The RCM Trainer is a good plane and the Magnum engine is a fine runner. I am currently training someone with this combo. This plane requires less build time the most others and could be had for $140 with the motor directly from Global. The LT 40 and Telemaster 40 have larger wings (73" vs. 61" or 62") which creates a more stable plane. My LT 40 has an ASP .61 on the front for banner towing and messing around.
