Nitro is much cheaper to get into up front and you can start out with larger planes than what you can with electrics.

In turn larger planes are both easier to control and see, and retain your interest much longer. They are better trainers, handle better in wind, and are easier to repair and maintain as you learn.

There's a reason that Nitro planes are preferred as trainers for organized training sessions.

At most clubs you need to have at least a .40 size plane, to bring to training.... so that it is adecuate for buddy boxing, etc.
