very important.. basic models about 50 bucks, models able to deal with various diffrent pack sizes and technolgies can run about 100 bucks or more.
lastly.. motors. Wild varieties out there.. the numbers will make yah ga-ga. Most popular and competent are brushless 'axi' types; a 3-D motor and controller combo is about 100 bucks for the more popular foamies. Here's my favorite 3-D foamie:
E-Flite 3-D Ultimate Review The plane's only 50 bucks.. but to make it fly; figure on about a 400 dollar initial investment.. with the majority of that investment required to 'enjoy' the hobby from plane to plane.
Now, some of this gear can be aquired at under normal retail pricing.. buying used on RC Universe, RC Groups or Ebay such items as the basic radio gear (lotsa stanrd 4 and 5 channel systems for sale cheap.. folks move up to 6-10 channel systems all the time). Good deals on chargers can also be had in the used market place.
