Nearly Micro Plane

Hi,

I wand to present my nearly micro plane. It is a conversion of a toy delta. I got this as a present from the epp-fly guys in Aspach 2005. It had it's maiden flights two weeks ago with the motor in the 2nd picture (1st version).

1st version:
Wingspan: 40cm
Weight: 69g
Motor: 19x1.5mm, 25windings, 0.3mm wire, 3x1.5x1mm magnets (7.5g including the cut GWS prop)
Rx: Penta5
Servos: Blue Atom (grinded to 4g each)
Esc: MGM12A (stripped, removed heat sink, motor wires, shrink, 4g)
Bat: 2x340Kokam

This version flew quite well, but the motor quit above half power. Therefore I built a second version of the motor.

2nd version:
Motor: 20x3mm, 20 windings, 0.4mm wire, 4x3x1 magnets (9g, but the belt can be made lighter, the dividing head is allready on its way). This motor gives 90g of thrust with a Graupner Speed Cam Prop 10x8cm at 2.8A.
AUW: 72g
Maiden flight to come.

As I said: it is not really micro, but a very uncomplicated start.
