Brushless direct drive PicooZ experiment

August 23rd, 2009 RobZULU No comments

First step towards building a brushless direct drive 2.4Ghz gyro-ed PizooZ. The shaft of the HP03T 2.9 BL outrunner was replaced by a 50mm 1.5mm shaft that holds the picooZ main rotor. The picooZ rotor head was drilled to 1.5mm (stock is 1mm). The HP03T is normally used for the Walkera 4#3B brushless tail conversion. The motor is power by the flea converter.

Thrust at mid-stick is about 20g – about right, remains to be seen if the revomix works out.

I’m aiming for about 15g AUW for the 2Ch – if it works as planned this will be the platform for the acutator cyclics mod (see post here).

Amazingly quiet!
