I call Horizon Hobby and told them about the problem about my other Extra Easy w/ MDS quiting on takeoff and that this other MDS was having the same problem on the ground and they sent me a new carb! I have only flown with this carb for about 30 - 40 minutes with out any dead sticks. Like I said it still needs to be broken in and leaned out! I can understand were you are coming from about the larger battery.
Thanks,
Brian
