Midi-Fan 80mm EVO, Impeller with mounted HET 650-68-2250

Modern multi-blade impeller with high efficiency.

This 80 mm impeller with a lightweight CfK casing is used wherever compact installation conditions are desired, and of course, especially in models designed for 80 mm impellers.

Of particular note here are the numerous foam models from various manufacturers on the market.
The Midi Fan80 evo is usually a classic "drop in" with minor adjustments, although foam models often feature impellers with a lip.

The unit presented here is optimal for jets up to approx. 4.2 kg and should be chosen especially if you are looking for a powerful 6s drive.

Included with the impeller are milled mounting tabs made of CFRP, which can be glued with epoxy resin (e.g. Uhu Endfest) at the desired position according to the installation situation.

The impeller comes fully assembled with an HET 650-68-2250 motor.
The unit is factory tested, finely balanced, and harmoniously tuned, so it can be used immediately.

Measurements:

• Voltage: 22.2Volt
• Current: 120A
• Power: 2664W
• Thrust: 3.35kp
• Jet velocity: 84.98m/s
• Efficiency: 0.53
• Controller: >130A
• Battery: 6000 - 8000mAh

Regarding the measurement conditions:
Measurements were taken with a stabilized voltage of 3.70 V / cell.
Current and thrust are based on measurements with a small lip (r=6 mm) at 21° C, 50m above sea level and standard atmospheric pressure.
Values may vary depending on the battery, ESC, and installation situation.

The ESC should be oversized by approximately 20% due to continuous load (based on the smaller ESC value).
LV = low volt ESCs up to 6s, HV = high volt ESCs from 7s
The battery is suitably sized at 1/15 - 1/20 of the current for 4-3 minutes of full throttle without reserve.
