Thats some great discusion silversurfer.I appreciate your time invested into helping people with Taurus questions.I'll contact you or post here when I am ready for the next step,which is probably choosing and wiring and mounting the Ignition battery.I"ll need to stay light,as I have only a 80 inch wing on the extra,a battery that can provide 60 minutes of power should be enough,since I will probably only fly 3- 4 15 minute routines.Usually have something else at the field to fly also..
