hi ifly a cap 580 1/3 scale . there is nothing hard about it it is just bigger with a different propulsion {hoarse power). Just go by the book and you won't go wrong. bigger is better they handle the wind better and my gosh you can see it real good. I don't know if you guys have to be certified to fly large models 7kg and above but here in aussie we do.but it is not hard. the set up on them is not hard either i run a power box in mine . 2... 5 cell sub "c" 3700 nmih for the rx and p/box and 4 cell sub"c" 3700nimh for my ignition on my DA100
