When I first got into the hobby in '95, I got the tower trainer with their .40 engine they sold at the time. It was total junk. Never ran reliably or started reliably. Just a giant headache. The only good thing is that I got to be a pro at dead stick landings because of that engine.

I realize that was 15 years ago, but ever since then I've never felt comfortable spending my money on a Tower engine. Thunder tiger FTW!
