Cost for the Firecracker isn't fixed yet but it will be around $150. This is for the base unit with an RC interface. 2x of these would replace a Scorpion XXL or Sidewinder functionally except for the mixing function of the dual controllers.
Running as an H-bridge the unit features short-circuit protection at 200A and overtemp protection at 100C for the MOSFETs. These protections are hard-wired into the H-bridge portion of the unit and don't depend on the CPU unit for their functioning.
An extruded Aluminum enclosure is available to house the unit and protect it from environmental and physical abuse.
The gallery below shows the prototype unit before the addition of the CPU board.
Firecracker showing the size comparison with the Scorpion XL. Note the screw terminals in the power attachement area.
Similar to those used on the IFI Victor and our Simple-H; they are rated for 30A but can actually handle more. With
the Firecracker these may be mounted or 12AWG wire may be mounted in the center hole. Note also multiple wires may be mounted
if needed for some application.
Firecracker showing the small surface mount MOSFETs. There are 12x of these for low resistance. Note the metal cans for the MOSFETs.
These provide excellent heat dissipation into the heatsink. Much better than the plastic case MOSFETs most other small controls use.
The Firecracker is designed to slide into this Extruded Aluminum enclsosure. It is from the same family as that used for our Sidewinder
dual control. These enclosures also have mounting rails available that slide into the dovetail slots on the sides.
Cooling of the Firecracker is through this heatsink. As you can see there is room inside the enclsoure for convective cooling.
A fan may be used to blow air across the heatsink for extra cooling. This will involve removing the end panels of the Firecracker or
machining some openings in the top of the enclsoure to mount the fan and provide vents for the air.
Thanks for looking at the Firecracker. We're testing this unit to see just how much it can do and we'll keep you posted when it becomes available.
