It sits between our mid-range 43mm stator lineup and the full-size agricultural 5315 \u2014 we wind this 52mm stator for 420KV, test it hard on two propellers, and build it for operators who want heavy-lift capability without paying for a 12S power system.<\/p>\r\n\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">Most agricultural motor reviews give you one propeller and call it done. That is not how spraying operations actually work \u2014 you might run 15-inch props on a hexacopter for lift, then switch to 13-inch on a quad for a tighter spray pattern. So we tested the <strong style=\"color:#ffffff;font-weight:600;\">5215-420KV<\/strong> on both HQ 15\u00d77\u00d73 and HQ 13\u00d79\u00d73 propellers using the same 8S voltage, same test stand, and same ambient conditions. In short, here is what the throttle sweep data says about where this motor belongs and where it does not.<\/p>\r\n\r\n<h2 id=\"specifications\" style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#ffffff;font-size:22px;font-weight:700;border-left:4px solid #6dc0e3;padding-left:14px;margin-top:40px;\">5215-420KV Specifications at a Glance<\/h2>\r\n\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">Before we dive into test data, here is what this motor looks like on paper:<\/p>\r\n\r\n<table style=\"border-collapse:collapse;width:100%;margin:24px 0;border-radius:8px;overflow:hidden;\">\r\n  <thead>\r\n    <tr>\r\n      <th style=\"color:#6dc0e3;font-size:13px;font-weight:600;text-transform:uppercase;text-align:left;padding:12px 14px;border-bottom:2px solid #6dc0e3;background:rgba(109,192,227,0.06);\">Parameter<\/th>\r\n      <th style=\"color:#6dc0e3;font-size:13px;font-weight:600;text-transform:uppercase;text-align:left;padding:12px 14px;border-bottom:2px solid #6dc0e3;background:rgba(109,192,227,0.06);\">Value<\/th>\r\n    <\/tr>\r\n  <\/thead>\r\n  <tbody>\r\n    <tr>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">Motor Model<\/td>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\"><strong style=\"color:#ffffff;font-weight:600;\">5215-420KV<\/strong><\/td>\r\n    <\/tr>\r\n    <tr>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">\u0420\u0430\u0437\u043c\u0435\u0440 \u0441\u0442\u0430\u0442\u043e\u0440\u0430<\/td>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">52 \u00d7 15 mm<\/td>\r\n    <\/tr>\r\n    <tr>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">\u0420\u0435\u0439\u0442\u0438\u043d\u0433 KV<\/td>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">420 KV<\/td>\r\n    <\/tr>\r\n    <tr>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">\u041d\u043e\u043c\u0438\u043d\u0430\u043b\u044c\u043d\u043e\u0435 \u043d\u0430\u043f\u0440\u044f\u0436\u0435\u043d\u0438\u0435<\/td>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">8S (29.6 V nominal)<\/td>\r\n    <\/tr>\r\n    <tr>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">Peak Thrust<\/td>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\"><strong style=\"color:#ffffff;font-weight:600;\">5,544 g<\/strong> (15\u00d77\u00d73 @ 75% throttle)<\/td>\r\n    <\/tr>\r\n    <tr>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">Peak Power<\/td>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">1,213 W<\/td>\r\n    <\/tr>\r\n    <tr>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">Recommended Propeller<\/td>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">13\u00d75\" \u2013 15\u00d77\"<\/td>\r\n    <\/tr>\r\n    <tr>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">Magnet Spec<\/td>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">N52H (120\u00b0C Curie)<\/td>\r\n    <\/tr>\r\n    <tr>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">Winding Rating<\/td>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">220 \u00b0C<\/td>\r\n    <\/tr>\r\n    <tr>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">Bearings<\/td>\r\n      <td style=\"color:#d0d6e0;font-size:14px;padding:10px 14px;border-bottom:1px solid #2a3a5c;\">NSK 696ZZ (Japan)<\/td>\r\n    <\/tr>\r\n  <\/tbody>\r\n<\/table>\r\n\r\n<h2 id=\"test-data-15\" style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#ffffff;font-size:22px;font-weight:700;border-left:4px solid #6dc0e3;padding-left:14px;margin-top:40px;\">Real-World Test Data: 15\u00d77\u00d73 Propeller on 8S<\/h2>\r\n\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">The 15-inch prop is what most agricultural hexacopters fly in the field.

Specifically, six of these give you roughly 16.2 kg of total lift at 2,421W. That is enough to carry a 10L spray tank, pump, and battery on a typical 6\u20138 kg airframe with a comfortable 2:1 thrust-to-weight ratio. Efficiency at this operating point: <strong style=\"color:#ffffff;font-weight:600;\">6.7 g\/W<\/strong>. Moreover, the curve stays respectably flat through the mid-range \u2014 6.7 at 50%, 5.7 at 60%, still 4.6 at 65%. So the torque curve stays clean across the range you actually fly.<\/p>\r\n\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">At 75% throttle, peak thrust hits <strong style=\"color:#ffffff;font-weight:600;\">5,544g per motor<\/strong>. On a hexacopter, that is over 33 kg of total thrust \u2014 enough to punch through a gust front or pull out of a downdraft with a full tank. In addition, the 1,213W power draw at this point sits well within what a budget 60A 8S ESC handles comfortably.<\/p>\r\n\r\n<h2 id=\"prop-comparison\" style=\"font-family:Segoe UI, Inter, system-ui,

However, the 13-inch pulls only 34.47A at 75% throttle versus the 15-inch's 38.33A \u2014 about 4 amps less per motor. Consequently, on a hexacopter, that is nearly 24 fewer total amps at full punch.<\/p>\r\n\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">If your frame has tight prop clearance or you are running on a quad where raw thrust per motor matters less than current headroom, then the 13\u00d79\u00d73 is the right prop. On the other hand, if you are on a hexacopter with room for 15-inch blades, the efficiency advantage of the bigger prop becomes clear \u2014 6.7 g\/W vs 6.0 g\/W at hover adds up to several extra minutes of flight time over a full spraying session.<\/p>\r\n\r\n<h2 id=\"build-quality\" style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#ffffff;font-size:22px;font-weight:700;border-left:4px solid #6dc0e3;padding-left:14px;margin-top:40px;\">Build Quality: What Makes an Agricultural Motor Last<\/h2>\r\n\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">Agricultural drones do not get to fly in clean air. They operate in pesticide mist, fertilizer dust, and 40\u00b0C ambient heat for hundreds of hours each season, so the 5215 is built with that reality in mind.<\/p>\r\n\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">The stator uses <strong style=\"color:#ffffff;font-weight:600;\">220\u00b0C-rated winding wire<\/strong> \u2014 the same spec as our 5315 heavy agricultural motor. Standard 180\u00b0C windings start degrading after 150\u2013200 hours of sustained high-ambient operation, but the 220\u00b0C windings in the 5215 stay within spec well past hour 300. Similarly, <strong style=\"color:#ffffff;font-weight:600;\">NSK 696ZZ bearings<\/strong> come standard on every unit.

The 5215 runs on 8S, which means cheaper ESCs since 60A 8S units cost about 40% less than comparable 80A 12S units, plus lighter wiring harnesses and smaller batteries for equivalent watt-hours. For instance, if you are building a 10\u201315L sprayer then the 5315 is overkill \u2014 you would be paying for thrust you will never use while carrying extra ESC weight you do not need.<\/p>\r\n\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">One operator in South America ran 5215s on a fleet of 40 hexacopter sprayers before upgrading to 5315s on 12S for a larger tank size. Their feedback was clear: the 5215s handled 12L tanks reliably for two full seasons without issues. In fact, the move to 5315 came only because they switched to 20L tanks \u2014 not because any 5215 had failed. So here is a simple framework: if you are running 10\u201315L tanks on 8S, then the 5215 is your motor. If you need 20L+ capacity on 12S, step up to the <a href=\"https:\/\/pithrust.com\/ru\/5315-420kv-motor-review\/\" style=\"color:#d0d6e0;font-weight:500;text-decoration:none;\">5315<\/a>.<\/p>\r\n\r\n<h2 id=\"applications\" style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#ffffff;font-size:22px;font-weight:700;border-left:4px solid #6dc0e3;padding-left:14px;margin-top:40px;\">Ideal Applications<\/h2>\r\n\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">Now let us look at where the 5215-420KV actually belongs \u2014 and where it clearly does not.<\/p>\r\n\r\n<h3 style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#ffffff;font-size:17px;font-weight:700;margin-top:28px;\">10\u201315L agricultural sprayers<\/h3>\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">This is the core use case. Six 5215s on a hexacopter deliver 16+ kg of lift at hover with enough headroom at 75% throttle (33+ kg total) for gust recovery and terrain following. Besides that, the 8S voltage keeps BOM costs manageable for fleet operators who need to field multiple units.<\/p>\r\n\r\n<h3 style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#ffffff;font-size:17px;font-weight:700;margin-top:28px;\">Heavy-lift industrial quadcopters<\/h3>\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">Four 5215s with 13\u00d79\u00d73 props give you 8.5 kg of hover thrust at 1,420W total \u2014 certainly enough for a 4\u20135 kg payload on a 2.5 kg frame.

A 420KV motor on 6S (22.2V) spins at about 9,324 RPM unloaded versus roughly 13,440 RPM on 8S (29.6V).

Generally speaking, 15-inch gives you 6.7 g\/W at hover versus 6.0 g\/W for 13-inch \u2014 that is a 12% efficiency gain right there. But the 13-inch pulls 4 fewer amps at full throttle per motor, so if you have got prop clearance then go 15-inch. Otherwise, if your frame is tight or current headroom matters more to you than efficiency, then the 13-inch works fine.<\/p>\r\n\r\n<h3 style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#ffffff;font-size:17px;font-weight:700;margin-top:28px;\">What ESC do you recommend for the 5215-420KV?<\/h3>\r\n<p style=\"font-family:Segoe UI, Inter, system-ui, -apple-system, sans-serif;color:#d0d6e0;font-size:16px;line-height:1.75;\">Peak current on 15-inch props hits <strong style=\"color:#ffffff;font-weight:600;\">38.33A at 75% throttle<\/strong>, so a 60A-rated 8S ESC gives you comfortable margin.
