Hi, I have purchased a"Speed Star"520mm hull from HMZusa. I want to set it up with brushless motor. I have a fiegao 380-11s motor ,etti45a esc and a 47mm strut and 1/8"" flexi set up and 30 - 33mm props. Now the question is, as club rules ,our new class can only use 7.4v lipo batteries, so from you guys I want to know what MAH battery to use. Our race course is M shape and the duration of a race is 5 minutes.
I want plenty of feed back
cheers Wayn.

I would select the largest LiPo with the highest C rating that you can possibly fit. An ounce of weight here or there will not do any harm. Going 2P might allow you to split the packs up if this is allowed. To hit the 5min mark you will have to select the conservative prop that will allow 5min without anything heating up.
