Which kit? I have not noticed any Tomahawk kits. But, based on the full size, it might make a good second plane.
But, it really depends on your flying skills. If you can handle the trainer well in the sky and your landings are good, with the help of a good instructor you should do ok.
You will get a lot of responses as to what would be a good next plane. The 4* series is one. However, if you have an instructor teaching you, ask him. He knows your skills more and will tell you what to look for in your next plane. He might suggest one of the stick type planes.
Remember with your second plane you are still learning, so you do not want to spend a lot of money on a scale kit, only to fly it into the ground
