“Simple and to the point...Purchased this Admiral 3300 pack back in June 2017 and the pack went bad in less than 6 months with very little use (maybe 3-4 flights). Contacted MotionRC, told them my problem and they went over the top and sent me a new replacement without any conflict. You can't ask for anything more then that! Conclusion: Battery: A bit disappointed but will see how new pack works out. MotionRC: Customer Service...Excellent!”
