Ok, new question, Is the main shaft and main gear for the HBCP 2 truer than the stock BCP main gear? Even with a new stock E-flite main gear there is a wobble in the gear part that takes the gear close to the motor then further from the motor which not only binds the motor but also causes a wobble. The shaft is straight but the gear mounting sucks. If the HBCP 2 is better I want it are these the right part numbers? Main Axis (shaft) EK1-0266 and Main Gear Set EK1-0238
