The SZ2207 would be the second FPV motor from MEPS reviewed right here on FirstQuadcopter. Each motors are supposed for 5-6″ racing drones. Whereas the SZ2306’s stator has 23mm width and 6mm top, the SZ2207’s stator is 22 mm/7 mm. The 2207 has a narrower stator width, so you may anticipate lighter rotational inertia that permits for sooner RPM modifications, giving freestyle pilots superior responsiveness.
The Area SZ 2207 motors from MEPS have three KV choices specifically designed for 4S and 6S LiPo batteries and 5″ propellers. Based on the KV model, these motors can generate energy from 846.7W to 1148.4W. Relating to racing drones, you need to think about a thrust-to-weight ratio of 10:1 and even 14:1. The corporate has two 3-blade prop choices for these motors: SZ5145 (4.5-inch pitch) and SZ4942 (4.2-inch pitch).
MEPS Area SZ2207 evaluation
Disclosure: I obtained these FPV motors for a product evaluation collaboration with MEPS. Though the merchandise had been supplied without cost, all opinions on this article stay my very own, and the sponsor didn’t affect me.
In Could 2023, when MEPS contacted me for the primary time to evaluation the SZ2306 motors, their product vary solely included two motors, an FC and an ESC. Now, 9 months later, they’ve a wider market providing. Throughout this era, an aggressive advertising and marketing marketing campaign supplied free samples to many reviewers, together with me. Many think about this technique too pushy, however so long as they don’t attempt to affect the evaluation’s final result, it’s the appropriate strategy for a brand new model that desires to goal excessive.
Along with the SZ2207 motors, MEPS included 4 units of their propellers, SZ5145. I opted for inexperienced for each motors and propellers.
MEPS SZ2207: At a look
The Meps SZ 2207 motors are supposed for 5-6 inch FPV racing drones. There are three-speed variations: 1750KV (6S), 1950KV (4S/6S), and 2450KV (4S). You’ll be able to select from 4 stunning colour choices: Fluorescent inexperienced, Titanium gray, Cyan, and Orange. Every motor comes with 5mm propeller lock nuts, a spare shaft screw, and a set of mounting screws (4xM3*7mm and 4xM3*10).
A tiny high quality verify (QC Go) card is supplied with every motor. I don’t know in the event that they check every motor individually or whether it is only a advertising and marketing trick.
The motors weigh about 34 grams and have 160mm lengthy wires (20AWG). The white motor leads are pre-tinned for straightforward soldering. A slight grip is milled into the highest of the bell to stop slipping the propeller.
As you may guess from the product title, the standing has a diameter of 22mm and a top of 7mm. The 1950KV model has a 66mΩ inside resistance and as much as 1148.4W energy. The unibell rotor is comprised of 6082 aluminum, and the shaft is comprised of TC4-reinforced titanium alloy. To be as mild as potential, it makes use of a hole shaft, which has grow to be a market normal these days. The bell is generally open for higher cooling, therefore elevated effectivity.
The N52H arc curved magnets present environment friendly and secure energy whereas response time for maneuverability is minimal. The winding makes use of military-grade high-temperature enameled wires that promise to last as long as 220°C.
The bottom has a 19x19mm mounting sample with M3 screws. The MEPS SZ2207 motors are appropriate for long-range, racing, and freestyle FPV drones. I like to recommend the 1950KV model with a 4S LIION battery for LR and the 1750KV with 6S LIPO for racing.
The general construct high quality of the MEPS Area SZ2207 seems to be spectacular for the low value. The bearings run easily when rotated by hand.

Pricing, availability, and bundles
The Area SZ2207 motors with three KV choices may be bought immediately from MEPS’s on-line retailer. Throughout their Holyday Flash Sale, you may get one motor for simply $11.94 (40% off from common value). For a bundle set of motors with propellers, you will want to pay $61.95. Along with your combo buy, you’ll obtain two battery straps and a hat without cost. The five-motor package (4 + one spare) prices $66.45.
MEPS SZ2207: Finest options in your cash
In case you are constructing a 5″ FPV drone, MEPS isn’t the one model you need to take a look at if you select the motors. For instance, T-motor (which many imagine is the model behind the origin of MEPS) has some nice choices, such because the V2207 V2.0, P2207 V2.0, and F60PROV 2207.5. From iFlight, the XING2 2207 can also be an incredible different.
After evaluating many comparable measurement motors, Chris Rosse concluded that these SZ2007 are the “MOST EFFICIENT“.
If weight is essential, you too can think about 2306 motors, as they’re a couple of grams lighter and supply about the identical efficiency.
In comparison with different manufacturers, MEPS motors are 10-25% cheaper than different manufacturers, so in case you are on a good price range, it’s in all probability the best choice.
