hey shaun ive been playing paintball for about 5 years now and it is crazy to see this thing inside of an RC car!
my 2 favorite hobbies being combined into one!!
couple things i want to mention.
1. C02 is not the best for that type of gun especially if you plan on using full auto. it should not ruin anything but you may blow hoses due to the freezing c02.
2. the hopper you got may not be able to keep up with the gun so make sure you keep the eyes on your gun ON or it may start to chop balls in the barrel. which will result in you having no aim and may hit things that you did not intend on hitting
3. this is one AWSOME project!! if you have any troubles with the paintball gun hit me up. i should be able to help you out!
good luck man!
