The Arrow looks like it should be a sweet flier. Don't build it too fast or you might be tempted to fly it before you are ready. Looking on Tower's web-site that might be hard to get used to from a trainer. Back when I got into the hobby, everyone was suggesting a shoulder-wing plane for a 2nd plane so I got the Sig Kavalier. It flies faster than a trainer, more responsive, but still forgiving. It is not as fast as a low wing though. I have noticed on here that some people are suggesting the Sig Something Extra as a 2nd so with some help the Arrow might make a good 2nd plane. If it wasn't for the expense. With the money you have tied up in that kit, you may want to hold out on that till a 3rd plane and slap a 4 stroke on it. Just my opinion
