RE: 1st and 2nd planes
Avoid trying war birds or scale models for even your second plane. The differences between them and actual trainers can be huge. They will a lot of times have higher wing loading and carry with them some if not most of the characteristics of their full scale counter parts. That in mind they can be far more challenging to fly and take off and land than you would think. You often have to keep power on for example while landing where as with a trainer they land easily even with the engine out. I have even heard from some that certain scale biplane models will almost be unflyable if your engine dies. Get a lot of experience with your trainers, get something with a symmetrical wing and then go into war birds and the other true scale planes. You will have a lot more fun with them. Jeff
