Everything John said. Plus at this stage you have to decide what type of power source you would like. Today we have so many options to choose from. I have one friend that started out with glow power then moved up to gas. Today he has gone 100% Electric, even in his giant scale warbirds. I have two old students that started out with glow then to gas and now they too have some really nice small electrics. Like myself they enjoy all three power sources. It's a lot of long term thinking but it's something you can decide as your learning. I teach with a glow powered trainer using a four stroke engine. I stress to the student that the four stroke glow and gas engines are my favorite but it's still up to them what they end up with. Most end up with all three at some point and some stick with just one type. As long as the fun factor is there it's just a choice thing. Just something to start looking at when your at the field and start giving some thought to.
