SM110-47 EDF System

......................................................................................................................

The SM110-47 EDF System features a new 11 blade rotor which is designed for both lightness and aerodynamic efficiency. It has a 7 bladed carbon fibre stator assembly and a CNC machined motor tube which is designed for 39mm diameter motors of length right up to the HET 700-98 series. The rotor design has narrower blades than what would normally be expected, which allows cooler motor temperatures due to less torque demand. The HET 700-98 series motors are an excellent choice, and our first choice for factory built plug and play systems. The shroud is hand made solid carbon fibre. The carbon fibre stator assembly is bonded to the motor tube and shroud with aerospace grade methyl-methacrylate adhesive to ensure structural integrity even at high motor temperatures.

Note that the performance figures below are for HET motors, plug and play units are now fitted with the equivalent TP Power motor.

Performance:

HET 700-98-840kV motor: 12S 5000mAh lipos: 5500-6000WW Note: The carbon fibre tailcone pictured is no longer in production.

Note that these figures are taken on a test stand with a radiussed inlet lip and open exhaust. Your figures will be close but not exactly the same as a lot depends on the voltage your lipos deliver under load, the air temperature, humidity, altitude as well as inlet duct design and exhaust duct diameter
