Focke Wulf Ta 400, 4.35m, six lrk-torquemax diy homebuilt brushless motors

Have a look and a read at this beast by Soren Kjaer Nielssen. It will have six lrk-torquemax diy homebuilt brushless motors and 6! diy brushless controllers. Lots of pics on one page, be patient:

My Focke Wulf Ta 400 have the following data:
  • Build comlete in balsa covered with epoxi and light fiberglass (a few parts will be in waccum formed plastic).
  • Wingspan 4,35 m (app. 14.5‘)
  • Target weight is 12-14 kg.
  • 6 pcs. Robart mechanical retracts
  • Fowler flaps (can’t find information about the flaps on the real plane) I build the plane with fowler flaps because these flaps are a challenge to build, and they look and work very good in the air)
  • Motor: 6 pcs. S600 race 7.2v, 4.8:1 gearbox, 13x10 props (that is my standard motor/gearbox – if you have one of these motors, use it with a highrate gearbox, a big prop, and 10 cells…wow!!!) That was my target, but then Graupner, that supply this motor, changed the motor: The new S600 RACE 7,2v is not the same as the good old one !!!
    Therefore I have changed the 6 motors to homebuild brushless LRK 345-20 motors with homebuild speedy BL controllers, look at: LRK. and at: Speedy BL.
  • 60-72 RC2400 cells. (10-12/motor).
  • Expected flying time: 10 – 12 min
