The battery pack weighs in at about 3.7 ounces and the regulator 1.1 ounces. My wing panels weigh in at about 1#2 ounces each. One panel is a 1/2 ounce heavier than the other.
I will lose the wing spring in favor of 1/4-20 nylon thumb screws and nylon washer. With some of the changes i've made i'v removed 6 ounces. I still need to make a header bracket and apply some graphics along with the throttle servo and fuel filter.
I need to remove as much weight as possible. What could I set up differently?

Evan:
You didn't mention the weight of the HDswitch, or how you plan to power the CDI, but you should be able tosave weight in this setup with either a single or dual redundant Tech-Aero failsafe switch regulator setup.What are you using to power the CDI? I'm assuming that it's a separate switch and battery weighing several ounces. Instead, you can also take power for it from the receiver bus with an Ultra IBEC and eliminate the weight of the ignition battery and switch, and at the same time build in a way to switch the CDIpower on/off from the transmitter ANDset a failsafe condition to cut the engine. I fly a dual regulator, dual 850 mAh LiPo setup to power everything, with the Tech-Aero Ultra IBEC for the CDI and it weighs 5.4 oz in total.
You could also do it with a single failsafe switchTech-Aeroregulator, single battery (keep your existing 3.7 oz battery), eliminate the weight of the JR HDswitchand use the Ultra IBEC and it would come out to 5.2 oz total to power everything.
