Hit and miss for me so far.

I've had a lot of problems getting my TMaxx tuned properly. Part of this could be due to the weather, part a touchy carb. I do like the electric starter though as it has saved my arm a whole lot of pulling.

You can expect the battery to give 12-15 minutes of constant turnover time before it needs to be re-charged. Generally though if you get the engine tuned properly that should last a long time since you will only have to turn the engine over for a second or two.

My RC10GT has been much more reliable holding it's carb settings and holding a continuous idle. Generally once I get it started it stays running until either I stop it or it runs out of gas. The TMaxx has been much more sensitive and doesn't like to hold an idle all that well.
