Ummagawd Aerolite 2004 Motor – 1600KV/2400KV/3500KV

“With the advancements in digital HD FPV and regulations pushing our hobby to lighter and lighter weight restrictions, I decided it’s time to expand our knowledge and development into building a proper lightweight freestyle quad. While others are diving completely into the “build the lightest thing at all costs”, I wanted to take a more thought-out approach. With a target AUW of ~300g, I exhaustively searched, tested, tweaked, and finally found my ideal lightweight 5″ motor.”

The motor mount uses only 2 screws to secure, thus reducing any extra weight from the base. The bell is perforated with slotted cutouts to reduce rotational mass. This adds to the motor’s ability to rapidly change speed, similar to the effect of lighter props. Strong, yet lightweight titanium bolts are supplied to further reduce rotational mass to secure T-mount props. Because the prop shaft simply doesn’t need to be as long as other motors it has been reduced to 1.5mm. Now with the world’s first (on a 5-inch) “ribbon” motor wires!

The KV choices here come from testing 6s and 4s setups and lightweight 5″ props. This test was simple: “Pull out of a building and dive at the very last second… inches from the ground.” Whichever did this best, was the winning choice. I found that 1600kv on 6s was MORE than enough to accomplish this. So 1600kv it is… and with a 6s 450mah battery and HQ 5×3 bi-blades… you’ll find yourself getting 5-6min of blissful flights with enough power to put a huge smile on your face. The 2400kv is for the 4s folks with similar power to the 6s setup but with the emphasis shifted to the top end. If you’re looking for a motor for your 4-inch setup, the 2400kv also happens to be a perfect motor for a 6s heavy 4″ prop… if that’s your thing.
