Nice tutorial.It is however necessary to point out, that LiPo 3s and 8xAA NiMh have different minimum and maximum voltage. If you do not do any action likely to destroy LiPo battery due to excessive discharge.If the RC transmitter allows you to adjust the voltage range of the battery pack, it must be properly set. In some cases, the measuring of the battery voltage does not work properly (it is then necessary to connect the suitable voltage divider to measuring cables).Another option is to use a suitable device to monitor voltage. For me, work well in this situation a voltage monitor from HobbyKing (see article http://ds212.trojankovi.cz:5002/blog/#param=id_34... - sorry, it's in Czech, but there are pictures ...). This device today has not sold , now sells similar:http://www.hobbyking.com/hobbyking/store/__63697__HobbyKing_8482_Lipoly_Low_Voltage_Alarm_3s_8s_EU_Warehouse_.html.

I made it! I attached an image of mine. I have the air compressor, but it doesn't work so I will probably need to return it and get a new one. But right now, it works great using a bicycle pump.I followed the instructions relatively word-for-word, but I added a few things:- I have two 9-volt batteries in series to give the valve more power- I attached a laser pointer so I could have laser sighting. At close range, it's pretty accurate!- I have a long barrel and a short barrel attachment. The long is 16 inches (pictured), and the short is 8 inches.- I added a rocker switch between the trigger and the battery, to act as a safety switch so there are no misfires. - And lastly, I wrapped electrical tape around the handle to add grip as well as look (but mostly to cover up my sloppy paint job).Overall, the build went very smoothly (except for the painting, but I gained a lot of experience with spray-painting for the future).Thanks so much for the Instructable, it was really helpful!
Awesome! I have most of my parts, I can't wait to start building! Thanks for the awesome Instructable.
You need an inline 1" sprinkler valve. They are usually light green or black colored.
