Yes... the exact same thing happens with me. I only replaced the tail gear from the set "50H08-26 Gear Set" because replacing it passed the gear test as mentioned in the orig post. I'm wondering if I need to replace the larger gear in the set that goes towards the main gear. This is a chronic problem with the G2 and I'm hoping someone comes up with permanent fix. Does anyone have a step by step instructions and troubleshooting tips for a newbie?

PLEASE!
