It is a speed constant that only makes sense next to the pack voltage you actually fly. Buyers who pick a motor from peak thrust alone often discover the pairing later \u2014 on the bench, in a hot ESC, or in a return ticket.<\/p>\n<h2>What to lock before you quote<\/h2>\n<ul>\n<li>Nominal pack voltage and the cells you will ship with the airframe<\/li>\n<li>Prop diameter and pitch the customer will not change after delivery<\/li>\n<li>Continuous current the ESC and wiring can hold without derating<\/li>\n<\/ul>\n<p>When those three stay open, SKU selection turns into guesswork. Close them first, then shortlist motors inside the KV band that keeps tip speed and current in a sane window.<\/p>\n<h2>Where wrong pairing shows up<\/h2>\n<p>Too much KV on a high-voltage pack pushes current and heat. Too little KV on a light pack leaves thrust on the table and invites over-propping. Either path creates support load that looks like a product defect when it is really a system match error.<\/p>\n<p>If you are still lining up voltage and thrust targets, send the brief to <a href=\"\/es\/contact.html\/\">engineering<\/a> or start from the <a href=\"\/es\/products.html\/?cat=motors\">motor catalog<\/a>.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Match KV bands to pack voltage before you lock a SKU.
