Most of the plans are based on a fan unit of 66 mm diameter.
In the past that meant buying a fan like the Mini Fan 480, cutting off the
outer ring (shroud) and carefully trimming down the stators and rotor. Now we do this job for you.
All that you need to do is build the ducting and glue in the stator.
Currently there are no measurements available for this unit but the MBM 505 consumes about 10% less current compared with the standard 70 mm Fan pro . Thrust is reduced by about the same amount.
This is usually fully compensated by one extra cell in the battery.
The exhaust pipe may be reduced to 52 mm diameter to achieve a higher efflux velocity.
Obviously, this fan unit may be used in other designs too. It saves a considerable amount of weight compared with the Mini Fan pro and especially with critical ducting situations it may show its advantages.

The 505 (speed 480 type) fan unit. The unit weighs a mere ounce, 28.5g to be exact. If you want fast Try this in the Wolverine, SV2, Pyanha, Baby Ru, F-5, Tornado, or Sniper.
