Armattan Mongoose 5 Inch Quadcopter Frame
What is it?
The Mongoose is the newest entry into Armattan’s Lite series of frames, and is built to be inexpensive, strong, and light. While those descriptors often can’t coexist, the Mongoose provides a unique package that truly encompasses them all. At 61 grams and less than $40, it is less than half of the weight and price of the fabled Armattan Chameleon. Even so, the high quality carbon fiber, aluminum, and stainless steel hardware provides a robust airframe that you’ll have to work to break.
One of the unique weight-saving features of this frame is the front standoff. By utilizing a piece of 3D CNC’d aluminum, it combines the forward structure of the frame with the FPV camera mount. This will fit and protect any of the newer 19mm micro FPV cameras produced by the big manufacturers. Another feature of that standoff is that it continues down to help secure the arm. By doing this on each of the corners, the total number of bolts needed to assemble this stretched-x racer was reduced to 12.
Set and sunk between the 3mm arms is the stack provision for this frame. Either 30.5mm or 20mm flight controllers will be right at home, and either will easily able to accommodate multiple boards with the provided 23mm of headroom. Also, since the stack is set between the arms, swapping an arm will be a piece of cake. Remove 2 screws to take out the old, and put them back to install the new: no need to fiddle with the stack. And by the way, since the arms are a bit thinner at 3mm, motor bolts are provided so you can avoid running the risk of shorting your motor windings to your frame and releasing the magic smoke.
As you likely know, the debate between batteries mounted on top or bottom rages on. That’s why this frame can support batteries in either location. It’ll even come with 2 custom LiPo protection pads to help keep your battery where it belongs. Lastly, the zip tie holes in the top plate provide a clean, solid mount for your VTX antenna. There’s much less cause to worry about snapping your SMA adapter when it isn’t exposed to the dangers of a direct impact.
