For the Rapid Stike: I found the Containment Crew site. Is the 12volt battery the highest? Is there a voltage you recommend ? BEX: is that motor you recommended from RHINO site
You could use either of the motors listed
on Containment Crew's website...both are made available by MakeTestBattle. If you use the Rhino motors to replace the flywheel motors, use no more than 11 or 12 Volts (3S LiPo). If you use the Honey Badger motors to replace the flywheel motors, use no more than ~7.4Volts (2S LiPo or 6S NiMH).
Bex is recommending something other than the Rhino motors, and I don't know much about them.
Keep in mind that you should never charge a LiPo inside of a blaster/while it's hooked up to anything. LiPos can be dangerous if used/charged improperly. However, the Rapidstrike has that nice big spot where the stock batteries go. It easily fits a LiPo and lets you access it easily for charging. Like Bex said, Hobbyking has good, cheap LiPos plus they sell chargers.
And just in case you want to go a less-DIY route Blastertech in Australia sells a pre-soldered motor upgrade
loom that also has a connector for LiPos. Or Tacticoolfoam sells a rewiring/switch kit
(includes everything the Loom has but the motors, but you have to put it together yourself). Of course, you could also get switches (rated 10Amps or higher) and wire (at least 18 if not 16gauge) yourself.
And yes for our purposes at least Trustfires and Ultrafires are pretty much equally not very well suited for nerf blasters, especially those with new/upgraded motors.
Nice work on the sword by the way!
