Linus, if you are reading this, please make these upgrades:
You need to properly rewire your Rhino Fire. You could do a kit like this:https://blastersmiths.co.uk/products/rhino-fire-wiring-kit
It will drastically increase performance (and reduce weight), if you use a lithium polymer battery like this:https://hobbyking.com/en_us/turnigy-bolt-850mah-3s-11-4v-65-130c-high-voltage-lipoly-pack-lihv.html
Also, I reccomend upgrading the pusher motor to this:http://www.blastertech.com.au/2S_Honey_Badger_Motor/p2928293_15736710.aspx
It, especially if you remove the front barrels, will get rate of fire equal to this (as it has the same pusher motor and battery type):https://www.youtube.com/watch?v=qAQpAx_d8so
