I obtained these Koko 2207 motors and a SKYSTARS F722HD flight stack two years in the past, however someway I forgot to assessment them. The motors have 16x16mm and may be put in on most 5-5.5″ FPV frames, no matter design and sort.
The Skystars Koko 2207 motors have 4 KV choices (1750KV, 1950KV, 2550KV, and 2750KV) and are appropriate for racing and freestyle FPV drones. The 1750KV and 1950KV are 4S suitable, and the 2550KV and 2750KV for 6S batteries.
The five-inch racing world appears to have largely settled on 2207 and 2306 as the best motor measurement. They produce sufficient energy for excellent acceleration and top-end velocity. The T-MOTOR F80 PRO motors put in on Pink Bull’s epic “Rocket FPV” drone achieved 217 MPH (349 KM/h) whereas chasing an F1 racing automotive.
SkyStars Koko 2207 1950Kv assessment
Disclosure: I obtained these 2207 FPV motors in a product assessment collaboration with SkyStars-RC. Though the motors had been supplied without cost, all opinions on this article stay mine, and the sponsor didn’t affect me in any way.
The motors are packed by pair in a cylindrical plastic case with included mounting screws and nylon lock nuts. The motor is principally black with a inexperienced mounting base. It has 120mm 20AWG wires with pre-tined ends. Every motor weighs about 35 grams, and it has a slight grip milled into the highest of the bell to forestall slipping the propeller. To be as gentle as potential, it adopts a hole motor shaft. To carry collectively the stator and the bell, it makes use of a screw, which is a pleasant contact over utilizing hard-to-remove C-clips.
As you’ll be able to guess from the product title, the standing has a diameter of 22mm and a peak of 7mm. The 1950KV model has a 52mΩ inner resistance and as much as 1605W energy (with 6s lipo and Gemfan 51433-3 propellers). You will have a 40-60A ESC to drive these motors.
There’s not a lot information concerning the supplies and building of the SkyStars Koko 2207 motor, so I’m not certain what sort of bearings or kind of magnets they’re utilizing. Anyway, the general construct high quality feels strong, and there aren’t any bizarre sounds after they spin by hand. I’ll come again and replace you once I’ve examined them extra.

2207 brushless motors for 5-inch FPV drones
Usually, 2207 motors produce extra torque than 2306 motors, which means extra management, which is essential for freestyling pilots. Apart from the Skystars Koko 2207 FPV motors, loads of different good choices exist. When selecting motors for 5-inch drones, you will need to resolve whether or not will probably be a 4S or 6S construct. 1900-2200KV is a center means and can be utilized with two battery choices.
iFlight’s Xing2 collection has top-quality motors which might be very sturdy and reasonably priced. Different choices are T-Motor F40 motors, FlyFishRC FLASH 2207, AOS Supernova, MEPS SZ2207, Amax 2207, and AxisFlying AF227.
