Another good thread all about the emax tinyhawk is this one:
Fair few of us have made modifications to ours to improve on things like range video quality in the goggles ect ect. @Steviegeek has even fitted his with a GPS module lol
But don’t run before you can walk. 
Oh but one thing I do recommend you guys do is secure your antennas as the mounting of both the video antenna and the spi receiver antenna out of the box is pretty poor and it won’t be long before they end up getting chopped by the props.
Video Antenna is best to just get a small zip tie and zip tie it to the frame to stop it flapping about.
The receiver antenna is a little more tricky, I used a small zip tie and some shrink tube. But I appreciate that you probably haven’t got shrink tube. So maybe just tape it to the zip tie.
Bit like this but yours will be smaller than that and instead of shrink tube just use some tape.
Just to keep the receiver antenna out of the way of the props.
