well hello all i need some help from some experienced fliers...
i am a newbie i had my plane out yesterday to fly everything was going well but the tower .46 kept just shutting off... the experienced person who was teaching me how to fly said it was from the engine not being broke in after a couple of flights and the motor shutting off the instructor placed the glow starter on the engine and it flew fine until the glow starter died. the instructor said i needed a glow plug with a idle bar i am running the tower hobbies glow plug right now any ideas on what is causing this it happens any time any place usually about half throttle...... the motor just dies....

p.s. do you think i should try a OS #8 plug for this motor



thanks for any input
