Tower engines qre notoiously "iffy." They are either incredible or rotten. Those small trainers are really not the way to go. The Sig Cadet is the trainer of choice for many knowledgeable pilots. They are big enough to see really well, fly really well VERY slow as well as fast, and land like a ***** cat.

Please dont try and save a buck or two-- you will be disappointed if you do. Go with the Sig,either OS 46 or Magnum or Thunder tiger. DONT BUY A 4 channel radio. You will outgrow it quickly, and it has no resale value. I know this is not a cheap hobby, but give yourself the benefit of good stuff to geet a feeling for it. You can always sell your good stuff and not take too much of a beating. Good luck!
