Just got home, I don't have the Tacon... but here's a HW 4274SD 2200kv on the Tekno v4 D8. The motor is in the rear-most position make use of the Traktion Drive/Elektri-Clutch setup. As you can see in the pics, some room to spare even with the sensored wire...
Last pic included if you just plan to use just the standard pinions, the motor mount will be in the forward position.
