Hey Squee. Thats not just a TM problem. They are having the same problem with the TZ and I have a OS 12CV-X (little red head engine)and it has the same problem
here it is discussed at length and they have a solution to the problem. I would suggest you read up on before you get the engine of your choice. I'm not telling you to not get the engine, i'm just suggesting you need to read and get this product when you do.You need to read the first two to four pages to understand what is going on
Work because i gotta, play because i wanna
People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise
