Well Ryan,
unfortunately I don’t know about your particular build but for my 808 here is what I have and what I work with.. (Hope this helps?)
I have a total of 44mm from the top of my chassis to the bottom of the body. I use a PQ 4s 5000mAH 25C and it's good for 20+minutes and the dimensions are 166 x 48.5 x 35.5 mm, when I add the RCM battery try and the Strap thickness (cant forget the details) I end up with 42-43mm total height / IE NO SHIMMING!!
Hope that helps (???) best of luck and for what it’s worth I did order up a 4s Zippy last week, I don’t expect it to be 30-35 C (lets get real) but for under $100 what the hell it got to be worth it..
Please let us know what your thoughts are on what you decide to go with..
Have a great one Ryan..
Shaun.
