Hi i am new as well and got my second plane bout 2-3 months back .It was after my trainer as well. The first thing everyone advises is not to get a scale model for a second plane.A sport low wing or mid wing would be the best.Scale planes have different characteristics and a new timer would not be too familiar with their stall rates etc.....
BUT THAT IS UNLESS YOU ARE 98% sure(well no one is 100% sure of anything!!) of wanting to get that 'particular dream plane' you have been itching to get your hands on.I staraight went for a CAP 232 size 40 by Kyosho.Well you see i had never flown a low wing or even a dragger for a matter of fact ever before!! Other flyers thought it was going to be a 'KAMIKAZE' on the first flight.Well i didint do the maiden flight and gave it to a senior flyer. Then i took over and to my surprise it wasnt too bad. Well it always needed speed and thats about it.The only prob was landing.I could never get to do a perfect landing for a few flights.A few times the landing gear made of aluminium i think had gone 'flat' 180'degrees because of hard landings.Well i can fly it well now Touch Wood and it is true that everything needs experience.So always ask for help to your seniors because for sure(this is 100%!!) they would know something more than you.
So go get the plane you have always had your eyes on if you are sure you can handle it or if you are not too sure then go get a sports plane or even something like U CAN DO 3D or FLIP 3D. These type of planes are quit easy to fly and can be flown at very low speeds.Take care man and make the best choice.
