I spent an interesting Easter break with my Hail-Fire, a pair of RM2 motors, couple of 14500 batteries, and a screw driver. Yep, it was a big ol' party boys. And as most big parties go, there was a little bit of drama.

I got everything apart, replaced the motors, soldered everything together, and screwed the shell back together, only to find that my Hail-Fire could only shoot 2 darts before quitting. Turns out there's a hidden thermistor (aka fuse) hidden in the body of the Hail-Fire. If you send me $85 in unmarked five dollar bills, I will tell you where that thermistor is located. (yo moderators, that was like a joke, ok, don't freak out. I'm not trying to give away darts or anything, jeez)

After removing the thermistor, and reassembling the shell, I discovered that my Hail-Fire could shoot a whopping 8 darts in a row before quitting. DOH !!! True, yes, it was a 100% improvement, but I was kinda hoping I could shoot maybe a 100 darts in a row ... or more.

Turns out the flywheels were slightly imbalanced. At vastly increased speeds due to the RM2s, they were causing a harmonic vibration that caused the motors to stall. So I strategically placed small amounts of electrical tape on the insides of the flywheels to balance them at really high speeds. Remember watching the guys balance your car wheels at the tire store ? Yep, same idea.

Got it working perfectly now. Bringin' the rain my friends. Rain of foam !
