HGLRC Specter 1804-3500KV 4S Brushless Motor for 3-3.5Inch FPV Freestyle Racing Drones

These motors are great. They throw around my 350g 3.5 inch quad like nothing. Super fast and responsive. Can’t beat them for the price.

wow ! Beautifully designed and manufactured. You know you see a picture with the coils so perfectly wound, and think Yeah Right, But it's true. I only hope they maintain such a fair and competitive price. And 2 day delivery on amazon.

These motors are legit!!! I put the 1804 3500kv motors on an AvionRC Nexa 3.5" Evo Pro running 4s lipos, jhemcu f745 AIO and dji o4 pro and it has the speed and thrust of a 5" running 6s batteries combined with the nimble, lightweight agility of a sub 250(ish) 3.5". I was able to reach 113mph with these motors on the 3.5 freestyle quad using GemFan 3630 props and a gnb 880mah 160c 4s LiHv battery. The build quality of these are very good as well. The stator wires are neatly wound and the magnets are very strong making for that notchy feel when turning the motor by hand.

I used these motors on a lightweight long range 5inch kwad build. Probably a little undersized for the use but I get 15 minutes on a 1300mah 4s Lipo and almost 25mins with a lion 4s pack made from salvaged tool batteries. They survived a crash just fine when I crashed into a tree and then the 30ft fall afterwards.

Awesome motors, have them on a 280 gram 3.5” and the run nice and cool with excellent performance (haven’t crashed them yet though). Will buy again

Extremely smooth flights with these. I will definitely be ordering another set of 4. I have them on a flyfish 3.5 with a 55amp esc. Little overkill but paired with these motors, excellent.

These are great for a 4inch build. Awesome on 4s and plenty of power.

Ordered these for my first full build a 4s 3.5” 285g AUW. These motors rip, had to apply a small throttle limit as my hover point was down around 15%. Running at throttle cap of 90% with small amount of expo which brought hover point to about 25-30%. Motors stay cool even when really pushing them. They have handled crashes well with 0 damage. Great motor for the price!
