it first depends on size of SD card and type of camera , full video or pictues Ect Ect Im sure you know these things

what shot you want to get ,for me I may try to get an air to air shot of my kids mustangs
I might make a box to put my camera in for a full video ,other club members have a servo to turn there camera on and off

on a side note I did strap a go pro camera on my Slow fly Cub video came out poor with alot of noise and the camera cut off after first turn [:@]

our club had our field fix up day for this year was great to get to the club again ,may take me a couple of more weeks to get things ready cant wait !!
