Seems to be a copy and paste of what Towerhobbies.com carries.
Before any other members discuss this I would like you to go to your hobby shop and talk to them about what they carry and what they feel is a good starter Nitro RC. Really, there is no "easy" starter Nitro. There are the slower and easier to tune nitro engines but there is no "easy" Nitro. Each one carries a special way to be tuned, ran and taken care of; there is no "set" rule for each and every Nitro out there.
Since you'll probably be purchasing it from them it will be a lot easier for them to help you because it's one of their carried products. This means they probably have experience with the motor, the parts and the warrenty incase something goes wrong during your Nitro experience.
Talk to your Local Hobby Shop first. Remember, this is an Xmods forum, not a Nitro forum. Not many members have knowledge about Nitro RC.
