Gregg,

Too much. That is why I am selling my Smaragd-z plane. Can't afford two expensive play toys.

Hacker C50 XL motor - $415
Hacker Acro 90 speed controller - $400
TP 6000 10s3p batteries - $650
Two Astro 109 chargers - $260
Pyramid PS-26KX power supply - $100
APC E22-12 prop - $20
Misc. electrical connectors & wire - $20

The rest of the conversion costs are covered in my fuse repairs. Wow, does this engine have a totally linear and smooth power response. Gobs of torque at low RPM. Right now the plane flies so slow (but with plenty of power) that I can actually think ahead for my next maneuver. I real plus is how quiet the plane is.

Regards,

Steve
