5V Regulator
Price: $17.99
Availability: Out of Stock
Item #: 5V-regulator -

This nifty little in-line voltage regulator will accept up to 11.1V input and regulate the output to 5V at 1.5A continuous. What's it good for? Use this to keep from frying a 5V servo when connected to a 2S LiPo or 8.4V BEC powered avionics system. Also handy for using other 5V electronics like gyros, gear door sequencers, and more.

Castle CC BEC PRO
Price: $44.99
Availability: In stock
Item #: CC010-0004-01 -

This is a stand-alone BEC. It's rated at 20A but read the fine print because the output depends on the input voltage and external temperature. We're not slamming a product we sell, just wanting to inform you before you pony up for it and then are disappointed. In theory this puppy is good for 20A. And it gives you two power connections to the receiver (like with our dual-connection battery packs, each is rated at 5A so in the real world, figure on getting 10A into the receiver). Honestly, it's...

Looking for a dedicated single-axis gyro to control the tail rotor of your flybar-equipped model helicopter? You've just found a nice one that won't break the bank! Set it up for either rate-mode or heading hold-mode and fly with more confidence. Think gyros are just for helicopters? Think again, because gyros can be pretty handy for fixed wing models too. For example, a Pitts Special can be a tough model for many because it's so short coupled it wants...

Programming this ESC is a matter of using conventional beep codes just like usual (e.g. based on the throttle stick position of your transmitter). However, if you're computer savvy and have access to an old Windows XP computer, then we have software that will let you download data based on time, like at 2 minutes, you can see what the current draw was, the pack voltage, motor RPM, and ESC temperature, as well as the throttle stick % at that instant. The point being you could go back and watch...
