Product FAQ
Which platforms is this SKU built for?

It targets industrial and distributor UAV programs that need clear specs, thermal margin, and repeatable production builds. Share duty cycle and AUW so we confirm the fit.

How do I choose the right configuration?

Match KV / config to pack voltage, prop diameter/pitch, and continuous current. Share duty cycle and AUW in the inquiry so we confirm the band before volume pricing.

What is the MOQ and when should I use Inquiry instead of Add to Cart?

Sample buys can use Add to Cart. Volume quote starts from 50 pcs on this SKU. Use Inquiry for dealer pricing, OEM marking, mixed lots, or when lead time and packing still need confirmation.

Can you support OEM marking and matched propulsion sets?

Yes. Logo, label language, wire length, and packing notes can be set early. We also help pair ESC class and prop size so sample and mass-production paths stay aligned.

Application scenarios

Built for teams that need continuous thrust and clear configuration options before locking a volume SKU.

Heavy-lift multirotor

Cargo and industrial airframes that run long duty cycles. Pair KV with prop load and continuous current before sample evaluation.

Manned / hybrid platforms

Manned and hybrid propulsion stacks where thermal margin and repeatable production builds matter more than hobby peak thrust.

Cinema & survey fleets

Multi-airframe fleets that restock the same motor family across seasons. Volume inquiry covers dealer pricing and staged ship windows.

OEM private-label programs

Marking, wire length, and packing language for partners that move from evaluation lots into annual forecasts.

Set and forget

Verified Purchase

Moved a heavy lifter onto AM32 100A 3-12S 4in1 ESC. FET temps looked calmer under the same hover load.

Manual is dense, but the PC tool is usable once you learn the layout.
