Well retard me didnt read the e-mail MHZ also sent me that said to use a 42mm or 45mm prop. So I am going with this setup with the 42mm prop. I will need a receiver and servo battery pack. I don't know how to choose that. Advice on that would be nice. Oh and I need to buy a switch also, right? OK well that takes care of all my money I am allowed to spend. That sure did go really fast.
