I built the 4* as a third build and it was a sinch. The hardest part for me was the covering due to the crazy scheem I went with. If you decide to got with it, best of luck! I found some great mods here on RCU and all helped. For the first time however, build it stock. It will help to avoid comlecations. Maby consider the landing gear mod (changing out the stock aluminum gear for Du-Bro nylon gear).
