Newbees! You just don't understand. The second airplane is not that difficult. It's determining when the wife will let you get the 11th or 12th one that is hard
Seriously though. After your highwing trainer don't just jump into a full competision pattern ship with about $1200 - $4000 in it. Get a Sig 4 Star (Great aerobatic trainer with pattern charactoristics) and go with it. The 4 Star is available in a 40/60/120 size. Get the one that will best suit your 3rd plane. While I typed these as instructions or directives they are meerly a sudjestion
